[Urgent] MegaETH Mainnet - Upgrade to v2.2.0

Scheduled for Aug 13, 00:00 - 04:00 UTC

Scheduled

We are upgrading our MegaETH Mainnet infrastructure to v2.2.0 to support the mandatory Rex6 hardfork. This upgrade must be completed before 2026-08-25 03:00:00 UTC on Mainnet.

The hardfork changes execution semantics, and nodes that do not upgrade before activation may stop syncing or diverge from the network.

This release includes RPC correctness fixes, improved database performance, and optimizations to historical state lookups. During the maintenance window, brief interruptions to RPC availability may occur.
