Code4rena

Code4rena is the leading smart contract security marketplace, revolutionizing Web3 security through competitive audits. Founded as a DAO for Web3 security, Code4rena invented the competitive audit format that has disrupted the smart contract security industry.

Core Services

Code4rena operates two primary audit offerings:

Competitive Audits: The flagship service that brings together 100+ security researchers to compete in finding vulnerabilities in smart contracts. Each audit attracts an average of 70+ professional auditors who compete for bounties based on the severity and rarity of vulnerabilities discovered. This crowdsourced approach achieves half a year's worth of code review in just one week, with projects able to start audits in as little as 48 hours.

Zenith: A premium audit service that assembles proven, elite auditors with track records to provide deep analysis and consultative security reviews. Zenith offers fast turnaround times (less than 24 hours to start) with experienced security researchers across multiple blockchain ecosystems including EVM, Solana, Move, Cairo, Cosmos, and Zero-Knowledge proofs.

Bug Bounties: Ongoing security programs that provide continuous vulnerability discovery for live protocols, with bounties ranging from $25,000 to $250,000 in USDC.

Key Strengths

Code4rena has secured over 500 audits across major DeFi and NFT protocols, uncovering 1,607+ unique high-severity vulnerabilities and 26,898 total unique findings. The platform maintains a community of 16,600+ registered security researchers (called "Wardens") who compete on the most trusted competitive audit platform in Web3.

The competitive model incentivizes diverse talent to break code and find vulnerabilities that traditional single-firm audits miss. With industry-defining leaderboards and fairest judging practices, Code4rena attracts both proven security talent and rising stars, providing unprecedented breadth and rigor.
