NFT Marketplace

The following is a UML sequence diagram of the project

Overview

NFT Marketplace is a full-stack decentralized application (dApp) designed to create a cost-efficient and secure marketplace for Non-Fungible Tokens (NFTs). This project integrates both centralized and decentralized backends to optimize cost without compromising security. The smart contracts used in this project are developed with a focus on cost efficiency while ensuring the security of the marketplace. Additionally, this project serves as an educational resource for anyone interested in learning about building dApps and NFT marketplaces.

Features

• Decentralized and Centralized Backend: Combines the strengths of both decentralized and centralized systems to balance cost and performance.
• Cost-Efficient Smart Contracts: Designed to minimize gas fees and other costs associated with blockchain transactions.
• Secure Transactions: Emphasis on maintaining the security and integrity of the NFT store.
• Technology Stack: Utilizes Next.js and JavaScript for the frontend, PHP for the backend, and various databases, including MySQL, to manage and store data efficiently.

Technology Stack

• Frontend: Next.js, JavaScript
• Backend: PHP, InterPlanetary File System
• Databases: MySQL and other centralized and decentralized database solutions
• Blockchain: Smart contracts developed using Hardhat and OpenZeppelin, deployed on a blockchain platform

Installation

1. Clone the Repository

   git clone https://github.com/yourusername/nft-marketplace.git
   cd nft-marketplace

2. Install Dependencies

   npm install

3. Configure Environment Variables
