Scheduled

We are upgrading our Base Sepolia Testnet infrastructure to v1.1.0 ahead of the Beryl hardfork, scheduled for June 18 at 18:00:00 UTC. This is a required upgrade to maintain compatibility with the network following the hardfork. During the maintenance window, brief interruptions to RPC availability may occur.

No RPC-breaking changes are included in this release.
