 Decentralized peer-to-peer lending protocol Onyx Protocol lost roughly $2.1 million in an <a rel="noopener noreferrer nofollow" title="exploit" href="https://thebittimes.com/tag/exploit.html">exploit</a> of a market with no liquidity that was deployed on Oct. 27.&nbsp;
 The Onyx Protocol hacker <a rel="noopener noreferrer nofollow" title="exploit" href="https://thebittimes.com/tag/exploit.html">exploit</a>ed a known bug, a rounding issue behind the popular CompoundV2 fork, explained blockchain investigator PeckShield soon after alerting about the hack that went unnoticed by the protocol.
