Code4rena company
Overview
Code4rena (C4) is a competitive audit and bug bounty platform for smart contract security. Security researchers, called Wardens, review and audit sponsored codebases in exchange for a share of a reward pool: a sponsor puts up the pool, Code4rena hosts the competition and the code, and anyone registered as a Warden can hunt for bugs. Judges then assess findings for validity and severity, and a public audit report compiling valid findings is typically published on the Code4rena site for the benefit of the project's users and the wider Web3 security community. The platform reports a community of over 10,000 auditors, with an average of 100+ security researchers participating in each audit — a breadth-of-review model that differs fundamentally from engaging a single audit firm. Code4rena was founded and launched in 2021 and is based in Liberty Hill, Texas. It also offers private audits alongside open competitions. Code4rena launched in 2021 as a competitive-audit marketplace. It was acquired by security firm Zellic in August 2024, and since June 2025 has run all competitive contests at a 0% platform fee while remaining the largest warden pool in the sector.
