Hardhat

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.
