Leading crypto projects choose Code4rena.

There's a reason why.

Don't just take our word for it.

One of the things I enjoy most about competing on @code4rena is getting to read lots of code and see new techniques in the wild.


We greatly enjoyed our @code4rena experience - here's why it is the best value in auditing: quick spin-up time, flexible bounty awards, open nature means more eyes on your code, by our count ~10x more vs traditional audit shops, helpful community of wardens and judges


After grinding for 14 months I finally reached my goal of being the first to cross 1M$ on the @code4rena leaderboard. Thanks to everyone involved, this has been very fun, lucrative, and I learned a lot by seeing other wardens' vulnerabilities that I missed.
