How to implement a no-code deployment of an ERC20 token using Remix and OpenZeppelin

Preparation

Before you start with the actual deployment of the ERC20 token, there are a few preparatory steps you need to follow:

1. Install MetaMask here (opens in a new tab).

2. Get Some Test FLA here (opens in a new tab).

3. Add FLA Testnet here.

4. Open remix (opens in a new tab)

Step 1: Create a new file

Create a file named erc20.sol in the contracts directory.

Step 2: Paste the Code and Modify Parameters

Copy and paste the following Solidity code into the erc20.sol file. This code imports the OpenZeppelin ERC20 contract and sets up a basic ERC20 token:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
 
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
 
contract MyToken is ERC20 {
    constructor() ERC20("MyTokenName", "MTK") {
        _mint(msg.sender, 10000 * (10 ** uint256(decimals())));
    }
}

Change the parameters in the constructor to customize the token:

• name: The name of your token. MyTokenName

• symbol: The symbol of your token. MTK

• initialSupply: The initial supply of your token 10000(in whole units, it will be multiplied by 10^decimals() within the contract).

In this example, the token name is "MyTokenName", the symbol is "MTK", and the initial supply is 10,000 tokens.

For example

Deploy a token with:

• name: LaughCoin

• symbol: LOL

• initialSupply: 100000000

Step 3: Compile the Contract

1. Click on the "Solidity Compiler" tab on the left sidebar.

2. Select the appropriate compiler version (0.8.x).

3. Click on "Advanced Configurations" to expand the advanced settings.

4. Choose EVM Version "paris".

5. Click "Compile erc20.sol".

Step 4: Deploy the Contract

1. Click on the "Deploy & Run Transactions" tab on the left sidebar.

2. Set the environment to "Injected Web3" if you are using MetaMask, or "JavaScript VM" for a simulated environment.

3. Click "Deploy".

Step 5: Expand the Deployed Contract

1. In the "Deployed Contracts" section, find the contract you just deployed.

2. Click on the contract name to expand it. This will show you a list of available functions and variables that you can interact with.
