Four ways to play

From short-term price calls to playoff-style brackets, every format settles on-chain through an independent oracle.

Up/Down Markets

10 rounds, 5 minutes each. Beat the majority, split the pool.

Rolling Pot

Weekly parlay jackpot. Nail every pick to take the entire pot — each roll grows the prize and loosens the win threshold until someone lands it.

Playoffs

Seal a full bracket before tip-off. Highest score across every round wins the pool.

Parlays

Pick every game on the parlay. Whoever nails the most takes the pool.

Simple to enter Impossible to rig

1

Connect your wallet

Sign in with any Polygon wallet via Sign-In With Ethereum. No email, no KYC for read access.

2

Commit your prediction

Your entry is hashed locally and sealed on-chain. Nobody can see your pick until the reveal window opens.

3

Settlement and payout

The contract pulls a signed result from the oracle, verifies it, and pays winners automatically.

Open & auditable

Don’t trust us. Verify.

The rules are in the contract. We can’t change them, delay them, or override them.

Commit-reveal fairness

Your pick is hashed locally before it hits the chain. The contract sees a sealed commitment, not your choice, until the reveal window opens.

Oracle-verified settlement

Results come from Pyth price feeds or UMA Optimistic Oracle — signed off-chain and verified on-chain at settlement.

Skill-weighted rankings

Rankings weight win rate against rounds played. Consistency counts more than a single well-timed call.
