This section showcases different design patterns for building contracts that integrate with the UMA Optimistic Oracle (OO). These include:
- An event based prediction market. In this example, settlement requests are submitted at the time of contract deployment, and the OO proposer network is used as a decentralized keeper service that identifies when settlement events happen and propose the outcomes.
- An Optimistic Arbitrator contract, where useful OO functions are wrapped together into single contract calls. Showcases how requests and proposals can be wrapped together into single calls to create "assertions", and requests, proposals and disputes can be wrapped together to create instant DVM arbitration situations.
