1. Set Up Your Development Environment
- Install MetaMask:
- Ensure you have MetaMask installed and configured to connect to the Nexi chain. Follow the instructions in the previous response if needed.
- Access Remix IDE:
2. Write Your ERC20 Token Contract
- 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
).
- 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
- 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).
- Compile the Contract:
- Click “Compile MyToken.sol” to compile the contract.
4. Deploy the Contract on the Nexi Chain
- 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.
- 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.
- 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
- Verify Token Deployment:
- Use a block explorer (if available) to verify that your contract has been deployed on the Nexi chain.
- Test Token Functions:
- Use Remix’s interface to interact with your contract’s functions (e.g.,
mint
, burn
, balanceOf
, etc.).
- Integrate with dApps:
- You can now integrate your token with decentralized applications or use it in your projects on the Nexi chain.
