Provably Fair Verifier

Independently verify any Stake.com bet using HMAC-SHA256 โ€” runs entirely in your browser, nothing is uploaded.

How it works: Stake commits to a server seed (by showing you its SHA-256 hash) before each bet. After rotating seeds the server seed is revealed โ€” paste it here along with your client seed and nonce to recompute the exact outcome via HMAC-SHA256(server_seed, client_seed:nonce).
