Provably Fair
Every game result is cryptographically verifiable
How It Works
Server Seed
We generate a random server seed and show you its SHA-256 hash before you bet. The actual seed stays hidden until you rotate it.
Client Seed
You set your own client seed, which influences every game result. Change it anytime between bets.
HMAC-SHA256
Each bet result is derived from: HMAC_SHA256(serverSeed, clientSeed:nonce). The nonce increments with every bet.
Seed Rotation
When you rotate your server seed, the old one is revealed. You can then verify all past bets made with that seed pair.
Verify Your Bets
After rotating your server seed, you can independently verify any past bet by computing the HMAC-SHA256 hash yourself. The game result is deterministically derived from this hash.
