Write Your First Token

This guide will walk you through the process of creating and deploying your first token on the Pharos blockchain. By the end of this guide, you will have a fully functional token contract and understand how to interact with it.

Prerequisites

Before you begin, ensure you have the following:

Git: Used for code management and obtain examples.
Node.js: Install it from .
Pharos Devnet/Testnet Access: Access to a Pharos node (local or remote) for interacting with the blockchain.

Setup 1: Install Hardhat

Setup 2: Set Up the Project

Clone the example repo:

git clone https://github.com/PharosNetwork/examples
cd examples/token/hardhat/contract

Install OpenZeppelin Contracts:

npm install

Setup 3: Write the Token Contract

Create a New Solidity File:

Create a new file for your token contract:

touch contracts/Token.sol

Write the Token Contract:

Open contracts/Token.sol in your favorite text editor and add the following code:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract Token is ERC20 {
    constructor(uint256 initialSupply) ERC20("Token", "MTK") {
        _mint(msg.sender, initialSupply);
    }
}

Compile the Smart Contract:

npx hardhat compile

Test the Smart Contract

npx hardhat test

Step 4: Deploy the Token Contract

Set the private key:

npx hardhat vars set PRIVATE_KEY

Deploy the Contract:

npx hardhat ignition deploy ./ignition/modules/Token.js --network pharos

Troubleshooting

Contract Deployment Fails: Ensure you have enough testnet tokens to cover the deployment cost.
Interaction Issues: Verify that the contract address and ABI are correct.
Insufficient Balance: Ensure your wallet has enough tokens to transfer.

Conclusion

Now that you’ve created and deployed your first token using Hardhat.

This guide provides a comprehensive introduction to creating and deploying a token on the Pharos blockchain using Hardhat. If you encounter any issues, refer to the Troubleshooting section or consult the Hardhat documentation. Happy building! 🚀
