1. Set Up Your Development Environment

1. Install MetaMask:
   • Ensure you have MetaMask installed and configured to connect to the Nexi chain. Follow the instructions in the previous response if needed.
2. Access Remix IDE:
   • Open Remix IDE in your browser.
     

2. Write Your ERC20 Token Contract

1. Create a New Solidity File:
   • In Remix, go to the File Explorer panel.
   • Click on the New File icon and name your file (e.g., MyToken.sol).
2. Write the ERC20 Token Contract:
   • Copy and paste the following Solidity code into your new file. This code creates a simple ERC20 token contract:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

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

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

    // Function to mint new tokens, only accessible by the owner
    function mint(address to, uint256 amount) external onlyOwner {
        _mint(to, amount);
    }

    // Function to burn tokens from the owner's balance
    function burn(uint256 amount) external onlyOwner {
        _burn(msg.sender, amount);
    }
}

• This contract uses the OpenZeppelin library for the ERC20 standard and ownership control.
  

3. Compile the Contract

1. Select Compiler Version:
   • Go to the Solidity Compiler tab in Remix (left sidebar).
   • Choose the Solidity version that matches your contract (e.g., 0.8.0).
2. Compile the Contract:
   • Click “Compile MyToken.sol” to compile the contract.
     

4. Deploy the Contract on the Nexi Chain

1. Configure Remix to Use MetaMask:
   • Go to the Deploy & Run Transactions tab in Remix.
   • Set the Environment to “Injected Web3”. MetaMask should automatically connect to the Nexi chain.
2. Deploy the Contract:
   • Select your contract (MyToken) from the dropdown menu.
   • Enter the initial supply for your token in the “initialSupply” field (e.g., 1000000).
   • Click “Deploy” and confirm the transaction in MetaMask.
3. Confirm Deployment:
   • Once deployed, the contract address will appear under “Deployed Contracts” in Remix. You can interact with the contract from this section.
     

5. Interact with Your Token

1. Verify Token Deployment:
   • Use a block explorer (if available) to verify that your contract has been deployed on the Nexi chain.
2. Test Token Functions:
   • Use Remix’s interface to interact with your contract’s functions (e.g., mint, burn, balanceOf, etc.).
3. Integrate with dApps:
   • You can now integrate your token with decentralized applications or use it in your projects on the Nexi chain.
