📝 Walkthrough

Walkthrough

This change adds utilities to retrieve pending and queued L1 mempool transactions and calculate the next matching batch index. It removes the exported ParseBusinessInfo function, its ABI decoding logic, and unused imports.

Changes

L1 mempool utility updates

Layer / File(s)	Summary
Mempool retrieval and batch index calculation tx-submitter/utils/utils.go	ParseL1Mempool calls txpool_contentFrom, reports RPC errors, and combines pending and queued transactions. ParseMempoolLatestBatchIndex filters matching transactions and returns the next batch index.
Obsolete parser removal and import cleanup tx-submitter/utils/utils.go	Removes the exported ParseBusinessInfo function and its commit/finalize classification and finalize-batch ABI decoding. Removes unused imports.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to 398fe

The change can panic when processing transactions with empty or short calldata, potentially interrupting transaction submission. Add a length check before slicing; merge should wait until this is fixed.

In `@tx-submitter/utils/utils.go`:
- Around line 180-182: Guard the transaction loop before the selector comparison
so transactions with calldata shorter than four bytes are skipped instead of
slicing tx.Data() unsafely. Update the logic around ParseParentBatchIndex to
check the calldata length first, while preserving selector matching for valid
calldata.
