Settle Markets is a fully on-chain binary options exchange on Robinhood Chain. Every market is one question — "Will BTC be at or above $X at expiry?" — with YES and NO shares priced in cents, so a 62¢ YES is the market saying 62% likely. One winning share pays exactly 1 USDG. Orders match on an on-chain central limit order book; every order, fill, cancel and claim is a transaction you sign. Non-custodial: Settle never holds your funds.
