# Restricted competitions and C4 mitigation reviews

Some C4 competitions are limited to specific participants. For the most part, these are mitigation reviews to review the fixes from a preceding C4 competitive audit. 

Participation in these competitions is determined by [RSVP in the Code4rena Discord](https://discord.com/channels/810916927919620096/958800160870240286). Each opportunity outlines how the opportunity will be assigned (e.g. "The 3 highest ranking wardens based on the audit results who RSVP by the end of the claim window get the opportunity," etc.). 

The code repo and competition details for restricted competitions are private to the participating wardens, judge, and sponsor team only.<br>
