7-10: Interface name inconsistency in documentationThe NatSpec comment uses
IDistributionwhile the actual interface is namedIL2Distribution. This inconsistency should be resolved for clarity.-/** - * @title IDistribution - * @notice Interface for distributing rewards. - */ +/** + * @title IL2Distribution + * @notice Interface for distributing rewards. + */
22-22: Consider adding an interface-level error for unauthorized accessThe comment
/* onlyPayerContract */indicates an access restriction, but there's no corresponding error defined for when this restriction is violated. Consider adding custom errors to the interface.+ /// @notice Error thrown when a caller is not authorized to call a function. + error Unauthorized(); + function distributeRewards() external; /* onlyPayerContract */

283-312: FunctionMAXBPSfollows correct GoEthereum binding patterns.This new function provides access to the contract's maximum basis points value, which is essential for percentage-based calculations. The implementation correctly follows the standard GoEthereum binding patterns with proper error handling and type conversions.
3288-3420: Properly implemented event binding forMaxActiveNodesUpdated.The new
MaxActiveNodesUpdatedevent binding is correctly implemented with appropriate iterator, filter, watch, and parse methods following the established pattern for GoEthereum event bindings. This event will be important for tracking changes to the maximum number of active nodes in the system.
1241-1270:✅ Verification successful
Verify external interface support in
supportsInterfaceimplementation.Although the code for this function appears properly structured, ensure that the underlying Solidity implementation correctly supports the
INodesinterface as mentioned in the PR objectives. The binding itself doesn't reveal the changes to interface support.
🏁 Script executed:
#!/bin/bash # Check the supportsInterface implementation in the Solidity contract grep -A 10 "function supportsInterface" contracts/src/Nodes.solLength of output: 472
Interface support verified – no changes required.
The Solidity implementation in
contracts/src/Nodes.solcorrectly checks for theINodesinterface usingtype(INodes).interfaceIdand properly falls back to the parent implementation viasuper.supportsInterface(interfaceId). The Go binding inNodes.goleverages this implementation accurately. No further modifications are needed based on the review comment.contracts/src/Nodes.sol (1)
367-374: Update correctly implements ERC-165 interface detectionThe modification to the
supportsInterfacefunction properly declares support for theINodesinterface, enhancing compliance with the ERC-165 standard. This is a good improvement that allows other contracts to verify interface compatibility.contracts/src/interfaces/IL2Distribution.sol (1)
1-103: Well-structured interface with complete functionalityThe interface provides a comprehensive set of functions for managing reward distribution, with clear separation between distribution logic, administrative functions, and getters. The NatSpec documentation is thorough and explains the purpose of each function clearly.

4-19: Improved import organizationThe import statements have been nicely reorganized for better readability, with external imports grouped before internal imports and alphabetically ordered within groups.
289-296: Consistent variable naming convention appliedThe renamed local variable with underscore prefix (
_withdrawal) follows the new naming convention mentioned in the PR objectives, improving code consistency.
307-321: Consistent local variable renamingVariables have been renamed with underscore prefixes to follow the new convention for temporary variables.
348-392: Improved variable naming for clarityThe renaming of
feesto_feesaligns with the new naming convention while maintaining code functionality.
869-883: Enhanced contract validation with interface checksThe implementation now properly verifies that the new distribution contract supports the
IL2Distributioninterface using ERC-165 mechanism, which is a good security practice.
889-903: Parameter naming consistency improvementThe parameter
_newPayerReportContracthas been renamed tonewPayerReportContractto follow the convention where function parameters don't have prefixes.
909-921: Parameter naming consistency improvementThe parameter
_newNodesContracthas been renamed tonewNodesContractto follow the convention where function parameters don't have prefixes.
927-939: Parameter naming consistency improvementThe parameter
_newUsdcTokenhas been renamed tonewUsdcTokento follow the convention where function parameters don't have prefixes.
1022-1034: Added ERC-165 interface support for IPayerThe addition of the
supportsInterfacefunction enables other contracts to detect that this contract implements theIPayerinterface, improving interoperability. This matches the similar implementation in the Nodes contract.
