Dummy Token

A simple dummy token. Based on the HardHat Tutorial.

Setup

1. Run npm install to install dependencies
2. Run npx hardhat test to test the code
3. Start a local development ethereum node on a new terminal using npx hardhat node --hostname 0.0.0.0
4. Run npx hardhat --network localhost run scripts/deploy.js to deploy the Dummy Token contract, keep note of the Token Address that will output in the terminal.
5. Run npx hardhat --network localhost faucet <token-address> <your-address>, where <token-address> is the address of the Dummy Token contract deployed in the previous step, and <your-address> is your Ethereum address (i.e., your MetaMask account). This will fund your Ethereum account with ETH and mint DUMMY tokens.
6. Connect your MetaMask extension to the localhost network. You should have 1 ETH in your balance.
7. Add the Dummy Token to MetaMask:
   • Click on Add Token
   • Click on Custom Token
   • Paste on Token Contract Address the Dummy Token contract address (from step 4)
   • You should see 100 DUMMY tokens in your wallet

Adding a Development Network to MetaMask

   • New RPC URL: http://0.0.0.0:8545
   • Chain ID: 1337
   • Currency Symbol: ETH
4. Click "Save"

Hardhat Configuration

To ensure you always get the same account, define the account mnemonic in the hardhat.config.js file.

      accounts: {
        mnemonic: "test test test test test test test test test test test junk",
      },
      chainId: 1337,
