Launching Private Competitive Audits: Top Warden Reviews of Unpublished Protocol Code
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.In some cases, a fully public audit isn’t a great fit:Stealth startupsTop secret NFT launchesCompanies who closely guard IP and trade secretsProjects sensitive to creating a public record of past vulnerability patternsAnyone worr...

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...
Code4rena competitive audits find more bugs faster than any other method.

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 Wardens from the Code4rena community in a format that best suits their needs.
When a Versus competition is announced, the highest-ranking wardens who RSVP within a 48-hour window will be able to participate in the audit.
If the Sponsor has already run an open C4 audit, then a portion of the RSVPs will be offered to top-performing Wardens from that previous competition. The remaining RSVPs (if any) will be offered to the highest-ranking Wardens on the global leaderboard.
If the Sponsor hasn’t already partnered with C4, then RSVP spots are offered to the highest-ranking Wardens on the global leaderboard.
The number of Wardens involved in Versus competition changes depending on the audit scope but ranges between 3 - 8.
But isn’t the whole point of Code4rena to get as many eyes on the code as possible?
Absolutely! But we’re also aware that some projects have tight budgets—especially in a bear market. A Versus Competition allows for the rigorous review of a Code4rena audit with a smaller set of participants.
We’re really excited about this new introduction from both a Sponsor and Warden perspective: Sponsors now have increasing customization options to create an audit competition perfect for their project, and Wardens now have more incentive to perform at the top of their game in the hopes that they will be offered additional opportunities.
Get started
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— of any category —drop us a line. We can spin up an audit within 48 hours.
