What all sources agree on
- BounceBit is shutting down its L1 blockchain (BounceBit Chain).
- BB tokens will be reissued as BEP-20 tokens on BNB Chain.
- The exploit stemmed from an authorization flaw in a native Evmos module used by BounceBit Chain.
- Attackers moved roughly 286 million BB tokens out of nine accounts without authorization.
- The reissue will be based on a pre-exploit snapshot, excluding the attacker's tokens.
- BounceBit's CeDeFi, Prime, and RWA products were reported unaffected by the exploit.

What would settle it: BounceBit's official post-mortem report or on-chain transaction data showing the BB token price at the time of the transfers.
What to make of it
Treat the shutdown, migration to BNB Chain, and the roughly 286 million BB tokens moved from nine accounts as established; the dollar value of the exploit ranges from about $3.1 million to $286.5 million across reports and should not be treated as settled until BounceBit or an on-chain analysis clarifies the token's price at the time of the attack.
