Summary

UniLend V2 is a permissionless DeFi lending and borrowing protocol deployed on Ethereum mainnet in February 2024, designed to support all ERC-20 tokens via isolated dual-asset pools. On January 12, 2025, the protocol suffered a smart contract exploit that drained approximately $197,000 from its stETH pool due to a logic flaw in health factor calculations during the asset redemption process. Despite having been audited by PeckShield and SlowMist prior to launch, the exploited vulnerability was not caught or fully remediated, and as of the last available reporting the attacker's 20% bounty offer had not yielded a fund recovery.
