Crypto markets on Polymarket typically settle against a specific index — the Coinbase spot price at a defined UTC moment is the most common. Binary markets pay $1 per YES share if the price closes above the threshold, $0 if not; scalar markets pay proportional to the final price. UMA's optimistic oracle handles any disputes. PolyGram adds a mobile-first interface, USDC deposits without a wallet, and portfolio analytics on top of the same underlying liquidity.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
