Scheduled

We are upgrading our Flow Testnet & Mainnet EVM Gateway infrastructure. The release introduces a nonce-aware transaction mempool that improves handling of out-of-order transactions from a single EOA, preventing previously dropped transactions during burst scenarios.

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