Stake Provably Fair Verifier
Free tool to verify any Stake Engine bet outcome from your account. Paste your bet's server seed, client seed, and nonce — the tool reproduces the exact outcome locally and matches Stake's official verifier. Supports every Stake Engine game on Stake.com and Stake.us.
How to verify a Stake bet
- Pick the game and mode from the dropdown.
- Paste your bet's client seed, server seed (the UNHASHED revealed value), and nonce.
- Hit Verify Bet — the tool reproduces the exact payout multiplier locally using HMAC-SHA256.
Why bets need a revealed server seed
While a Stake seed pair is still active, only the SHA-256 hash of the server seed is published — this is a commitment proving the seed wasn't changed after the fact, but it cannot reproduce bet outcomes. To verify a bet, rotate your seed pair under Account → Settings → Provably Fair, which reveals the previously-active server seed in your bet history.
