The requirement was to develop a fully functional NFT marketplace where users could easily mint, buy, and sell digital collectibles on the Ethereum blockchain. The client wanted a platform that offered both a user-friendly web interface and secure blockchain transactions. The system needed to allow creators to upload media files, set prices, and list NFTs for sale, while buyers could explore collections, filter by categories, view ownership details, and make purchases through their crypto wallets. The client also required integration with MetaMask for wallet authentication, Pinata IPFS for decentralized file storage, and the ability to deploy smart contracts using Hardhat to the Ethereum mainnet.
CLIENT’S REQUIREMENT
The requirement was to develop a fully functional NFT marketplace where users could easily mint, buy, and sell digital collectibles on the Ethereum blockchain. The client wanted a platform that offered both a user-friendly web interface and secure blockchain transactions. The system needed to allow creators to upload media files, set prices, and list NFTs for sale, while buyers could explore collections, filter by categories, view ownership details, and make purchases through their crypto wallets. The client also required integration with MetaMask for wallet authentication, Pinata IPFS for decentralized file storage, and the ability to deploy smart contracts using Hardhat to the Ethereum mainnet.
Solution
We built a decentralized NFT marketplace powered by Ethereum, using Hardhat as the blockchain development environment for deploying and testing smart contracts. The platform allows users to connect their MetaMask wallet directly from the browser to manage all blockchain interactions securely. Once connected, users can create and manage their profiles, showcasing NFTs they’ve created or purchased. For every new NFT, the user uploads media to IPFS via Pinata, enters details such as name, description, category, and price, and confirms the transaction in MetaMask. This confirmation triggers a blockchain transaction that mints the NFT and stores its metadata on IPFS, making it immutable and verifiable.
The marketplace displays the newest items, top sellers, and various collections, with filters for category, type, and price range to enhance browsing. Users can view NFT details, preview public profiles, and check which NFTs they own or have created. Once a buyer confirms a purchase through MetaMask, the NFT ownership is instantly transferred on the blockchain, and the user’s profile updates automatically to show the new asset under the “Owned” section. The entire process, from minting and listing to purchase and ownership transfer — happens seamlessly, providing a transparent and trustless digital asset experience.
