43-43: Approve the type cast with a minor suggestion.The change to cast
evmtypes.EighteenDecimalstoint64improves type safety by ensuring the argument matches the expected type forWithEVMCoinInfo. This aligns with the PR's objective of refactoring the configurator.For improved clarity and to make the intent more explicit, consider using a named constant or a comment to explain the significance of 18 decimals in this context.
Here's a suggestion to improve readability:
- WithEVMCoinInfo(baseDenom, int64(evmtypes.EighteenDecimals)). + WithEVMCoinInfo(baseDenom, int64(evmtypes.EighteenDecimals)). // 18 decimals for EVM compatibilityAlternatively, if
EighteenDecimalsis used in multiple places, consider defining a named constant:const EVMDecimalPrecision int64 = 18 // Then use it in the function call WithEVMCoinInfo(baseDenom, EVMDecimalPrecision)This would enhance code readability and maintainability.

109-109: Approve the type casting change with a minor suggestion.The modification to cast
decimalstoint64aligns with the PR objectives of abstracting away the Decimals type. This change improves type consistency and safety.For improved clarity, consider adding a comment explaining the reason for the type cast:
- WithEVMCoinInfo(denom, int64(decimals)). + WithEVMCoinInfo(denom, int64(decimals)). // Cast to int64 to match the updated WithEVMCoinInfo signatureThis comment would help future developers understand the reasoning behind the cast without needing to check the

110-111: Investigate suppressed static checks for GetEVMCoinDenom and GetEVMCoinDecimals.The static check suppression comments for
GetEVMCoinDenomandGetEVMCoinDecimalssuggest that these functions might be deprecated or have known issues. While they are necessary for the current test setup, it's important to investigate why they're triggering static check warnings.Consider the following actions:
- Review the reasons for these static check warnings.
- Determine if there are newer, recommended alternatives to these functions.
- If alternatives exist, update the code to use them.
- If these functions are still necessary, document the reasons for suppressing the static checks to improve code maintainability.

1-270: Overall assessment of changesThe changes in this file consistently modify the
WithEVMCoinInfomethod calls to cast theDecimalsfield toint64. While this change likely aligns with updates in the method signature, it introduces a potential for integer overflow in multiple locations.Consider the following recommendations:
- Implement the suggested overflow checks consistently across all test functions where the casting occurs.
- Review the
WithEVMCoinInfomethod signature in the actual implementation to ensure it expectsint64. If possible, consider usinguint64forDecimalsto avoid the need for casting and potential overflow issues.- Add a test case that specifically checks the behavior with a large
Decimalsvalue to ensure the system handles such cases correctly.These changes will improve the robustness of the tests and help prevent potential issues in edge cases.

123-123: Suggest additional test casesWhile the existing test suite is comprehensive, it would be beneficial to add specific test cases for the

- A test with
cfg.Decimalsset to the maximum allowed value.- A test with
cfg.Decimalsset to 0.- If applicable, a test with
cfg.Decimalsset to a value that would cause an overflow when cast toint64.These additional tests will help verify the robustness of the
WithEVMCoinInfomethod with different decimal values.🧰 Tools

123-123: Approve change with a caveatThe change from
cfg.Decimalstoint64(cfg.Decimals)addresses a type mismatch issue. However, this cast could potentially lead to an integer overflow ifcfg.Decimalsis auint64with a value greater thanmath.MaxInt64.To ensure this change doesn't introduce any overflow issues, we should verify the possible values of
cfg.Decimals. Can you provide more context on the range of valuescfg.Decimalscan take? If it's guaranteed to be within theint64range, this change is safe. Otherwise, we might need to add a check before the cast.🧰 Tools

31-31: LGTM: Updating 'Decimals' type touint64Changing the
Decimalstype fromuint32touint64provides a wider range for future decimal values, enhancing the flexibility of the code.
33-44: Well-implementedValidatemethod forDecimalsThe
Validatemethod effectively checks for supported decimal values (SixDecimalsandEighteenDecimals), enhancing input validation and robustness.
74-80: Improved error handling insetEVMCoinDecimalsRefactoring
setEVMCoinDecimalsto return an error instead of panicking improves application stability by allowing callers to handle invalid decimal values gracefully.
84-89: Enhanced error handling insetEVMCoinDenomUpdating
setEVMCoinDenomto return an error when the denomination is invalid, rather than panicking, enhances robustness and allows for better error management.
104-117: RefactoredsetEVMCoinInfofor better error handlingBy modifying
setEVMCoinInfoto return errors and integrating the updated helper functions (setEVMCoinDenomandsetEVMCoinDecimals), the code now handles configuration errors more gracefully, improving maintainability and robustness.x/evm/types/configurator.go (4)
28-28: Field renamed toevmCoinInfoThe field
evmDenomhas been renamed toevmCoinInfoin theEVMConfiguratorstruct, which improves clarity by better representing the data it holds.
80-81: Correct integration ofextendDefaultExtraEIPsThe
extendDefaultExtraEIPsfunction is correctly invoked to handle additional EIPs, enhancing configurability.

nice refactor, thanks @0xstepit! 🙏 left some comments, especially I'm wondering why we're using uint64 for the decimals, there should not be a need for more than uint8

20-22: LGTM: Type change from uint32 to uint64 for DecimalsThe change from
uint32touint64for theDecimalstype increases the range of possible values, which can be beneficial for representing a wider range of decimal places. However, be aware that this change might slightly increase memory usage forDecimalsvariables and could potentially impact performance in scenarios where manyDecimalsinstances are used.The updated comment accurately reflects the change in the underlying type.
Consider documenting the rationale for this change in the package or file-level comments to provide context for future maintainers.

89-99: LGTM with suggestion: ConversionFactor method unchanged but could be improvedThe
ConversionFactormethod has been correctly adapted to work with the newDecimalstype (uint64). Its logic remains unchanged, which is appropriate as the functionality should remain the same despite the type change.However, with the expanded range of possible values for
Decimals(now uint64), it might be beneficial to handle cases whereDecimalshas values other than 6 or 18.Consider adding a default case or error handling for unexpected
Decimalsvalues:func (d Decimals) ConversionFactor() math.Int { switch d { case SixDecimals: return math.NewInt(1e12) case EighteenDecimals: return math.NewInt(1) default: // Either return an error or a sensible default // Example: // return math.NewInt(0), fmt.Errorf("unsupported decimal places: %d", d) // Or: // log.Printf("Warning: Unexpected decimal places %d, defaulting to 1", d) return math.NewInt(1) } }This change would make the method more robust and future-proof.
x/evm/types/denom_config.go (4)
35-44: LGTM:Validatemethod added with minor suggestionThe addition of the
Validatemethod forDecimalsis a good improvement, aligning with the PR objective of adding validation. It ensures that only supported decimal values (6 and 18) are accepted.However, there's a minor suggestion for improvement:
In the error message on line 42, consider using
%vinstead of%dfor formatting theDecimalsvalue. While%dworks foruint32,%vis more flexible and would continue to work if the type ofDecimalschanges in the future.- return fmt.Errorf("received unsupported decimals: %d", d) + return fmt.Errorf("received unsupported decimals: %v", d)
74-80: LGTM: Improved error handling insetEVMCoinDecimalsThe changes to
setEVMCoinDecimalsalign well with the PR objectives, improving error handling by propagating errors instead of causing panics. The use of the newValidatemethod is a good practice.As a minor optimization, you can remove the explicit
return nilat the end of the function. In Go, a function with a named return value (in this case,error) automatically returns the zero value (nilfor error) if it reaches the end of the function without a return statement.func setEVMCoinDecimals(d Decimals) error { if err := d.Validate(); err != nil { return err } evmCoinInfo.Decimals = d - return nil }This makes the code slightly more concise without changing its behavior.
84-89: LGTM: Improved error handling insetEVMCoinDenomThe changes to
setEVMCoinDenomalign well with the PR objectives, improving error handling by propagating errors instead of causing panics. The use ofsdk.ValidateDenomfor input validation is a good practice.As with the previous function, you can remove the explicit
return nilat the end of the function for a minor optimization:func setEVMCoinDenom(denom string) error { if err := sdk.ValidateDenom(denom); err != nil { return err } evmCoinInfo.Denom = denom - return nil }This makes the code slightly more concise without changing its behavior.

1-117: Reminder: Update unit tests for new validations and error handlingAs mentioned in a previous review, it's crucial to update or add unit tests to cover the new validations and error handling introduced in this refactor. This ensures that the new behavior is properly tested and helps prevent future regressions.
Specifically, consider adding tests for:
- The new
Validatemethod of theDecimalstype.- Error cases in
setEVMCoinDecimals,setEVMCoinDenom, andsetEVMCoinInfo.- The behavior when attempting to set EVM coin info multiple times.
Would you like assistance in generating these unit tests? I can provide examples or guidelines for effective test cases if needed.

95-104: Consider handling duplicate EIPs without returning an errorIn the
extendDefaultExtraEIPsfunction, returning an error when a duplicate EIP is encountered may prevent the addition of subsequent valid EIPs. Consider logging a warning or skipping the duplicate EIP instead of returning an error to allow the function to process all provided EIPs.Apply this diff to modify the duplicate EIP handling:
func extendDefaultExtraEIPs(extraEIPs []string) error { for _, eip := range extraEIPs { if slices.Contains(DefaultExtraEIPs, eip) { - return fmt.Errorf("error configuring EVMConfigurator: EIP %s is already present in the default list: %v", eip, DefaultExtraEIPs) + // Skip duplicate EIP and continue processing the rest + continue } if err := vm.ValidateEIPName(eip); err != nil { return fmt.Errorf("error configuring EVMConfigurator: %s", err) } DefaultExtraEIPs = append(DefaultExtraEIPs, eip) } return nil }

24-29: LGTM: Constants updated to new Decimals typeThe
SixDecimalsandEighteenDecimalsconstants have been correctly updated to use the newDecimalstype (uint64). The values remain unchanged, maintaining the representation of 6 and 18 decimal places respectively. This change is consistent with the modification of theDecimalstype and doesn't alter the functionality of these constants.

1-99: Overall assessment: Changes are well-implemented with room for minor improvementsThe modification of the
Decimalstype fromuint32touint64has been consistently applied throughout the file. The changes maintain existing functionality while providing an expanded range for decimal representations.Key points:
- The type change is properly reflected in the type definition, constants, and method signatures.
- Existing logic in methods like
ConversionFactorremains intact, ensuring backward compatibility.- Comments have been updated to reflect the changes accurately.
Suggestions for improvement:
- Consider adding documentation explaining the rationale behind the type change.
- The
ConversionFactormethod could be enhanced to handle a wider range ofDecimalsvalues, given the expanded range provided byuint64.Overall, the changes are well-implemented and improve the flexibility of the
Decimalstype. With the suggested minor improvements, the code would be more robust and future-proof.x/evm/types/denom_config.go (2)
13-13: LGTM: Import added for improved error handlingThe addition of the "errors" import aligns with the PR objective of improving error handling. This is a positive change that will allow for more standardized error creation and handling throughout the file.
31-31: Clarification needed:Decimalstype remainsuint32The AI summary incorrectly states that the
Decimalstype has been changed touint64, but the code shows it's stilluint32. Could you clarify if there was a decision to keep it asuint32instead of changing it touint64? If so, what were the considerations behind this decision?Additionally, given that only two specific decimal values (6 and 18) are supported as per the
Validatemethod, would it be more appropriate to use an enum or a more restrictive type?x/evm/types/configurator.go (3)
59-60: Parameter type change touint32addresses previous overflow concernThe
decimalsparameter inWithEVMCoinInfohas been changed touint32, which prevents negative values and aligns with the expected range for token decimals. This change addresses the previous concern about integer underflow when converting from a signed to an unsigned integer type.
88-93: Good practice sealing the configurator after modificationsSealing the
EVMConfiguratorafter applying modifiers ensures that it cannot be reconfigured, preventing unintended changes after initialization. This is a best practice for maintaining the integrity of the configurator's state.
