Pick winners your audience can trust.
Spinveri runs Instagram giveaway draws with a cryptographic commit-reveal scheme. Anyone can independently verify the winner was chosen fairly — no manual screenshots, no scraping, no doubt.

Run a fair draw
Configure your entry rules — tag a friend, include a hashtag, dedupe by user — and spin a wheel that picks one eligible commenter at random.
Public audit page
Every draw publishes a verification page. Your audience can independently confirm the winner was chosen fairly, with no behind-the-scenes nudging.
