🚨 AN EXPLOIT JUST KILLED AN ENTIRE L1

BounceBit is permanently shutting down its standalone blockchain after a protocol-level authorization vulnerability allowed an attacker to move roughly 286.5 MILLION BB.

And here’s what makes this incident unusual:

🔓 No private keys were stolen
✍️ No signatures were forged
💰 Roughly $3M in BB was moved
⛓️ BounceBit L1 → permanently shutting down
🟡 BB → migrating to BNB Chain

The team plans to restore legitimate balances from a pre-attack snapshot, while excluding the attacker-controlled 286.5M BB from the new supply.

This isn’t just another exploit followed by a patch.

The exploit effectively ended the blockchain itself.

BounceBit says rebuilding its Evmos-based chain no longer makes sense, especially after Evmos was discontinued earlier this year. Most of its products and users already operate around BNB Chain infrastructure.

There’s a bigger lesson here for crypto.

Launching your own L1 gives a project control over its infrastructure.

It also means you own the infrastructure risk.

Sometimes the strongest response to a security failure isn’t rebuilding everything.

It’s admitting another chain can provide better infrastructure.

BounceBit chose migration over resurrection.
