Code4rena is the leading smart contract security marketplace, run by a 25-person team operating remotely. We invented the competitive audit, incentivizing thousands of security researchers on our platform to compete to find more rare, high-severity vulnerabilities than any other model. Code4rena audits differ from traditional audits and bug bounties by offering protocols wider coverage and guaranteed payouts for participants. DeFi and NFT Industry leaders like zkSync, ENS, Chainlink, and Opensea have enlisted Code4rena's help to secure their protocols and go to market faster. Code4rena offers the ability to start an audit in just 48 hours, a timeline unheard of in a field where the top audit firms are booked out four to six months in advance. So far over 950 high severity vulnerabilities have been found across 280 audits with more than 70 professional auditors participating in every contest on average.
