NFT Marketplace on Aptos Blockchain

Built on the Aptos blockchain using the Move programming language, this marketplace enables users to mint, list, bid on, and trade NFTs with full on-chain logic. The smart contract handles auctions with time-based expiry, royalty enforcement on every secondary sale (5% default, 15% max), batch NFT transfers, an offer/counter-offer system, and a creator tipping mechanism — all paid in APT tokens. The React frontend connects via Petra Wallet.
