On July 22, 2026, an attacker used unauthorized access to the upgrade authority of its BNB Chain staking contract to drain 8.59 million B2 tokens (about $3.86 million), which were sold and routed through cross-chain services reportedly toward Zcash. The team suspended staking, pledged full compensation to stakers and offered a 10% bounty with legal immunity; no attacker has been identified, and reports that the exploiting wallet had held privileged access since 2025 have raised unverified questions about insider involvement.","sections":[{"content":"B-Squared Network is a Bitcoin Layer-2 founded in 2022 (November 2022 per one source) and headquartered in Singapore. It describes itself as the first EVM-compatible rollup based on zero-knowledge proof verification commitment on Bitcoin, secured by zero-knowledge proofs and Bitcoin's Taproot. Its components are B² Rollup, a fast low-cost execution layer; B² Hub, described on one page as a 'Layer-1.5' modular component using a Proof of Signal (PoSg) mechanism and on the other as a Bitcoin data availability layer; and MiningSquared, a Bitcoin mining pool product. The protocol supports DeFi, NFT, SocialFi and AI-agent applications. A Pulsar Upgrade in September 2025 reduced transaction finality to 150 milliseconds, and on the first TGE anniversary (April 30, 2026) the project announced a long-term 'B² 2048' roadmap focused on AI-driven Bitcoin utility, including payment infrastructure for AI agents.","heading":"Protocol Overview","sources":[{"url":"https://www.gate.com/learn/articles/what-is-bsquared--network-b2/8892","name":"What Is BSquared Network (B2) — Gate.com Learn","type":"other","credibility":2},{"url":"https://www.coingecko.com/en/coins/bsquared-network","name":"BSquared Network — CoinGecko","type":"other","credibility":2},{"url":"https://docs.bsquared.network/b2_tokenomics","name":"B² Network Tokenomics — Official Docs","type":"official","credibility":1},{"url":"https://coinmarketcap.com/cmc-ai/bsquared-network/what-is/","name":"What is BSquared Network — CoinMarketCap","type":"other","credibility":2},{"url":"https://coinmarketcap.com/cmc-ai/bsquared-network/latest-updates/","name":"BSquared Network latest updates — CoinMarketCap","type":"other","credibility":2}],"severity":"low"},{"content":"B² Network closed a seed round around January 2024.

The attacker had unauthorized access to the contract's upgrade authority, the administrative permission that governs how the contract can be rewritten. B² Network confirmed the incident on X: 'The incident involved unauthorized access to the staking contract's upgrade authority. As a precaution, $B2 staking has been temporarily suspended while we complete additional security reviews. The issue has been contained, and we do not expect any further impact.' Pages differ on when the team confirmed it: July 22 on one, July 23 on the other.\n\nThe attacker sold the tokens on BNB Chain for about 5,409 WBNB (about $3.01–3.11 million), losing an estimated $850,000 to price impact, at an average of about $0.35 per token against a pre-attack price of about $0.45. Coin68 reported that B2 fell about 30% after news of the exploit. Lookonchain traced the on-chain activity after the transfer to the attacker-controlled address.","heading":"July 2026 Staking Contract Exploit","sources":[{"url":"https://x.com/BSquaredNetwork/status/2080077286238454109","name":"B² Network Official Statement on Security Incident — X (Twitter)","type":"official","credibility":2},{"url":"https://mpost.io/b%C2%B2-network-suffers-3-86m-exploit-offers-attacker-legal-immunity-for-partial-refund/","name":"B² Network Suffers $3.86M Exploit, Offers Attacker Legal Immunity For Partial Refund — Metaverse Post","type":"news_article","credibility":2},{"url":"https://cryptoadventure.com/b%C2%B2-network-faces-3-86-million-token-drain-as-attacker-sells-8-59m-b2/","name":"B² Network Faces $3.86 Million Token Drain As Attacker Sells 8.59M B2 — CryptoAdventure","type":"news_article","credibility":2},{"url":"https://cryptocurrencyhelp.com/news/b2-network-hit-by-8-59m-b2-token-drain-worth-3-86m/","name":"B² Network Hit by 8.59M B2 Token Drain Worth $3.86M — CryptocurrencyHelp","type":"news_article","credibility":2},{"url":"https://www.coindesk.com/tech/2026/07/23/bitcoin-ethereum-linked-protocols-lose-usd35-million-in-multiple-attacks-hours-apart","name":"Bitcoin, Ethereum-linked protocols lose $35 million in multiple attacks hours apart — CoinDesk","type":"news_article","credibility":1}],"severity":"critical"},{"content":"After converting the stolen B2 to WBNB on BNB Chain, the attacker bridged the BNB proceeds to Ethereum, swapped them for ETH and USDT, and deposited the assets into NEAR Intents and HOT Protocol, cross-chain routing services.

Specter and other reports note that the exploiting wallet had been granted privileged access to the staking contract's upgrade authority since 2025, more than a year before the theft, and that permissions were revoked only after the theft. Specter alleged this may point to insider involvement; others described it as either possible insider action or severely inadequate key management. The insider claim is unverified and no attacker has been identified.\n\nCryptoSlate characterised the incident as a 'control failure' at the upgrade-authority level, distinct from the same-day bridge exploits. Reporting noted the absence of time-locked upgrades, multi-signature requirements or public disclosure of key management practices. A February 2024 Scalebit audit of B² Network's zkEVM identified issues of varying severity, but whether it covered custody of the staking contract's upgrade key is unclear, and as of July 24, 2026 the team had not published a formal post-mortem or an independent post-incident security review.","heading":"Key Management Failure and Alleged Insider Risk","sources":[{"url":"https://protos.com/defi-loses-35m-in-a-day-are-bounties-inviting-more-hacks/","name":"DeFi loses $35M in a day: Are 'bounties' inviting more hacks? — Protos","type":"news_article","credibility":2},{"url":"https://www.coindesk.com/tech/2026/07/23/bitcoin-ethereum-linked-protocols-lose-usd35-million-in-multiple-attacks-hours-apart","name":"Bitcoin, Ethereum-linked protocols lose $35 million in multiple attacks hours apart — CoinDesk","type":"news_article","credibility":1},{"url":"https://cryptoslate.com/two-ethereum-bridges-lose-31-7m-within-hours-as-third-protocol-halts-staking/","name":"Two Ethereum bridges lose $31.7M within hours as third protocol halts staking — CryptoSlate","type":"news_article","credibility":2},{"url":"https://mpost.io/b%C2%B2-network-suffers-3-86m-exploit-offers-attacker-legal-immunity-for-partial-refund/","name":"B² Network Suffers $3.86M Exploit, Offers Attacker Legal Immunity For Partial Refund — Metaverse Post","type":"news_article","credibility":2},{"url":"https://scalebit.xyz/reports/B%C2%B2-Network-zkEVM-Final-Audit-Report.pdf","name":"B² Network zkEVM Final Audit Report — Scalebit (February 2024)","type":"research","credibility":2}],"severity":"critical"},{"content":"B² Network suspended B2 staking, pledged to fully compensate affected stakers, and directed users wishing to unstake to submit requests through its official Discord, with verification expected within one business day.
