Casino verification

Verify

Check the seed commitment and reproduce the current game resolver’s deterministic outcome.

How it works

Server Seed Hash

Before you bet, we show you a hash of the server seed (commitment)

Combined Outcome

Server seed + your client seed + nonce determines the result

Verification

Rotate the seed, reproduce the outcome, and compare the recorded result

Your Fairness Seed

The server commits to this hash before each bet. Rotate to reveal the old seed.

This tool independently checks the commitment and HMAC in your browser, then calls the same current-version resolver used by settlement to reproduce the outcome. It is not an independent audit, does not prove that production ran this code for a historical round, and does not cover Poker, guest preview rounds, collusion, or account security. The HMAC binds the server seed, client seed, and nonce, not the stake or wager parameters; a loaded recent proof compares those separately with the stored round record.
