Fully On-Chain Orderbook

No off-chain sequencer. No centralized matching engine. Every order, every fill, every fee distribution happens transparently on Base. Three settlement paths keep liquidity flowing even in thin markets.

Day-One Liquidity

No Sellers? No Problem.

Three settlement paths mean your venue generates liquidity even when orderbooks are thin. Mint-to-Fill lets two opposing buyers create tokens from nothing. No market makers required to get started.

Trustless Resolution

No Ref Needed. UMA Calls It.

Markets resolve through UMA's Optimistic Oracle — no centralized authority decides outcomes. Assert, challenge, settle. Configure liveness windows and bond amounts per venue.

Use Cases

One Protocol. Any Outcome.

Wherever there's an outcome to predict, there's a venue to build.

Sports & Tournaments

Winner Takes All. The Rest Auto-Resolve.

Create multi-outcome markets where all choices are mutually exclusive. When one outcome resolves YES, every other option settles to NO automatically.
