January 2026: Delivered a critical robustness improvement in XRPLD (XRPLF/rippled) by fixing the Batch Transaction Fee Validation logic. The fix ensures inner transactions have zero fees, properly handles negative and non-integer fees, and reorders Batch Preflight Errors to clarify failure causes, aligning behavior with issue #6058. This work reduces the risk of invalid batch submissions and improves reliability of batch processing in production.
