32-33: LGTM: New CheckTxHandler type added correctly.The new CheckTxHandler type is well-structured and follows the pattern of existing handlers in the file. It correctly uses generics with transaction.Tx, which aligns with best practices for type-safe code.
Consider adding a brief comment explaining the purpose and usage of this handler, similar to the comments for other handler types in this file. This would improve code readability and maintainability. For example:
// CheckTxHandler is a function type that handles the checking of a transaction. // It takes a function that executes the transaction check and returns a CheckTxResponse and an error.server/v2/cometbft/options.go (1)
21-21: LGTM! Consider adding a comment for the new field.The addition of the
CheckTxHandlerfield is consistent with the structure and naming conventions of theServerOptionsstruct. It's correctly typed and placed logically among other handler fields.Consider adding a brief comment explaining the purpose of the
CheckTxHandlerfield, similar to other fields in the struct. This would improve code documentation and maintainability.server/v2/cometbft/abci.go (2)
67-67: Add a comment explainingcheckTxHandlerfieldTo enhance code readability, consider adding a comment describing the purpose of the
checkTxHandlerfield in theConsensusstruct.Apply this diff to add the comment:
+ // checkTxHandler handles custom logic for CheckTx if provided. checkTxHandler handlers.CheckTxHandler[T]
142-142: Improve comment capitalization and clarityThe comment should start with a capital letter and form a complete sentence for better readability.
Apply this diff to improve the comment:
- // we do not want to return a cometbft error, but a check tx response with the error + // We do not want to return a CometBFT error but a CheckTx response with the error.

8-8: LGTM: New import added correctly.The new import for "cosmossdk.io/core/server" is correctly placed and follows the Uber Go Style Guide's recommendations for import formatting. This import is necessary for the new CheckTxHandler type.

39-39: Clarify thenilinitialization ofCheckTxHandler.Unlike other handlers in
DefaultServerOptions,CheckTxHandleris initialized tonil. This approach might lead to potential issues:
- It's inconsistent with other handlers' initialization.
- It could cause nil pointer dereferences if not properly handled where this handler is used.
Consider the following options:
- Provide a default no-op implementation, similar to other handlers.
- If
nilis intentional, add a comment explaining why it's different from other handlers.- If it's truly optional, consider using a pointer type to make the optionality explicit.
To ensure this doesn't cause issues elsewhere in the codebase, let's check for nil checks:
✅ Verification successful
Initialization of
CheckTxHandleris safe asnilchecks are appropriately handled.
- No instances found where
CheckTxHandleris used without null checks.🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Search for usage of CheckTxHandler without nil checks rg --type go 'CheckTxHandler' -C 5 | rg -v 'if.*nil'Length of output: 7303

116-116: LGTM: Addition of checkTxHandler aligns with PR objectivesThe addition of
checkTxHandlerto theconsensusobject is consistent with the PR's objective of adding a CheckTx handler. This change enhances the flexibility of transaction validation within the consensus mechanism.A few observations:
- The implementation follows Go naming conventions.
- The assignment is consistent with other handler assignments in this method.
- This addition doesn't appear to introduce any breaking changes to existing functionality.
To ensure this change is properly integrated, let's verify its usage:
✅ Verification successful
CheckTxHandler integration is correctly implemented and consistent
The addition of
checkTxHandlerinserver/v2/cometbft/server.goaligns with existing usages ofCheckTxHandleracross the codebase. Assigning it froms.serverOptions.CheckTxHandlerfollows established patterns, ensuring proper integration without introducing breaking changes.🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Search for CheckTxHandler definition and usage rg --type go 'CheckTxHandler'Length of output: 1169
server/v2/cometbft/abci.go (2)
140-165: Proper conditional handling inCheckTxmethodThe conditional statement appropriately checks for the presence of a custom
checkTxHandlerand falls back to the default validation logic when it's nil. The error handling and response construction are correctly implemented.
168-168: Correct use ofcheckTxHandlerThe invocation of
c.checkTxHandler(c.app.ValidateTx)correctly passes the application'sValidateTxfunction to the custom handler.
