# Optimistic Oracle v3 This section showcases different design patterns for building contracts that integrate with the UMA Optimistic Oracle v3. These include: * A [quick start tutorial](quick-start.md) showcasing the simplest possible OOv3 integration contract. * Building example contracts: * [Prediction market](prediction-market.md) * [Insurance contract](in-depth-tutorial-insurance.md) * [A generic data assertion framework](data-asserter.md) * A description of [Escalation Managers](escalation-managers.md) and how they can be used. * Deploying [sandboxed oracle environment](../optimistic-oracle/sandboxed-oracle-environment.md) for testing the dispute flow.
