Balancer DAO has issued a final appeal to the hacker responsible for a $100 million exploit, urging the return of stolen digital assets. The decentralized exchange posted an onchain notice offering a bounty for the return of funds by Saturday, warning of potential "technical, onchain, and legal measures" if the offer is ignored. The hack, involving staked Ether and other tokens, exploited vulnerabilities in Balancer's V2 Composable Stable Pools. Despite audits by four security firms, the breach highlighted flaws in the platform's smart contracts. Balancer initially proposed a bounty of up to 20% of the stolen amount, but no response has been received.
