The Clipper decentralized exchange (DEX) experienced a security incident at 4 AM UTC on December 1, targeting liquidity pools on Optimism and Base.

- Chaofan Shou, co-founder of the security company Fuzzland, initially believed the attack was due to a private key leak, allowing the attacker to authorize deposit and withdrawal transactions. However, Clipper denied this, asserting that their security model is designed to prevent such issues.

- The attack caused damage of approximately $450,000, accounting for about 6% of Clipper's total value locked (TVL). Other attack attempts were unsuccessful.
