Verify · coin flip
Verify any Stake Coin Flip result.
Verify any Stake Coin Flip — heads or tails, reproduced from the seed pair.
Seed & hash checker
After you rotate seeds, confirm the revealed server seed matches the hash the house showed you up front.
How Coin Flip is derived
Flip is the simplest case: float < 0.5 is heads, otherwise tails. One float decides the outcome.
Every result here is computed with HMAC-SHA256(serverSeed, clientSeed:nonce:round) directly in your browser — nothing is sent to a server. Reproduce any other game on the full provably-fair verifier.
