    Audit contest calendar FAQ

    Where can I find upcoming smart contract audit contests?

    Choose Upcoming to see announced competitions with a published start date. Compare overlapping audits in the timeline, or use the list to sort by start date, deadline or reward. Availability depends on what each platform publishes.

    How do I find Solidity or Rust audit competitions?

    Use the Language filter to find contests matching your skills, including Solidity, Rust, Move and other languages when the platform publishes them. The calendar also includes security challenges beyond smart contracts; the Type filter separates challenges from audit contests.

    Are audit contests the same as bug bounties?

    An audit contest usually has a fixed review window and a defined code scope. A bug bounty is generally an ongoing program. BBRadar uses each platform’s program classification to keep ordinary bounties out of this contest calendar. Rewards follow the platform’s rules; a published maximum is not always a shared prize pool.

    Is the Web3 audit calendar free to use?

    Yes. Browsing the calendar, comparing public schedules and rewards, and downloading available calendar events are free. Full target inventory, scope exports and program intelligence remain part of BBRadar Pro.

    Why does a contest show an unconfirmed date?

    Dates to confirm means BBRadar has not yet verified a complete, consistent schedule. The source may not publish a date, or a recent change may still be waiting for a successful refresh. A date can already be visible on the platform before it reaches BBRadar. Check the official contest page for the current deadline; the calendar does not invent missing dates or closing times.

    Can I add audit contest deadlines to my calendar?

    Export calendar downloads an ICS file for matching live and upcoming contests with exact start and end times. Import it into Google Calendar, Apple Calendar or Outlook. Times are in UTC; date-only deadlines stay labeled and are excluded from timed exports. Downloads are snapshots, so check the official contest page for schedule changes.
