Internet reports that the decentralized stablecoin protocol Usual has partnered with blockchain security company Sherlock to launch a vulnerability bounty program, offering a reward of US$16 million for finding key vulnerabilities in the code base. The bonus exceeds previous bonuses established by Uniswap($15.5 million), LayerZero Labs($15 million) and Wormhole($10 million). The Usual code base has undergone 20 audits, including the most recent Sherlock audit competition, but no medium-or higher-level vulnerabilities have been found. Only vulnerabilities identified as critical are eligible for the highest reward. Usual currently manages more than $880 million in total locked value (TVL).
