After deployment, the list of requisite addresses will be logged into your terminal. Add the addresses to the frontend/src/App.js file inside the correct load contract functions. They will look like this:
const loadPmknFarmContract = useCallback(async(_provider) => {
let pmknFarmAddress = "0x..."
let contract = new ethers.Contract(pmknFarmAddress, PmknFarm.abi,_provider)
setPmknFarmContract(contract)
}, [setPmknFarmContract])
Inside the Pmkn-farm/frontend directory:
npm i
before finally:
npm run start
