We are upgrading our World Chain Mainnet infrastructure to v2.4.1.

This release includes improved RPC simulation functionality with better visibility into nested halt reasons and trace data, AWS KMS support for proof infrastructure, and multiple stability and correctness fixes across the proof system and transaction pool.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
eth_simulateV1 — Improved handling with flashblocks support and better revert reason surfacing for nested simulation halts.
simulate — Enhanced trace outcomes with improved CALL and CREATE trace data visibility and more accurate revert reason reporting.
