Provably fair

Every Aviator round is decided before the plane takes off — and you can prove it.

1. When betting opens, we publish the SHA-256 hash of the round's secret seed. The crash point is already locked in at this moment.
2. After the round crashes, the seed is revealed. Hash it yourself and confirm it matches the hash we committed to.
3. The crash point is derived from HMAC-SHA256(seed, roundId): take the first 52 bits as a number h. If h mod 33 = 0 the round busts instantly at 1.00× (this is the ~3% house edge); otherwise the crash point is floor((100·2⁵² − h) / (2⁵² − h)) / 100.

Because the hash is published before bets close, we cannot change the outcome after seeing your bets — and because the seed is revealed after, you can verify every single round independently.
