Decentralized finance (DeFi) lender bZx suffered a hack of reportedly $55 million, according to a tweet on Friday by the blockchain security firm SlowMist.
- “#bZx private key compromised, over $55 million dollars stolen so far. We’ll continue to update as more information is discovered,” SlowMist tweeted.
- bZx responded in a tweet that a private key controlling the protocol’s deployment on Polygon and Binance Smart Chain was compromised, but that its smart contracts were not.
- The protocol added that about 25% of the stolen amount was “personal losses from the team wallet that was compromised,” and that the incident is still under investigation.
- bZx suffered three hacks last year, although it was able to recover $8 million in cryptocurrency from the third and largest of these attacks, which occurred in September. The other two hacks for $630,000 and $350,000, respectively, occurred in February.

Important to note: the bZx smart contracts themselves were not compromised. This incident only impacted the Polygon and BSC deployments via a compromised key.
