Configuring node

Now we need to configure these Contract Address inside /Constants directory

• Navigate to Constants/data.js

• Here we need to add the Oracle Contract Addresses for the respsective deployed Contracts

const APIOracleContractAddress = `0x25d5298617C53cA2E4f4BAB91Ee3D4FF37Ac05F6`;
const OptimisticOracleV2ContractAddress = `0x3CBb6Dbe62CB2D2Daa2019B44d5D19C46AB9Dc45`;
const OptimisticOracleV3ContractAddress = `0xa197690c527C4015e557185E42997d65348fD377`;
const PriceOracleContractAddress = `0x9eDf5612D5108dD5BcCb2da086a2C52ef58b03a0`;
const VRFOracleV2ContractAddress = `0x48749fde6370FBfc9a45C5EFB559253D72B7Cd53`;

• Next is to setup env variables in root directory

cp .env.example .env

• Set BRIDGE_PRIVATE_KEY as the private key of the Oracle Node interacting with the contracts , Ensure there is enough funds for gas.

• Set ORIGIN_RPC_URL as the URL from Alchemy for goerli Testnet , you can get one from here

• Set DEST_RPC_URL as the RPC URL of your new chain , where you want to add the Oracle

Now Configuration is done , Head over to run the Node
