Pay a small entry, predict crypto prices, sports brackets or pick-em pools, and the players who outperform the field share the prize pool. Every round is resolved on-chain by an oracle — not by us, not by a house.
Why Arena
Your prediction is sealed with a cryptographic hash before the round closes. Nobody — including us — can see your pick or copy your move until the reveal window opens.
Asset markets settle with Wormhole-signed Pyth price updates verified on-chain. Sports tournaments resolve through UMA's Optimistic Oracle. The operator carries signed bytes — never fabricates outcomes.
Rankings combine win rate with sample size, so a single lucky round doesn't crown anyone. Consistency beats variance, and the math is the same for everyone.
How it works
Connect your wallet
Sign in with any Polygon wallet via Sign-In With Ethereum. No email, no KYC for read access.
Commit your prediction
Pick a side, fill out a bracket, or commit a full pick-em sheet. Your entry is hashed locally and sealed on-chain — invisible to other players until the reveal window opens.
Settlement and payout
When the round or game closes, the contract pulls a signed result from the oracle, verifies it, and pays winners automatically. Nothing manual, nothing trusted.
Verifiable by design
Asset markets settle with Pyth Network price updates signed by the Wormhole guardian set, with strict publish-time windows and per-market confidence caps that reject stale or wide-spread prints. Sports tournaments resolve through UMA's Optimistic Oracle. In both cases the operator key is a liveness role only — it relays signed bytes from the oracle, nothing more.
Markets are open. Pick a side, commit your prediction, and let the chain decide.
