UNCX Vesting Bug Led to $1.49 Million Gross Drain Estimate

UNCX’s Vesting V2 bug let positions claim more of shared token pools than their recorded stakes justified, bringing the estimated gross amount drained to $1.49 million across four chains by Oct. 15. The first successful Ethereum drain occurred Wednesday, Oct. 14, at 11:49:59 a.m. ET (15:49:59 UTC). By 2:19 a.m. ET (06:19 UTC) Thursday, Oct. 15, the estimate included 11 drain transactions across Ethereum, BNB Chain, Robinhood Chain and Base. Rounded amounts were $969,000 on BNB Chain, $242,000 on Ethereum, $169,000 on Robinhood Chain and $114,000 on Base. The cross-chain figure followed the initial Ethereum pool drain of about $86,000 in one transaction . The incident affected 10 tokens. UNCX’s liquidity-locking contracts and legacy vesting contracts were outside the affected scope.
