Hardhat: Deploy ERC20 Contract

Step 1. Enter smart-contract-example/hardhat folder

$ cd smart-contract-example/hardhat

Step 2. Run npm install inside the folder

$ npm install

Step 3. Make a copy of .env.example to .env

$ cp .env.example .env

Step 4. Modify .env and fill ONE of the field

MNEMONIC=goose easy ivory ...

PRIVATE_KEY=XXXXXXX

Step 5. Review Migration Script at scripts/deploy-pool-token.js

async function main() {

const PoolToken = await hre.ethers.getContractFactory("PoolToken");

const poolToken = await PoolToken.deploy("Pool Token", "CRT", "1000000000000000000000000");

await poolToken.deployed();

console.log("PoolToken deployed to:", poolToken.address);

}

Step 6. Endpoints setting

By default, the script will be using your local host "127.0.0.1" - If you are not running a localhost, you may leverage the public endpoint http://13.213.36.146:6868/ by making changes to networks in hardhat.config.js, for example:

networks: {

development: {

url: "http://localhost:8545",

accounts: getHDWallet(),

},

testnet: {

url: "http://13.213.36.146:6868",

accounts: getHDWallet(),

},

},

Step 7. Deploy Contract

npx hardhat run --network <your-network> scripts/deploy-pool-token.js

Step 8. Obtain Contract address from the console and input to Metamask

The correct balance will be shown on the Metamask page.
