B² Network Attacked on BNB Chain: $3.86 Million Stolen and Bridged

The Layer 2 scaling solution B² Network has reportedly suffered a significant security breach on the BNB Chain. On July 23, 2026, on-chain monitoring tools and analysts identified suspicious activity involving the unauthorized extraction of millions of native tokens. Initial reports suggest that the exploiter managed to siphon funds and initiate a complex laundering process across multiple blockchain protocols to obscure the trail of the stolen assets.

Details of the B² Network Exploitation

According to data provided by on-chain analyst Specter, the attacker successfully seized 8.591 million B2 tokens, which carried an estimated market value of 3.86 million USD at the time of the incident. Following the initial theft, the perpetrator quickly moved to liquidate the assets to prevent freezing by the project's developers or centralized exchanges.

• The attacker converted the B2 tokens into 5,409 WBNB (Wrapped BNB).
• The value of the converted WBNB was approximately 3.11 million USD due to slippage and market volatility during the swap.
• The assets were then moved from the BNB Chain to the Ethereum mainnet via cross-chain bridging protocols.

Asset Movement and Privacy Protocols

The security breach has highlighted the sophisticated methods used by modern hackers to bypass traditional tracking. After reaching the Ethereum network, the stolen funds were redirected toward the NEAR Protocol through NEAR Intents, a cross-chain communication framework. The final destination for the funds appears to be Zcash, a privacy-centric cryptocurrency that utilizes zero-knowledge proofs to mask transaction details.

The funds are currently being transferred to Zcash via NEAR Intents, making the recovery process significantly more complex for investigators.

This transition into privacy coins like Zcash is a common tactic used by malicious actors to break the deterministic link between the source of the theft and the final payout.

Current Status and Security Implications

As of the latest updates, the B² Network team has not officially released a detailed post-mortem regarding the specific vulnerability exploited—whether it was a smart contract flaw, a private key compromise, or a logic error in the bridge. Investors and liquidity providers are advised to monitor official channels for potential updates on compensation plans or network restarts.

The incident underscores the persistent risks associated with cross-chain interoperability and the speed at which capital can be moved across decentralized finance (DeFi) ecosystems. The integration of privacy protocols like Zcash and the use of the NEAR ecosystem as a conduit further demonstrates the evolving technical landscape of cryptocurrency-related security threats.
