Frequently Asked Questions
How does competitive auditing work?
You post your code and a prize pool. Wardens compete to find bugs during a fixed period. Prizes are awarded based on severity and uniqueness of findings.
Is this better than traditional audits?
It's complementary. Competitive audits provide breadth (many eyes) while traditional audits provide depth (thorough analysis by experts).
How are findings evaluated?
Experienced judges review all submissions, deduplicate findings, assess severity, and determine prize allocation.
