Import the proper OpenZeppelin package. Moreover, in case you missed it earlier, we will perform all these steps in Remix. To be able to add the previously mentioned identifier, pragma line, and package import, create a new file within the contracts folder in Remix called “MoralisSmartToken.sol”:License Identifier – The license identifier will determine and signal the licensing status of our token. In this example, we’ll use the MIT license, which is open-source and free. To determine our license, we can input the following line of code into our project file:// SPDX-License-Identifier: MITPragma Line – Below the license identifier, we can add the pragma line. This will signal which version we’re going to use when compiling the token contract. This is very elementary, and in the example below, we signal that any Solidity version greater than 0.8.0 works:pragma solidity ^0.8.0;Importing the OpenZeppelin Package – Lastly, to finish the preparations before getting to the contract itself, we must also import the proper OpenZeppelin package: import “https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol”;Step 2 – Create the ERC-20 Token ContractAs we’ve added the license identifier and the pragma line and imported the OpenZeppelin package, we can move on to creating the ERC-20 token itself. As we mentioned previously, we will create an Ethereum contract, and for this example, we’ll call it “MoralisSmartToken“. Consequently, on our first line of code, our token looks something like this: contract MoralisSmartToken is ERC20 {In the example above, the name of the contract is set to “MoralisSmartToken”, which is something we can change.
