If this sounds thrilling, be a part of us as we cowl the ins and outs of making ERC721 tokens. If you happen to choose watching movies to be taught, you may as well take a look at the clip beneath from the Moralis YouTube channel. On this video, one in every of our gifted software program engineers walks you thru the steps introduced on this tutorial in additional element:
In case you are unfamiliar with the ERC721 commonplace or simply have to refresh your reminiscence, you’ll discover a piece answering the query, ”what’s an ERC721 token?” after the tutorial.
Now, with out additional ado, be a part of us as we kickstart this tutorial on create an ERC721 token by overlaying the required stipulations!
Stipulations
Earlier than transferring ahead to the central a part of this text – ERC721 token creation – you must have the next prepared:
Step 1: Set Up a Hardhat Venture
We are going to kickstart this tutorial on create an ERC721 token by displaying you arrange the basic mission. As such, open a brand new terminal and create a brand new listing utilizing the command beneath:
mkdir PROJECT_NAME
From there, ”cd” into the mission folder:
cd PROJECT_NAME
Subsequent, initialize a brand new “npm” mission:
npm init -y
With the ”npm“ mission initialized, set up the “dotenv” dependencies:
npm i dotenv
From there, set up Hardhat and the related dependencies:
npm set up –save-dev hardhat @nomicfoundation/hardhat-toolbox
Subsequent, create a brand new Hardhat mission utilizing the next terminal enter:
npx hardhat
Operating the command above prompts your terminal, and you may select to create a JavaScript mission:
If all the things labored, it is best to now see a hit message in your terminal:
Lastly, on this tutorial on creating ERC721 tokens, we’ll use OpenZeppelin. As such, set up the dependencies with this command:
npm set up @openzeppelin/contracts
Step 2: Construct the ERC721 Contract
After establishing the mission, open the listing in your most popular built-in growth atmosphere (IDE). We will likely be utilizing Visible Studio Code (VSC), and it is best to end up with a file construction just like the one beneath:
From there, open the ”contracts” folder and take away the instance contract:
Subsequent, create a brand new ”.sol” file within the ”contracts” folder, which is the place you’ll add the contract code itself. In our case, we’ll identify the file ”MNFT.sol”.
First, specify what model of Solidity you need to use. To take action, add the next code snippet on the high of the file:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
Subsequent, import the OpenZeppelin ERC721 token commonplace:
import “@openzeppelin/contracts/token/ERC721/ERC721.sol”;
Lastly, add the customized code for the contract itself:
contract MNFT is ERC721 {
constructor() ERC721(“Moralis NFT”, “MNFT”) {
// mint an NFT to your self
_mint(msg.sender, 1);
}
}
On the primary line, we offer a reputation and specify that the contract is an occasion of the ERC721 token commonplace. Subsequent, we outline a constructor, which is a operate that robotically executes when deploying the contract. Throughout the constructor, there may be one other constructor taking two parameters: the token identify and image.
Lastly, we add the ”_mint” operate, which takes two parameters. The primary ”msg.sender” parameter specifies that the one deploying the contract receives the token. The second parameter determines the variety of tokens that will likely be created.
All in all, your contract file ought to now look one thing like this:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
import “@openzeppelin/contracts/token/ERC721/ERC721.sol”;
contract MNFT is ERC721 {
constructor() ERC721(“Moralis NFT”, “MNFT”) {
// mint an NFT to your self
_mint(msg.sender, 1);
}
}
Lastly, open a brand new terminal, ”cd” into the mission folder, and compile the contract by working this command:
npx hardhat compile
Step 3: Create the ERC721 Token
Not solely will the final step of this tutorial illustrate create the ERC721 token, however it is going to additionally present you deploy it. To take action, open the ”deploy.js” file and exchange its contents with the next snippet:
const { ethers } = require(“hardhat”);
async operate essential() {
const nftContract = await ethers.getContractFactory(“MNFT”);
const deployedNFTContract = await nftContract.deploy();
await deployedNFTContract.deployed();
console.log(“NFT Contract Handle:”, deployedNFTContract.handle);
}
essential()
.then(() => course of.exit(0))
.catch((error) => {
console.error(error);
course of.exit(1);
});
On the preliminary line, we require ethers.js from Hardhat. Subsequent, we outline ”essential()”, the place we first name the ”getContractFactory()” operate utilizing the token image. From there, we name the ”deploy()” operate and look ahead to it to complete. Lastly, we log the contract handle.
Subsequent, it’s essential to create a brand new ”.env” file within the mission’s root folder. For this file, you must add two atmosphere variables:
QUICKNODE_HTTP_URL=”REPLACE_ME”
PRIVATE_KEY=”REPLACE_ME”
For the primary one, exchange ”REPLACE_ME” with a QuickNode URL, and for the second, add your MetaMask’s personal key.
As soon as achieved configuring the atmosphere variables, allow us to open the ”hardhat.config.js” file. From there, exchange the contents of this file with the code down beneath:
require(“@nomicfoundation/hardhat-toolbox”);
require(“dotenv”).config({ path: “.env” });
const QUICKNODE_HTTP_URL = course of.env.QUICKNODE_HTTP_URL;
const PRIVATE_KEY = course of.env.PRIVATE_KEY;
module.exports = {
solidity: “0.8.9”,
networks: {
goerli: {
url: QUICKNODE_HTTP_URL,
accounts: [PRIVATE_KEY],
},
},
};
Right here, we begin by importing the libraries put in through the second step and the atmosphere variables. What’s extra, by means of ”module.exports”, we deploy the contract.
Lastly, all that continues to be from right here is working the code to deploy the contract to the Goerli testnet by executing the command beneath within the terminal:
npx hardhat run scripts/deploy.js –network goerli
That’s it; congratulations! You’ve gotten now created your very personal ERC721 token in simply three simple steps! From right here, you possibly can observe the identical course of for creating extra ERC721 tokens sooner or later.
If you happen to skilled hassle throughout this walkthrough at any level, take a look at the video on the high of the tutorial. You can even discover the code for this mission within the GitHub repository beneath:

What’s an ERC721 Token?
Briefly, an ERC721 token is a token implementing the ERC721 commonplace. Accordingly, to adequately reply the query on this part’s title, we should begin by exploring the ERC721 commonplace. So, what’s the ERC721 commonplace?
ERC721 is an Ethereum commonplace for good contracts and non-fungible tokens (NFTs). The usual ensures that tokens originating from an ERC721 contract implement a minimal commonplace interface. Due to this fact, the ERC721 commonplace, as an example, ensures the next:
It’s attainable to question a token’s balanceA token is tradable between accountsAnyone can fetch the whole provide of a token
Together with these options, a contract must implement sure strategies and occasions to be thought-about an ERC721 contract. You’ll be able to learn extra about these occasions and strategies in our information explaining ERC721 good contacts additional.
Regardless that the ERC721 commonplace was initially created for the Ethereum ecosystem, it’s not solely restricted to this community. ERC721 is usually a typical NFT commonplace on all Ethereum Digital Machine-compatible (EVM) blockchain networks.
When Was ERC721 Created?
ERC is an abbreviation for ”Ethereum Request for Feedback”. Moreover, varied ERC proposals are used to recommend protocol updates or new requirements for the Ethereum community. The quantity ”721” merely signifies that this was remark quantity 721, which is a sign of when the usual was launched.
Nonetheless, to be extra particular, ERC721 was proposed by William Entriken, Jacob Evans, Dieter Shirley, and Nastassia Sachs in January 2018.
Different ERC Tokens
ERC721 just isn’t the one token commonplace on the market. Two different outstanding examples are ERC20 and ERC1155:
The ERC20 Customary – Not like ERC721, ERC20 is an ordinary for fungible tokens. An ideal instance of a token implementing the ERC20 commonplace is ETH, which is the native forex of Ethereum. You’ll be able to learn extra about the usual within the following article: “What are ERC20 Contracts?”. The ERC1155 Customary – ERC1155 targets fungible, semi-fungible, and non-fungible tokens, making it considerably extra dynamic. If you wish to learn extra about this commonplace, take a look at our information answering the query, ”what’s the ERC-1155 commonplace?”.
