The popularity of digital marketplaces for various types of products is increasing daily. NFTs are becoming popular outside of the crypto sphere, meaning NFT marketplaces are evolving as well.

Marketplaces are where the general public can interact with content creators and are the entities responsible for facilitating NFT trading. Now, every content creator can become a prominent market seller just by participating in NFT marketplaces. As a new industry, there’s plenty of space for new ideas and niches. Thinking about creating your own NFT marketplace? In this article, we’ll discuss the various steps and costs involved.

What is an NFT marketplace?

Non-fungible token (NFT) marketplaces are Web3 applications that allow people to buy and sell various types of NFTs. Some marketplaces are open to the public, such as those that allow people with crypto wallets to buy and sell their own NFTs. Others are not open to the public and only allow certain companies and brands to sell their NFTs.

With an NFT marketplace, people can easily create accounts and sell their digital artworks and other items. Niche marketplaces are usually more in demand than standard ones due to their specialized features and ability to sell various types of art.

How does an NFT marketplace work?

The users of an NFT marketplace must first install a digital wallet to operate. This app stores the data of the owner's files on the blockchain, which is different from the data stored on a disk drive. In addition, it allows users to create collections by displaying the work or digital item they want to buy. They can then choose the payment token they want to accept.

After the item has been listed, the transaction will be created following the auction. The creator's wallet then launches a smart contract to spell out the terms of the deal between the buyer and the seller. The blockchain network automatically generates and validates this deal.

The transaction is then irreversible, as various operational costs are involved in a digital transaction. For instance, the energy costs associated with brokering a transaction, the gas fee, are usually included in the cost of an NFT. As a result, marketplaces use NFTs to charge a fee whenever funds are transferred.


Things to know before building an NFT marketplace

Non-fungible token standards

The standards used to create NFTs ensure a token behaves properly and efficiently. Currently, two standards are used to create an NFT: the Ethereum Improvement Proposal ERC-721 and the Ethereum Improvement Proposal ERC-1155.

The "transferFrom" feature, which allows a blockchain to transfer assets from one owner to another, also improves an NFT's efficiency.

Non-fungible token metadata

The concept of the NFT space is also known as "OwnerOf." This allows users to easily find the owner of a token.

Legal documentation

The legal documentation of an NFT also includes details about a company's formation, IP consideration, privacy policy, and terms of service.

Creating an NFT marketplace

There are several phases to consider when creating a marketplace.

How to create a NFT marketplace.

Phase 1. Discovery

The discovery phase is the most crucial step in the development of your NFT marketplace. It involves gathering information about your project's technical feasibility and determining its technical viability.

Some questions that are worth answering in this phase:

  1. What the type of NFT do you want to work?
  2. How well do you know about it?
  3. Do you know your audience?
  4. Who are your competitors?
  5. How to monetize your platform?
  6. What token protocol is more preferable for you and why?
  7. What technology stack do you need?

Before you start working on a project, first gather information about the platform’s structure, roles, and front-end and back-end operations. Involving software architects will give you a good idea of the technology's capabilities and implementation, and finding a good business analyst with the necessary skills to create comprehensive architecture documentation will also help you better understand hosting requirements.

Phase 2. Development

After gathering information about the site's features and user flows, designers and business analysts start working on the wireframe and layouts. The goal is to create a well-designed and accurate representation of the website's user interface.

The development phase can be divided into 3 branches of work:

  • UX/UI designers create a well-designed and user-friendly interface that demonstrates a strong understanding of the various requirements of your target audience and market trends.
  • Back-end developers build the internal structure of the website. Since an NFT platform is a decentralized one, most of the data is stored on a blockchain, which is different from the traditional development process. Creating smart contracts and back-end systems is a huge part of the work that goes into building a successful platform. This includes working on various aspects of the ecosystem, such as the marketplace, blockchain, and wallets.
  • The front-end developers create the interface that handles the interactions between users and the platform. This is the main task during the development phase, and its main objective is to ensure that the platform is reliable and easy to manage.

Phase 3. Testing

During this phase, the QA team performs various tests to verify that the code is bug-free and works exactly as intended. They will also check the content of the pages and perform other tests to guarantee that the platform is safe and secure. Another essential test confirms the operation of the NFT marketplace on the staging server.

Phase 4. Deployment & support

The team successfully deploys the NFT marketplace on the production server and starts working on the support services to help users navigate the platform's various features. This step also includes planning the platform's future development to meet users' needs.

The cost of developing an NFT marketplace depends on the number of features that you decide to include. Read on to learn about the essential features of a successful NFT marketplace.

The must-have features for NFT marketplace:

Feauters of NFT

The Storefront section of the NFT marketplace provides users with a variety of information about a listing, such as its details, owner, and bid history. Since NFT platforms are similar to e-commerce sites in terms of their structure, they require an easy-to-use storefront that holds all the necessary data. Site administrators should be able to set the number of details that will be displayed for each file. It’s also important to know the provenance of the files, as well as their rarity.

Although an NFT cannot be copied, it can be released multiple times, and a marketplace will label these editions as "Number 8 of 10," which is important to collectors.

The platform also needs to support category management and search functionality to make it easier for users to search for various types of products. This will allow them to easily add their details. It can also be used to filter listings by price, rarity, and artist.

Another necessary feature in an NFT marketplace is the ability to create listings. Sellers should find it easy to search for and buy various types of art and collectibles, effortlessly list items, and quickly enter all the necessary details.

Also include the ability to manage the buying system and auctions when building your NFT marketplace. This will allow the users to easily add bids, expiration dates, and a watchlist displaying the details of the bid.

Remember to include a wallet. Aside from sending and receiving cryptocurrencies, a wallet will also allow users to store and manage their NFTs and other digital assets. Your team can either create an in-app wallet or integrate existing ones into the application.

Include the ability to send out notifications as well. A notification system will allow both buyers and sellers to receive notifications when an offer has been made, either through e-mails or push notifications. It can also be used to notify the public about the launch of new non-fungible tokens and the upcoming auctions.

A rating system is a useful tool for both buyers and sellers in the NFT business model. It helps deter negative behaviors such as backtracking and false representation. Having a scoring system prevents transactions from going through before a smart contract is implemented.

While the main features of an NFT marketplace are usually related to creating NFTs and multi-payment gateway integration, other features, such as the ability to merge multiple platforms, are also available. These allow entrepreneurs to create their own unique trading platforms.


How much does it cost to create an NFT marketplace?

Prices range anywhere from $30,000 to $500,000 due to the wide variety of factors involved in the development process. Consider them when planning your NFT marketplace:

  • Number of features included
  • Level of customization
  • Developers salary
  • Tech stack
  • Time limits for development
  • Third-party API integration

The table below provides an approximate breakdown of the costs per feature that is relative to the geography of the developers you’ve hired. Note that this only refers to the cost of developing a marketplace.

Keep in mind that the duration and cost of building an NFT marketplace depend on the complexity of the features that you choose for your application and geographic factors.

Moreover, this table does not consider the costs of:

  • Infrastructure, including the server itself
  • QA and trial to make sure everything works correctly
  • Normal and validated staging to keep the customer satisfied with the result of the software. Some features may need to be changed at this stage, followed by a re-discovery phase.
  • Communication and documentation

These points can add from 30 to 50% to the specified cost in the table.
