If you’re an avid user of the internet, you’ve probably come across the term NFT (Non-Fungible Token) in recently. NFTs are digital assets that are verified on the blockchain, which makes them unique and unable to be replicated or exchanged for something else. They have taken the art, gaming, and collectibles world by storm, and an NFT (non-fungible token) marketplace is a platform that allows users to buy, sell, and trade unique digital assets, known as non-fungible tokens.
But what exactly is an NFT marketplace, and how does it work? In this article, we’ll explore the world of NFTs and delve into the functions of an NFT marketplace, how they generate income, and how they are built.
What are NFTs?

As mentioned, NFTs are unique digital assets that are verified on the blockchain. They can be anything from artwork and collectibles to music and even tweets. The key thing to remember is that each NFT is one-of-a-kind and cannot be replicated or exchanged for something else.
The concept of NFTs has been around for a while, but it wasn’t until the explosion of blockchain technology that they really took off. The blockchain allows for the verification and authentication of these digital assets, making them valuable and sought after by collectors.
NFTs are bought and sold using cryptocurrency, most commonly Ethereum. The process of buying an NFT is similar to buying any other asset on the internet. You find the NFT you want to purchase, add it to your cart, and then complete the transaction using your preferred cryptocurrency.
One of the key features of an NFT marketplace is that the digital assets being traded are unique and cannot be replaced by another identical copy. This is in contrast to traditional digital assets, such as music or video files, which can be duplicated and shared without any loss of value.
Functions of an NFT Marketplace
An NFT marketplace is essentially an online platform where NFTs can be bought and sold. Think of it as an online art gallery or collectibles store, but for digital assets.
Some popular NFT marketplaces include OpenSea, Rarible, and SuperRare. These platforms allow users to browse through a vast selection of NFTs and make purchases using cryptocurrency.
One of the main functions of an NFT marketplace is to provide a secure platform for buying and selling NFTs. The blockchain technology used to verify NFTs ensures that the assets are authentic and cannot be replicated. This adds value to the NFTs and gives collectors peace of mind when making a purchase.
An NFT marketplace also serves as a platform for creators to showcase and sell their work. Many artists and collectibles creators use NFT marketplaces to reach a wider audience and monetize their creations.

Examples of NFT Marketplaces
There are a number of NFT marketplaces available today, each offering a different range of assets and services. Some examples include:
- OpenSea: One of the largest and most popular NFT marketplaces, OpenSea offers a wide range of digital assets, including art, collectibles, and even virtual real estate.
- Rarible: A marketplace for creators to sell their unique digital assets, including art, videos, music, and more.
- SuperRare: A platform for artists to sell their digital artwork as NFTs, with a focus on contemporary and digital art.
How NFT Marketplaces are Built
To build an NFT marketplace, the first step is to choose a blockchain to build on. Ethereum is the most popular choice for NFT marketplaces, as it has a robust infrastructure and allows for the creation of smart contracts.
Once the blockchain is chosen, the next step is to build the platform. This involves creating a user-friendly interface that allows for easy browsing and purchasing of NFTs. It also involves implementing secure payment options, such as the ability to purchase NFTs using cryptocurrency.
In addition to the front-end interface, the back-end of the platform must also be developed. This includes the creation of a database to store information about the NFTs and the users of the platform, as well as the implementation of security measures to protect against fraud and hacks.
To ensure the success of the NFT marketplace, it’s important to establish partnerships with key players in the NFT space, such as artists, collectors, and other marketplaces. This can help to bring more exposure to the platform and attract a larger user base.
An example of an NFT marketplace that has been built successfully is OpenSea. The platform was founded in 2017 and has since become one of the largest and most popular NFT marketplaces. It offers a wide selection of NFTs across various categories, such as art, collectibles, and gaming, and has partnerships with well-known companies and creators in the NFT space.
Different Networks Used in an NFT Marketplace
NFT marketplaces are built on top of various blockchain networks, each with its own unique features and advantages. Some of the most common networks used include:
- Ethereum: The most widely used network for NFTs, Ethereum offers a robust and secure platform for building decentralized applications.
- EOS: A faster and more scalable alternative to Ethereum, EOS is well-suited for high-volume transactions, such as those seen in NFT marketplaces.
- TRON: Another fast and scalable network, TRON is popular among creators and artists looking to sell their NFTs.
How NFT Marketplaces Generate Income
So, how do NFT marketplaces make money? There are a few ways that these platforms generate income.
One way is through transaction fees. When a user buys an NFT on an NFT marketplace, the platform takes a percentage of the sale as a transaction fee. This fee is typically a small percentage of the overall sale price, but it can add up when you consider the number of transactions that take place on these platforms.
Another way that NFT marketplaces generate income is through listing fees. Some platforms charge a fee to creators who want to list their NFTs for sale on the platform. This fee is usually a one-time charge and is used to cover the cost of verifying and authenticating the NFT.

This growth has been driven by a number of factors, including the increasing acceptance of blockchain technology, the proliferation of creative content on the internet, and the rise of digital collectibles and gaming.
