* Building example contracts:
  * [Prediction market](https://docs.uma.xyz/developers/optimistic-oracle-v3/prediction-market)
  * [Insurance contract](https://docs.uma.xyz/developers/optimistic-oracle-v3/in-depth-tutorial-insurance)
  * [A generic data assertion framework](https://docs.uma.xyz/developers/optimistic-oracle-v3/data-asserter)
* A description of [Escalation Managers](https://docs.uma.xyz/developers/optimistic-oracle-v3/escalation-managers) and how they can be used.
* Deploying [sandboxed oracle environment](https://docs.uma.xyz/developers/optimistic-oracle-v3/sandboxed-oracle-environment) for testing the dispute flow.
