Bepolia activated the Fusaka/Fulu hard fork at 2026-05-27 16:00 UTC (unix
1779897600), which ships new EVM-inflation-withdrawal values. beacon-kit
v1.3.4 (pre-fork) crash-loops replaying the fork-boundary block 20513284:
'first withdrawal is not the EVM inflation withdrawal' (RestartCount 3742 on
us-41). The EL (bera-reth v1.4.0) already speaks the Fusaka engine API
(newPayloadV4P11 etc.) and accepted the post-fork block, so only the CL is
behind. v1.4.0-rc3 sets the Fulu fork time + new inflation values. Applies
to all berachain chains' beacon-kit default; only bepolia is deployed.
