$20M EXPLOIT CRIPPLES SONNE FINANCE, HACKER IN NO MOOD FOR NEGOTIATION

Summary from the TLDR Crypto newsletter

Sonne Finance, a decentralized money market on the Optimism L2, has been exploited for $20 million. Sonne offered a 10% bounty to the hacker if the funds were returned, but the money is already being moved to other addresses. The hacker took advantage of a known bug in Compound V2, which Sonne forked for its protocol.
