Deploying to your Local Hardhat Blockchain

  1. Start a Hardhat Node

    npx hardhat node

  2. Open a new terminal and deploy smart contract in the localhost network

    npx hardhat run --network localhost scripts/deploy.js

  3. Step (2) will output your contract address to be placed in App.vue mounted when initiaing the contract.

    const contract = new ethers.Contract(
        '0x5FbDB2315678afecb367f032d93F642f64180aa3', // change this when deploy new contract
        ContractAbi.abi,
        signer
    )
