Standard — Berachain Mainnet - Upgrade BeaconKit and bera-reth to v1.4.0

Scheduled for Jun 15, 00:00 - 04:00 UTC

Scheduled

The Berachain Network is undergoing the Fusaka (Fulu) hard fork on June 24, 2026 at 16:00:00 UTC. We are upgrading our Berachain Mainnet infrastructure to BeaconKit v1.4.0 and bera-reth v1.4.0 ahead of this activation. Nodes not upgraded before this time will diverge from the canonical chain. Brief interruptions to RPC availability may occur during the upgrade window.

No user-facing RPC changes are included in this release beyond hard fork activation.
