A very simple ERC20 token implementation using Hardhat

Simple ERC20 Token using Hardhat

This is a simple, barebones ERC20 token along with tests and a deployment script.

Compiling

npx hardhat compile

Running tests

npx hardhat test

Deploying your contract locally

NOTE: Before you can run the deploy script, you must first run a local hardhat blockchain network.

In a separate terminal window, run:

npx hardhat node

In another terminal window, run:

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

NOTE: You will need the contract address in the last step.

Interacting with your deployed contract

Lastly, to intercat with your contract in a local environment, run:

npx hardhat console --network localhost

And in the console, run:

// Instantiate token object and attach to contract address
const Token = await ethers.getContractFactory("PeterToken");
const token = Token.attach("<CONTRACT ADDRESS>");

// Get owner account address and other addresses
const [owner, addr1, addr2, ...addrs] = await ethers.getSigners();

Make a transaction:

// Get the owner balance and send your first transaction
const ownerBalance = await token.balanceOf(owner.address);

// Use .toString() method to avoid integer overflow errors
console.log(ownerBalance.toString());

// Send some PTK
const tx = await token.transfer(addr1.address, 5000);

// View transaction info
console.log(tx)

// Verify balance of addr1
const addr1Balance = await token.balanceOf(addr1.address);
addr1Balance.toString();
