SetToken method is no longer utilized and should be removed
The
SetTokenmethod inx/crosschain/keeper/keeper_v1_test.gois defined but not invoked in any test cases after being commented out. To maintain code cleanliness and ensure comprehensive test coverage, it is recommended to:
- Remove the
SetTokenmethod entirely if it is no longer needed.- Update or remove any related tests that previously relied on this method to prevent potential confusion or maintenance issues.
🔗 Analysis chain
Consider the impact of commenting out the
SetTokenmethodThe commented-out
SetTokenmethod aligns with the PR objective of refactoring the many-to-one logic. However, this change raises some concerns:
- Test coverage may be impacted by removing this functionality without a replacement.
- Any tests calling this method might now silently skip important setup steps.
Consider the following suggestions:
- If the method is no longer needed, remove it entirely and update all calling tests.
- If the functionality is still required but in a different form, provide a placeholder implementation or update the method to reflect the new logic.
- Ensure all tests that previously relied on this method are updated or adjusted accordingly.

⚠️ Potential issueChanging field types without changing field numbers may break backward compatibility
In
QueryTokenPairResponse, the type of field1has been changed fromTokenPairtoERC20Token. This modification can disrupt clients that rely on the original message structure, causing potential deserialization failures.To preserve backward compatibility, add the new field with a different field number and deprecate the old one. Here's the suggested modification:
message QueryTokenPairResponse { option deprecated = true; + TokenPair token_pair = 1 [ (gogoproto.nullable) = false, deprecated = true ]; + ERC20Token erc20_token = 2 [ (gogoproto.nullable) = false ]; }Committable suggestion was skipped due to low confidence.

⚠️ Potential issueWrap Internal Errors with Appropriate gRPC Status Codes
In both
TokenPairandParamsmethods, errors returned froms.k.ERC20Token.Getands.k.Params.Getare directly passed back to the client without wrapping them in gRPC status errors. This might expose internal error details and doesn't provide clear status codes to the client. Wrap these errors with appropriate gRPC status codes to enhance error handling.Apply these diffs to wrap the errors:
// In TokenPair method - return nil, err + return nil, status.Errorf(codes.Internal, "failed to retrieve ERC20 token: %v", err)// In Params method - return nil, err + return nil, status.Errorf(codes.Internal, "failed to retrieve parameters: %v", err)Also applies to: 80-80

⚠️ Potential issueEnsure atomicity in minting and transferring coins
After minting coins to the module account in
ConvertERC20NativeToken, coins are sent to the receiver. If an error occurs duringSendCoinsFromModuleToAccount, the module account retains the minted coins, leading to inconsistencies.Implement error handling or state rollback to maintain atomicity:
- Use a transactional approach if supported.
- Alternatively, consider burning the minted coins in case of a failure to send them to the receiver.

9-18: Approve new CheckEnableErc20 method with a minor suggestion.The new
CheckEnableErc20method effectively encapsulates the logic for checking if the ERC20 module is enabled. It properly handles potential errors from parameter retrieval and uses a custom error type for clear error messaging.Consider wrapping the error returned from

1-18: Summary of changes and potential impact.The modifications to
params.gorepresent a significant refactoring of parameter management in the ERC20 module:
- The shift from SDK-specific context to standard Go context improves compatibility and aligns with modern Go practices.
- The new
CheckEnableErc20method provides a focused way to check if the ERC20 module is enabled.- The removal of several methods (
GetParams,SetParams,GetEnableEVMHook,GetIbcTimeout) suggests a broader change in how parameters are accessed and managed throughout the module.These changes likely improve the module's structure and maintainability. However, they may have far-reaching implications across the codebase. Ensure that all affected parts of the code have been updated accordingly, and consider updating the module's documentation to reflect these significant changes in parameter management.
Consider creating a comprehensive guide or updating existing documentation to explain the new parameter management approach. This will help other developers understand and correctly use the new system.

AddBridgeTokenmethod is thorough in its implementation, checking for existing tokens, constructing a newBridgeTokenobject, and updating bothBridgeTokenandDenomIndexcollections. The error handling is generally good, but there's room for a small improvement.Consider wrapping the error returned from
k.DenomIndex.Set()on line 41 to provide more context:- return k.DenomIndex.Set(ctx, bridgeToken.BridgeDenom(), baseDenom) + if err := k.DenomIndex.Set(ctx, bridgeToken.BridgeDenom(), baseDenom); err != nil { + return fmt.Errorf("failed to set DenomIndex: %w", err) + } + return nilThis change would make it easier to debug if an error occurs during the
DenomIndexupdate.x/erc20/keeper/msg_server.go (4)
20-23: LGTM: Well-implemented constructor functionThe
NewMsgServerImplfunction correctly initializes and returns a newmsgServerinstance. This is a good practice for object creation.Consider returning
msgServerdirectly instead of&msgServerfor consistency with the interface declaration on line 14:func NewMsgServerImpl(k Keeper) types.MsgServer { - return &msgServer{ + return msgServer{ k: k, } }
26-31: LGTM: Correct implementation of ConvertCoin methodThe
ConvertCoinmethod is correctly implemented for themsgServertype. It properly unwraps the context, processes the message, and calls the corresponding method on the encapsulatedKeeper.Consider wrapping the error returned from
s.k.ConvertCoinwith additional context:func (s msgServer) ConvertCoin(c context.Context, msg *types.MsgConvertCoin) (*types.MsgConvertCoinResponse, error) { ctx := sdk.UnwrapSDKContext(c) sender := sdk.MustAccAddressFromBech32(msg.Sender) receiver := common.HexToAddress(msg.Receiver) - _, err := s.k.ConvertCoin(ctx, sender, receiver, msg.Coin) - return &types.MsgConvertCoinResponse{}, err + _, err := s.k.ConvertCoin(ctx, sender, receiver, msg.Coin) + if err != nil { + return nil, errorsmod.Wrap(err, "failed to convert coin") + } + return &types.MsgConvertCoinResponse{}, nil }This provides more context in case of an error, which can be helpful for debugging.
34-42: LGTM: Correct implementation of UpdateParams methodThe
UpdateParamsmethod is correctly implemented for themsgServertype. It properly checks the authority and updates the parameters using the encapsulatedKeeper'sParams.For consistency with other methods, consider unwrapping the context at the beginning of the method:
func (s msgServer) UpdateParams(c context.Context, req *types.MsgUpdateParams) (*types.MsgUpdateParamsResponse, error) { if s.k.authority != req.Authority { return nil, errorsmod.Wrapf(govtypes.ErrInvalidSigner, "invalid authority; expected %s, got %s", s.k.authority, req.Authority) } - ctx := sdk.UnwrapSDKContext(c) + ctx := sdk.UnwrapSDKContext(c) if err := s.k.Params.Set(ctx, req.Params); err != nil { return nil, err } return &types.MsgUpdateParamsResponse{}, nil }This makes the context unwrapping consistent across all methods in the file.
45-53: LGTM: Correct implementation of ToggleTokenConversion methodThe
ToggleTokenConversionmethod is correctly implemented for themsgServertype. It properly checks the authority and calls the corresponding method on the encapsulatedKeeper.Consider the following improvements for consistency and better error handling:
- Unwrap the context at the beginning of the method.
- Wrap the error returned from
s.k.ToggleTokenConvertwith additional context.func (s msgServer) ToggleTokenConversion(c context.Context, req *types.MsgToggleTokenConversion) (*types.MsgToggleTokenConversionResponse, error) { + ctx := sdk.UnwrapSDKContext(c) if s.k.authority != req.Authority { return nil, errorsmod.Wrapf(govtypes.ErrInvalidSigner, "invalid authority; expected %s, got %s", s.k.authority, req.Authority) } - erc20Token, err := s.k.ToggleTokenConvert(c, req.Token) + erc20Token, err := s.k.ToggleTokenConvert(ctx, req.Token) if err != nil { - return nil, err + return nil, errorsmod.Wrap(err, "failed to toggle token conversion") } return &types.MsgToggleTokenConversionResponse{Erc20Token: erc20Token}, nil }These changes improve consistency with other methods and provide more context in case of an error.

23-23: LGTM: Method signature improved for clarity and specificity.The changes to the method signature enhance its descriptiveness and clarity:
- Renaming from
EvmTokenToBasetoEvmTokenToBaseCoinbetter describes the method's functionality.- Renaming the parameter from
tokentotokenAddris more precise.- Adding
sdk.Cointo the return type provides more specific information about the result.These changes align well with good coding practices and improve the API's clarity.
Consider updating any existing documentation or comments related to this method to reflect these changes.
24-48: LGTM: Method logic improved and error handling enhanced.The changes in the method body improve the code's clarity and error handling:
- Simplified logic for retrieving
erc20Tokenenhances readability.- Updated conditional checks using
erc20Tokenproperties align with the new structure.- The new error case for invalid ERC20 token ownership improves error specificity.
These changes contribute to more robust and maintainable code.
Consider wrapping the error returned from
crossChainKeeper.GetBaseDenomByErc20to provide more context:erc20Token, err := crossChainKeeper.GetBaseDenomByErc20(ctx, tokenAddr) if err != nil { return sdk.Coin{}, fmt.Errorf("failed to get base denom for ERC20 token %s: %w", tokenAddr, err) }This change would make debugging easier by providing more information about where the error occurred.
x/erc20/keeper/grpc_query.go (3)
26-42: LGTM: ImprovedTokenPairsimplementation with a minor suggestionThe updated
TokenPairsmethod is well-implemented. The use ofquery.CollectionPaginateis an improvement over the previous prefix store approach. The response structure change toErc20Tokensaligns well with the updated data model.Consider wrapping the error returned from
query.CollectionPaginatewith additional context:if err != nil { - return nil, status.Error(codes.Internal, err.Error()) + return nil, status.Errorf(codes.Internal, "failed to paginate ERC20 tokens: %v", err) }This will provide more informative error messages for debugging.
47-70: LGTM: Well-implementedTokenPairmethod with a suggestionThe updated
TokenPairmethod is well-structured and handles both Ethereum addresses and SDK denoms effectively. The use ofDenomIndexandERC20Tokenstores is efficient.Consider adding a more specific error message when the ERC20 token is not found:
erc20Token, err := s.k.ERC20Token.Get(c, baseDenom) if err != nil { - return nil, status.Error(codes.NotFound, err.Error()) + return nil, status.Errorf(codes.NotFound, "ERC20 token not found for base denom %s: %v", baseDenom, err) }This will provide more context in the error message, which can be helpful for debugging and client-side error handling.
Line range hint
1-79: Overall: Excellent refactoring of the query server implementationThe changes in this file represent a significant improvement in the query server implementation for the ERC20 module. The introduction of the
queryServerstruct with an encapsulatedKeeperpromotes better separation of concerns and modularity. The updated methods (TokenPairs,TokenPair, andParams) are more efficient and align well with the new data structures.Key improvements:
- Better abstraction with the
queryServerstruct- More efficient pagination in
TokenPairsusingquery.CollectionPaginate- Improved token pair retrieval logic in
TokenPair- Simplified parameter retrieval in
ParamsThese changes should result in a more maintainable and performant query server implementation.
Consider adding unit tests for the new
queryServermethods to ensure their correctness and to guard against future regressions.x/crosschain/keeper/bridge_token.go (3)
15-36: LGTM: Improved token validation and error handling.The refactored
AddBridgeTokenExecutedfunction now leverageserc20Keeperfor token validation, which aligns with the overall goal of centralizing ERC20 token management. The error messages are more specific and informative.However, consider wrapping the error returned from
k.erc20Keeper.HasTokento provide more context:if err != nil { return fmt.Errorf("failed to check if bridge token exists: %w", err) }This will help in debugging by providing more information about where the error occurred.
41-66: LGTM: Improved handling of IBC and bridge tokens.The refactored
BridgeCoinSupplyfunction now clearly separates the logic for IBC and bridge tokens, which improves readability and maintainability. The use oferc20Keepermethods for token information retrieval is consistent with the overall refactoring strategy.Consider adding more context to the error returned from
k.erc20Keeper.GetBaseDenom:baseDenom, err := k.erc20Keeper.GetBaseDenom(ctx, token) if err != nil { return sdk.Coin{}, fmt.Errorf("failed to get base denom for token %s: %w", token, err) }This will provide more information about which token caused the error, aiding in debugging.
69-74: LGTM: Improved ERC20 token information retrieval.The refactored
GetBaseDenomByErc20function now returns a more comprehensiveerc20types.ERC20Tokeninstead of just a string and boolean. This change provides more detailed information about the ERC20 token, which is beneficial for consumers of this function.Consider adding more context to the errors returned:
baseDenom, err := k.erc20Keeper.GetBaseDenom(ctx, erc20Addr.String()) if err != nil { return erc20types.ERC20Token{}, fmt.Errorf("failed to get base denom for ERC20 address %s: %w", erc20Addr.String(), err) } token, err := k.erc20Keeper.GetERC20Token(ctx, baseDenom) if err != nil { return erc20types.ERC20Token{}, fmt.Errorf("failed to get ERC20 token for base denom %s: %w", baseDenom, err) } return token, nilThis will provide more detailed error messages, which can be helpful for debugging.
x/crosschain/precompile/crosschain.go (4)
58-61: Improved target address parsing and validation.The introduction of
crosschaintypes.ParseFxTargetenhances the robustness of target address handling. This change is a positive step towards better input validation.Consider wrapping the error returned by
ParseFxTargetwith additional context to aid in debugging:fxTarget, err := crosschaintypes.ParseFxTarget(fxtypes.Byte32ToString(args.Target)) if err != nil { - return err + return fmt.Errorf("failed to parse target address: %w", err) }
66-68: Enhanced external address validation.The addition of
ValidateExternalAddrimproves the security and reliability of the cross-chain operation by ensuring the validity of the external address.Consider wrapping the error returned by
ValidateExternalAddrwith additional context:if err = fxTarget.ValidateExternalAddr(args.Receipt); err != nil { - return err + return fmt.Errorf("invalid external address: %w", err) }
70-74: Improved logic for handling origin tokens and amount validation.The introduction of
isOriginTokenand the simplified calculation oftotalAmountenhance the readability and maintainability of the code.Consider adding a comment to explain the significance of
value.Sign() > 0:+ // isOriginToken is true when the transaction includes a non-zero value, + // indicating that the origin token is being used. isOriginToken := value.Sign() > 0
78-80: Added validation for token address when using origin token.This check ensures consistency between the use of origin tokens and the provided token address, preventing potential misuse.
Consider adding a comment to explain why the token address should be zero for origin tokens:
+ // For origin token transactions, the token address should be zero + // as the native token is being used. if !fxcontract.IsZeroEthAddress(args.Token) { return errors.New("token is not zero address") }x/erc20/keeper/keeper.go (3)
21-40: LGTM: Keeper struct updated with collections-based fields.The changes to the
Keeperstruct, including the replacement ofstoreKeywithstoreServiceand the addition of new fields using thecollectionspackage, are well-structured and align with modern Cosmos SDK practices.Consider adding inline documentation for each new field to explain their purpose and usage, especially for the
collections.Mapfields. This will help other developers understand the structure more easily.
46-46: LGTM: NewKeeper function updated correctly.The
NewKeeperfunction has been properly updated to usestoreServiceand initialize the new collection-based fields. The use ofcollections.NewSchemaBuilderand the subsequent initialization of collection fields are well-implemented.Consider wrapping the error returned from
sb.Build()with additional context before panicking. This could help with debugging in case of schema building failures. For example:schema, err := sb.Build() if err != nil { panic(fmt.Errorf("failed to build erc20 keeper schema: %w", err)) }Also applies to: 58-80
88-116: LGTM: MintingEnabled method implemented correctly.The new
MintingEnabledmethod is well-structured and implements necessary checks before allowing ERC20 minting. It properly handles different scenarios and returns appropriate errors.Consider grouping related checks together for better readability. For example, you could move the
bankKeeper.BlockedAddrcheck right after theerc20Token.Enabledcheck, as they are both related to the receiver's eligibility. This would make the logical flow of the checks more apparent:if !erc20Token.Enabled { return erc20Token, types.ErrDisabled.Wrapf("token %s is disabled", erc20Token.Denom) } if k.bankKeeper.BlockedAddr(receiver.Bytes()) { return erc20Token, sdkerrors.ErrUnauthorized.Wrapf("%s is not allowed to receive transactions", receiver) } if !k.bankKeeper.IsSendEnabledDenom(ctx, erc20Token.Denom) { return erc20Token, banktypes.ErrSendDisabled.Wrapf("minting '%s' denom is currently disabled", tokenName) }x/crosschain/types/expected_keepers.go (2)
68-70: New EvmERC20Keeper interface added for EVM-specific ERC20 operations.The introduction of the
EvmERC20Keeperinterface with theTotalSupplymethod is a good addition for handling EVM-specific ERC20 operations. The method signature is appropriate, usingcontext.Contextand returning a*big.Intfor precise handling of token supplies.Consider adding a brief comment above the interface to explain its purpose and how it differs from the
Erc20Keeperinterface. This would improve the overall documentation and make it easier for other developers to understand the distinction between these interfaces.
74-74: New SetDenomTrace method added to IBCTransferKeeper interface.The addition of the
SetDenomTracemethod to theIBCTransferKeeperinterface is a good improvement. It complements the existingGetDenomTracemethod, allowing for both setting and retrieving denom traces, which is crucial for IBC transfers.For consistency, consider updating the
GetDenomTracemethod signature to usesdk.Contextinstead ofcontext.Context, matching the newly addedSetDenomTracemethod. This would ensure a uniform approach across the interface.x/crosschain/keeper/many_to_one.go (4)
16-32: LGTM! Consider adding a comment for clarity.The
BridgeTokenToBaseCoinfunction looks well-implemented. It correctly handles the conversion of bridge tokens to base coins, taking into account whether the token is an origin token or not. The error handling is appropriate.Consider adding a brief comment explaining the purpose of this function and the difference in handling between origin and non-origin tokens. This would improve code readability and maintainability.
35-52: LGTM! Consider adding error wrapping.The
BaseCoinToBridgeTokenfunction is well-implemented. It correctly handles the conversion of base coins to bridge tokens, taking into account whether the token is native or not. The error handling is appropriate.Consider wrapping errors with additional context using
fmt.Errorfor a similar method. This would provide more information about where and why an error occurred, making debugging easier. For example:if err != nil { return bridgeToken, fmt.Errorf("failed to get bridge token: %w", err) }
55-72: LGTM! Consider adding a comment for clarity.The
DepositBridgeTokenfunction is well-implemented. It correctly handles the deposit of bridge tokens, taking into account whether the token is an origin token or not. The error handling is appropriate.Consider adding a brief comment explaining the purpose of this function and the difference in handling between origin and non-origin tokens. This would improve code readability and maintainability.
126-135: LGTM! Consider adding logging for better traceability.The
IBCCoinToEvmfunction is well-implemented. It correctly handles the conversion of IBC coins to EVM-compatible tokens, including the case where the base denomination is not found.Consider adding some logging statements to improve traceability, especially in the case where the base denomination is not found. This could help with debugging and monitoring. For example:
if baseDenom == "" { k.Logger(ctx).Info("Base denomination not found for IBC coin", "denom", ibcCoin.Denom) return nil }x/crosschain/keeper/grpc_query.go (3)
195-199: LGTM! Consider enhancing error handling.The changes to
DenomToTokenmethod look good. Usingerc20Keeper.GetBridgeTokenimproves encapsulation and potentially efficiency. The error handling is consistent with gRPC status codes.Consider adding more context to the error message:
- return nil, status.Error(codes.NotFound, err.Error()) + return nil, status.Errorf(codes.NotFound, "bridge token not found for denom %s: %v", req.Denom, err)This will provide more informative error messages for debugging and logging purposes.
206-214: LGTM! Consider optimizing for performance.The changes to
TokenToDenommethod look good. Usingerc20Keeper.GetBaseDenomanderc20Keeper.GetBridgeTokenimproves encapsulation. The error handling is consistent with gRPC status codes.Consider combining the two keeper calls to improve performance:
baseDenom, bridgeToken, err := k.erc20Keeper.GetBaseDenomAndBridgeToken(c, req.Token, req.ChainName) if err != nil { return nil, status.Errorf(codes.NotFound, "token not found or not bridged: %v", err) } return &types.QueryTokenToDenomResponse{Denom: baseDenom}, nilThis would require implementing a new method
GetBaseDenomAndBridgeTokenin theerc20Keeper, but it could potentially reduce database lookups and improve overall performance.
295-299: LGTM! Consider enhancing error handling.The changes to
BridgeCoinByDenommethod look good. Usingk.BridgeCoinSupplyinstead ofk.GetBridgeCoinSupplysuggests a refactoring in the keeper, which is fine. The error handling is consistent with gRPC status codes.Consider adding more context to the error message:
- return nil, status.Error(codes.Internal, err.Error()) + return nil, status.Errorf(codes.Internal, "failed to get bridge coin supply for denom %s: %v", req.GetDenom(), err)This will provide more informative error messages for debugging and logging purposes.

12-14: Improved error handling in InitGenesisThe function signature now returns an error, allowing for better error propagation. The use of
k.Params.Setwith error checking is a good practice.
20-20: Enhanced error handling for module account checkReplacing the panic with an error return is a good practice for better error handling and system stability.
31-35: Improved error handling in ExportGenesisThe function now properly handles errors during parameter retrieval, which is a good practice. The signature change to return an error is consistent with the improvements in error handling throughout the file.
1-38: Summary of changes and areas for verificationThe changes in this file significantly improve error handling and simplify implementations. Key improvements include:
- Both
InitGenesisandExportGenesisnow return errors, allowing for better error propagation.- The use of
k.Params.Setandk.Params.Getwith error checking enhances robustness.- Panic statements have been replaced with error returns, improving system stability.
However, some areas require further verification:
- The removal of the token pair initialization loop in
InitGenesis. Ensure this functionality is not needed or has been moved elsewhere.- The simplification of the exported genesis state in
ExportGenesis. Verify that all necessary data is still being included.These changes align with best practices for error handling and code simplification, but it's crucial to ensure that no critical functionality has been lost in the process.
#!/bin/bash # Description: Check for potential impacts of the changes # Search for uses of InitGenesis and ExportGenesis rg --type go 'InitGenesis|ExportGenesis' -g '!*_test.go' # Search for token pair or ERC20 token handling rg --type go 'TokenPair|ERC20Token' -g '!*_test.go'

1-116: Verify the impact of removed methods.Several methods have been removed from the
Keeperstruct, includingGetAuthority,ModuleAddress, andTransferAfter. While these changes align with the refactoring towards collections-based management, it's crucial to ensure that the removed functionality is either no longer needed or has been appropriately replaced elsewhere in the codebase.Please run the following script to check for any remaining usage of the removed methods:
If any usages are found, please ensure they are updated or removed as necessary.
✅ Verification successful
Verification Successful: Removed Keeper methods are unused.
The shell script confirmed that
GetAuthority,ModuleAddress, andTransferAfterare no longer used within theKeeperstruct. Their implementations in other parts of the codebase do not impact this removal.🏁 Scripts executed

46-59: Improved Erc20Keeper interface with enhanced token management and caching capabilities.The new methods added to the
Erc20Keeperinterface significantly improve its functionality:
- Introduction of caching methods (
HasCache,SetCache,DeleteCache) which can potentially optimize performance.- Enhanced token management with methods like
HasToken,GetBaseDenom,GetERC20Token,GetBridgeToken, andGetIBCToken.- Addition of
BaseCoinToEvmmethod for coin conversion.These changes provide a more granular and flexible approach to token handling in the crosschain module. The consistent naming convention and clear method signatures contribute to improved readability and maintainability.

1-93: Significant refactoring of keeper interfaces for improved ERC20 and IBC operations.The changes in this file represent a substantial refactoring of the keeper interfaces, particularly for ERC20 and IBC operations. Key points:
- Removal of several methods from the
Erc20Keeperinterface (e.g.,GetTokenPair,ConvertCoin,ConvertERC20).- Addition of new methods to
Erc20Keeperfor enhanced token management and caching.- Introduction of a new
EvmERC20Keeperinterface.- Update to the
IBCTransferKeeperinterface with a newSetDenomTracemethod.These changes suggest a shift in the architecture of the crosschain module, likely aimed at improving efficiency and flexibility in handling ERC20 tokens and IBC transfers.
To ensure these changes are properly implemented and don't introduce breaking changes, please run the following verification script:
This script will help identify any areas of the codebase that might need updates due to these interface changes.

75-84: LGTM! Well-implemented withdrawal logic.The
WithdrawBridgeTokenfunction is correctly implemented. It appropriately handles the withdrawal of bridge tokens, taking into account whether the token is an origin/native token or not. The error handling is suitable, and the logic for burning non-origin, non-native tokens is correct.
166-171: LGTM! Well-implemented token retrieval.The
GetBridgeTokenfunction is correctly implemented. It appropriately uses the erc20Keeper to first get the base denomination and then retrieve the bridge token. The error handling is suitable.x/erc20/types/msg.go (7)
34-34: Clearer error message for sender address validation — Good improvement!The updated error message specifies "sender address," enhancing clarity when debugging address-related issues.

40-40: Enhanced error message for coin denomination validation — Well done!Providing "coin denom" in the error message offers better insight into denomination-related errors.
50-50: Specific error message for authority address validation — Good job!Including "authority address" in the error message enhances clarity when the authority address is invalid.
53-53: Improved error message for parameter validation — Nice enhancement!By specifying "params" in the error message, it becomes clearer that there's an issue with the parameters provided.
68-68: Clear error message for authority address in token conversion — Looks good!The updated message improves clarity by indicating the error originates from the "authority address."
72-72: Detailed error message for token denomination validation — Excellent!Explicitly mentioning "token denom" helps in quickly identifying issues with the token denomination during validation.
