57-77: Good input validation for hex conversion.The
hexFileToByteshelper properly validates hex input (empty check, even length, valid characters) before conversion. The error messages are clear and specific.Consider adding JSDoc to clarify that the return type is a binary string (forge's byte string format):
+/** + * Converts hex-encoded file content to a binary byte string. + * @param value - Hex string to convert (with optional 0x prefix) + * @param label - Label for error messages + * @returns Binary string representation of bytes (forge format) + */ function hexFileToBytes(value: string, label: string): string {src/libs/network/endpointHandlers.ts (1)
56-58: Temporary type workaround acknowledged.The
anytype alias is explicitly marked as temporary. Consider creating a proper type definition in the workarounds module when the SDK export becomes available.src/libs/l2ps/L2PSBatchAggregator.ts (2)
343-347: Consider renamingencrypted_batchtoencoded_batchor clarifying the encryption.The field is named
encrypted_batchbut the actual operation is base64 encoding, not encryption. While the comment explains that individual transactions are already encrypted, the field name may cause confusion. Consider either:
- Renaming to
encoded_batchorbatch_datafor clarity- Adding encryption at the batch level if batch-level encryption is intended
519-531: Inconsistent SharedState access pattern.Line 529 uses
SharedState.getInstance()while line 369 usesgetSharedState. Consider using a consistent pattern throughout the class for maintainability.

src/model/entities/OfflineMessages.ts (1)
2-2: LGTM!Using
import typeis the correct approach sinceSerializedEncryptedObjectis only used as a type annotation. This ensures the import is erased during compilation and clarifies that it's purely for type checking.src/model/entities/GCRv2/GCRSubnetsTxs.ts (1)
2-2: LGTM! Clean import optimization.The removal of the unused
Transactionimport while keepingL2PSTransactionas a type-only import aligns with the PR's broader pattern of migrating to type-only imports for L2PS-related types.src/model/entities/Mempool.ts (1)
40-41: Verify TypeScript type compatibility with bigint column.The database column is now
bigint, but the TypeScript type remainsnumber. JavaScript'snumbertype has a safe integer range of ±2^53-1, while PostgreSQL'sbigintsupports ±2^63-1. If nonce values exceed the safe integer range, precision loss may occur.Consider updating the TypeScript type to match the database representation:
- @Column("bigint", { name: "nonce", nullable: true, default: 0 }) - nonce: number + @Column("bigint", { name: "nonce", nullable: true, default: 0 }) + nonce: bigintAlternatively, verify that nonce values in your use case will never exceed
Number.MAX_SAFE_INTEGER(9007199254740991).src/model/entities/Transactions.ts (1)
46-47: Verify TypeScript type compatibility with bigint column.Same concern as in
Mempool.ts: the database column isbigintbut the TypeScript type isnumber. This could lead to precision loss for nonce values exceedingNumber.MAX_SAFE_INTEGER.Consider updating to:
- @Column("bigint", { name: "nonce", nullable: true, default: 0 }) - nonce: number + @Column("bigint", { name: "nonce", nullable: true, default: 0 }) + nonce: bigintOr verify that nonce values will remain within the safe integer range.

1-2: LGTM! Import path consolidation.The migration of
L2PSTransactionto the@/types/sdk-workaroundspath and the use of type-only imports aligns with the PR's broader refactoring pattern for L2PS types.src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts (2)
57-57: LGTM! Necessary import for reference block retrieval.The addition of the
Chainimport is required to fetch the reference block number for mempool operations.
661-665: LGTM! Correctly implements updated mempool API.The change properly fetches the reference block number and includes it in the mempool transaction, aligning with the updated
Mempool.addTransactionsignature that now requiresreference_block: number.src/model/datasource.ts (2)
26-27: LGTM! New L2PS entity imports.The addition of
L2PSHashandL2PSMempoolTxentity imports supports the L2PS batch aggregation functionality introduced in this PR.
49-50: LGTM! Entities properly registered.Both L2PS entities are correctly registered in both DataSource configurations, ensuring they're available for TypeORM operations.
Also applies to: 83-84
src/libs/l2ps/parallelNetworks.ts (3)
13-14: LGTM! Import path consolidation.The migration of
L2PSTransactionto type-only import from@/types/sdk-workaroundsis consistent with the PR's refactoring pattern.
265-288: LGTM! New transaction encryption API.The
encryptTransactionmethod provides a clean public API for encrypting transactions. It properly:
- Awaits the asynchronous
encryptTxoperation (line 271)- Signs the encrypted transaction with the node's private key for integrity
- Accesses
getSharedStatecorrectly as a property (line 274)
185-191: Verify key format compatibility before merging.The change to read keys as hex-encoded strings and validate them through
hexFileToBytesis a security improvement, but this appears to be a breaking change if existing deployments use keys in a different format. Before approving, clarify:
- Are existing L2PS key files already hex-encoded, or will this require a migration?
- Is there migration guidance for existing deployments?
src/libs/consensus/v2/PoRBFT.ts (1)
388-393: LGTM! Handles transactions without GCR edits gracefully.The new logic correctly allows transactions without GCR edits (e.g., L2PS batch transactions) to pass through as successful without attempting to apply non-existent edits. This prevents potential errors from iterating over undefined or empty arrays.
src/libs/network/endpointHandlers.ts (2)
19-20: Import restructuring looks good.The type-only import for
L2PSTransactionfrom the SDK workarounds module aligns with the broader refactoring pattern in this PR.
126-131: GCREdit hashing optimization improves consistency.Precomputing the JSON strings before hashing both ensures identical input for comparison and avoids redundant serialization. This is a good change.
src/index.ts (4)
34-35: New L2PS service imports are correctly added.
388-393: L2PS network loading has error handling but continues on failure.The error is logged but doesn't prevent startup. This is appropriate for a non-critical service, but verify that downstream code (lines 397+) handles the case where
l2psJoinedUidsmay be empty or undefined if loading fails.
402-406: L2PSBatchAggregator service initialization looks correct.Starting the batch aggregator alongside the hash service when L2PS networks are present is the expected behavior.
422-429: Verify thatL2PSHashService.stop()andL2PSBatchAggregator.stop()are idempotent.The graceful shutdown correctly calls both services'
stop()methods with proper error handling. However, confirm that these methods use atomic state flags or similar guards to safely handle multiple invocations (e.g., when called during startup interruption, or if the handler fires twice). Idempotent stop() methods should complete without error or side effects when services weren't started or are already stopped. This is especially important for signal handlers that may be triggered concurrently.src/libs/peer/routines/getPeerIdentity.ts (4)
16-43: Helper types andasHexStringfunction handle identity format variations.The implementation handles colon-prefixed identities (e.g., "ed25519:0xabc...") and various prefix cases. The hex validation regex and normalization to lowercase with
0xprefix is correct.
97-113:normalizeExpectedIdentityprovides fallback for keys without prefix.The fallback for pure hex strings without
0xprefix ensures comparison works even with inconsistent input formats.
152-183: Identity comparison now uses normalized values consistently.The updated flow properly normalizes both received and expected identities before comparison, with appropriate null checks and logging. Assigning the normalized identity to
peer.identityensures consistent storage.
45-95: Comprehensive identity normalization handles multiple input formats.The function correctly handles strings, Uint8Array, ArrayBuffer, typed arrays, Node.js Buffer payloads, and envelope objects. The recursive call for
maybeEnvelope.datais appropriate.However, verify that
uint8ArrayToHexandasHexStringhandle the0xprefix consistently. Ifuint8ArrayToHexreturns0xabcdwhileasHexStringreturnsabcd(or vice versa), the final output will be inconsistent across different input types.src/model/entities/L2PSMempool.ts (1)
34-40: Newsequence_numbercolumn for deterministic ordering.Using
bigintwith string type in TypeScript matches thetimestamppattern and prevents JavaScript precision loss. The default value of"0"is appropriate.src/libs/blockchain/l2ps_mempool.ts (8)
10-26: Well-structured status lifecycle constants.The
L2PS_STATUSobject withas constassertion provides type-safe status values with clear lifecycle documentation:pending → processed → batched → confirmed → (deleted).
142-156: Improved block number determination with safer validation.The updated logic properly checks if
shardBlockRefis a valid non-negative number before use, and validateslastBlockNumberas a fallback. The additional safety check at lines 159-164 is defensive programming.
167-176: Timestamp stored as string for bigint column compatibility.Using
Date.now().toString()aligns with TypeORM's handling of bigint columns as strings to prevent JavaScript precision loss.
351-374: Batch status update is efficient for bulk operations.Using TypeORM's
In()operator for batch updates is the correct approach. The early return for empty arrays prevents unnecessary database calls.
389-410:getByStatusprovides efficient status-based querying.The method correctly applies optional limit with
takeand maintains consistent ordering by timestamp and hash.
453-473:deleteByHashescorrectly handles bulk deletion.Using
In()for batch delete with proper affected count handling.
482-506:cleanupByStatususes query builder for parameterized deletion.The cutoff timestamp is correctly converted to string for bigint column comparison. The parameterized query prevents SQL injection.
579-588: Cleanup method updated for string timestamp and uses status constant.Using
L2PS_STATUS.PROCESSEDinstead of a magic string improves maintainability.src/libs/l2ps/L2PSBatchAggregator.ts (15)

486-503: LGTM!Comprehensive statistics logging with safe division handling.
538-549: LGTM!Clean debug/test utility with appropriate guards.
369-375: VerifygetSharedStateis invoked correctly at line 369.Line 369 assigns
getSharedStatetosharedStatewithout parentheses. IfgetSharedStateis a function (rather than a getter or direct export), this will assign the function itself instead of the SharedState instance, causing line 372's property access to fail. Confirm the export type and apply parentheses if needed.
414-427: Type assertionas anyindicates potential type mismatch.The
as anycast at line 427 suggests thebatchTransactionobject doesn't match the expectedTransactiontype. This could mask type errors and lead to runtime issues if the mempool expects different fields. Verify that all required fields from theTransactioninterface are present in thebatchTransactionobject, or define a proper type instead of usingas any.

src/model/entities/L2PSMempool.ts (1)
14-17: Composite L2PS indexes now follow correct TypeORM usage; review need for separate single-column indexes.Defining the composite indexes at the class level with
["l2ps_uid", ...]correctly models common access patterns like(l2ps_uid, status)or(l2ps_uid, sequence_number)and fixes the earlier misuse of multi-column@Indexon a property.You now also have single-column indexes on
timestampandblock_numberin addition to the new composites. Depending on your query mix, some of these might be redundant and add write/storage overhead. It’s worth checking which patterns you actually use (e.g.,WHERE l2ps_uid = ? AND status = ?vsWHERE timestamp > ?) and pruning any indexes that don’t buy you query plans.src/libs/network/endpointHandlers.ts (1)
57-58: Track the temporarySubnetPayloadaliasThe temporary
SubnetPayload = anyalias is fine as a bridge, but once the proper type is exported from the SDK, this should be replaced (or removed if unused) to regain type safety on subnet/L2PS payloads.src/libs/l2ps/parallelNetworks.ts (1)
57-77:hexFileToBytescould align better with modern crypto patterns by returningUint8ArrayThe helper's validation is solid, but it currently returns a forge byte string (via
forge.util.hexToBytes), which is a legacy JavaScript pattern. While this works with L2PS's flexible parameter types (it acceptsstring | Buffer | Uint8Arrayfor IVs), adoptingUint8Arraywould provide better type safety and align with modern cryptographic libraries. Consider using a utility likeethers.utils.arrayify()or manual conversion (new Uint8Array(forge.util.hexToBytes(cleaned).split('').map(c => c.charCodeAt(0)))) to returnUint8Arrayinstead.src/libs/network/routines/transactions/handleL2PS.ts (3)
1-10: Import change to type-only L2PSTransaction looks good; consider minor consistency tweakThe new
import type { L2PSTransaction }aligns with TS best practices and avoids pulling runtime code for a type-only usage. For consistency and slightly leaner bundles, you might also consider switchingRPCResponseto a type-only import if it’s not used as a runtime value.
23-88: Validation, decryption, and signature verification flow is solid; consider tightening decryptedTx typingThe staged checks (L2PS UID presence, L2PS instance lookup, guarded
decryptTx, andTransaction.confirmTx) give a clear and defensible path for rejecting malformed or unauthorised L2PS traffic. One small improvement would be to givedecryptedTxan explicit transaction/interface type instead of leaving it implicitlyany, so that accesses likedecryptedTx.content.fromanddecryptedTx.hashare type-checked at compile time.
91-147: Improve duplicate handling and mempool write robustness; normalize error response shapeA few related points in this section:
There’s a TOCTOU window between
existsByOriginalHash(originalHash)and the subsequentaddTransaction(...): under concurrent submissions of the same L2PS payload, both calls can seeexistsByOriginalHash === falseand then race on insert. If the DB layer enforces uniqueness onoriginal_hash, it would be safer to rely on that and map the “duplicate insert” failure fromaddTransactionback to a 409, rather than pre-checking in application code.
addTransactionisn’t wrapped in atry/catch, unlikeexistsByOriginalHash. If it can throw (e.g., DB/network error), this will bubble up as an unhandled rejection instead of being surfaced as a structured RPC error. Mirroring theexistsByOriginalHashpattern here would make the failure mode clearer.For example:
const mempoolResult = await L2PSMempool.addTransaction(
l2psUid,l2psTx,originalHash,"processed",)
- let mempoolResult
- try {
mempoolResult = await L2PSMempool.addTransaction(l2psUid,l2psTx,originalHash,"processed",)- } catch (error) {
response.result = 500response.response = falseresponse.extra = `Mempool insert failed: ${error instanceof Error ? error.message : "Unknown error"}`return response- }
- For the “already processed” path (Lines 114‑118), `response.response` is a string, whereas other error branches use `false` and reserve the message for `extra`. If downstream consumers assume a boolean on failures, it might be worth standardizing this branch to match the others, keeping the human‑readable message in `extra`. Overall behaviour is correct, but tightening these points will make the handler more robust and predictable under load. </blockquote></details> </blockquote></details> <details> <summary>📜 Review details</summary> **Configuration used**: CodeRabbit UI **Review profile**: CHILL **Plan**: Pro **Disabled knowledge base sources:** - Linear integration is disabled by default for public repositories > You can enable these sources in your CodeRabbit configuration. <details> <summary>📥 Commits</summary> Reviewing files that changed from the base of the PR and between 32a0a8c9d313baf4e64693c2441d6c8867beae41 and a1082d18ef9d0ba4ec221000c9d7e0dc0357fec2. </details> <details> <summary>📒 Files selected for processing (5)</summary> * `src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts` (2 hunks) * `src/libs/l2ps/parallelNetworks.ts` (4 hunks) * `src/libs/network/endpointHandlers.ts` (4 hunks) * `src/libs/network/routines/transactions/handleL2PS.ts` (1 hunks) * `src/model/entities/L2PSMempool.ts` (3 hunks) </details> <details> <summary>🚧 Files skipped from review as they are similar to previous changes (1)</summary> * src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts </details> <details> <summary>🧰 Additional context used</summary> <details> <summary>🧬 Code graph analysis (2)</summary> <details> <summary>src/libs/network/endpointHandlers.ts (1)</summary><blockquote> <details> <summary>src/libs/crypto/hashing.ts (1)</summary> * `Hashing` (15-26) </details> </blockquote></details> <details> <summary>src/libs/l2ps/parallelNetworks.ts (1)</summary><blockquote> <details> <summary>src/utilities/sharedState.ts (1)</summary> * `getSharedState` (275-277) </details> </blockquote></details> </details> </details> <details> <summary>🔇 Additional comments (7)</summary><blockquote> <details> <summary>src/model/entities/L2PSMempool.ts (1)</summary><blockquote> `2-2`: **Type-only import for `L2PSTransaction` is a good fit here.** Using `import type` keeps this entity free of unnecessary runtime dependencies while still giving you strong typing on `encrypted_tx`, which is explicitly mapped as `"jsonb"` in TypeORM. </blockquote></details> <details> <summary>src/libs/network/endpointHandlers.ts (3)</summary><blockquote> `19-21`: **Type-only import for `L2PSTransaction` is appropriate here** Separating the value import (`Transaction`) from the type-only import (`L2PSTransaction`) keeps runtime bundle clean and matches how the type is used only in casts/annotations in this file. --- `126-132`: **GCREdit hashing refactor looks correct** Precomputing `gcrEditsString` and `txGcrEditsString` and hashing those keeps the two hash computations aligned and reduces the chance of subtle differences in serialization.

Clarify sequence_number semantics — sequencing is app-layer, not database-level.
The column is a plain bigint with default "0" and no database-side sequence or per-UID auto-incrementing. The actual sequencing is enforced in the L2PS batch logic (L2PSMempoolService.insertMempool() calculates the next sequence as max(existing) + 1 per l2ps_uid), so update the comment to reflect this app-layer behavior: "Monotonic sequence assigned per l2ps_uid by the L2PS batch logic; stored as bigint (surfaced as string in TypeScript for safe ordering)."
🤖 Prompt for AI Agents
In src/model/entities/L2PSMempool.ts around lines 34 to 40, the comment for
sequence_number incorrectly implies database-side auto-incrementing; update the
comment to state that sequencing is handled at the application layer (L2PS batch
logic via L2PSMempoolService.insertMempool(), which computes next sequence as
max(existing)+1 per l2ps_uid), and that the column is stored as a bigint with a
TypeScript string type for safe ordering/representation.

(id, data)columns, but none of the schemas incollectionSchemasdefine adatacolumn. For example, theactorstable has columnsid, type, name, inbox, outbox, followers, following, liked, notid, data.This will cause runtime SQL errors:
"table X has no column named data".The CRUD operations need to be updated to match the multi-column schemas defined in lines 6-23, or the schemas should be changed to use a two-column
(id, data)JSON-blob approach.Option 1: Update CRUD to match multi-column schemas
For example, for
actorscollection:- const sql = `INSERT INTO ${collection}(id, data) VALUES(?, ?)` - this.db.run(sql, [item.id, JSON.stringify(item)], function (err) { + // Dynamically build INSERT based on item properties + const columns = Object.keys(item).join(', ') + const placeholders = Object.keys(item).map(() => '?').join(', ') + const values = Object.values(item) + const sql = `INSERT OR REPLACE INTO ${collection}(${columns}) VALUES(${placeholders})` + this.db.run(sql, values, function (err) {Option 2: Change schemas to use JSON blob storage
private readonly collectionSchemas = { - actors: "id TEXT PRIMARY KEY, type TEXT, name TEXT, inbox TEXT, outbox TEXT, followers TEXT, following TEXT, liked TEXT", + actors: "id TEXT PRIMARY KEY, data TEXT", - objects: "id TEXT PRIMARY KEY, type TEXT, attributedTo TEXT, content TEXT", + objects: "id TEXT PRIMARY KEY, data TEXT", // ... apply to all collections }
62-77: Critical schema mismatch: SELECT returns incompatible structure.The
SELECT *statement returns all columns defined in the schema (e.g., foractors:id, type, name, inbox, outbox, followers, following, liked), but the original implementation likely expected adatacolumn containing a JSON blob that could be parsed.The current code on line 71 just assigns
rowdirectly without any transformation, which will return an object with multiple properties instead of the expected structure.This needs to be aligned with the chosen schema approach from the
saveItemfix. If using multi-column schemas, the callback should receive the structured object. If using JSON blob storage, the SELECT should parse thedatacolumn.src/libs/network/manageNodeCall.ts (1)

13-27: Strengthen value validation to truly enforce a “Uint8Array-like” shapeThe numeric-keyed record checks are a good improvement, but the current validation still allows values such as negatives, numbers >255, and non-integers (e.g.
1.75).Buffer.from(sortedValues)will silently coerce these, which is surprising for a function namedvalidateIfUint8Array.Consider tightening the checks along these lines:
- Require integer values:
Number.isInteger(val).- Require byte range:
val >= 0 && val <= 255.- Optionally, require non‑negative integer keys (to avoid
-1, etc.).Example diff sketch:
- const allValuesNumbers = entries.every(([, val]) => typeof val === "number") + const allValuesNumbers = entries.every(([, val]) => + typeof val === "number" && + Number.isInteger(val) && + val >= 0 && + val <= 255 + )This would make the “validated → Buffer” path much closer to the semantics of an actual
Uint8Arrayand avoid silent truncation/modulo behavior.
14-16: Minor: avoid repeatedNumber()conversions and consider non-negative key constraintYou convert string keys to numbers twice: once in
allKeysNumericIntegersand again in the sort comparator. To shave a bit of overhead and keep behavior consistent, you could:
- Either store the numeric key alongside each entry during validation, or
- Reuse the same conversion logic in a helper, ensuring identical rules for both validation and sort.
Also, if negative indices are never meaningful in your context, tightening the key check to
num >= 0would better match typical index semantics.This is minor, but would make intent clearer and avoid subtle drift between “valid key” and “sort key” behavior.
Also applies to: 24-26
src/libs/network/endpointHandlers.ts (2)
57-58: Track the temporarySubnetPayloadtype or use a more specific type.The
anytype bypasses TypeScript's type checking. Consider either:
- Using a more specific temporary type based on usage (e.g.,
Record<string, unknown>)- Creating a GitHub issue to track proper export from the SDK
- Adding a TODO comment with an issue number
Apply this diff:
-// TEMPORARY: Define SubnetPayload until proper export is available -type SubnetPayload = any +// TODO(#XXX): Replace with proper export from @kynesyslabs/demosdk/types +type SubnetPayload = { + l2ps_uid?: string; + encrypted_payload?: unknown; + [key: string]: unknown; +}
330-377: Consider extracting L2PS validation logic into a helper function.The validation checks follow a consistent pattern and could be refactored into a dedicated validation function to improve maintainability and testability. This would also make it easier to add new validation rules in the future.
Example refactor:
// Add new helper function at top level or in a utilities file function validateL2PSTransaction(tx: Transaction): { valid: boolean; error?: string } { if (!tx.signature?.data) { return { valid: false, error: "L2PS transaction requires valid signature" } } const l2psPayload = tx.content?.data?.[1] if (!l2psPayload || typeof l2psPayload !== "object") { return { valid: false, error: "Invalid L2PS payload structure" } } const senderAddress = tx.content?.from || tx.content?.from_ed25519_address if (!senderAddress) { return { valid: false, error: "L2PS transaction requires sender address" } } return { valid: true } } // Then in the switch case: case "l2psEncryptedTx": { console.log("[handleExecuteTransaction] Processing L2PS Encrypted Tx") const validation = validateL2PSTransaction(tx) if (!validation.valid) { log.error(`[handleExecuteTransaction] L2PS tx rejected: ${validation.error}`) result.success = false result.response = { error: validation.error } break } const l2psResult = await ServerHandlers.handleSubnetTx(tx as L2PSTransaction) // ... rest of logic }src/libs/blockchain/l2ps_mempool.ts (1)
173-179: Document the timestamp-as-string pattern or consider proper bigint handling.Storing
Date.now().toString()for bigint column compatibility is a workaround that requiresCASToperations in queries (see lines 491-501). While functional, this approach:
- Requires explicit CAST in every timestamp comparison
- Has performance implications for indexed queries
- Could be error-prone if CAST is forgotten
Consider either:
- Using a proper TypeORM bigint transformer:
@Column({ type: "bigint", transformer: { to: (value: number) => value?.toString(), from: (value: string) => value ? parseInt(value, 10) : 0 } }) timestamp: number
- If keeping current approach, add a prominent comment in the entity definition explaining why string storage is used and referencing the CAST requirements.

274-290: Add input validation fordata.domainand use consistent logging.The
resolveUdDomaincase should validate thatdata.domainis provided before calling the resolver, similar to other cases in this file. Also, uselog.errorfor consistency with the rest of the codebase.case "resolveUdDomain": { + if (!data.domain) { + response.result = 400 + response.response = "No domain specified" + break + } try { const res = await UDIdentityManager.resolveUDDomain(data.domain) if (res) { response.response = res } } catch (error) { - console.error(error) + log.error("[UD] Failed to resolve domain: " + error) response.result = 400 response.response = { success: false, error: "Failed to resolve web3 domain", } } break }src/libs/peer/routines/getPeerIdentity.ts (1)
232-238: Backward compatibility with security trade-off documented.The warning log for peers without challenge signatures is appropriate. However, ensure this backward compatibility mode is eventually deprecated once all peers support challenge-response.
Consider adding a configuration flag to enforce challenge-response in production:
// Future: Add config to enforce challenge-response // const REQUIRE_CHALLENGE_RESPONSE = process.env.REQUIRE_PEER_CHALLENGE === 'true'src/features/incentive/PointSystem.ts (1)
1041-1052: Duplicate domain check returns 200 instead of 400.When a domain is already linked, the response returns
result: 200with a message stating points were already awarded. This is inconsistent with other methods (e.g.,awardWeb3WalletPointsreturns 400 for already linked wallets at lines 339-342).Consider returning 400 for consistency with wallet linking behavior, or document why UD domains use a different pattern:
if (domainAlreadyLinked) { return { - result: 200, + result: 400, response: { pointsAwarded: 0, totalPoints: userPointsWithIdentities.totalPoints, message: "UD domain points already awarded", },src/libs/blockchain/gcr/gcr_routines/udIdentityManager.ts (3)
64-65: Remove empty constructor or add initialization logic.The empty constructor serves no purpose since the class only has static methods. Consider removing it entirely or making the class a namespace/module pattern.
export class UDIdentityManager { - constructor() {} - /** * Convert EVM domain resolution to unified format
396-399: Simplify isOwner boolean assignment.The double negation
!!is redundant when the result of===is already boolean.- const isOwner = !!( - signingAddress === - (resolution.metadata[signatureType] || {}).owner - ) + const isOwner = + signingAddress === resolution.metadata[signatureType]?.owner
690-697: Return typeanyreduces type safety.The
getIdentitiesmethod returnsPromise<any>which loses type information. Consider using a more specific type or generic.- static async getIdentities(address: string, key?: string): Promise<any> { + static async getIdentities( + address: string, + key?: string, + ): Promise<Record<string, unknown> | unknown> { const gcr = await ensureGCRForUser(address) if (key) { - return gcr.identities[key] + return gcr.identities[key] as unknown } - return gcr.identities + return gcr.identities as Record<string, unknown> }src/libs/blockchain/gcr/gcr_routines/udSolanaResolverHelper.ts (3)
308-311: Unsafe type assertion bypasses type checking.The
as anyassertion on the IDL could mask type mismatches between the IDL and theUnsSoltype definition.- this.program = new Program(UnsSolIdl as any,provider) as Program<UnsSol> + this.program = new Program<UnsSol>(UnsSolIdl as UnsSol, provider)If the IDL types don't align, consider regenerating the TypeScript types from the IDL using Anchor's type generation.
364-375: Redundant RPC call when data may already be available.Line 366 calls
connection.getAccountInfo()again for the same address that was just fetched on line 348-350. The data fromtokenAccountInfo.valueshould already contain the raw account data.// Fallback: parse raw token account data - if (tokenAccountInfo.value && "data" in tokenAccountInfo.value.data) { - const accountInfo = await connection.getAccountInfo(tokenAccounts.value[0].address) - - if (accountInfo && accountInfo.data.length >= 64) { + if (tokenAccountInfo.value && Buffer.isBuffer(tokenAccountInfo.value.data)) { + const data = tokenAccountInfo.value.data + if (data.length >= 64) { // SPL Token account layout: mint (32 bytes) + owner (32 bytes) + ... - const ownerBytes = accountInfo.data.slice(32, 64) + const ownerBytes = data.slice(32, 64) const owner = new PublicKey(ownerBytes).toString() log.debug(`Found domain owner via raw data: ${owner}`) return owner } }
260-270: Validation occurs after BigInt conversion.The validation on line 263 checks if
bigIntRecordVersion < 0but the conversion already happened on line 260. IfrecordVersionis invalid (e.g., NaN, negative), the BigInt conversion itself could throw. Consider validating before conversion.private deriveRecordPda( recordVersion: number, sldPda: PublicKey, recordKey: string, version = this.defaultVersion, ): PublicKey { - const bigIntRecordVersion = BigInt(recordVersion) - // Validate recordVersion before BigInt conversion to prevent TypeError - if (bigIntRecordVersion < BigInt(0)) { + if (!Number.isInteger(recordVersion) || recordVersion < 0) { throw new Error( - `Invalid record version: ${bigIntRecordVersion}. Must be a non-negative integer.`, + `Invalid record version: ${recordVersion}. Must be a non-negative integer.`, ) } + + const bigIntRecordVersion = BigInt(recordVersion) const versionBuffer = Buffer.alloc(8)

40-42: Unable to complete verification. Repository access required.src/utilities/validateUint8Array.ts (1)
2-5: Early-returning arrays/typed arrays changes behavior; confirm callers don’t rely on normalizationThe new
Array.isArray(input) || ArrayBuffer.isView(input)path now passes raw arrays,Buffer,Uint8Array,DataView, etc. straight through instead of normalizing them via the object-path logic. If any callers previously relied on “JSON-shaped” inputs (e.g.{"0":1,"1":2}) and plain arrays yielding aUint8Array/Buffer, this is a behavior change: arrays will now remainnumber[]and failinstanceof Uint8Arraychecks.Given how widely this kind of utility tends to be reused, it’s worth double-checking a few representative call sites to ensure they still behave as expected with the new early-exit semantics, especially around plain arrays and
DataView.src/features/activitypub/fedistore.ts (4)
5-23: Schema definitions look good, but verify CRUD alignment.The centralized schema registry is a good refactoring approach. Each collection has well-defined columns matching ActivityPub entity requirements.
33-36: Good use of single source of truth for validation.Initializing
validCollectionsfromcollectionSchemaskeys ensures the whitelist stays in sync with defined schemas. The initialization order is correct since this executes synchronously before any async database callbacks.
38-42: Effective whitelist validation for security.The validation method provides good protection against invalid collection names and potential SQL injection attacks on table names.
44-49: Table creation uses centralized schemas correctly.The iteration over
collectionSchemasproperly applies the defined column structures for each collection.src/libs/utils/demostdlib/groundControl.ts (1)
72-75: Insufficient path traversal protection—can be bypassed with multiple techniques.The current validation only checks for
..substrings, which is easily circumvented:
- Absolute paths:
/etc/passwd,/var/log/secretsbypass the check entirely- URL encoding:
%2e%2e,%2e%2e%2fwhen decoded by filesystem APIs- Path normalization:
....//,/./, or symbolic links- Case sensitivity: On case-insensitive filesystems, variations may work
An attacker controlling the
keysobject could read arbitrary files from the filesystem.Implement robust path traversal protection using
path.resolve()with directory whitelist validation, normalizing paths before access, and validating that resolved paths remain within an allowed certificate directory.src/features/activitypub/fediverse.ts (1)
2-7: LGTM! Good security enhancement.Adding Helmet middleware provides sensible security defaults (X-Content-Type-Options, X-Frame-Options, etc.). Placement before
express.json()is correct.src/libs/network/server_rpc.ts (1)
338-341: LGTM!This is a minor formatting change with no functional impact. The response payload remains unchanged.
package.json (3)
99-99: LGTM on tweetnacl addition.
tweetnacl ^1.0.3is a stable, well-audited cryptographic library commonly used for Ed25519 signature verification, aligning with the UD Solana verification flow described in the architecture patterns.
10-13: LGTM! Improved linting and type-checking scripts.The added scripts provide better developer tooling:
- Lint commands now properly ignore test directories.
- Type-check scripts using both Bun and tsc offer flexibility for CI/local workflows.
51-75: Address bs58 v6 ESM migration and verify demosdk version.
bs58 ^6.0.0: This major version switched to ESM-only and requires migration. Ensure your project is configured for ESM: add

126-132: LGTM - Clear refactor for deterministic hashing.Creating intermediate string variables before hashing improves clarity and makes the hashing inputs explicit. This ensures consistent string representation and makes debugging easier.
src/libs/blockchain/l2ps_mempool.ts (2)
16-31: Excellent TypeScript pattern for status lifecycle.The
as constassertion combined with the derivedL2PSStatustype provides strong type safety while maintaining string values for database storage. The lifecycle documentation in comments is also helpful.
356-379: Well-implemented batch status update.The method efficiently uses TypeORM's
Inoperator for bulk updates, includes proper error handling, and returns the affected count for caller verification. The empty array guard at the start prevents unnecessary database calls.src/libs/l2ps/L2PSBatchAggregator.ts (1)
16-29: Well-designed batch payload interface.The
L2PSBatchPayloadinterface is clearly documented with comprehensive JSDoc comments for each field. The inclusion ofauthentication_tagfor tamper detection andtransaction_hashesfor transparency is good design.src/features/mcp/MCPServer.ts (1)
21-21: LGTM - Security hardening with helmet middleware.Adding helmet middleware to the SSE transport Express app is a security best practice.

src/features/activitypub/fediverse.ts.Also applies to: 259-259
src/model/entities/GCRv2/GCR_Main.ts (1)
36-36: LGTM - Well-designed schema extension for UD domain points.The
udDomainsfield is appropriately marked as optional for backward compatibility with historical records. This allows existing GCR entries to continue functioning while supporting per-domain UD point tracking for new entries. The field structure{ [domain: string]: number }provides flexible per-domain point mapping.src/libs/blockchain/gcr/handleGCR.ts (1)
497-502: LGTM - Consistent identity schema extension for UD support.Adding
ud: []to the default identities structure extends GCRMain accounts to support Unstoppable Domains identity storage. The empty array default is appropriate and aligns with theStoredIdentitiestype extension introduced insrc/model/entities/types/IdentityTypes.ts. This change enables the UD identity management flows implemented elsewhere in the PR.src/libs/blockchain/gcr/gcr_routines/identityManager.ts (1)
329-336: LGTM - Type narrowing for identity key parameter.The union type
"xm" | "web2" | "pqc" | "ud"properly constrains the key parameter to valid identity categories, aligning with the new UD identity support. The implementation correctly accessesgcr.identities[key]..serena/memories/ud_security_patterns.md (1)
1-157: Good security documentation for UD domain handling.This documentation provides clear security patterns for UD domain ownership verification, including multi-chain considerations (EVM case-insensitive vs Solana case-sensitive), error handling patterns, and testing scenarios. The alignment with
UDIdentityManagerimplementation is correct.src/libs/network/routines/transactions/handleIdentityRequest.ts (2)
75-81: LGTM - UD identity assign handling follows established patterns.The implementation correctly delegates to
UDIdentityManager.verifyPayload()with proper type casting. The comment appropriately notes that UD follows signature-based verification like XM identities. Based on the relevant code snippet,verifyPayloadperforms comprehensive verification including domain resolution, address authorization, and signature validation.
97-101: LGTM - UD identity removal added to removal cases.Adding
ud_identity_removeto the existing removal case list is consistent with other identity types. The removal flow appropriately returns success, as the actual state changes are handled elsewhere in the GCR identity routines.src/libs/blockchain/gcr/gcr_routines/IncentiveManager.ts (1)
137-163: LGTM - UD domain incentive hooks follow established patterns.The
udDomainLinkedandudDomainUnlinkedmethods correctly mirror the pattern used for other identity types (Twitter, GitHub, Discord). The delegation toPointSystem.awardUdDomainPoints()anddeductUdDomainPoints()maintains proper separation of concerns.src/libs/network/manageNodeCall.ts (1)
255-255: Type assertion suggests SDK type mismatch.The
(tweet as any).idcast indicates a type safety issue where theTweettype doesn't include theidproperty. Consider updating the SDK types if available or creating a local extended interface to avoid theanycast.src/libs/blockchain/UDTypes/uns_sol.ts (1)
1-14: LGTM - Solana Anchor IDL type definition for UNS program.The type definition properly models the Solana UNS program's IDL structure for TypeScript usage. The documentation correctly notes this is a type helper, not the actual IDL.
The hardcoded program address at line 8 (
6eLvwb1dwtV5coME517Ki53DojQaRLUctY9qHqAsS9G2) should be verified to ensure it matches the expected production deployment of the UNS Solana program. Confirm this address against:
- The actual target/idl/uns_sol.json file referenced in the comments
- The production Solana deployment documentation
- Any environment-specific address configurations
src/model/entities/types/IdentityTypes.ts (2)
30-53: Well-documented interface for UD identity storage.The
SavedUdIdentityinterface is comprehensive with clear documentation of the Phase 5 changes. The breaking change fromresolvedAddresstosigningAddressis appropriately documented.

udproperty is correctly typed as an array ofSavedUdIdentity, maintaining consistency with other identity types in the structure.src/libs/blockchain/gcr/gcr_routines/GCRIdentityRoutines.ts (4)
541-565: Thorough validation for UD identity add operation.Good defensive validation of all required fields before processing. The explicit checks for each field ensure clear error messages when data is malformed.
645-695: UD identity removal looks correct.The removal logic properly validates the account exists, checks for existing domain, performs case-insensitive comparison, and triggers the appropriate incentive deduction.
893-909: UD first-connection check uses proper case-insensitive SQL.The LOWER() function in the SQL query ensures consistent domain matching regardless of case, aligning with the in-memory checks.
598-614: Potential TOCTOU race condition on domain uniqueness check.The domain existence check and subsequent push/save are not atomic. Two concurrent requests could both pass the
domainExistscheck before either saves, resulting in duplicate domains for the same account.Consider using a database-level unique constraint or wrapping the check-and-save in a transaction to prevent this race condition.

59-75: LGTM - Helper functions are well-designed.
validateAddressTypeandisSignableAddressare clean utility wrappers that follow the single responsibility principle.
23-46: Clean signature type detection with proper input validation.Good defensive programming with early guard for non-string inputs. The regex patterns correctly identify EVM (0x-prefixed 40 hex chars) and Solana (Base58 32-44 chars) addresses. The Base58 character set appropriately excludes 0, O, I, and l per Solana specifications.

normalizeIdentityfunction handles a wide variety of input formats (strings, Uint8Array, ArrayBuffer, Buffer payloads, envelope objects) and normalizes them to consistent lowercase hex strings. This is robust defensive coding.src/features/incentive/PointSystem.ts (4)
21-22: Point values for UD domains appropriately differentiated.
.demosdomains receive higher points (3) compared to other UD domains (1), incentivizing adoption of the platform's native TLD.
204-213: LGTM - udDomains breakdown handling correctly implemented.The initialization check and accumulation logic for UD domain points follows the same pattern as other point types.
1054-1092: Strong ownership verification for awarding points.Good security practice to verify:
- Domain exists in GCR identities (prevents race conditions)
- Domain is owned by user's linked wallets via
checkOwnerLinkedWalletsThis prevents point farming through unowned domains.
1152-1156: Verify ownership verification is skipped only whendeductUdDomainPointsis always called after GCR identity removal.The comment assumes ownership verification is redundant because GCRIdentityRoutines already verifies ownership via signature. However, this optimization is only valid if
deductUdDomainPointsis exclusively called as part of the identity removal flow. If this method can be invoked independently (e.g., through other code paths or administrative operations), the ownership check may be necessary to prevent points inflation from domain transfers. Confirm the calling context ofdeductUdDomainPointsacross the codebase to validate this assumption.src/libs/blockchain/gcr/gcr_routines/udSolanaResolverHelper.ts (1)
643-667: LGTM - Domain parsing and validation.The
resolveDomainconvenience method properly validates domain format before delegating toresolve(). The early return pattern with structured error responses is clean.src/libs/blockchain/gcr/gcr_routines/udIdentityManager.ts (1)
288-319: Hardcoded RPC URLs should be externalized and include fallback mechanisms for production reliability.Public RPC endpoints can become rate-limited, unavailable, or unreliable. Consider:
- Externalize endpoints via environment variables or configuration files
- Implement endpoint rotation and fallback logic with retry logic (exponential backoff + jitter)
- Add health checks or circuit breaker patterns to detect and skip unhealthy endpoints
- Use dedicated/premium RPC providers for critical operations, or maintain a pool of multiple endpoints

src/utilities/sharedState.ts (1)
85-88: Clarify thatl2psBatchNoncepersistence is process‑local onlyThe field works fine as an in‑memory counter for the aggregator, but it does not survive process restarts. Given the comment (“Persistent nonce…”) and how
getLastNonceFromStorageis documented/used, it may be worth clarifying that this is runtime/session persistence only, or wiring this through a durable store if true cross‑restart monotonicity is required.src/libs/l2ps/L2PSBatchAggregator.ts (2)
337-385: HMAC key derivation assumes Ed25519‑style raw byte private keys
createBatchPayloadnow correctly requires a private key and avoids the insecure fallback, but it assumessharedState.keypair.privateKeyis aUint8Array:const hmacKey = Buffer.from(sharedState.keypair.privateKey as Uint8Array) .toString("hex") .slice(0, 64)If other key types (e.g. RSA
forgeobjects) are ever used, this will throw at runtime. Consider either:
- Explicitly enforcing/validating that
signingAlgorithmis Ed25519 and the keypair is backed by raw byte keys before starting this service, or- Normalizing
privateKeyinto aUint8Arrayin one place (e.g.SharedState) and reusing that representation here.This keeps the aggregator resilient to future changes in key handling.
396-439: Nonce monotonicity is good per process, but comments overstate cross‑restart persistence
getNextBatchNoncecombinesDate.now() * 1000with the last stored nonce and saves viasharedState.l2psBatchNonce. This addresses the earlier in‑memory collision issues and gives a monotonically increasing sequence within a running process.However:
getLastNonceFromStorageonly reads from shared state, which is reset on process restart.- The doc comment says “persists the last used nonce … ensure uniqueness across restarts”, which is not strictly true without durable storage or reading back from chain/mempool.
If cross‑restart monotonicity is a hard requirement, consider persisting the last nonce in a DB (or deriving a lower bound from chain state) instead of only in memory. Otherwise, I’d suggest relaxing the comment to describe this as a timestamp‑based, best‑effort monotonic nonce with in‑process persistence.
src/libs/peer/routines/getPeerIdentity.ts (1)
176-285: Propagate getPeerIdentity failure semantics through verifyPeer
getPeerIdentitycan now returnnullon normalization or challenge‑verification failure, butverifyPeerignores that and always returns the originalpeer. Callers ofverifyPeertherefore have to remember to inspectpeer.verification.status(or related fields) instead of being able to rely on the return type, which is easy to miss.Consider tightening the API by either:
- changing
verifyPeerto returnPromise<Peer | null>and bubbling up thenullfromgetPeerIdentity, or- throwing on failure so callers must handle an explicit error.
That would make the verification contract clearer and reduce the chance of mistakenly treating an unverified peer as verified.

638-654: Consider adding explicit types for reduce accumulators.The reduce callbacks use implicit
anyfor the accumulator. Adding explicit types improves type safety.- const transactionsByUID = byUID.reduce((acc, row) => { + const transactionsByUID = byUID.reduce((acc: Record<string, number>, row) => { acc[row.l2ps_uid] = parseInt(row.count) return acc - }, {}) + }, {} as Record<string, number>)src/libs/l2ps/L2PSConsensus.ts (3)
269-277: Avoid dynamic imports - useL2PSProofManagerinstead.Dynamic imports inside a method add runtime overhead and complexity. Since
L2PSProofManageris already imported, consider adding aresetProofToPendingmethod there and using it here.Add to
L2PSProofManager:static async resetProofToPending(proofId: number): Promise<void> { const repo = await this.getRepo() await repo.update(proofId, { status: "pending", applied_block_number: null, processed_at: null }) }Then replace lines 269-277:

232-241: Inefficient query - filter by block number in database.Fetching 1000 proofs and filtering in memory is inefficient. Query directly with the block number filter.
Consider adding a method to
L2PSProofManagerthat filters byapplied_block_number:static async getAppliedProofsForBlock(blockNumber: number): Promise<L2PSProof[]> { const repo = await this.getRepo() return repo.find({ where: { applied_block_number: blockNumber, status: "applied" }, order: { created_at: "ASC" } }) }Then use it here:
- const appliedProofs = await L2PSProofManager.getProofs( - "", // all L2PS networks - "applied", - 1000 - ) - - // Filter by block number and rollback in reverse order - const proofsToRollback = appliedProofs - .filter(p => p.applied_block_number === blockNumber) - .reverse() + const proofsToRollback = (await L2PSProofManager.getAppliedProofsForBlock(blockNumber)).reverse()
291-304: Same inefficiency - use database-level filtering.Similar to

10-31: Well-structured status lifecycle constants.The lifecycle documentation and type derivation pattern are clean. The
as constassertion with derived type is idiomatic TypeScript.
114-193: LGTM - Solid transaction addition with proper validation.The method handles block number edge cases correctly, includes duplicate detection via both original and encrypted hashes, and stores timestamps as strings for bigint column compatibility.
src/libs/network/routines/transactions/handleL2PS.ts (3)
1-12: LGTM - Clean imports with new execution dependencies.The separation of
L2PSTransactiontype import and addition ofL2PSTransactionExecutorand logger are appropriate for the new execution phase.
139-160: Execution phase structure is sound.The try-catch pattern with status updates on failure is appropriate. The temporary use of
l2psTx.hashas the L1 batch reference with a clear comment about future updates is acceptable for the current implementation phase.
174-189: LGTM - Comprehensive response with privacy consideration.The response structure includes all relevant execution details while appropriately returning only the hash of the decrypted transaction rather than its full content, preserving L2PS privacy.
src/model/entities/L2PSTransactions.ts (3)
27-35: LGTM - Comprehensive indexing strategy.The multi-column indexes (UID+FROM, UID+TO) alongside single-column indexes provide efficient query paths for common L2PS transaction lookups.
98-114: LGTM - Appropriate use of bigint for large numeric values.Using
bigintfor amount, nonce, and timestamp is correct for handling values that may exceed JavaScript's safe integer limit.
116-124: Consider aligning status values withL2PS_STATUSconstants if both entities track the same transaction lifecycle.This entity uses a hardcoded union type for status ("pending" | "batched" | "confirmed" | "failed"), while
L2PS_STATUSconstants define additional statuses ("processed", "executed"). If both entities represent the same lifecycle, consolidating to a shared type would improve maintainability. If they intentionally represent different stages (e.g., mempool vs. finalized transactions), document this distinction to prevent future confusion.src/libs/l2ps/L2PSConsensus.ts (2)
26-45: LGTM - Well-defined consensus result interface.The
L2PSConsensusResultinterface comprehensively captures the outcome of proof applications, including per-proof details for debugging and monitoring.
184-196: Rollback logic is correct.The loop correctly starts at
editResults.length - 2to skip the failed edit and iterates backwards, rolling back only successfully applied edits. TheisRollback: trueflag properly signals toHandleGCR.applythat this is a reversal operation.src/model/entities/L2PSProofs.ts (1)
44-143: LGTM - Well-structured proof entity.The entity comprehensively captures the L2PS proof lifecycle with appropriate fields for tracking creation, application, and rejection states. Documentation is thorough and nullable fields are correctly annotated.
src/libs/l2ps/L2PSTransactionExecutor.ts (2)
57-77: Lazy initialization pattern looks correct.The singleton-style initialization with
initPromiseproperly handles concurrent initialization attempts and avoids race conditions. The pattern correctly checks for bothl1RepoandinitPromiseto prevent redundant initialization.
339-371: Add error handling for duplicate transaction hashes.The
saveoperation may fail or create duplicates iftx.hashalready exists, depending on whether unique constraints are defined on the hash field. Add validation to check for existing records before saving, or implement upsert logic to prevent data integrity issues.src/libs/l2ps/L2PSProofManager.ts (3)
222-262: Proof verification logic looks sound for placeholder implementation.The verification properly validates structure, checks required fields on GCR edits, and uses
deterministicStringifyfor consistent hash comparison. The placeholder approach is well-documented with TODO for future ZK verification.
70-93: Initialization pattern is consistent and correct.The lazy singleton initialization with
initPromiseproperly handles concurrent calls, matching the pattern used inL2PSTransactionExecutor. This ensures thread-safe repository initialization.
29-39: No changes needed. ThedeterministicStringifyfunction correctly handles nested objects within arrays because JSON.stringify's replacer function is invoked for every value during serialization, including objects nested inside arrays. The conditionif (value && typeof value === 'object' && !Array.isArray(value))will match and sort keys for all such nested objects before serialization, ensuring consistent output regardless of original key ordering.Likely an incorrect or invalid review comment.

getProofsForBlock ignores the blockNumber parameter.

status:"pending" (keeping the ASC order), ensuring types match; alternatively,
if no per-block filtering is required, remove the blockNumber parameter and

Object.keys(value).sort()may produce inconsistent results with non-ASCII characters or locale-specific orderings. UselocaleComparefor deterministic cross-platform sorting.Apply this diff:
function deterministicStringify(obj: any): string { return JSON.stringify(obj, (key, value) => { if (value && typeof value === 'object' && !Array.isArray(value)) { - return Object.keys(value).sort().reduce((sorted: any, k) => { + return Object.keys(value).sort((a, b) => a.localeCompare(b)).reduce((sorted: any, k) => { sorted[k] = value[k] return sorted }, {}) } return value }) }src/libs/l2ps/L2PSTransactionExecutor.ts (1)
113-223: Consider reducing cognitive complexity ofexecute()method.Static analysis flags cognitive complexity of 31 (allowed: 15). While the logic is readable, consider extracting the switch-case handling into separate methods (e.g.,
handleDemosWorkTransaction,handleDefaultTransaction) to reduce complexity and improve testability.Example extraction pattern:
private static async handleTransactionByType( tx: Transaction, simulate: boolean ): Promise<{ gcrEdits: GCREdit[]; affectedAccounts: string[] } | L2PSExecutionResult> { switch (tx.content.type) { case "native": return this.handleNativeTransaction(tx, simulate) case "demoswork": return this.handleDemosWorkTransaction(tx, simulate) default: return this.handleGenericTransaction(tx, simulate) } }

src/libs/network/routines/transactions/handleL2PS.ts (1)
139-172: LGTM - Execution flow and status updates correctly implemented.The execution flow properly integrates with
L2PSTransactionExecutorand uses the correct hash (l2psTx.hash) for allupdateStatuscalls, matching the hash stored duringaddTransaction. The previous bug whereoriginalHashwas incorrectly used has been addressed.src/libs/blockchain/l2ps_mempool.ts (3)
10-31: LGTM - Well-defined status lifecycle.The status constants and type are properly structured with clear documentation of the lifecycle flow. The
as constassertion ensures type safety.
356-379: LGTM - Batch update operation is well-implemented.Handles empty array edge case, uses
In()operator efficiently, and properly returns the affected count with appropriate logging.
584-593: LGTM - Timestamp comparison fixed.The cleanup method now uses
CAST(timestamp AS BIGINT) < CAST(:cutoff AS BIGINT)for proper numeric comparison, consistent withcleanupByStatus. This addresses the previously flagged string comparison issue.src/libs/l2ps/L2PSProofManager.ts (2)
115-118: LGTM - Deterministic hash generation.The
transactionsHashnow usesdeterministicStringifywith stable inputs (l2psUid,l1BatchHash,gcrEdits), addressing the previous concern about non-deterministicDate.now()usage.
222-262: LGTM - Placeholder verification is correctly structured.The verification logic properly validates proof structure, GCR edit fields, and uses deterministic hashing for placeholder proof comparison. The TODO for actual ZK verification is appropriately documented.
src/libs/l2ps/L2PSTransactionExecutor.ts (4)
127-174: LGTM - Switch cases properly scoped with blocks.The switch cases now use block scoping (braces) for the
nativeanddefaultcases, addressing the previous concern about variable hoisting and temporal dead zone issues.
237-294: LGTM - Native transaction handling with proper validation.Switch cases are properly block-scoped, and amount validation at line 243 includes comprehensive type checking (
typeof,Number.isFinite, positive check), addressing the previous review concerns.
307-339: LGTM - Unused variable removed, validation properly structured.The previously flagged unused
repovariable has been replaced with a properinit()call. The validation logic for balance edits correctly checks L1 state sufficiency.
381-402: LGTM - Status update now handles missing records.The method now checks
result.affectedand logs a warning when no transaction is found, addressing the previous concern about silent success on non-existent records.

451-531: Address reference_block and publicKey casting concerns from previous review.Two issues from the previous review remain unresolved:
Line 508:
reference_block: 0— The comment suggests mempool will set this, but according to prior review analysis,Mempool.addTransactionpasses this value through without recalculation. Batch transactions will persist withreference_block = 0, potentially bypassing anchoring/ordering semantics. Set a meaningful reference block here (e.g.,sharedState.lastKnownBlockor query latest block height) instead of relying on downstream logic.Line 462: Unsafe publicKey cast — Casting
sharedState.keypair.publicKey as Uint8Arraywithout validation will fail at runtime if the key isn't aUint8Array. Either reusesharedState.publicKeyHex(preferred) or add type validation before casting.Based on prior review feedback at lines 451-531.
🧹 Nitpick comments (11)
src/libs/l2ps/L2PSConcurrentSync.ts (1)
167-188: Batch duplicate detection improves sync performance.The pre-fetch approach to check for existing hashes before per-transaction insertion is a good optimization. However, consider adding a guard for empty
txHashesarray to avoid unnecessary database queries.// Batch duplicate detection: check all hashes at once const txHashes = transactions.map(tx => tx.hash) const existingHashes = new Set<string>() + if (txHashes.length === 0) { + log.debug("[L2PS Sync] No transaction hashes to check for duplicates") + return + } + // Query database once for all hashes try {src/libs/l2ps/parallelNetworks.ts (1)
55-75: Well-structured hex validation helper.The
hexFileToBytesfunction properly validates hex input with comprehensive checks for empty values, odd length, and non-hex characters. Per SonarCloud hint, consider usingreplaceAllfor clarity.- const cleaned = value.trim().replace(/^0x/, "").replace(/\s+/g, "") + const cleaned = value.trim().replace(/^0x/, "").replaceAll(/\s+/g, "")src/libs/blockchain/l2ps_mempool.ts (1)
626-629: Type safety concern withparseIntin stats aggregation.The
parseInt(row.count)assumes the database returns a string, which is typical for aggregate results, but consider usingNumber()for robustness or adding type annotations.const transactionsByUID = byUID.reduce((acc, row) => { - acc[row.l2ps_uid] = parseInt(row.count) + acc[row.l2ps_uid] = Number(row.count) return acc - }, {}) + }, {} as Record<string, number>)src/libs/l2ps/L2PSConsensus.ts (4)
68-161: High cognitive complexity inapplyPendingProofs.This function exceeds the complexity threshold (20 vs 15 allowed). Consider extracting the proof result processing (lines 94-107) and the post-processing logic (lines 113-148) into separate helper methods.
+ /** + * Process individual proof results and update counters + */ + private static processProofResult( + result: L2PSConsensusResult, + proofResult: { success: boolean; editsApplied: number }, + proof: L2PSProof + ): void { + if (proofResult.success) { + result.proofsApplied++ + result.totalEditsApplied += proofResult.editsApplied + result.affectedAccounts.push(...proof.affected_accounts) + } else { + result.proofsFailed++ + result.success = false + } + }
167-264: High cognitive complexity inapplyProofwith nested rollback logic.The function has complexity of 24 (exceeds 15). The rollback logic (lines 228-238) is particularly complex. Consider extracting it to a dedicated helper.
+ /** + * Rollback previously applied edits on failure + */ + private static async rollbackAppliedEdits( + editResults: GCRResult[], + gcrEdits: GCREdit[], + mockTx: any + ): Promise<void> { + for (let i = editResults.length - 2; i >= 0; i--) { + if (editResults[i].success) { + const rollbackEdit = { ...gcrEdits[i], isRollback: true } + await HandleGCR.apply(rollbackEdit, mockTx, true, false) + } + } + }
289-300: Use explicit compare function for deterministic sorting.For deterministic hash ordering across all environments, use
localeCompareas flagged by static analysis.- proof_hashes: proofs.map(p => p.transactions_hash).sort(), + const sortedProofHashes = proofs.map(p => p.transactions_hash).slice().sort((a, b) => a.localeCompare(b)) transaction_count: totalTransactions, ... const batchHash = Hashing.sha256(JSON.stringify({ blockNumber, - proofHashes: batchPayload.proof_hashes, - l2psNetworks: l2psNetworks.sort() + proofHashes: sortedProofHashes, + l2psNetworks: l2psNetworks.slice().sort((a, b) => a.localeCompare(b)) }))
394-402: Dynamic imports in rollback path may impact performance.Using dynamic imports inside the rollback loop adds latency to an already critical recovery path. Consider caching the repository reference or initializing it once at the start of
rollbackProofsForBlock.static async rollbackProofsForBlock(blockNumber: number): Promise<void> { try { + // Initialize repository once at the start + const repo = await (await import("@/model/datasource")).default.getInstance() + const ds = repo.getDataSource() + const proofRepo = ds.getRepository((await import("@/model/entities/L2PSProofs")).L2PSProof) + // Get proofs that were applied in this block const appliedProofs = await L2PSProofManager.getProofs(Then use
proofRepodirectly inside the loop instead of re-importing.src/libs/l2ps/L2PSTransactionExecutor.ts (1)
113-226: High cognitive complexity inexecutemethod.The function has complexity of 31 (exceeds 15 allowed). Consider extracting the switch case handling into a dedicated method like
processTransactionByType.+ /** + * Process transaction based on type and generate GCR edits + */ + private static async processTransactionByType( + tx: Transaction, + simulate: boolean + ): Promise<{ gcrEdits: GCREdit[]; affectedAccounts: string[] } | L2PSExecutionResult> { + const gcrEdits: GCREdit[] = [] + const affectedAccounts: string[] = [] + + switch (tx.content.type) { + case "native": { + const result = await this.handleNativeTransaction(tx, simulate) + if (!result.success) return result + gcrEdits.push(...(result.gcr_edits || [])) + affectedAccounts.push(...(result.affected_accounts || [])) + break + } + // ... other cases + } + return { gcrEdits, affectedAccounts } + }src/libs/l2ps/L2PSBatchAggregator.ts (3)
1-10: Clean up duplicate imports and prefernode:crypto.Two minor import improvements:
- Lines 4-5 import from
@/utilities/sharedStatetwice—merge into a single import statement.- Line 9 uses
cryptoinstead ofnode:crypto. Thenode:prefix is the modern Node.js convention for built-in modules.Apply this diff:
-import SharedState from "@/utilities/sharedState" -import { getSharedState } from "@/utilities/sharedState" +import SharedState, { getSharedState } from "@/utilities/sharedState" import log from "@/utilities/logger" import { Hashing, ucrypto, uint8ArrayToHex } from "@kynesyslabs/demosdk/encryption" import { getNetworkTimestamp } from "@/libs/utils/calibrateTime" -import crypto from "crypto" +import crypto from "node:crypto"
79-80: Remove unusedbatchNonceCounterfield.The
batchNonceCounterfield at line 80 is never used—the persistent nonce implementation usesSharedState.l2psBatchNonceinstead (lines 396-439). This appears to be leftover from the refactoring that addressed the nonce persistence issue.Apply this diff:
/** Domain separator for batch transaction signatures */ private readonly SIGNATURE_DOMAIN = "L2PS_BATCH_TX_V1" - /** Persistent nonce counter for batch transactions */ - private batchNonceCounter: number = 0 - /** Statistics tracking */ private stats = {
431-438: Improve error logging in nonce storage.Line 437 logs the error directly in a template literal, which will use
Object.toString()and may produce uninformative output like[object Object]. Useerror.messageorerror.stackfor better diagnostics.Apply this diff:
} catch (error) { - log.warning(`[L2PS Batch Aggregator] Failed to persist nonce: ${error}`) + log.warning(`[L2PS Batch Aggregator] Failed to persist nonce: ${error instanceof Error ? error.message : String(error)}`) }

🔇 Additional comments (27)
src/libs/l2ps/L2PSConcurrentSync.ts (2)
119-119: LGTM: Log level consistency update.The change from
log.warntolog.warningaligns with the logging API used elsewhere in the L2PS codebase.
190-222: Transaction insertion flow is well-structured.The duplicate filtering before insertion and the graceful handling of
addTransactionfailures (distinguishing between duplicates and other errors) is appropriate.src/libs/l2ps/parallelNetworks.ts (4)
108-132: Good race condition prevention with loading promise lock.The pattern of storing loading promises to prevent concurrent
loadL2PScalls for the same UID is appropriate. The promise is correctly cleaned up in thefinallyblock.
141-198: Security-conscious configuration loading.Path traversal validation (lines 143-148) and comprehensive key file validation (lines 166-179) are good security practices. The hex-to-bytes conversion for cryptographic material is properly handled.
260-283: Encryption flow with proper signing.The
encryptTransactionmethod correctly awaits the async encryption and signs the result with the node's private key. The signature attachment pattern is consistent.
336-352: Safe array destructuring with validation.Good defensive programming - validating the array structure before destructuring prevents runtime errors from malformed transaction data.
src/libs/blockchain/l2ps_mempool.ts (3)
10-31: Well-defined status lifecycle constants.The
L2PS_STATUSobject withas constassertion provides type safety and the documented lifecycle flow is clear:pending → processed → executed → batched → confirmed.
347-370: Efficient batch status update implementation.The
updateStatusBatchmethod correctly uses TypeORM'sInoperator for bulk updates and includes proper early return for empty arrays.
478-502: Consistent timestamp comparison in cleanup.The
CAST(timestamp AS BIGINT)approach ensures correct numeric comparison for string-stored timestamps, matching the pattern in thecleanupmethod.src/libs/l2ps/L2PSHashService.ts (2)
224-228: Log level consistency maintained.The change to
log.warningaligns with the logging convention used across the L2PS codebase.
98-99: Demos instance initialization is appropriately placed.Initializing the Demos SDK instance once during service start and reusing it for all hash update transactions is efficient.
src/model/entities/L2PSProofs.ts (1)
38-49: Entity structure and indexes are well-defined.The index naming is now consistent (
IDX_L2PS_PROOFS_*) and the compound index on[l2ps_uid, status]will optimize common query patterns.src/libs/l2ps/L2PSTransactionExecutor.ts (4)
57-72: Lazy initialization pattern is correct.The check
if (this.initPromise)correctly tests for existence of an ongoing initialization, not the promise's resolved value. This prevents multiple concurrent initializations.
240-297: Single-case switch is intentional for extensibility.While static analysis suggests using
ifstatements, the switch structure anticipates future native operations beyond "send". The current implementation is acceptable.
399-405: Good: Update result verification implemented.The check for
result.affected === 0addresses the previous review feedback about silent success when no rows match.
264-281: GCR edits correctly capture transfer semantics.The debit/credit pair with proper account references and transaction hash linking follows the expected pattern for balance modifications.
src/libs/l2ps/L2PSBatchAggregator.ts (5)
11-29: Well-structured batch payload interface.The L2PSBatchPayload interface is clear and well-documented. The combination of encrypted_batch, batch_hash, and authentication_tag provides both confidentiality and integrity verification.
116-183: Solid lifecycle management with graceful shutdown.The start/stop methods properly handle:
- Service state validation
- Reentrancy protection with
isAggregatingflag- Graceful shutdown with configurable timeout
- Statistics reset on restart
235-262: Clean aggregation logic with proper grouping.The aggregation workflow is well-structured:
- Fetch executed transactions
- Group by L2PS UID
- Process each network's batch independently
This allows multiple L2PS networks to be batched in the same cycle efficiently.
337-385: HMAC generation properly secured.The HMAC fallback issue from previous reviews has been correctly addressed. The code now throws an error if the keypair is unavailable (line 364-365), ensuring batch authentication always uses proper cryptographic material.
540-637: Comprehensive statistics and clean public API.The cleanup, statistics tracking, and public API methods are well-designed:
cleanupOldBatchedTransactions()prevents unbounded growth- Statistics provide operational visibility
getStatus()andgetStatistics()enable monitoringforceAggregation()supports testing/debuggingsrc/libs/l2ps/L2PSProofManager.ts (6)
44-59: Clear result interfaces.The
ProofCreationResultandProofApplicationResultinterfaces provide clean, type-safe return values with optional fields for success cases and required error messages.
106-172: Deterministic proof creation properly implemented.The
createProofmethod correctly addresses the previous review concern about non-deterministic hashing. Lines 118-120 and 127-133 now usedeterministicStringifywithoutDate.now(), ensuring the same inputs always produce the same hash.
201-212: Block-specific filtering documented as future work.The
blockNumberparameter is currently unused (line 204 TODO), but this is clearly documented as intended for future block-specific batching. The method signature reserves this parameter to avoid breaking changes later.Note: The TODO at line 204 represents planned functionality rather than forgotten work.
225-265: Placeholder verification with solid structural validation.The current verification implementation provides:
- Basic structure validation (lines 228-231)
- GCR edit field validation (lines 234-240)
- Hash consistency checks for placeholder proofs (lines 245-258)
The TODO at line 242 documents the future ZK verification work, which is appropriate for this phase.
273-301: Clean proof status transitions.The
markProofAppliedandmarkProofRejectedmethods properly handle proof lifecycle transitions with timestamps and appropriate logging.
309-365: Efficient query methods with proper filtering.The query methods are well-implemented:
getProofByBatchHashfor L1 batch lookupsgetProofswith flexible filtering by UID and statusgetStatsefficiently usesPromise.allwith cloned query builders (lines 357-362) for parallel counts

TypeORM JSONB column default value array syntax
💡 Result:
Use a JSONB (not a Postgres array) and set the default as a raw SQL expression. Example:
@column({
type: 'jsonb',
array: false,
default: () => "'[]'",
nullable: false,
})
users: { id: string }[] = [];
Notes:
- Omitting array:false can make TypeORM create jsonb[] (Postgres array of jsonb) which causes malformed-array errors when you try to store a JSON array. [1]
- The default must be a raw DB expression (hence default: () => "'[]'"); you can also use "'[]'::jsonb" if you prefer an explicit cast. [1][2]
Sources:
[1] StackOverflow — TypeORM jsonb array column (example and fix).
[2] TypeORM docs — Postgres column types.
Fix JSONB default value to use raw SQL expression.
The string literal "[]" will not produce the correct JSONB default at the database level. TypeORM requires JSONB defaults to be raw SQL expressions.
- @Column("jsonb", { default: "[]" })
+ @Column("jsonb", { default: () => "'[]'" })

In src/model/entities/L2PSProofs.ts around lines 126 to 131, the Column
decorator uses the string literal default: "[]" which does not set a proper
JSONB default at the DB level; change the default to a raw SQL expression or
casted literal (e.g., use TypeORM's function form like default: () =>
"'[]'::jsonb") so the database column receives a true jsonb empty array default;
update the @Column(...) options accordingly and run migrations or sync to apply
the corrected default.

354-411: Dynamic imports inside rollback loop are inefficient and error-prone.The dynamic imports at lines 394-396 are executed inside the
forloop, which:
- Creates unnecessary overhead by importing the same modules multiple times
- Could fail partway through rollback, leaving state inconsistent
Move imports outside the loop:
static async rollbackProofsForBlock(blockNumber: number): Promise<void> { try { + // Import once before the loop + const repo = await (await import("@/model/datasource")).default.getInstance() + const ds = repo.getDataSource() + const { L2PSProof: L2PSProofEntity } = await import("@/model/entities/L2PSProofs") + const proofRepo = ds.getRepository(L2PSProofEntity) + // Get proofs that were applied in this block const appliedProofs = await L2PSProofManager.getProofs( "", // all L2PS networks "applied", 1000 ) // ... rollback logic ... for (const proof of proofsToRollback) { // ... rollback each edit ... - // Reset proof status to pending - const repo = await (await import("@/model/datasource")).default.getInstance() - const ds = repo.getDataSource() - const proofRepo = ds.getRepository((await import("@/model/entities/L2PSProofs")).L2PSProof) - await proofRepo.update(proof.id, { status: "pending", applied_block_number: null, processed_at: null }) }
416-429:getBlockStatsfetches all applied proofs with high limit - potential performance issue.This method fetches up to 10,000 proofs and filters in memory. For a production system with many blocks and proofs, this could be slow and memory-intensive.
Consider adding a database-level filter for
applied_block_number:static async getBlockStats(blockNumber: number): Promise<{ proofsApplied: number totalEdits: number affectedAccounts: number }> { - const appliedProofs = await L2PSProofManager.getProofs("", "applied", 10000) - const blockProofs = appliedProofs.filter(p => p.applied_block_number === blockNumber) + // Use direct query with block filter for efficiency + const repo = await (await import("@/model/datasource")).default.getInstance() + const ds = repo.getDataSource() + const proofRepo = ds.getRepository((await import("@/model/entities/L2PSProofs")).L2PSProof) + + const blockProofs = await proofRepo.find({ + where: { status: "applied", applied_block_number: blockNumber } + }) return { proofsApplied: blockProofs.length, totalEdits: blockProofs.reduce((sum, p) => sum + p.gcr_edits.length, 0), affectedAccounts: new Set(blockProofs.flatMap(p => p.affected_accounts)).size } }src/libs/l2ps/L2PSTransactionExecutor.ts (1)
138-155:demosworkcase missing block scope - inconsistent with other cases.The
case "demoswork":anddefault:cases at lines 138 and 157 are not wrapped in blocks, unlikecase "native":. While these cases don't declare variables that would cause TDZ issues currently, adding blocks would maintain consistency and prevent future issues.- case "demoswork": + case "demoswork": { if (tx.content.gcr_edits && tx.content.gcr_edits.length > 0) { // ... } break + } - default: + default: { if (tx.content.gcr_edits && tx.content.gcr_edits.length > 0) { // ... } + }src/libs/l2ps/L2PSProofManager.ts (1)
352-364: QueryBuilder cloning may cause unexpected behavior in parallel execution.The
getStatsmethod clones the query builder multiple times for parallelgetCount()calls. While this works, TypeORM'sclone()shares some internal state. The parallel execution withPromise.allshould be safe here, but consider using separate query builders if issues arise.For maximum safety, use separate query builders:
static async getStats(l2psUid?: string): Promise<{ pending: number applied: number rejected: number total: number }> { const repo = await this.getRepo() + + const baseWhere = l2psUid ? { l2ps_uid: l2psUid } : {} const [pending, applied, rejected, total] = await Promise.all([ - queryBuilder.clone().andWhere("proof.status = :status", { status: "pending" }).getCount(), - queryBuilder.clone().andWhere("proof.status = :status", { status: "applied" }).getCount(), - queryBuilder.clone().andWhere("proof.status = :status", { status: "rejected" }).getCount(), - queryBuilder.clone().getCount() + repo.count({ where: { ...baseWhere, status: "pending" as L2PSProofStatus } }), + repo.count({ where: { ...baseWhere, status: "applied" as L2PSProofStatus } }), + repo.count({ where: { ...baseWhere, status: "rejected" as L2PSProofStatus } }), + repo.count({ where: baseWhere }) ]) return { pending, applied, rejected, total } }src/libs/l2ps/L2PSBatchAggregator.ts (2)
611-616: Inconsistent SharedState access pattern.Line 615 uses
SharedState.getInstance()directly while lines 340, 415, 432, and 452 use the importedgetSharedState. This inconsistency could cause confusion and potential issues if the access patterns differ.Use consistent access pattern throughout:
getStatus(): { // ... } { return { isRunning: this.isRunning, isAggregating: this.isAggregating, intervalMs: this.AGGREGATION_INTERVAL, - joinedL2PSCount: SharedState.getInstance().l2psJoinedUids?.length || 0, + joinedL2PSCount: getSharedState.l2psJoinedUids?.length || 0, } }
461-461: Public key type assumption may fail for non-Uint8Array keys.The code casts
sharedState.keypair.publicKey as Uint8Arraywithout runtime validation. If the key is stored in a different format (e.g., hex string), this will produce incorrect results.Add runtime type checking or use a normalized getter:
- const nodeIdentityHex = uint8ArrayToHex(sharedState.keypair.publicKey as Uint8Array) + let nodeIdentityHex: string + if (sharedState.keypair.publicKey instanceof Uint8Array) { + nodeIdentityHex = uint8ArrayToHex(sharedState.keypair.publicKey) + } else if (typeof sharedState.keypair.publicKey === 'string') { + nodeIdentityHex = sharedState.keypair.publicKey + } else { + log.error("[L2PS Batch Aggregator] Unsupported public key format") + return false + }src/libs/network/endpointHandlers.ts (3)
57-58: Tighten or remove temporarySubnetPayloadalias once real type existsRight now
SubnetPayload = anyis unused here and may confuse future readers. Once the proper export is available, either replace this alias with the real type where needed or drop it entirely if you keep relying onL2PSTransactioninstead.
330-377: Strengthen L2PS encrypted tx validation with better typing and sender checksThe new
l2psEncryptedTxcase correctly short‑circuits on malformed input and returns early on success so L2PS txs never hit the main mempool. A couple of refinements would make this path more robust:
- Use the existing
L2PSEncryptedPayload(or a dedicated interface) to typetx.content.data[1]instead of relying ontypeof l2psPayload === "object", and consider validating a few required fields.- Consider asserting that the derived
senderAddressmatches thesenderargument (or whatever canonical identity you use) so a peer cannot submit a tx on behalf of another identity just by settingfrom/from_ed25519_address.These are hardening suggestions; the current logic is functionally consistent with the surrounding flow.
814-898: Verifyblock_numberfield usage and align behavior with doc commentThe overall validation flow for
handleL2PSHashUpdatelooks solid (structure checks, required fields, guardingupdateHashwith try/catch), but there are a couple of points to double‑check:
- You gate on
tx.block_numberand passBigInt(tx.block_number)toL2PSHashes.updateHash, while other parts of this file useblockNumber. Please confirm thatTransactionfor this path indeed exposesblock_number(and is populated before this handler runs); otherwise this check will always fail and the update will be rejected.- The doc comment says “Validates that the sender is part of the L2PS network”, but the implementation only checks that this node has a local
l2psInstancefor the UID. If sender‑membership validation is required by the protocol, you may want to incorporate the sender identity and signature here, or adjust the comment to reflect the actual behavior.Neither blocks merging, but they’re worth verifying so L2PS hash updates behave as intended.

src/libs/network/routines/transactions/handleL2PS.ts (2)
137-170: Execution flow and status updates look correct.The execution flow properly uses
l2psTx.hash(the encrypted transaction hash) for mempool status updates, which correctly matches the hash stored in the mempool at line 124. Error handling appropriately logs and returns descriptive messages for both caught exceptions and failed execution results.
172-186: Response structure exposes detailed execution metadata.The response now includes comprehensive execution details (
proof_id,affected_accounts,message) which is useful for debugging and tracing. However, exposingaffected_accountsin the response could leak information about which accounts are involved in the L2PS transaction.Verify whether exposing
affected_accountsin the response aligns with L2PS privacy requirements. If L2PS is meant to provide privacy, this could inadvertently leak transaction participants.src/libs/l2ps/L2PSConsensus.ts (1)
302-329: L1 batch transaction uses empty signature data.The batch transaction at line 309 has an empty signature (
data: ""). While the comment says "System-generated, no actual signature needed", this could cause issues:
- Signature verification logic elsewhere may reject transactions with empty signatures
- No authentication that this transaction came from a legitimate consensus participant
Verify that downstream transaction handling (mempool, block inclusion, validation) accepts transactions with empty signature data, or consider signing with the node's key for authenticity.
src/libs/l2ps/L2PSTransactionExecutor.ts (3)
127-174: Switch cases properly scoped with block statements.The switch cases are now wrapped in blocks (
case "native": { ... }) as recommended in the past review. This prevents variable hoisting issues and TDZ problems.
240-297: Native transaction handling correctly validates amount type.The amount validation at lines 246-248 properly checks for
typeof amount !== 'number',!Number.isFinite(amount), andamount <= 0as recommended in the past review.
399-405: Update status now properly checks affected rows.The
updateTransactionStatusmethod now checksresult.affected === 0and logs a warning, addressing the past review concern about silent failures.src/libs/l2ps/L2PSProofManager.ts (2)
201-212:getProofsForBlockignoresblockNumberparameter - documented with TODO.The previous review noted this issue. The method now includes a TODO comment explaining that block-specific filtering will be implemented when block-specific batching is ready. This is acceptable as a known limitation.
The TODO at line 204-205 clearly documents the intent to filter by
target_block_numberin the future.
117-120: Deterministic hash generation now uses stable inputs.The
transactionsHashcomputation no longer includesDate.now(), addressing the past review concern. It now usesdeterministicStringifywith{ l2psUid, l1BatchHash, gcrEdits }which are all stable inputs.src/libs/l2ps/L2PSBatchAggregator.ts (2)
363-374: HMAC security properly enforced - no insecure fallback.The code now throws an error when
sharedState.keypair?.privateKeyis unavailable instead of falling back to the predictablebatchHash. This addresses the past review's critical security concern.
395-438: Nonce persistence only survives within process lifetime.The nonce is stored in
sharedState.l2psBatchNonce, which only persists during the current process lifetime. On service restart, the nonce resets to 0 and relies ontimestamp * 1000to avoid collisions. WhileMath.max(timestampNonce, lastNonce + 1)provides some protection, rapid restarts within the same millisecond could still cause issues.For production resilience, consider persisting the nonce to the database:
// Example: Store in a settings/config table private async getLastNonceFromStorage(): Promise<number> { const repo = await Datasource.getInstance() const ds = repo.getDataSource() // Query from a persistent settings table const setting = await ds.getRepository(Settings).findOne({ where: { key: 'l2ps_batch_nonce' } }) return setting?.value ? parseInt(setting.value, 10) : 0 }src/libs/peer/routines/getPeerIdentity.ts (2)
140-173: Excellent: Proper ed25519 signature verification now implemented.This addresses the previous review concern about incomplete signature verification. The function now:
- Uses proper cryptographic verification via
ucrypto.verifyinstead of heuristic checks- Implements domain separation (
"DEMOS_PEER_AUTH_V1") to prevent signature reuse across contexts- Correctly normalizes inputs by removing "0x" prefixes before verification
- Includes appropriate error handling
180-180: Verify that all calling code handles the nullable return type.The return type changed from
Promise<Peer>toPromise<Peer | null>. This is a breaking API change that requires all call sites to properly handle the null case. Ensure the codebase has been fully updated to check for null returns before this change is merged.src/libs/l2ps/parallelNetworks.ts (7)
108-133: Good implementation of promise locking to prevent race conditions.The pattern correctly handles concurrent load requests for the same UID by returning the existing promise, and properly cleans up in the
finallyblock.
141-169: Good defense-in-depth security practices.Path traversal protection via
startsWithcheck (lines 146-148) combined with UID validation (line 110) provides robust protection. The explicit validation ofnodeConfig.keysbefore property access (lines 167-169) prevents potential undefined access errors.
297-311: Verify: Missing signature allows decryption to proceed.Invalid signatures correctly throw an error (line 307), but missing signatures only log a warning while allowing decryption to continue. This asymmetry could allow unsigned transactions to bypass verification.
If missing signatures should be rejected, consider:
} else { - log.warning(`[L2PS] No signature found on encrypted transaction for ${uid}`) + throw new Error(`L2PS transaction missing required signature for ${uid}`) }If allowing unsigned transactions is intentional (e.g., for backwards compatibility), consider documenting this behavior in the method's JSDoc.
336-349: Good defensive validation before destructuring.The array length check (line 337) prevents potential runtime errors when destructuring, and the error handling provides useful debugging information.
181-187: LGTM - hex-based key loading is well structured.The flow properly reads hex strings, validates them via
hexFileToBytes, and passes the byte data toL2PS.create. The async/await pattern is correctly used.
226-251: Verify all logger methods exist.This segment uses
log.warning(line 230) andlog.info(line 244) in addition tolog.error. Ensure these methods are defined on the logger class.
396-402: Verifylog.debugmethod exists on the logger class.The logger utility snippet provided in context only shows
log.error(). Confirm thatlog.debug()is defined and accessible on the logger class, as its absence would cause a runtime error when processing L2PS transactions.src/libs/network/endpointHandlers.ts (2)
19-20: Type‑only import forL2PSTransactionis a clean improvementUsing
import type { L2PSTransaction }keeps the runtime bundle lean while preserving typing; the separation from the value import forTransactionlooks good.
126-132: GCREdit hashing refactor is fine and keeps semantics unchangedFactoring the JSON strings into
gcrEditsStringandtxGcrEditsStringbefore hashing preserves behavior while making logging/debugging easier; no issues from a correctness standpoint.

46-95: Identity normalization returns mixed hex formats (“0x…” vs bare hex) – unify to a single canonical formRight now:
normalizeIdentityreturns bare hex (no0xprefix) for all byte/typed-array/BufferPayloadcases (uint8ArrayToHex(...).toLowerCase()).- String and
IdentityEnvelope.publicKeycases go throughasHexString, returning0x-prefixed hex.normalizeExpectedIdentityalways returns0x-prefixed hex.This makes the equality check on Line 253 (
receivedIdentity === expectedIdentity) fail whenever the peer sends identity as bytes/arrays instead of a string, even if both represent the same key. This is the same functional risk flagged in the earlier review.A minimal fix is to make every non-string path in
normalizeIdentityreturn the same0x-prefixed canonical form by delegating toasHexString:@@ - if (raw instanceof Uint8Array) { - return uint8ArrayToHex(raw).toLowerCase() - } + if (raw instanceof Uint8Array) { + return asHexString(uint8ArrayToHex(raw)) // always "0x..." lowercased + } @@ - if (ArrayBuffer.isView(raw)) { - const bytes = - raw instanceof Uint8Array - ? raw - : new Uint8Array(raw.buffer, raw.byteOffset, raw.byteLength) - return uint8ArrayToHex(bytes).toLowerCase() - } + if (ArrayBuffer.isView(raw)) { + const bytes = + raw instanceof Uint8Array + ? raw + : new Uint8Array(raw.buffer, raw.byteOffset, raw.byteLength) + return asHexString(uint8ArrayToHex(bytes)) + } @@ - if (raw instanceof ArrayBuffer) { - return uint8ArrayToHex(new Uint8Array(raw)).toLowerCase() - } + if (raw instanceof ArrayBuffer) { + return asHexString(uint8ArrayToHex(new Uint8Array(raw))) + } @@ - if (Array.isArray(raw) && raw.every(item => typeof item === "number")) { - return uint8ArrayToHex(Uint8Array.from(raw)).toLowerCase() - } + if (Array.isArray(raw) && raw.every(item => typeof item === "number")) { + return asHexString(uint8ArrayToHex(Uint8Array.from(raw))) + } @@ - const maybeBuffer = raw as Partial<BufferPayload> - if (maybeBuffer?.type === "Buffer" && Array.isArray(maybeBuffer.data)) { - return uint8ArrayToHex( - Uint8Array.from(maybeBuffer.data), - ).toLowerCase() - } + const maybeBuffer = raw as Partial<BufferPayload> + if (maybeBuffer?.type === "Buffer" && Array.isArray(maybeBuffer.data)) { + return asHexString(uint8ArrayToHex(Uint8Array.from(maybeBuffer.data))) + }With this, both
receivedIdentityandexpectedIdentityare always"0x..."hex strings and comparisons, logging, and downstream usage are consistent.If you expect any non-hex payloads in these branches, we can instead prepend
"0x"manually and avoid re-validating withasHexString. Would you like help adjusting this to your exact payload shapes?Also applies to: 97-113
230-251: Challenge-response is still optional – spoofing risk remains (previously flagged)Even with proper ed25519 verification in place, peers that omit
challenge_signatureare still accepted after only logging a warning (Lines 245–251). This keeps backward compatibility but leaves an open path for identity spoofing by any peer that doesn’t implement the challenge flow. This is the same concern raised in the earlier review.If you’re ready to harden this, one strict version would be:
if (challengeSignature) { @@ console.log("[PEER AUTHENTICATION] Challenge-response verified successfully") } else { - // Log warning but allow connection for backward compatibility - console.warn( - "[PEER AUTHENTICATION] WARNING: Peer did not provide challenge signature - " + - "authentication is weaker without challenge-response verification", - ) + // Reject peers without challenge-response + console.log( + "[PEER AUTHENTICATION] No challenge signature provided - rejecting connection", + ) + return null }If you need a transition period, I’d recommend:
- Logging a clear deprecation notice when
challenge_signatureis missing.- Adding metrics so you can see how many peers will be impacted.
- Planning a staged rollout where non-compliant peers are eventually rejected.
🧹 Nitpick comments (3)
src/libs/network/endpointHandlers.ts (1)
350-358: Misleading comment: sender address is not verified against signature.The comment states "Verify sender address matches the transaction signature" but the code only checks for the presence of a sender address, not that it cryptographically matches the signature. The actual signature verification happens earlier (lines 238-258) against
validatedData.rpc_public_key, which may differ from the transaction'sfromaddress.If authorization requires that the signer is the sender, consider adding actual verification:
// Verify sender address matches the transaction signature - // This prevents unauthorized submission of L2PS transactions + // Ensure sender address is present (signature was already verified above) const senderAddress = tx.content?.from || tx.content?.from_ed25519_address if (!senderAddress) { log.error("[handleExecuteTransaction] L2PS tx rejected: missing sender address") result.success = false result.response = { error: "L2PS transaction requires sender address" } break } + + // Optional: verify signer matches sender if required + // if (validatedData.rpc_public_key.data !== senderAddress) { ... }src/libs/peer/routines/getPeerIdentity.ts (2)
115-121:verifyPeeralways returnspeereven if authentication fails – clarify or tighten the contract
getPeerIdentitycan now returnnullon any verification failure, butverifyPeerignores that and always returns the originalpeer. Callers that assumeawait verifyPeer(...)implies a verified identity may be misled if they don’t also checkpeer.verification.status.Consider one of these options:
- Propagate failure explicitly (safer, breaking change):
-export async function verifyPeer( - peer: Peer, - expectedKey: string, -): Promise<Peer> { - await getPeerIdentity(peer, expectedKey) - return peer -} +export async function verifyPeer( + peer: Peer, + expectedKey: string, +): Promise<Peer | null> { + return getPeerIdentity(peer, expectedKey) +}
- Keep signature but expose result clearly (non-breaking, but more implicit):
- Return a boolean (
trueif verified,falseotherwise) and let callers readpeerfrom their own scope.- Or, at minimum, document in code comments that callers must check
peer.verification.statusand/or the return value ofgetPeerIdentityrather than trusting the returnedpeer.I recommend auditing current call sites of
verifyPeerto ensure none are treating a successfulawaitas “peer is verified” without an additional check. If you’d like, I can help you write a script to locate and inspect those usages.
124-131: Overall challenge-based identity flow is well-structured; consider minor robustness/logging tweaksThe end-to-end flow—generate challenge → send via
NodeCall.data→ normalizeidentity/publicKey→ verify ed25519 signature → compare with normalized expected key → updatepeerstate—is coherent and a big improvement security-wise.A few minor, optional refinements you might consider later:
- Reduce raw logging of sensitive objects (
peer, fullresponse) in production, or route through your structured logger with log levels and redaction for keys/signatures.- Include the normalized identity (shortened) in
peer.verification.messagealongside the truncated challenge to aid debugging multiple peers with similar keys.- Guard against malformed
response.responsetypes by defaultingresponseDatato{}and maybe logging its type when normalization fails, to make operational debugging easier.No blockers here; these are polish items.

19-19: LGTM!Using
import typeforTransactionandL2PSTransactionis the correct pattern since these are only used for type annotations and type assertions, not runtime operations.
123-128: LGTM!The refactor to use intermediate string variables improves readability and aids debugging while maintaining the same functional behavior.
327-374: Block scope correctly applied.The switch case is now properly wrapped in a block
{ }withconst l2psResult, addressing the previous scope leakage concern. The early return pattern cleanly prevents L2PS transactions from being added to the main mempool.src/libs/peer/routines/getPeerIdentity.ts (1)
132-172: Ed25519 challenge verification logic looks correct; confirm ucrypto and TextEncoder behavior in your target runtime
verifyChallengenow:
- Builds a domain-separated message (
"DEMOS_PEER_AUTH_V1:<challenge>").- Strips optional
0xfrompublicKeyandsignature.- Uses
ucrypto.verify({ algorithm: "ed25519", message, publicKey, signature })withhexToUint8Arrayconversions.This is a solid upgrade over the previous heuristic and matches typical ed25519 verification patterns. I don’t see functional issues in this block as written.
Please double-check against your actual runtime and SDK version that:
ucrypto.verifyexpects aUint8Arraymessage and key/signature in the way you’re passing them.TextEncoderis available in your Node target (or polyfilled via TS lib settings).If you want, I can help you draft a small integration test that signs and verifies a known message with a test keypair to lock this in.

117-152: Deterministic proof hashing and verification look consistent.Using
deterministicStringifyboth when constructingtransactionsHashand the placeholder proof (data) increateProof, and again when recomputing the expected hash inverifyProof, gives you stable, JSONB‑robust hashes and removes the previousDate.now()non‑determinism.

getProofswith an empty UID and to give consensus a precise way to fetch proofs by block, add a dedicated helper with the suggested implementation.The pattern is sound: creating a specialized query method (
getAppliedProofsForBlock) that encapsulates the specific filtering logic by block and applied status prevents misuse of the genericgetProofsmethod, which requires a UID parameter. This is good API design.Ensure the implementation aligns with:
- The L2PSProof entity schema (verify
applied_block_numberfield exists)- The intended usage in
L2PSConsensus.rollbackProofsForBlockandgetBlockStatsmethods- Query performance expectations (ordering by

Include nonce edits in the account-required validation.
The comment states “Balance and nonce edits require account field”, but the guard only enforces this for balance edits. As written, a malformed nonce edit without account would pass structural validation.
You can tighten this with:
- // Validate each GCR edit has required fields
- for (const edit of proof.gcr_edits) {
- // Balance and nonce edits require account field
- if (!edit.type || (edit.type === 'balance' && !('account' in edit))) {
- log.warning(`[L2PS ProofManager] Proof ${proof.id} has invalid GCR edit`)
- return false
- }
- }

In src/libs/l2ps/L2PSProofManager.ts around lines 233 to 240, the validation
only requires the account field for edits of type 'balance' but the comment says
both 'balance' and 'nonce' need an account; update the guard to also treat
edit.type === 'nonce' as requiring 'account' (i.e., check if edit.type is
'balance' or 'nonce' and that 'account' is present), leave the warning and
return false behavior intact so malformed nonce edits are rejected the same way
as balance edits.

""does not mean “all networks”; it filters forl2ps_uid === "". Unless you actually have an L2PS network with an empty UID, both methods will see zero proofs:
- No proofs rolled back when a block fails.
- Block stats always report zero applied proofs/edits.
Please switch to a helper that explicitly means “all applied proofs for a given block”, e.g.:
const proofsToRollback = await L2PSProofManager.getAppliedProofsForBlock(blockNumber, 1000)and likewise in
getBlockStats:const blockProofs = await L2PSProofManager.getAppliedProofsForBlock(blockNumber, 10000)(or whatever helper you’ve implemented on

getNextBatchNoncederives nonces fromDate.now() * 1000and a value cached insharedState.l2psBatchNonce. This gives a monotonic sequence within a process and across restarts as long as the system clock is monotonic, but it does not persist across process restarts (no DB/FS write).To avoid confusion for future maintainers, I’d tighten the comments:
- Emphasize that persistence is per-process (via shared state), not durable.
- Note that uniqueness across restarts is time-based, not strictly persisted.

Also,
simulatedoes not affect any behaviour (we always hit the DB and build edits).Not strictly wrong, but you might want to harden this:
if (!Array.isArray(tx.content.data) || tx.content.data[0] !== "native") { return { success: false, message: "Invalid native payload structure" } } const [, nativePayload] = tx.content.data as ["native", INativePayload]and optionally gate side effects in simulate mode if that’s part of your design contract.
Pure robustness / clarity; current path is logically correct for well-formed inputs.

execute reports “Proof created” even when no proof is created (zero-edit case)
When gcrEdits.length === 0, the if (!simulate && gcrEdits.length > 0) branch is skipped, so no proof is created or recorded. However the fallback success path still says:
message: simulate
? `Validated: ${gcrEdits.length} GCR edits would be generated`
: `Proof created with ${gcrEdits.length} GCR edits (will apply at consensus)`For zero edits this reports “Proof created with 0 GCR edits” even though no proof exists, which can confuse callers and operators.
Consider distinguishing the “no edits / no proof” case:
- return {
- success: true,
- message: simulate
- ? `Validated: ${gcrEdits.length} GCR edits would be generated`
- : `Proof created with ${gcrEdits.length} GCR edits (will apply at consensus)`,
- gcr_edits: gcrEdits,
- affected_accounts: [...new Set(affectedAccounts)]
- }
+ const base = {
+ success: true,
+ gcr_edits: gcrEdits,
+ affected_accounts: [...new Set(affectedAccounts)],
+ }
+
+ if (simulate) {

+ message: `Validated: ${gcrEdits.length} GCR edits would be generated`,

+ ...base,
+ message: gcrEdits.length === 0
+ ? "No GCR edits generated; transaction recorded without proof"
+ : `Proof created with ${gcrEdits.length} GCR edits (will apply at consensus)`,
+ }This keeps semantics and observability aligned.

In src/libs/l2ps/L2PSTransactionExecutor.ts around lines 113 to 144, the success
fallback message incorrectly claims a proof was created when gcrEdits.length ===
0; change the logic so when not simulating and gcrEdits.length === 0 you return
a success result that explicitly states no GCR edits were generated and that no
proof was created/recorded, and preserve the existing proof-created message only
when a proof was actually created; keep gcr_edits as an empty array and ensure
affected_accounts is deduplicated in the returned result.

51-102: Verify @solana/web3.js version explicitly due to recent supply-chain incident.The new dependencies appropriately support the ZK-SNARK infrastructure (
snarkjs0.7.5,circomlib2.0.5,circomlibjs0.1.7), Solana/Anchor integrations, and security hardening (helmet8.1.0). However, @solana/web3.js experienced a supply-chain attack in December 2024 (CVE-2024-54134) affecting versions 1.95.6–1.95.7. The pinned version 1.98.4 is post-patch and should be safe, but confirm this version is intentional and monitor for any subsequent releases. Additionally, ensure snarkjs remains at ≥0.7.0 to maintain the fix for CVE-2023-33252, and keep circomlib updated as maintenance activity is limited.

26-27: Unusedchecksignal - clarify intent or remove.The
checksignal computessender_after * sender_afterbut is never used in any constraint. If the intent is to enforce non-negative balances, note that squaring in a finite field doesn't prevent underflow—negative values (large field elements) still produce valid squares.If this is intentional for future use or as a constraint-generation placeholder, consider adding a comment. Otherwise, remove it.
- signal check; - check <== sender_after * sender_after; + // Note: Non-negativity is enforced off-chain before proof generationsrc/libs/l2ps/zk/snarkjs.d.ts (1)
1-78: LGTM - Minimal but functional type declarations for snarkjs.The type declarations provide adequate coverage for PLONK/Groth16 proof generation and verification workflows. Using
anyfor proof objects is pragmatic given snarkjs's dynamic nature.src/libs/network/routines/transactions/handleL2PS.ts (3)
12-20: LGTM - Clean error response helper.The
createErrorResponsehelper centralizes error formatting, improving code consistency.
129-145: Execution flow and status updates look correct.The execution delegates to
L2PSTransactionExecutor, properly handles errors with logging, and updates mempool status appropriately (failedon error,executedon success).
70-70: Double cast is necessary for type conversion between SDK and local Transaction classes, not a type safety bypass.The cast converts from the SDK's
Transactiontype (returned byl2psInstance.decryptTx()) to the localTransactionclass required by the function's return type. The localTransactionclass implements the SDK'sITransactioninterface, and the object passes validation viaTransaction.confirmTx()before the cast, ensuring structural correctness at runtime.src/libs/l2ps/zk/circuits/l2ps_batch_5.circom (1)
23-24: Consider adding balance underflow protection.The constraint
sender_after === sender_before - amountoperates in a finite field where underflow wraps around rather than failing. A malicious prover could create a valid proof withsender_before < amountresulting in a wrapped value.If balance validity must be enforced on-chain, add a range check or ensure the off-chain prover validates
sender_before >= amountbefore proof generation.src/libs/l2ps/zk/L2PSBatchProver.ts (1)
215-278: LGTM - proof generation flow is well-structured.The
generateProofmethod properly:
- Ensures initialization before use
- Validates input (empty batch check)
- Selects appropriate batch size
- Pads transactions correctly
- Uses
singleThreadoption for Bun compatibilitysrc/libs/l2ps/zk/BunPlonkWrapper.ts (2)
86-187: LGTM - Bun-compatible PLONK verification is well-implemented.The implementation:
- Correctly uses
singleThread: trueto avoid Bun worker crashes- Properly terminates the curve in
finallyblock to prevent memory leaks- Returns
falseon errors rather than throwing, which is appropriate for verification- Follows the snarkjs reference implementation faithfully
29-78: LGTM - Keccak256Transcript correctly implements Fiat-Shamir.The transcript class properly handles polynomial commitments and scalars for challenge derivation, matching the snarkjs reference implementation.
src/libs/l2ps/L2PSBatchAggregator.ts (4)
663-669: LGTM - Cycle time calculation is correct.The
updateCycleTimemethod is only called aftersuccessfulCyclesis incremented (line 248), so division by zero cannot occur. The running average formula correctly handles the first cycle case.
444-456: ZK proof uses placeholder data - proofs won't verify actual balances.The TODO at line 447 notes this, but it's worth emphasizing: the current implementation derives balance values from transaction hashes rather than actual amounts. This means:
- ZK proofs will be mathematically valid but semantically meaningless
- Balance underflows/overflows won't be caught
- The proof only demonstrates circuit execution, not transaction validity
Until actual transaction amounts are extracted, consider either:
- Disabling ZK proofs entirely (
zkEnabled = false)- Clearly logging that proofs are in "placeholder mode"
397-410: LGTM - HMAC key handling now fails fast as recommended.The code now throws an error when
keypair.privateKeyis unavailable instead of using an insecurebatchHashfallback. This addresses the security concern from the previous review.
514-526: Nonce persistence is process-lifetime only - consider database storage for production.The current implementation persists nonces in
sharedState, which survives within the same process but resets on restart. The timestamp-based fallback (line 500-503) provides reasonable collision resistance, but for production deployments with strict ordering requirements, consider persisting to the database.The current approach is acceptable for development/testing.
src/libs/l2ps/L2PSProofManager.ts (5)
34-44: LGTM! Deterministic stringify implementation is solid.The alphabetical key sorting ensures consistent hashing across JSONB round-trips, and arrays are correctly left in their original order.
111-171: LGTM! Proof creation uses deterministic hashing.The previous concern about non-deterministic
Date.now()timestamps has been resolved. The implementation now usesdeterministicStringifyconsistently for stable hash generation.
194-211: LGTM! Reserved parameter for future block-specific filtering.The
blockNumberparameter is intentionally unused with a clearFUTUREcomment. This reserves the API signature for block-specific batching without requiring breaking changes later.
258-292: LGTM! Status update methods are correctly implemented.Both
markProofAppliedandmarkProofRejectedproperly update proof status with appropriate metadata (block number, error message, timestamps).
332-356: LGTM! Statistics query uses proper QueryBuilder cloning.The
clone()pattern correctly creates independent queries for each status count, andPromise.allefficiently executes them in parallel.src/model/entities/L2PSProofs.ts (3)
38-44: LGTM! Index definitions are correct and comprehensive.All index names follow a consistent naming convention, and the compound index on
[l2ps_uid, status]will optimize common query patterns.
85-97: LGTM! Proof structure is well-defined and flexible.The JSONB column supports multiple proof systems (hash, plonk, snark, stark) with comprehensive metadata fields for production use.
99-167: LGTM! Column definitions are appropriate and well-documented.All columns have correct types, nullability, and defaults. The use of
simple-arrayforaffected_accountsis suitable for a string array.src/libs/l2ps/L2PSTransactionExecutor.ts (7)
49-77: LGTM! Repository initialization uses proper promise guard pattern.The lazy initialization with
initPromiseguard prevents race conditions when multiple calls occur before initialization completes.
154-186: LGTM! GCR edit generation logic is clear and handles all cases.The method properly delegates to
handleNativeTransactionfor native transactions and validates providedgcr_editsfor other types.
226-296: LGTM! Native transaction handling includes proper validation.The amount validation checks type, finiteness, and ensures positive values. Variables are properly scoped within the if/else blocks.
298-333: LGTM! GCR edit validation is properly scoped.All switch cases are wrapped in braces, and the unused
repovariable issue from past reviews has been resolved.
335-370: LGTM! Transaction recording handles BigInt conversions correctly.The method properly converts
amount,nonce, andtimestamptoBigInttypes as required by the entity schema.
372-396: LGTM! Status update now detects when no rows match.The method checks
result.affected === 0and logs a warning, preventing silent failures when updating non-existent transaction hashes.
398-484: LGTM! Query methods provide comprehensive L2PS data access.The account transaction query correctly uses an array of where conditions to match both sender and receiver addresses. Statistics properly combine transaction and proof data.

191-193: Inconsistent null handling:getTransactionFromHashmay throw on null input.Unlike the established pattern in
getTxByHash(lines 76-92), this method callsTransaction.fromRawTransactiondirectly without checking if the repository returned null. IffindOneByreturns null,fromRawTransactionwill throw an error due to the defensive check at line 499 intransaction.ts.Update the method to align with the
getTxByHashpattern:static async getTransactionFromHash(hash: string): Promise<Transaction | null> { + const rawTx = await this.transactions.findOneBy({ hash: ILike(hash) }) + + if (!rawTx) { + return null + } + - return Transaction.fromRawTransaction( - await this.transactions.findOneBy({ hash: ILike(hash) }), - ) + return Transaction.fromRawTransaction(rawTx) }This requires:
- Updating the return type from
Promise<Transaction>toPromise<Transaction | null>- Adding null check before calling
fromRawTransaction- Updating the call site in
src/libs/blockchain/routines/subOperations.ts(line 38) to handle null returns

736-748: Critical:getSharedStatemust be called as a function.On line 746,
getSharedStateis not invoked. This will fail at runtime when attempting to access the.l2psJoinedUidsproperty on the function itself rather than the state object.This issue was flagged in past review comments but remains unresolved.
Based on learnings, past review comment from coderabbitai flagged this exact issue. Apply this diff:
getStatus(): { isRunning: boolean; isAggregating: boolean; intervalMs: number; joinedL2PSCount: number; } { + const sharedState = getSharedState() return { isRunning: this.isRunning, isAggregating: this.isAggregating, intervalMs: this.AGGREGATION_INTERVAL, - joinedL2PSCount: getSharedState.l2psJoinedUids?.length || 0, + joinedL2PSCount: sharedState.l2psJoinedUids?.length || 0, } }
638-638: Set meaningfulreference_blockvalue.The comment states "Will be set by mempool" but according to past reviews, the mempool implementation passes
reference_blockthrough to persistence without recalculating it. Storing0may bypass anchoring/ordering semantics.Consider setting a meaningful reference block:
- reference_block: 0, // Will be set by mempool + reference_block: sharedState.lastKnownBlock || 0, // Anchor to current block heightIf
lastKnownBlockis not available in SharedState, query the latest block height from the blockchain state before constructing this transaction, or document why0is intentionally correct for batch transactions.Based on learnings, past review comment from coderabbitai indicates this needs to be set to a proper value.

src/libs/l2ps/L2PSBatchAggregator.ts (3)
93-94: Remove unusedbatchNonceCounterproperty.This property is declared but never used in the implementation. The actual nonce management correctly uses
getLastNonceFromStorage()andsaveNonceToStorage()methods. This dead code should be removed to avoid confusion.Apply this diff:
- /** Persistent nonce counter for batch transactions */ - private readonly batchNonceCounter: number = 0
399-410: Add runtime type guard forprivateKey.The code assumes
sharedState.keypair.privateKeyis aUint8Arraywithout verification. If the actual type is a string or another format, theBuffer.from()cast will fail or produce incorrect results.Apply this diff to add a type check:
if (!sharedState.keypair?.privateKey) { throw new Error("[L2PS Batch Aggregator] Node keypair not available for HMAC generation") } - const hmacKey = Buffer.from(sharedState.keypair.privateKey as Uint8Array) + const privateKey = sharedState.keypair.privateKey + if (!(privateKey instanceof Uint8Array)) { + throw new Error("[L2PS Batch Aggregator] Node private key must be Uint8Array format") + } + + const hmacKey = Buffer.from(privateKey) .toString("hex") .slice(0, 64)
586-592: Add runtime type guard forpublicKey.The code assumes
sharedState.keypair.publicKeyis aUint8Arraywithout verification. IfsharedState.publicKeyHexis already available and normalized, prefer reusing it. Otherwise, add a type check.Based on learnings, past reviews flagged this assumption. Apply one of these approaches:
Option 1 (preferred if
publicKeyHexis available):- // Get node's public key as hex string for 'from' field - const nodeIdentityHex = uint8ArrayToHex(sharedState.keypair.publicKey as Uint8Array) + // Get node's public key as hex string for 'from' field + const nodeIdentityHex = sharedState.publicKeyHex + if (!nodeIdentityHex) { + log.error("[L2PS Batch Aggregator] Node public key hex not available") + return false + }Option 2 (if publicKeyHex is not available):
- // Get node's public key as hex string for 'from' field - const nodeIdentityHex = uint8ArrayToHex(sharedState.keypair.publicKey as Uint8Array) + // Get node's public key as hex string for 'from' field + const publicKey = sharedState.keypair.publicKey + if (!(publicKey instanceof Uint8Array)) { + log.error("[L2PS Batch Aggregator] Node public key must be Uint8Array format") + return false + } + const nodeIdentityHex = uint8ArrayToHex(publicKey)

372-424: Critical:getSharedStateisn’t invoked;sharedState.keypairwill crash.
This is the same “must callgetSharedState()” issue as prior reviews.Also: current HMAC key usage passes a hex string to
createHmac, which uses UTF-8 bytes of that string (likely unintended). Prefer aBufferkey.- const sharedState = getSharedState + const sharedState = getSharedState() + if (!sharedState) { + throw new Error("[L2PS Batch Aggregator] Shared state unavailable") + } ... - const hmacKey = Buffer.from(sharedState.keypair.privateKey as Uint8Array) - .toString("hex") - .slice(0, 64) + const hmacKey = Buffer.from(sharedState.keypair.privateKey as Uint8Array) const hmacData = `${l2psUid}:${encryptedBatch}:${batchHash}:${transactionHashes.join(",")}` const authenticationTag = crypto .createHmac("sha256", hmacKey) .update(hmacData) .digest("hex")

This is the same “must callgetSharedState()” issue as prior reviews.Also, two previously-raised robustness concerns still apply here:
