How to Create an NFT Marketplace in 2022

NFT Marketplace

With NFT (non-fungible token) marketplaces, producers get to display their NFT’s art to the masses. Moreover, by listing NFTs to a marketplace, tokens acquire a lot of publicity since markets for NFTs attract large amounts of traffic due to NFTs’ surge in popularity. As such, NFTs creators don’t need to worry too much about auctioning and getting their NFTs tokens sold. However, there are not just crypto enthusiasts that are interested in NFTs, but also huge corporations. As such, now is a perfect moment to start learning NFTs token development. Specifically, understanding how to develop an NFT marketplace is a highly sought-after talent that every programmer should know how to perform. Therefore, we’ll cover in this post the development method of how to establish an NFT marketplace with Market and its ultimate Web3 development platform.

Since we are still early in the game regarding NFTs and their use cases, who knows, any developer aiming to become a blockchain developer might be the one establishing the next great NFT marketplace that the public will adopt. Of course, there will always be big NFT marketplaces, but it makes sense for every NFT launch or collection to have its own NFT marketplace. Moreover, you might receive the next opportunity to establish a marketplace devoted to NFTs for a significant blockchain company. As such, being able to construct an NFT marketplace is a skill that might future-proof your job, and with the help of Markets, it is a skill you can readily master.


What is an NFT Marketplace in 2022?

Before we embark on an example project that will teach you how to establish an NFT marketplace with minimal work and in record time, we need to make sure you know all the essentials. An NFT marketplace is essentially any Web3 application that concentrates around selling and buying any form of the non-fungible token (NFT) (NFT). As such, there can be different sorts of NFT marketplaces such as one accessible to the general public, where anyone with a crypto wallet can buy and advertise their own NFTs. On the other hand, there are also NFT marketplaces that aren’t open to the public. Specifically, these only let a certain firm or brand sell their NFTs, and do not allow users to list their NFTs.

In addition, utilizing NFTs metadata, you can set multiple sorts of functions in place to provide specialized functionality.

In case you are not yet familiar with NFTs, we recommend checking out some of our earlier articles addressing themes such as “what are NFTs?”, “how to mint NFTs”, and taking a closer look at the two most prominent NFT token standards – ERC-721 token standard and ERC-1155 token standard.

Why You Need to Learn to Create an NFT Marketplace

There are infinite potential surrounding NFTs and their use cases, such as NFT games, collections, NFT artwork, etc. However, while utilizing existing NFT marketplaces may seem like a good idea, most of them come with certain sorts of constraints. In most situations, they are not genuinely decentralized, and their cross-chain compatibility tends to be exceedingly poor. Furthermore, the bulk of NFT marketplaces still limit users to the Ethereum blockchain, and they tend to impose their own fees. These are only some of the biggest drawbacks to various marketplaces. But, is there a strategy to overcome these downsides? Yes – construct your own NFT marketplace.

However, don’t be disappointed if you have no audience, and you’ll end up paying a lot in marketing to make it the next major marketplace; since we are so early in the industry, everything is possible!
You can easily offer to develop an NFT marketplace for many other firms, artists, and celebrities wishing to launch their NFTs. Of course, you can already help them develop NFTs; nonetheless, it makes sense, not only for them but for everybody seeking to sell their NFTs to have their own NFT marketplace. Why? Well, you are in control of the marketplace and you design the UI (user interface) to particular criteria. Moreover, you’re not susceptible to platform manipulation, and you get to cut out possible intermediaries charging you fees on top of the already pricey gas expenses, etc.

In addition, you can determine and implement specific features of the dApp. In that manner, you can provide functions that other platforms don’t offer. As such, offering customers an NFT marketplace and ensuring they get to answer all their demands without leaving that particular platform makes a lot of sense. Therefore, knowing how to establish an NFT marketplace gives the nearly unlimited potential for developers.

How to Create an NFT Marketplace in 2022

Here at Market, we believe in learning by taking quick action. Therefore, we’ll take on a basic example project herein that you can follow along with. As such, we shall construct an NFT marketplace in the following parts. Of course, we will be leveraging Markets’ SDK, including its ultimate NFT API, to do our assignment with utmost ease.

A Preview of Your NFT Marketplace in 2022

Before we start with the coding component, we want you to have a clear image of what we will construct. Looking at the figure below, you can see that our example NFT marketplace will provide consumers many options and services, including:

Display the user’s native token balance at the top.
An “On Sale” area, highlights the current available NFTs in our marketplace.
The “Purchase/Sell” section reveals NFTs that the user selects to take action on (buy or sell) (buy or sell).
The “Your NFTs” section will display collections that the logged-in user holds.
There are presently no NFTs under the “On Sale” and “Buy/Sell” section because there is no NFT that we or any other user on our example NFT marketplace is selling.

Our Example NFT Marketplace

If we select one of our NFTs, it will then be offered in the “Buy/Sell” area. Next, we have an option to input the price and offer the NFT in question for sale by selecting the “Offer for Sale” button. Then, we need to approve the transaction by clicking the “Confirm” button in the MetaMask pop-up box. This window will prompt automatically.
Once we confirm the transaction and its processes, we will be able to view the NFT in the “On Sale” area.
Our Example NFT Marketplace – Buying an NFT
Of course, we cannot buy our own NFT; however, if another account is logged in, it can purchase that NFT. As such, in the graphic below, you can see how another account will purchase the NFT we’ve specified above. So, it first clicks on the “Select” button next to the NFT in the “On Sale” area. It then clicks on the “Buy” button for the NFT that’s now available in the “Buy/Sell” section. By hitting this button, MetaMask will initiate to confirm the transaction.
After you purchase the NFT, it is no longer in the “On Sale” column. Instead, it shows in the “Your NFTs” area for the account (bearing in mind that it may take a bit for the transaction to complete):
Once the transaction is complete, the new owner can sell that NFT.

How to Create an NFT Marketplace with Techsnopes

Now that we know what we will construct, it is time to list the backend features and components required to make the functions exhibited in line with what we’ve discussed in the previous part. These are as follows:

User authentication lets our users to login into our app.
We need to be able to track the balances of our users in real-time.
We need to be able to track smart contract occurrences in our dApp. We rely on smart contracts that are operators of our marketplace and other smart contracts, including those used to mint NFTs.
Implementing all of the above backend features would be quite tough if we were to take on this quest by developing directly on top of an RPC node. However, when we utilize Market, we get to cover the entire backend of our App by simply copying and pasting short pieces of code from Market’s manual. As such, the Market makes it uncomplicated to construct an NFT marketplace. Moreover, you save a lot of time, which means you get to focus exclusively on the front end and give the finest user experience.

The Ultimate Shortcut to Create an NFT Marketplace with TechSnopes

When you create your free Market account, you get to create a Market server, which is the beginning point in order for you to build Apps with a trading Market. Once you have an active server, you get to employ the Ethereum API among all of its other tools.

Moreover, Markets servers give many extra capabilities, such as establishing sync events. For the servers utilized for our example, we will establish two listeners to detect specific smart contract events. One listener for detecting when a new offer is placed (selling) and another one to detect when an offer is closed (buying):
Furthermore, Market also gives you a complete database containing live details regarding your consumers, which is available within your Market dashboard. These include token balances, transaction histories, pending transactions, NFTs, and much more. This is also where the data regarding our listeners (underlined with green lines) is available:
Now that we’ve got the on-chain data at our disposal, we merely need code snippets to utilize that data correctly.

How to Create an NFT Marketplace

There are two key aspects to the coding necessary to construct an NFT marketplace. For one, we need to construct a dApp that will function as an approved contract operator of the marketplace. At the same time, we need to employ a smart contract that will ensure all transactions happen properly. Let’s first look at the latter.
The gist of the smart contract utilized for our example may be seen by looking at the events it covers:
The rest of the smart contract code explicitly identifies particular routines that ensure the above four occurrences are adequately covered. In that manner, users can only sell NFTs in their possession, while purchasers can only purchase listed NFTs. Moreover, the method ensures that the price gets associated with the token in question.

How to Create an NFT’s Marketplace in 2022

This is the part that probably intrigues you the most. Here’s where we ensure that the users get to see and use our NFT marketplace. For the purpose of our sample project, we produced three files: “logic.js”, “cloudCode.js”, and “index.html”. The whole code for each file is also available on GitHub. We ensure the primary operation of our program with the “logic.js” code. As such, it deserves some particular attention. This is also when the full power of markets gets to be put to action. Moreover, to initialize Market, you need to paste your Markets server URL and application ID:
