Provably-fair verifier

Paste the revealed server seed, the hash Hedge published before the bet, the client seed, and the nonce. We recompute the outcome with the same HMAC-SHA256 derivation the engine used at bet time, then compare it to the outcome you were shown. Everything runs in your browser - no request leaves this page.

The engine is open-source at packages/provably-fair. The reproducibility guarantee is byte-for-byte: any independent reimplementation will compute the same outcome from the same inputs.
