Solana · USDC · Provably fair

Three ways to get lucky

Scratchers, Raffle, and CryptoBall — one tap to play, one transaction, a result in under a second. The odds are locked on-chain before the first sale, and your own device checks them before it shows you a thing.

Provably fair

You don’t have to trust us. That’s the whole point.

Every game here runs on the same two-key structure. We commit to what is in the pool before anyone plays, and the chain decides who gets what. Neither half can move an outcome on its own — which is the only version of “fair” that survives us wanting to cheat.

  1. 01

    We commit

    Before a single sale, the entire prize pool is hashed into one merkle root and published on-chain, together with a hash of the seed it was built from. After that nothing can be added, removed, or swapped out.

  2. 02

    The chain deals

    Every play pulls a fresh Switchboard On-Demand random value to decide what you get. We know what is in the pool — we have published it — but we do not get to choose who it goes to.

  3. 03

    You check it

    Your card is verified against the on-chain root on your own device before the result is ever shown to you. When a drop closes we publish the seed, and anyone can rebuild the whole run and confirm the advertised odds were real.
