This project allows our frontend dapp to connect with UMA protocol. It comes with a contract, a test for that contract, and a script that deploys that contract. Next to that there is a second contract which extends the OptimisticOracleV3Interface from UMA.
Try running some of the following tasks to compile, test and deploy the contracts:
npx hardhat compile
pnx hardhat test
npx hardhat run scripts/deploy.ts --network polygonMumbaiPolygon Mumbai testnet: https://mumbai.polygonscan.com/address/0x7807A8d0fD161b0AB28a29b7A0Ca7d8059A1F95B#code
Polygon Mumbai contract is deployed with the gateway RPC

The V3 Oracle by UMA was not available on Polygon Mumbai testnet. By using this guide we deployed a sandboxed V3 Oracle on Mumbai to testing.
