BNB Chain issued dual security communications in early November 2026, urging operators of the BSC-Reth execution client to apply an immediate software update and renewing attention on its Red Alarm service that identifies potentially hazardous decentralized applications and smart contracts.

The notices address separate layers of the network. One targets infrastructure operators responsible for processing and validating blockchain data. The other provides wallet users with information intended to support decisions before interacting with applications or contracts.

BSC-Reth Operators Instructed to Install Hotfix

On November 6, BNB Chain advised all BSC-Reth operators on both mainnet and testnet to install version 0.1.4-hotfix and restart their nodes without delay. The recommendation applies to validators, block builders engaged in maximal extractable value activities, full-node operators and sentry operators.

According to the release notes, the patch corrects an error that could cause the Reth client to compute an incorrect state root under certain conditions. A state root is a cryptographic summary of account balances, contract storage and other elements of network state that nodes use to confirm consistency of data.

The correction incorporates a fix from the upstream Reth project related to a legacy calculation path. Operators are not required to perform a database migration or execute a hard fork to apply the update. Installation followed by a restart is sufficient.

BNB Chain stated that the exposure affecting BSC-Reth was limited. It also clarified that opBNB does not rely on the related op-reth client and therefore is not impacted by the issue.

Red Alarm Tool Receives Renewed Promotion

In a separate November 7 communication, BNB Chain directed users to the Red Alarm list maintained through its DappBay service. The tool flags decentralized applications and smart contracts that meet potentially risky criteria, allowing users to review warnings before connecting wallets or completing transactions.

Visitors can browse entries by category, blockchain, risk factor and listing date. Common alerts include inaccessible project websites, which may result from shutdowns or other causes, as well as suspected Ponzi-style structures or contract features that could lead to user losses. The service also offers a scanner for checking individual smart contracts or wallet addresses.

Red Alarm is not a new initiative. BNB Chain introduced it through DappBay in July 2022. An update the following month reported that the system had already examined more than 3,300 contracts and identified over 50 projects presenting risks. Assessments rely on automated scans, models and available contract data. The platform cautions that its ratings are informational only and should not replace independent verification by users.

BNB Chain described the service as part of continuous efforts to support user safety, noting that it supplies additional context for decisions involving decentralized applications.

Separate from Upcoming Jenner Upgrade

The client hotfix is distinct from the previously scheduled Jenner hard fork. That upgrade is set for December 8, 2026, at 02:30 UTC and introduces independent network changes, including the Payment Lane proposal. The feature reserves a default 5 percent of each block’s gas capacity for eligible payments, aiming to maintain space for approved transfers even when other transactions compete for capacity.

The two November notices were not presented as responses to a single security incident. One focuses on software used by node operators, while the other assists end users evaluating applications. Together they form part of BNB Chain’s broader activity around network security and infrastructure readiness.
