NFT Marketplace

The NFT marketplace is the digital space where the NFTs are listed for sale in exchange for cryptos. The creators of the NFT list their NFT on these platforms either in the auction or open bid, where the users buy NFTs in which they are interested. In the past two years, several NFT marketplaces have evolved because young users have entered the crypto world, and most youngsters all over the globe have acquired knowledge of crypto and NFT. This results in developing and launching multiple NFT marketplaces for various concepts on different blockchain networks. Ethereum, Binance Smart Chain, Solana, Cardano, and Polygon are dominant blockchain networks where most NFT marketplaces are developed. Open Sea is the famous NFT marketplace with the most active users, and it is the only marketplace with the most number of the marketplace.

NFT Marketplace Development

The NFT marketplace is either developed from scratch or a white-label NFT Marketplace. An NFT marketplace from scratch will present your platform as unique to the users with all the unique features, including the marketplace functionalities. In the case of a white-label NFT marketplace, it is a 100% customizable platform with all its end-to-end functionalities of an NFT marketplace. Multiple features can be added to the NFT marketplace, even in the case of white labels, and most of them choose the white label NFT marketplace as it can be developed within less time and with minimum cost. The sample development codes are related to blockchain.

Create your own NFT Marketplace.

The NFT Marketplace is created with the below-mentioned workflow

Creating User Interface – Developers create the best user Interface for the marketplace, attracting the most users.
Coding Smart Contracts – The NFT marketplace is a decentralized platform where all the functions are performed with smart contracts.
IPFS, DB storage setup – All the NFTs of the marketplace are stored in the IPFS, where unique metadata and all other data are created for every NFT.
Integrating backend & frontend – After developing the NFT marketplace, the platform will be integrated with the user interface, making users easily access the platform.
Smart Contract Auditing – The platform is audited, and all the bugs will be fixed to perform their best without interruptions.
Deployment on Client’s Server – The completed marketplace is deployed on the client’s server and made available on the global market for the users.

In the case of the white-label NFT marketplace, the developers work on the available script used to develop the other NFT marketplace.

NFT Minting Process

Once the creator creates the digital asset, whether music, image, art, or anything else, it has to be minted as an NFT to list on the marketplace. The user mints the digital asset as an NFT and in any marketplaces with the pre-programmed smart contracts. The minted NFT will be stored in the blockchain network.

#Minting

A sample code on minting an NFT in the marketplace. A main function for minting digital assets as non-fungible tokens.

function Minting() {

let selectedOption;

const [ipfs, setIpfs] = useState([])

const [name, setName] = useState([])

const [description, setDescription] = useState([])

const [ipfsLink, setipfsLink] = useState([])

function mintToken() {

console.log(“Minting token…”);

console.log(“Form values: “, name, description, ipfsLink);

addNFT(name, description, getImage(ipfsLink), ipfsLink, getRandomInt(999999));

}

function handleChange(selectedOption) {

setIpfs(selectedOption.value);

console.log(`Option selected:`, selectedOption);

}

NFT Buy/Sell

The created NFT will be listed on the marketplace where the users can buy the NFTs in exchange for NFTs. The creator of the NFT can list the NFT with the royalty percentage, and the creator gets a fixed percentage for every NFT sale to the next person.

#Transaction

import { useContext } from “preact/hooks”;

import { TransactionContext } from “../components/TransactionContext”;

export const useTransactions = () => {

const { artifacts, setArtifacts } = useContext(TransactionContext);

return {

artifacts,

setArtifacts,

addArtifact: (a) => setArtifacts([…artifacts, a]),

removeArtifact: (a) => setArtifacts(artifacts.filter((b) => b.id !== a.id)),

isArtifactPending: (a) => artifacts.map((b) => b.id).includes(a.id),

};

NFT Exchange

The NFT is listed and bought by the user of the NFT marketplace. The minted NFT will be transferred from the seller’s wallet to the buyer’s. Most of the marketplace has third-party wallets like Metamask, Trust Wallet, and more where the NFT will be stored and transferred.

#Migration Contract

A sample code for migrating an NFT from the owner or the sender of the NFT to the receiver

pragma solidity >=0.4.25 <0.7.0;

contract Migrations {

address public owner;

uint public last_completed_migration;

modifier restricted() {

if (msg.sender == owner) _;

}

constructor() public {

owner = msg.sender;

}

function setCompleted(uint completed) public restricted {

last_completed_migration = completed;

}
