The NFT Trading Post is an on-chain, decentralized marketplace that facilitates peer-to-peer trading of Non-Fungible Tokens (NFTs). Built on Solidity, this smart contract allows users to list NFTs for sale and buy them securely without requiring third-party intermediaries.
NFT Listing: A seller can list an NFT by specifying the contract address, token ID, and desired price.
Buying NFTs: Buyers can purchase listed NFTs by sending the required payment.
Transaction Security: Upon a successful purchase, the smart contract transfers the funds to the seller and marks the listing as inactive.
Fully On-Chain Transactions: All NFT listings and sales are recorded on the blockchain, ensuring transparency.
Peer-to-Peer Trading: Direct exchange between buyers and sellers without centralized platforms.
Immutable & Trustless: Smart contract execution guarantees fair trades without relying on third-party trust.
Gas-Efficient & Minimalist Design: No unnecessary imports, constructors, or custom inputs—optimized for simplicity and performance.
This contract provides a foundation for NFT marketplaces and can be expanded with additional features like royalties, bidding systems, or advanced security measures.

Fraud Risks & Mitigation Strategies Fake Listings & Scams A malicious seller could list an NFT they don’t own or a counterfeit NFT. Mitigation: Implement ownership verification using ERC721.ownerOf(tokenId) before allowing a listing. Unauthorized Sales A seller might list an NFT without transferring ownership to the contract or buyer. Mitigation: The contract should require approval using IERC721(nftContract).transferFrom() to ensure legitimate transfers. Underpayment or Overpayment Exploits A buyer could attempt to manipulate the price or use incorrect payment amounts. Mitigation: Implement strict price checks in buyNFT() to prevent incorrect transactions.
