Certification (ID verification)

Certifying your identity (also known as ID verification, or KYC) is an optional step for warden accounts that — along with your signal score — unlocks privileges including higher submission limits and post-judging QA comments.

• Identity verification status can be viewed on your C4 account screen.

• If KYC is required, a C4 staff member will reach out to you directly to coordinate.

• Self-serve ID verification was removed on May 28, 2026.

In the event that a certified contributor violates or is believed to have violated the Terms of Service, Code4rena reserves the right to pursue all remedies available, including removal from the platform or legal action.
