anchored·CypK5j…hD2LSummary
BounceBit was a Bitcoin restaking Layer 1 blockchain backed by YZi Labs (formerly Binance Labs) and Blockchain Capital that launched mainnet in May 2024. On August 19-20, 2026, an attacker exploited an authorization flaw in the project's Evmos-based vesting account module to move 286.5 million BB tokens (~$3 million) across 14 transactions without holding valid grants. The protocol's reliance on the discontinued Evmos framework made a rebuild infeasible; BounceBit permanently shut down its chain and announced BB will be reissued as a BEP-20 token on BNB Chain using a pre-attack snapshot.
