NFT Marketplaces: Quick Summary

An NFT marketplace is a blockchain-based online platform to sell and buy non-fungible tokens (NFTs). The popularity of NFT marketplaces consistently grows fueled by skyrocketed prices for NFTs – the most expensive NFT as of the start of 2022 is “Merge” by Pak that has been sold for $91,8 million.

  • Steps to launch an NFT marketplace: Setting up a blockchain network, integrating chosen digital wallets, creating smart contracts, building a customer-facing web app.
  • Popular assets sold as NFTs: Images, music, videos, artwork, tickets, gaming staff.
  • Go-to blockchain platforms for an NFT marketplace: Ethereum, Binance Smart Chain, Polygon, Cardano.
  • Cost of NFT marketplace launch: $150,000 on average.
  • Timeframes for NFT marketplace launch: 4-6 months.

NFT Specifics and Viable Use Cases

An NFT represents a certificate of authenticity or ownership of digital assets, like images, music, videos, artwork, tickets. Though often compared to cryptocurrencies that also run on the blockchain technology, NFTs are unique and can’t be traded as equivalents  the way cryptocurrencies are traded.

NFTs are stored on a public blockchain and contain the information about:

  • Who and when created an asset.
  • Who and when bought the asset.
  • At what price the asset was bought.
  • Who owns the asset at the moment.

At ScienceSoft, we recommend our customers to leverage NFT value in the following markets:

Arts and collectibles

An NFT creator and then a buyer own a piece of art though can’t prevent the distribution of copies.

Key points to promote NFTs in art can be:

  • A sense of ownership is vital for true art collectors.
  • Digital artists can claim the ownership of their art and connect with buyers directly, eliminating third-party services (like Spotify).


The ticket information stored on the blockchain confirms the authenticity of a ticket and the identity of an owner.

Key points to promote NFTs in ticketing can be:

  • NFTs help combat speculative ticketing and ticket resales at inflated prices.

Gaming and metaverse

NFT marketplaces offer gamers in-game staff like weapons, characters, skins, etc.

Key points to promote NFTs in gaming can be:

  • NFTs are one-of-the-kind, thus give a competitive gaming advantage.
  • Gamers can independently trade NFTs they don’t use anymore.

Components and Architecture of an NFT Marketplace

Following ScienceSoft’s experience in end-to-end development of NFT marketplaces, we share an illustrated example of an Ethereum-based NFT marketplace with short explanations to key terms and tools used.

NFT marketplace architecture - ScienceSoft

Architectural components

  • A marketplace app is a web app where users sell and buy NFTs. Normally, it consists of client and server sides.
  • A digital wallet is an online service to store digital funds.
  • NFT metadata is the description of a digital asset sold as an NFT, specifically its name, creation date, attributes, owner, etc.
  • IPFS (Interplanetary File System) is a data storage system for distributed networks (blockchains). IPFSs are used to avoid power-consuming storing of digital assets with the metadata on the blockchain.
  • Smart contracts create a unique identifier for each NFT. Smart contracts for NFT marketplaces employ ERC-721 standard to create non-fungible tokens, which differentiates NFTs from fungible crypto tokens.
  • Blockchain is a distributed database that stores information about NFT transactions.

Techs and third-party services

  • Golang is the programming language ScienceSoft commonly uses for NFT marketplace back-end development.
  • Solidity is a programming language for smart contracts.
  • LevelDB is a database used for fast blockchain access.
  • AWS S3 is a cloud database that offers a range of storage classes for different data volumes.
  • is a service providing access to the Ethereum blockchain.
  • Ethereum is the blockchain most widely used for NFT marketplaces. It stores the NFT identifiers and links them to respective digital assets.
  • ETH Gas Station provides information about the cost of Ethereum transactions.
  • CoinMarketCap is a price-tracking service for the crypto market.

Key Steps of NFT Marketplace Development

If we summarize the experience ScienceSoft has had with blockchain-based marketplaces, we can describe the process of NFT marketplace launch in a number of key steps.

1. Defining a niche for an NFT marketplace. Among the most popular ones are artworks, video gaming content (e.g., online characters), music, sports memorabilia.

2. Choosing an optimal blockchain framework and launching the blockchain network.

NB! Though Ethereum is the most popular choice for NFT marketplaces, its transaction fees can be too high for a smaller company so don’t rule out alternatives.

3. Creating smart contracts that will be used to mint NFTs and trigger purchase transactions automatically if all the conditions of the sale are met.

4. Launching a web-based marketplace where users can act according to their chosen role: sellers upload their digital assets and buyers acquire associated tokens.

5. Setting up cryptocurrency payment gateways to enable marketplace users to buy, sell and transfer NFTs.

Why to Create a Multi-Chain NFT Marketplace

When launching an NFT marketplace, you don’t necessarily operate on a single blockchain. Actually, if you do, your marketplace will face the same limitations as the chosen blockchain network (for example, high transaction fees in case of Ethereum). Instead, we at ScienceSoft advocate for multi-chain NFT marketplaces integrated with several blockchain networks and also with various digital wallets. The resulting interoperability increases marketplace sustainability, optimizes blockchain energy consumption, and expands customer reach for your marketplace.

NFT marketplace integrations

Blockchain Platforms ScienceSoft Recommends


Open-source protocol

The most popular blockchain to develop an NFT marketplace. Ethereum is often accused of a large carbon footprint driving high transaction costs, however it is reported to be undergoing a series of upgrades and expected to reduce the footprint by ~99.95%.

Binance Smart Chain

Open-source protocol

This blockchain is compatible with Ethereum Virtual Machine, which means that no extra development work is needed for smart contracts to operate in both Ethereum and Binance Smart Chain. Relies on the Proof of Staked Authority (PoSA) mechanism that provides for lower transaction fees.


Open-source protocol

Uses a proof-of-stake protocol, the most energy-efficient protocol for blockchain networks, which explains low transaction fees. Though Cardano started to enable smart contracts only in 2021, there is already a number of NFT marketplaces based on the Cardano blockchain.

Tips to Succeed with an NFT Marketplace

Start with an MVP. Don’t invest your whole budget to get an end-to-end solution if you are excited to tap into a trending NFT market, still question the viability of your business idea. Prioritize key functionality with your development vendor to have a run-time version of your marketplace and launch it. Thus, you will get early feedback from users and move further much more confidently.

Employ a test-driven development approach to create smart contracts. When writing smart contracts, you need to identify all possible combinations of conditions that enable or fail a smart contract. Running test cases before writing code allows verifying requirements at early stages of development and save time on re-coding.

NFT Marketplace Development Cost and Timelines

According to ScienceSoft’s experience, an NFT marketplace development project lasts 4-6 months from the discovery stage through to the launch. Its average cost is about $150,000. The cost can vary depending on individual requirements of your project. As a rule, factors having the greatest impact on the cost are:

The sophistication of the marketplace design

The number of integrated blockchain networks

The number of integrated digital wallets

The number and complexity of smart contracts
