In this project, I build the NFT-Marketplace on which users can buy, sell and upload their own NFTs. I write smart contracts using Solidity language and uploaded all NFTs on PINATA, an IPFS platform. I use Hardhat to deploy my contract. In the frontend interface, I use ReactJs. In these projects, I learned how to write smart contracts, deploy web3 applications, and use of testnets and faucets for your projects.
