How to Build an NFT Marketplace like OpenSea
In this article, we will explain what is NFT, what is NFT marketplace, how to make an NFT marketplace without any coding, and how to make an NFT marketplace like OpenSea.
What is NFT?
Non-fungible tokens (NFTs) are the new craze in the blockchain community. NFTs are a type of token that are unique. That is, each NFT is different from all others in existence, even if they come from the same source.
These tokens can be used for anything from unique collectibles (like Cryptokitties), to digital representations of real-world assets (such as the recently announced partnership between MakerDAO and the Codex Consortium to tokenizing diamonds).
The NFT standard has been created by ERC-721, which is a standard for non-fungible tokens that allows for a token to represent one or more unique objects. These tokens can be bought, sold or traded with other NFTs.
What is the NFT Marketplace?
NFT marketplace is where digital collectables meet blockchain technology. It is a platform that lets you publish, buy and sell non-fungible tokens (NFTs) in a secure way.
In other words, NFT marketplace is a decentralized trading platform built on the blockchain that allows users to trade crypto assets for NFTs using a trustless, peer-to-peer system. The platform provides a high level of transparency, no counterparty risk, and low fees compared to other exchanges.
NFT marketplace works with the help of smart contracts, allowing users to trade their favorite blockchain-based assets securely. The ownership of NFTs is stored in their smart contracts, and users can prove that they own a token by unlocking it with the private key inside their wallet. Smart contracts provide transparency and security to the whole ecosystem.
Listed here are some of the best NFT marketplaces globally.

How to Create an NFT Marketplace like OpenSea?
OpenSea is a secure and trustless marketplace for NFTs. The OpenSea platform is built on the Ethereum blockchain and allows for peer-to-peer trading of non-fungible tokens. Launched in June 2018, OpenSea allows two types of users: sellers, who list their items, set a price, and determine what percentage of the sale goes to the network; and buyers, who can browse through different listings and purchase the item they are interested in.
OpenSea also offers a discovery feature which allows users to find items that are currently being sold on the platform. This discovery feature is extremely important because it adds liquidity to the marketplace by making sure that there is no overlap between listings. The discovery feature also helps maintain a healthy marketplace while keeping fees low.
Here is how to make an NFT marketplace like OpenSea.
Download Solidity Compiler
The first step is to download the Solidity compiler from the Ethereum website. Solidity is a programming language that is used to create smart contracts on the Ethereum blockchain. You will need to install this compiler on your machine and make sure it is running properly before proceeding to the next step.
Set up and Configure MetaMask
MetaMask is a browser extension that acts as a wallet for your browser. It allows you to manage all your tokens within the browser. The wallet can be used for trading on OpenSea or any other decentralized exchange (DEX). Before using the wallet, you need to install it on your browser and configure it to work with your account.
Install Truffle Framework
Truffle is an Ethereum development framework that helps you build, test, and deploy smart contracts. To build an NFT marketplace like OpenSea, you need to create a smart contract that will be responsible for managing all transactions on the platform. You need to install Truffle on your machine and use its testing framework if you are planning to create a smart contract in Solidity.
Create Your Own NFT Marketplace
Now that you have all the necessary tools, you can start building your own NFT Marketplace like OpenSea. You can either use one of the existing templates or create a new one from scratch. The templates are available online for free and come with all the necessary documentation for this purpose.
Create a User Interface
Once your smart contract is ready, you can create your user interface using any of the available templates online. These templates come with all the necessary code for creating a user interface for your NFT marketplace. However, if you are not comfortable using the templates, you can create your own from scratch and customize it to meet your business needs. If you are looking for an example, you can see the user interface of OpenSea.
Start Your Decentralized NFT Marketplace
Your smart contract is ready, and your user interface has been designed and developed. You can now deploy your smart contract on the Ethereum blockchain and start your marketplace. You can also connect your marketplace to MetaMask browser extension so that users can manage their tokens from their browsers.
Start Accepting Payments in Crypto or Fiat Currency
All transactions on OpenSea are conducted using Ether. If you want to replicate the same, you need to let your users pay via Ethereum or any other cryptocurrency. If you are replicating OpenSea, your users will mostly pay in ETH because it is the native currency of the Ethereum blockchain. However, there are some crypto-to-crypto exchanges where users can pay using Bitcoins or any other cryptocurrency. Accepting payments in fiat currency is also possible if you have a bank account.
Create a Reputation System for Users
OpenSea has a reputation system for its users. To build a similar reputation system on your own NFT Marketplace like OpenSea, you need to create an identity contract that will help you verify the identity of your users. You can also create a reputation system that will allow your users to rate other users on the platform after every transaction. The reputation system will be helpful in creating trust between buyers and sellers on your platform.
Develop Your Own Draggable Price Chart
You need to create a price chart for your marketplace. It will give you an idea of how much a particular token is selling for on your marketplace and what its future value might be. A price chart also gives you an idea of how much people are willing to pay for the tokens on your platform.
Develop a Decentralized Exchange for Your NFT Marketplace
If you want to replicate OpenSea completely, you will also need to build a DEX for your platform. DEXs are decentralized peer-to-peer exchanges where users can trade their tokens without having to depend on centralized exchanges or third parties. Creating a DEX for your platform is optional but recommended because it gives you complete control over the trading activities that take place on your platform.
Now that you know all about NFT, NFT Marketplace, how to make an NFT marketplace without any coding and how to make an NFT marketplace like OpenSea, don’t wait long. Use Appy Pie NFT marketplace builder to create your own NFT marketplace like OpenSea, and allow users to publish, buy, sell and trade NFTs without any hassle.
