what's Code4rena?
Code4rena is a community-driven platform that facilitates competitive smart contract audits for blockchain projects, particularly in DeFi and NFTs. It operates as a security marketplace where independent security researchers, known as "wardens," compete to identify vulnerabilities in submitted codebases during timed contests. Projects sponsor these audits with prize pools, rewarding findings based on severity, and the process helps enhance protocol security before mainnet launches. The platform has audited code for major ecosystems like Chainlink, zkSync, and Optimism, fostering a freelance market for auditors while providing thorough, crowdsourced reviews. The project is backed by investors like Paradigm and integrates with the broader Web3 security landscape. It emphasizes transparency and efficiency in audits, differing from traditional firm-based reviews by leveraging competition to uncover more issues. Code4rena also supports DAO governance and has its own token, ARENA, which incentivizes participation and aligns stakeholders in the security ecosystem.
Code4rena prevented 286 high/medium severity vulnerabilities from entering production in 2025.
