BounceBit abandons its Layer 1 after 286.5M BB exploit – Why BNB Chain?
YZi Labs-backed BounceBit has introduced plans to completely stop its BounceBit Chain. As a substitute of repairing the community, BounceBit plans to redeem BB as a BEP-20 token on BNB Chain.
This comes after a latest assault by which the wrongdoer misused a flaw in one in every of BounceBit Chain’s built-in protocol modules. This allowed the attacker to maneuver BB tokens from 9 strange mainnet accounts with out getting permission from the account house owners.
BB compromised
The attacker moved roughly 286.5 million BB via 14 transactions over roughly 5 hours. The protocol did not confirm whether or not the debited account had licensed every transaction.
Because of this, the attacker may identify one other account because the funding supply and switch its BB with out permission.
BounceBit halted the blockchain to include the exploit. No additional unauthorized transfers occurred afterward.
Nonetheless, the vulnerability uncovered a deeper drawback than one faulty module.
The principle driver of the assault
Now, speaking concerning the purpose behind the whole shutdown is that BounceBit Chain was constructed on the Evmos stack, which included a vesting and lockup module.
For these unaware, Evmos itself has been discontinued. Subsequently, merely doing the patchwork to repair the vulnerability and restart the community was not adequate to keep away from additional such assaults.
Transferring our fork onto a successor codebase would due to this fact not be a standard improve, however a considerable re-platform requiring a full rebuild, re-audit, and revalidation earlier than it may safely carry person belongings once more.
That stated, BounceBit has lots of its merchandise already working on BNB Chain, the place person exercise is more and more concentrated. By relocating BB there, the mission could have rather more issues to supply together with “mature safety, deeper liquidity, and pockets assist.”
So moderately than spending important assets rebuilding its personal Layer 1, BounceBit believes it’s safer and extra environment friendly to consolidate round BNB Chain.
Is BounceBit the primary trade to close down?
As of now, BounceBit has requested exchanges to freeze related funds whereas avoiding blanket freezes that would have an effect on harmless customers. Moreover, in addition they plan to revive person balances utilizing the pre-attack snapshot, as an alternative of relying on recovering the stolen tokens.
Properly, this isn’t the primary trade that has been shut down. In accordance with AMBCrypto’s latest report, about 9 exchanges and buying and selling platforms have been shut down in 2026. However curiously, it’s the lowest annual rely in a minimum of eight years.
Last Abstract
- Within the BounceBit assault, BB tokens from 9 strange mainnet accounts had been moved with out permission.
- The trade has deliberate to relocate its BB on the BNB Chain, the place there’s elevated focus of person exercise.
