Walkthrough

The method attempt_gas_bump_for_stalled_nonce in the executors/src/eoa/worker/confirm.rs file was updated to handle cases where there are submitted transactions for an expected nonce but no transaction is found for gas bumping. Now, a noop transaction is sent in such cases, and logging was added. Early return statements were also refactored.

344-344: LGTM! Cleaner Rust idiom.

Removing explicit return statements makes the code more idiomatic since Rust automatically returns the last expression in a block.

Also applies to: 354-354

357-366: Effective fallback mechanism for stuck nonces.

This change addresses the core issue by providing a fallback when submitted transactions exist but no suitable gas bump candidate is found. Sending a noop transaction is a reasonable approach to unstuck the nonce in this edge case scenario.

The debug log message clearly explains the situation, which will aid in debugging if this path is frequently taken.
