# Code4rena Code4rena (C4) is a competitive audit and bounty platform where security researchers, referred to as [Wardens](/roles.md), review, audit, and analyze codebases for security vulnerabilities in exchange for bounties provided by sponsoring projects. The players in the arena: * [**Wardens**](/roles.md) protect the DeFi ecosystem from threats by auditing code. * [**Sponsors**](/sponsors.md) create prize pools to attract wardens to audit their project. * [**Judges**](/roles/judges.md) decide the severity, validity, and quality of findings and rate the performance of wardens. ## How Code4rena works These docs provide detailed information and guidelines for current and potential community members, and aim to answer the most frequently-asked questions about how Code4rena — and our competitive audits — work. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
