According to The Block, the decentralized stablecoin protocol Usual has collaborated with blockchain security company Sherlock to launch a bug bounty program, offering a reward of $16 million to find critical vulnerabilities in their code library. This bounty exceeds previous rewards set by Uniswap ($15.5 million), LayerZero Labs ($15 million), and Wormhole ($10 million). The Usual code library has undergone 20 audits, including a recent Sherlock audit competition, with no medium or higher-level vulnerabilities discovered. Only vulnerabilities deemed critical are eligible for the highest reward. Usual currently manages over $880 million in total value locked (TVL). Sherlock CEO Jack Sanford stated that this collaboration aims to promote the integrity of DeFi and enhance trust in the entire ecosystem.
