Abstract

Non Fungible Token (NFT) Industry has been witnessing 16 million dollar trade in recent times.The following is the development of the decentralized NFT marketplace divided into three principal phases: smart contract development on the Ethereum blockchain using Solidity, creation of the frontend using React.js,Next.js,Node.js,HTML, CSS, and JavaScript, and backend development using Express.jsand MongoDB.The aim of this project is to offer a transparent and safe digital marketplace to mint, buy, and trade NFTs.The project employs ERC-721 standards for the uniqueness of tokens, Web3.js for interaction with smart contracts, and off-chain metadata storage with the help of REST APIs and MongoDB.Results indicate that the marketplace functions securely and efficiently, with seamless user interaction and successful on-chain transaction execution.Challenges related to deployment cost, metadata storage, and smart contract gas optimization were addressed during development.The final product demonstrates a fully functional, scalable, and decentralized NFT marketplace platform.
