1-12: Review of package and imports:The package name
astria_sequencerand the imports are appropriate for the functionality being implemented. The use of specific imports likeastriaprotoandtxprotoindicates a well-structured approach to handling specific protocol buffer models, which is crucial for the sequencer's functionality.The structure and imports are approved.
22-38: Review ofNewconstructor:The constructor function
Newis well-implemented with proper error handling and initialization of theSequencertype. The use of Go's error wrapping in lines 26 and 31 enhances the error information, aiding in debugging and maintenance.The constructor implementation is approved.
go.mod (1)
1-64: Review of Go module and dependencies:The
go.modfile is well-structured with a clear definition of the module path and required dependencies. The specified Go version, 1.22.5, is appropriate for the current standards. The dependencies are well-documented with specific versions, ensuring reproducible builds and compatibility.The Go module configuration and dependencies are approved.

Implement stub methods:
Both GetNextBatch and VerifyBatch methods are currently implemented as stubs with panic("implement me"). These methods are essential for the sequencer's operation and need to be fully implemented to handle batch transactions effectively.
Would you like me to help with the implementation or open a GitHub issue to track this task?

Address TODO and verify transaction logic:
The SubmitRollupTransaction method is crucial for the functionality of the sequencer. However, there is a TODO comment on line 49 regarding the handling of FeeAsset. This needs to be addressed to ensure complete transaction processing. Additionally, the method uses panic for error handling on line 58, which is not advisable in production code as it can terminate the program unexpectedly.
Consider replacing panic with more robust error handling. Also, resolve the TODO about FeeAsset to ensure the transaction logic is complete.
- panic(err)
+ return fmt.Errorf("failed to sign transaction: %w", err)Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
