Provably Fair Decks

Unlike traditional sites where you have to trust the server, Jester Duel uses a client-seed hashing mechanism. This means neither the player nor the server can know or manipulate the deck sequence in advance.

  • The server generates a hashed secret seed.
  • You provide your own custom seed or browser entropy.
  • The shuffle is generated by combining both seeds.
  • Verify every single hand hash in the smart contract post-match.
