src/concrete/VerifyAlwaysApproved.sol (4)
1-4: LGTM! Proper file headers and pragma version.The license, copyright, and pragma declarations are correctly formatted and use an appropriate Solidity version.
5-5: LGTM! Proper import statement.The import correctly brings in the required interface and constants.
7-12: LGTM! Excellent documentation and contract declaration.The NatSpec documentation clearly explains the contract's purpose as a no-op verifier, and the contract properly implements the
IVerifyV1interface.
13-18: LGTM! Correct function implementation.The function implementation is correct:
- Uses unnamed parameters since they're not used (good practice)
- Marked as
puresince it doesn't read state- Marked as
externalfor interface compliance- Always returns the expected constant value
- Includes proper documentation with
@inheritdoc.gas-snapshot (1)
1-1: LGTM! Reasonable gas usage for a simple function.The gas snapshot shows consistent usage (66,486 units) across 256 runs, which is expected for a simple
purefunction that returns a constant value.test/src/concrete/VerifyAlwaysApproved.accountStatusAtTime.t.sol (1)
1-9: LGTM! Proper test setup and imports.The test file has correct license headers, imports the necessary testing framework and contracts, and properly imports the required types.

🧹 Nitpick (assertive)
LGTM! Good test coverage with a minor optimization opportunity.
The test effectively uses property-based testing with fuzzed inputs to verify the contract always returns the expected status. The assertion logic is correct and includes a helpful error message.
Consider optimizing by using a shared contract instance:
contract VerifyAlwaysApprovedAccountStatusAtTimeTest is Test {
+ VerifyAlwaysApproved verifyAlwaysApproved;
+
+ function setUp() external {
+ verifyAlwaysApproved = new VerifyAlwaysApproved();
+ }
+
function testAccountStatusAtTime(address account, uint256 timestamp) external {
- VerifyAlwaysApproved verifyAlwaysApproved = new VerifyAlwaysApproved();
-
VerifyStatus status = verifyAlwaysApproved.accountStatusAtTime(account, timestamp);
assertEq(
VerifyStatus.unwrap(status),
VerifyStatus.unwrap(VERIFY_STATUS_APPROVED),
"VerifyAlwaysApproved.accountStatusAtTime should always return VERIFY_STATUS_APPROVED"
);
}
}This would reduce gas costs and improve test efficiency by reusing the same contract instance.

In test/src/concrete/VerifyAlwaysApproved.accountStatusAtTime.t.sol around lines
10 to 21, the test creates a new VerifyAlwaysApproved contract instance inside
the test function for each call, which is inefficient. To optimize, declare a
single VerifyAlwaysApproved contract instance as a state variable initialized
once before running tests, and reuse this instance in the
testAccountStatusAtTime function to reduce gas costs and improve test
efficiency.
