BounceBit’s August security incident has resulted in permanent retirement of the project’s original blockchain.
Exchange guidance says BB support is migrating to BNB Smart Chain on a 1:1 basis while spot, margin, futures and Earn remain available.
That means the token can survive economically while the original execution environment disappears.
For exchange users, the migration can be handled centrally. Self-custody users face a more complex risk: old-chain application state, smart-contract positions, NFTs and unsupported assets do not automatically migrate just because the native token has a 1:1 replacement.
The event remains Critical because permanent L1 retirement is a structural consequence of the hack.
