Bera-Reth v1.4.4

Summary

On v1.4.3, --txpool.minimum-priority-fee can be bypassed. reth's built-in filter exempts legacy and EIP-2930 transactions and checks the declared fee cap rather than the tip actually paid, so a spammer can fill the pool while tipping the proposer close to nothing.

v1.4.4 re-applies the effective-tip enforcement from v1.4.2 (#270), reverted in v1.4.3 (#275). The floor now covers every transaction type, measured against the effective tip at the next-block base fee.

Contains the same Osaka1 mainnet activation as v1.4.3, unchanged at 1785945600 (August 5, 2026 at 16:00:00 UTC). Upgrading does not change your fork configuration.

Upgrading

Already on v1.4.3? The binary is the only change. Skip the rest of this section.

Coming from v1.4.2 or earlier, this release also carries the Osaka1 mainnet fork:

• Nodes on the built-in mainnet preset need nothing beyond this binary. That covers both --chain mainnet and omitting --chain, since mainnet is the default.
• Nodes passing an explicit genesis file must also refresh it, from beacon-kit#3152 or directly (~47 MB): https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80094/eth-genesis.json. Upgrading the binary alone is not enough. A stale file leaves the fork unscheduled with no error, and the node halts at activation.

No beacon-kit upgrade is required, Osaka1 is EL-only. Verify with:

Berachain Osaka1 configuration: {time=1785945600, min_base_fee_wei=1000000000, min_blob_base_fee_wei=1000000000}
