STEAMBATTLE

Provably Fair

Every case opening is verifiable. We use HMAC-SHA256 to generate results that neither the server nor the player can manipulate.

Algorithm

Server Seed

Generated before you play. You see its SHA-256 hash upfront. The actual seed is revealed when you rotate seeds.

Client Seed + Nonce

You set your own client seed. The nonce increments with each opening, ensuring unique results every time.

Verification

After rotating seeds, use the calculator below to verify that HMAC-SHA256(server_seed, client_seed:nonce) matches your roll.
