Run deterministic, auditable draws with cryptographic verification. Every winner selection is reproducible—so your audience never has to wonder if it was fair.
Four simple steps to run a giveaway that anyone can verify.
Link your Facebook or Instagram account securely to access your posts and comments.
Choose your giveaway post. We'll import all eligible comments automatically.
Winners are selected using a committed seed—results are mathematically predetermined.
Share a verification link. Anyone can independently confirm the draw was fair.
Before the draw, we publish a cryptographic commitment—a hash of the random seed we'll use. After the draw, we reveal the seed. Anyone can verify that the commitment matches and reproduce the exact same winner selection.
This means we can't change the outcome after seeing the entries, and you can prove to anyone that the selection wasn't manipulated.
Every draw generates a permanent record that withstands scrutiny from participants, legal teams, and platform policies.
