Overview

This project consists of two main smart contracts:

1. NFT Contract: Implements ERC721 standard for minting NFTs.
2. NFT Marketplace Contract: Allows users to list, buy, and make offers on NFTs.

Key Functions:

• mint(address to, string memory tokenURI): Mints a new NFT.
• tokenURI(uint256 tokenId): Returns the metadata of a given token ID.

NFT Marketplace Contract

This contract allows users to list NFTs for sale, buy listed NFTs, make offers on listed NFTs, and cancel listings. It also supports adding and withdrawing funds.

Key Functions:

• listNFT(address nftAddress, uint256 tokenId, uint256 price): Lists an NFT for sale.
• buyNFT(address nftAddress, uint256 tokenId): Buys a listed NFT.
• makeOffer(address nftAddress, uint256 tokenId): Makes an offer on a listed NFT.
• acceptOffer(address nftAddress, uint256 tokenId, uint256 offerIndex): Accepts an offer on a listed NFT.
• cancelListing(address nftAddress, uint256 tokenId): Cancels a listing.
• addFunds(): Adds funds to the user's account.
• withdrawFunds(): Withdraws funds from the user's account.
