PROJECT
Develop Smart Contract for NFT Marketplace
In this project, we’ll learn how to develop a smart contract for an NFT marketplace using Ethereum, Solidity, and Hardhat.
You will learn to:
Develop Ethereum smart contracts using Hardhat and OpenZeppelin.
List NFTs in the marketplace for sale.
Mint and trade NFTs.
Deploy smart contracts.

Project Description
This project is built on the Ethereum blockchain that enables users to mint, list, and trade non-fungible tokens (NFTs). The smart contract is written in Solidity, utilizing the ERC721 token standard for unique token identification.
We’ll utilize the Hardhat framework to develop the smart contract. By using this technology, we can easily develop, test, and deploy the contracts. We’ll also use OpenZeppelin, a widely recognized library of reusable and secure smart contract components in our project.
The key features that this project will contain are as follows:
-
Minting: Users can create and mint new NFTs by providing a token URI and setting an initial price for the NFT.
-
Listing: NFTs can be listed for sale at a specified price. A listing fee is required for listing an NFT on the marketplace.
-
Buying: Users can purchase listed NFTs by sending the required payment, transferring the ownership of the NFT to the buyer, and providing the necessary fees to the contract owner.
-
Retrieving: Users can retrieve a list of all NFTs available on the marketplace and view their personal collection of NFTs.
