# Account Abstraction Tx Type Complete updated spec here: tempoxyz/docs#49 **Note:** 1. 2D nonces have been disabled at the validation level for the current PR. Because it requires some higher complexity changes to the tx pool. 2. Authorization lists have been skipped in the current TxAA type, because we require a new type of 7702 Auth item, which can take in signatures from passkeys/P256 keys. This will be added in a separate PR. ## Abstract This spec introduces native protocol support for the following account abstraction features, using a new account abstraction tx type - * WebAuthn/P256 signature validation - enables passkey accounts * Parallelizable nonces - allows higher tx throughput for each account * Gas sponsorship - allows apps to pay for their users's transactions * Call Batching - allows users to multicall cheaply. * Scheduled Txs - allow users to specify a time window in which their tx can be executed ### Transaction Type A new EIP-2718 transaction type is introduced with the following structure: ```rust pub struct TxAA { // Standard EIP-1559 fields chain_id: U64, max_priority_fee_per_gas: U256, max_fee_per_gas: U256, gas_limit: U64, calls: Vec<Call>, // Batch of calls to execute access_list: Vec<AccessListItem>, // AA-specific fields nonce_key: U64, // 64 bit sequence keys (was U192, changed to U64 for simplicity) nonce: U64, // 64 bit current value of the sequence key // Optional features fee_token: Option<Address>, // Optional fee token preference fee_payer_signature: Option<Bytes>, // Sponsored transactions (secp256k1 only) valid_before: U64, // Transaction expiration timestamp (0 means no expiry) valid_after: Option<U64> // Transaction can only be included after this timestamp } // Call structure for batching pub struct Call { to: TxKind, // Can be Address or Create value: U256, input: Bytes // Calldata for the call } ``` ### Signature Types Three signature schemes are supported, identified by length: #### secp256k1 (65 bytes) ```rust type K1Sig = { r: bytes32, s: bytes32, v: uint8 } ``` #### P256 (129 bytes) ```rust type P256Sig = { r: bytes32, s: bytes32, pubKeyX: bytes32, pubKeyY: bytes32, preHash: bool } ``` Note: Some p256 implementers like Web Crypto, require the digests to be prehashed before verification. If this bool is set to `true`, then before verification `bytes32 digest = sha256(digest)` needs to be performed. #### WebAuthn (Variable length, max 2KB) ```rust type WebAuthnSig = { verificationData: bytes, // Variable length r: bytes32, s: bytes32, pubKeyX: bytes32, pubKeyY: bytes32 } ``` ### Address Derivation #### secp256k1 ```solidity address(uint160(uint256(keccak256(abi.encode(x, y))))) ``` #### P256 and WebAuthn ```solidity function deriveAddressFromP256(bytes32 pubKeyX, bytes32 pubKeyY) public pure returns (address) { // Hash bytes32 hash = keccak256(abi.encodePacked( pubKeyX, pubKeyY )); // Take last 20 bytes as address return address(uint160(uint256(hash))); } ``` --------- Co-authored-by: Arsenii Kulikov <klkvrr@gmail.com> Co-authored-by: jxom <7336481+jxom@users.noreply.github.com> Co-authored-by: rakita <rakita@users.noreply.github.com>

# Account Abstraction Tx Type Complete updated spec here: tempoxyz/docs#49 **Note:** 1. 2D nonces have been disabled at the validation level for the current PR. Because it requires some higher complexity changes to the tx pool. 2. Authorization lists have been skipped in the current TxAA type, because we require a new type of 7702 Auth item, which can take in signatures from passkeys/P256 keys. This will be added in a separate PR. ## Abstract This spec introduces native protocol support for the following account abstraction features, using a new account abstraction tx type - * WebAuthn/P256 signature validation - enables passkey accounts * Parallelizable nonces - allows higher tx throughput for each account * Gas sponsorship - allows apps to pay for their users's transactions * Call Batching - allows users to multicall cheaply. * Scheduled Txs - allow users to specify a time window in which their tx can be executed ### Transaction Type A new EIP-2718 transaction type is introduced with the following structure: ```rust pub struct TxAA { // Standard EIP-1559 fields chain_id: U64, max_priority_fee_per_gas: U256, max_fee_per_gas: U256, gas_limit: U64, calls: Vec<Call>, // Batch of calls to execute access_list: Vec<AccessListItem>, // AA-specific fields nonce_key: U64, // 64 bit sequence keys (was U192, changed to U64 for simplicity) nonce: U64, // 64 bit current value of the sequence key // Optional features fee_token: Option<Address>, // Optional fee token preference fee_payer_signature: Option<Bytes>, // Sponsored transactions (secp256k1 only) valid_before: U64, // Transaction expiration timestamp (0 means no expiry) valid_after: Option<U64> // Transaction can only be included after this timestamp } // Call structure for batching pub struct Call { to: TxKind, // Can be Address or Create value: U256, input: Bytes // Calldata for the call } ``` ### Signature Types Three signature schemes are supported, identified by length: #### secp256k1 (65 bytes) ```rust type K1Sig = { r: bytes32, s: bytes32, v: uint8 } ``` #### P256 (129 bytes) ```rust type P256Sig = { r: bytes32, s: bytes32, pubKeyX: bytes32, pubKeyY: bytes32, preHash: bool } ``` Note: Some p256 implementers like Web Crypto, require the digests to be prehashed before verification. If this bool is set to `true`, then before verification `bytes32 digest = sha256(digest)` needs to be performed. #### WebAuthn (Variable length, max 2KB) ```rust type WebAuthnSig = { verificationData: bytes, // Variable length r: bytes32, s: bytes32, pubKeyX: bytes32, pubKeyY: bytes32 } ``` ### Address Derivation #### secp256k1 ```solidity address(uint160(uint256(keccak256(abi.encode(x, y))))) ``` #### P256 and WebAuthn ```solidity function deriveAddressFromP256(bytes32 pubKeyX, bytes32 pubKeyY) public pure returns (address) { // Hash bytes32 hash = keccak256(abi.encodePacked( pubKeyX, pubKeyY )); // Take last 20 bytes as address return address(uint160(uint256(hash))); } ``` --------- Co-authored-by: Arsenii Kulikov <klkvrr@gmail.com> Co-authored-by: jxom <7336481+jxom@users.noreply.github.com> Co-authored-by: rakita <rakita@users.noreply.github.com>
