Ethylene smart contracts

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 polygonMumbai

Sandboxed UMA V3 oracle:

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.
