Bera-Reth v1.4.0

on GitHub

Summary

This is the mainnet-ready release for the Fusaka hard fork. It enables the Osaka EIPs (BRIP-10) on Berachain and migrates EIP-6110 deposit handling to the native Berachain deposit event, on top of Reth v1.11.4.

Berachain mainnet Fusaka activates Wednesday, June 24 2026 16:00:00 UTC (unix 1782316800). Bepolia (testnet) Fusaka activated on May 27 2026 16:00:00 UTC (unix 1779897600).

All mainnet operators must upgrade to v1.4.0 before the activation timestamp. Nodes running older versions will diverge from the canonical chain at the fork.

New features:

• Enabled Osaka EIPs (BRIP-10) and scheduled the Fusaka hard fork for Berachain mainnet (#243, #255)
• Switched EIP-6110 deposit parsing to the Berachain deposit event (#226)

Critical bug fixes:

• Preserve EIP-4844 sidecars in the engine and txpool across the Osaka transition (#248)
• Replace engine_getPayloadV5 panic with an UnsupportedFork response (#247)
• Return the correct V4P11 engine response envelope and handle Prague3 payloads (#239)
• Adjust deposit contract address returned by eth_config (#246)
• Forward transaction origin from RPC instead of hardcoding Local (#240)

Maintenance & security:

• Bumped reth from v1.11.3 to v1.11.4 (#249)
• Enforced Prague1 validation in beacon consensus (#250)
• Hardened CI: pin actions to SHA, scope Docker digest artifacts, fix cargo deny (#254, #253, #241)

Update Priority

This table provides priorities for which classes of users should update particular components. This is a mandatory hard fork; all operators must upgrade before the mainnet activation timestamp above.
