A look at Code4rena audits: Open
Traditional audits take too much time and are limited in terms of talent and depth. Bug bounties don’t keep bugs out of production. That’s where Code4rena comes in: a high-performance competitive audit platform that rewards keeping rare, high-risk bugs out of production. Don’t just take our word for it either: OpenSea, ENS, Sushi, and PoolTogether are just a few of the projects that have run audits with C4. So, how do Code4rena audit competitions work?

Major Code4rena upgrade eliminates work for audit contest sponsors
We're excited to share a huge improvement we've made to Code4rena based on input from builders: New audits booked with Code4rena will include deduplication of all incoming bugs from your project’s audit contest so your team doesn’t have to stop building. Run an audit contest and you’ll get back fully triaged issues one week from contest end date. The enormous increase of participation in Code4rena contests has been overwhelming. That’s a great problem to have! Buuuut still a problem...

A look at Code4rena audits: Versus
Code4rena is famous for running public audit competitions that incentivize the largest amount of auditors to compete in finding the rarest bugs. Sometimes though, projects are looking to run a small and focused audit with just a few wardens to fit within budget constraints that might otherwise rule out a competitive audit. The solution: Versus competitions. So how do Versus audits work? With the introduction of Versus competitions, we’re giving Sponsors the opportunity to work with top Warden...
Code4rena competitive audits find more bugs faster than any other method.

With an unmatched level of code review and on-demand access to top-tier security experts, Code4rena’s competitive audits have become a critical piece in the web3 security stack, but the public nature of these audits occasionally poses a challenge for certain projects.
Stealth startups
Top secret NFT launches
Companies who closely guard IP and trade secrets
Projects sensitive to creating a public record of past vulnerability patterns
Anyone worried about getting contract deployments front-ran by competitors
Projects in need of frequent, incremental audits for small updates and upgrades
These constraints lead some projects to hire a private firm, or even forgo audits altogether. Even more costly, the need for privacy often forces organizations to engage in multiple rounds of audits from larger firms, compounding their scheduling challenges and shipping delays.
Fortunately, Code4rena competitive audits ensure more rigorous, faster coverage than traditional audits, at a relatively reduced cost. And now, we’re thrilled to offer a new product for teams that require more privacy.
Today, we’re excited to introduce Code4rena Classified: private competitive audits.
Code4rena Classified audits offer:
Flexible privacy options based on your needs
Same competitive audit model
Same time to market — can start within 48 hours
Similar fee structure to public competitive audits
Yes, our public audits allow anyone to show up and compete just by providing an address for awards. But we are now rolling out open access to sponsors to create new competitive audits featuring wardens who have met the conditions of our Certified Warden program.
Every Certified Warden has:
Agreed to our Certified Contributor Agreement which includes non-disclosure terms
Agreed to our Code of Professional Conduct, which holds wardens to high ethical standards
Completed a formal ID verification process
Established themselves as a positive contributor and maintained good standing in the Code4rena warden community
We've already trialed and had great success with Certified Wardens. If you followed along with our OpenSea Seaport audit, you've seen them in action. Every warden who received awards completed the certification process, leading to higher-quality submissions.
Today, more than 170 of Code4rena’s most proven wardens can deliver on Private Competitive Audits.
With Code4rena Classified, C4 can now deliver privacy based on your needs:
Want to maximize the amount of participation but keep your name and results secret pre-launch? Code4rena can promote a [NAME REDACTED] audit publicly and require all participants to be Certified Wardens to access your code.
Want to run a private contest to keep your launch stealth and embargo the audit report until you're ready to include it in launch materials? We've got you covered.
Want to keep everything private about your audit, including the findings and the report? We can invite Certified Wardens only and deliver your report privately and confidentially.
This is a major addition to the Code4rena audit platform and we are excited about the opportunities private competitive audits offer to both stealth projects and top wardens eager to review fresh code.
Code4rena has audited projects including OpenSea, ENS, Sushi, PoolTogether, Connext, BadgerDAO, NFTX, and Slingshot.
When you’re ready for a competitive audit of your project—public or private—drop us a line in Telegram or Discord. We can spin up an audit within 48 hours.
