YZi Labs-backed BounceBit Chain to shut down after $3M exploit
Protos reported that BounceBit, a bitcoin restaking firm backed by YZi Labs, said it will shut down its blockchain after hackers exploited an authorization flaw and stole more than $3.1 million in BB tokens. BounceBit said attackers moved 286 million BB tokens from nine wallets between Aug. 19 and Aug. 20. It also said the attacker sent about 254 million BB tokens to one major crypto exchange, nearly 10 million to another exchange, and left 18.5 million BB tokens in a consolidated address. In a statement on X, the company said it had paused nodes and temporarily disabled BB transactions on the chain, while its CeDeFi app, smart contracts and vaults were not affected. BounceBit said it cannot carry out a normal network upgrade because the chain is built on discontinued Evmos infrastructure. Instead, all BB tokens except those tied to the attacker will be reissued as BEP-20 tokens on BNB Chain based on a snapshot taken before the exploit. The company also said it has asked exchanges to freeze specific addresses, and told token holders they do not need to take action but should watch out for scammers. Protos added that BounceBit raised $6 million in a 2024 seed round co-led by Blockchain Capital and Breyer Capital, and that YZi Labs later invested in April 2024, according to Binance Square moderator Tang Hua.
