60-66: Add NatSpec documentation for the makeMessageHash function.The function would benefit from detailed documentation explaining:
- The purpose and use case of the message hash
- The exact hash computation method
- How it relates to quote validation
- Parameter requirements and constraints
Add NatSpec documentation above the function:
+ /// @notice Computes a message hash for quote validation + /// @param _chainName The name of the chain + /// @param _tokenName The name of the token + /// @param _fee The fee amount + /// @param _gasLimit The gas limit + /// @param _expiry The expiration timestamp + /// @return bytes32 The computed message hash function makeMessageHash( string memory _chainName, string memory _tokenName, uint256 _fee, uint256 _gasLimit, uint256 _expiry ) external pure returns (bytes32);
60-66: Consider adding parameter validation requirements.The interface should specify any validation requirements for the parameters (e.g., non-empty strings, minimum/maximum values for numeric fields).
Consider adding:
- A view function to get minimum/maximum bounds for fee and gasLimit
- Documentation specifying format requirements for chainName and tokenName
- Requirements for the expiry timestamp (e.g., minimum future window)

60-66: Verify integration with quote validation flow.
The function parameters match fields in the QuoteInput struct, suggesting it's used for signature verification. Let's verify this integration.
✅ Verification successful
Integration with quote validation flow is properly implemented
The makeMessageHash function is correctly integrated into the signature verification flow:
- The
quotefunction processes quote inputs and callsverifySignature - Inside
verifySignature:makeMessageHashis used to generate the message hash from input parameters- The signature is verified using ECDSA recovery to ensure it matches the oracle's address
- Failed verification reverts with
VerifySignatureFailed

63-63: LGTM! ABI updated correctly for the new makeMessageHash function.
The ABI addition properly defines the function signature with correct parameter types and return value.
336-365: LGTM! MakeMessageHash bindings implemented correctly.
The implementation follows the standard Go binding patterns with proper:
- Error handling
- Type conversions
- Documentation
- Pure function semantics
Let's verify the function signature matches the Solidity interface:
✅ Verification successful
Verified: MakeMessageHash implementation is correct
The Go bindings match the Solidity contract implementation perfectly:
- Function signature matches exactly including parameter names and types
- Pure function modifier is preserved
- Return type (bytes32) is correctly mapped to [32]byte in Go
- Implementation in Solidity uses keccak256(abi.encode()) which is correctly handled by the Go ABI encoding
