34-35: Metadata Update ApprovedThe updated ABI and binary data in
CrossChainTestMetaDataare aligned with the changes described in the PR summary. This ensures that the contract interactions are up-to-date with the latest contract definitions.
206-234: Correct Implementation of CROSSCHAINADDRESS MethodThe
CROSSCHAINADDRESSmethod is correctly implemented across different session types (CrossChainTestCaller,CrossChainTestSession, andCrossChainTestCallerSession). The method bindings correctly reflect the Solidity view function, ensuring that no state modification occurs and it only reads data.
Line range hint
235-259: Correct Implementation of BridgeCoinAmount MethodThe
BridgeCoinAmountmethod is correctly implemented for retrieving the amount of coins on the bridge for a specific token and target. This implementation ensures accurate data retrieval with proper error handling.
Line range hint
260-284: Correct Implementation of CancelSendToExternal MethodThe
CancelSendToExternalmethod is correctly implemented as a transactional binding, reflecting its state-changing nature. This is consistent with the Solidity implementation which marks this as a non-view function.
Line range hint
285-309: Correct Implementation of CrossChain MethodThe
CrossChainmethod is crucial for executing cross-chain operations, and its implementation as a transactional binding in Go correctly reflects the state-changing nature of the operation. This is consistent with its Solidity counterpart.
Line range hint
310-334: Correct Implementation of IncreaseBridgeFee MethodThe
IncreaseBridgeFeemethod allows for the adjustment of bridge fees for specific transactions. Its implementation as a transactional binding in Go is correct and consistent with the Solidity definition, ensuring that the state change is handled properly.contract/contract.go (3)
21-22: Updated contract initialization code for clarity and maintainability.The initialization codes for
initFIP20CodeandinitWFXCodehave been updated. This should improve readability and maintainability by using theMustDecodeHexfunction to ensure the hex strings are correctly decoded or cause a panic if not. This is a robust way to handle potential errors during the decoding process.
48-48: Refactored to use newly addedIErrorMetaDataABI.The
errorABIvariable is correctly initialized using theMustABIJsonfunction withIErrorMetaData.ABI. This follows the changes noted in the PR summary whereIErrorABIis deprecated in favor ofIErrorMetaData.ABI, aligning with the new standards and simplifying contract interactions.
82-84: Function to access the ABI for error handling is properly implemented.The function
GetErrorABIprovides a clean and straightforward way to access theerrorABIwhich is crucial for error handling in contract interactions. This encapsulation ensures that the ABI can be modified or updated in one place without affecting the components that use this function.contract/FIP20Upgradable.go (8)
34-34: Update the contract metadata to reflect the latest ABI and Bin data.This change is in line with the PR's objective to use
FIP20UpgradableMetaData.ABIinstead of the deprecatedFIP20UpgradableABI. It ensures that the contract metadata remains accurate and up-to-date with the latest contract definition.
36-36: Deprecation of individual ABI and Bin variables.Marking
FIP20UpgradableABIandFIP20UpgradableBinas deprecated is consistent with the PR's goal to centralize contract metadata. This change helps avoid redundancy and potential inconsistencies in ABI data management.
Line range hint
38-46: Ensure proper error handling in the deployment function.The deployment function correctly checks for errors, which is crucial for preventing deployment with invalid ABI data. This robust error handling ensures that any issues with ABI parsing or contract deployment are caught early.
Line range hint
48-57: Check the implementation of contract binding functions.The struct definitions for different aspects of the contract (caller, transactor, filterer) are correctly set up. Each type is associated with a specific part of the contract functionality, which enhances modularity and clarity in contract interactions.
Line range hint
59-65: Ensure constructors handle errors appropriately.The constructor functions for creating various contract interfaces handle errors properly. This is crucial for ensuring that the contract is correctly linked and operational before any interactions occur.
Line range hint
67-73: Validate the contract binding function.The
bindFIP20Upgradablefunction correctly binds the contract address with its ABI for different functionalities (calling, transacting, filtering). It ensures that the contract interactions are correctly set up based on the provided contract address and ABI.
Line range hint
75-83: Check method implementations for standard contract functions.The implementation of standard contract methods such as
Call,Transfer, andTransactis crucial. These methods are the primary way users interact with the contract, and their correct implementation is essential for the contract's functionality.
Line range hint
85-93: Review event filtering and parsing functionalities.The event-related functionalities, such as filtering and parsing, are crucial for dApps that need to respond to contract events. These functions are implemented correctly and allow for robust interaction with contract events.
contract/WFXUpgradable.go (1)
35-35: Deprecation of old variable names in favor of new metadata structure.The use of
WFXUpgradableABIandWFXUpgradableBinis deprecated in favor of usingWFXUpgradableMetaData.ABIandWFXUpgradableMetaData.Bin. This change is positive as it centralizes the metadata information, making the code cleaner and easier to maintain.
