BNB Chain Releases BSC-Reth v0.1.4 Hotfix for Wrong State Root Bug
The client patch fixes an upstream Reth flaw, needs no hard fork or database migration, and applies to BSC mainnet and testnet nodes.
Key Takeaways
- BNB Chain published the BSC-Reth v0.1.4-hotfix on November 6, 2026 and recommends every node operator upgrade and restart.
- The patch fixes an upstream Reth flaw that could make the client compute the wrong state root under specific conditions.
- No hard fork and no database migration are needed to apply the fix.
- The Jenner hard fork on BNB Chain is scheduled for December 8, 2026 at 02:30 UTC.
BNB Chain, the network behind BNB (BNB), released the BSC-Reth v0.1.4-hotfix on November 6, 2026, and told every BSC-Reth node operator on mainnet and testnet to install it and restart. The patch fixes an error that could make the client compute the wrong state root under specific conditions.
What the BNB Chain BSC-Reth Hotfix Changes
A state root is a cryptographic summary of account balances, contract storage and other network state. Nodes use it to check that they agree on valid data. The bug fixed in v0.1.4-hotfix could make Reth calculate that summary incorrectly along a legacy calculation path. The release pulls in the correction from the upstream Reth project. Operators need no database migration and no separate hard fork. The required action is an installation followed by a restart.
Who Needs to Install v0.1.4
The upgrade recommendation covers all reth-bsc node operators on BSC mainnet and testnet: validators, maximal extractable value block builders, full node operators and sentry operators. Ordinary wallet users do not run node software. BNB Chain said the exposure on BSC-Reth was limited and that opBNB does not use op-reth, the related client named in the wider Reth security discussion. Other EVM networks running Reth-based clients shipped similar fixes this week.
Red Alarm Flags Risky Apps for Users
On November 7, BNB Chain also pointed users to Red Alarm, the risk scanner inside its DappBay service, live since July 2022. Red Alarm flags decentralized applications and smart contracts that meet potentially risky conditions and lets visitors scan a contract or wallet address before they connect. The listings draw on automated scans, models and available contract information.
The Jenner Hard Fork Is Set for December 8
The hotfix follows a November 3 BSC-Reth update that scheduled the Jenner hard fork for December 8, 2026 at 02:30 UTC. Jenner includes a Payment Lane change that reserves a default 5% of each block's gas capacity for eligible payments. That upgrade carries its own compatibility deadline for mainnet node operators on the BNB Chain ecosystem. Traders can follow the market reaction on the BNB price chart. BNB Chain remains one of the busiest layer 1 blockchains by transaction volume.
