NFT Auction DApp

This decentralized application (DApp) allows users to create and participate in auctions for non-fungible tokens (NFTs). Users can list their NFTs for auction, specify the minimum price and auction duration, and other users can bid on the listed NFTs. The highest bidder at the end of the auction period wins the NFT.

• List NFTs for Auction: Users can list their NFTs for auction by providing the NFT, minimum price, and auction duration.
• Place Bids: Users can place bids on the listed NFTs by specifying the auction ID and the bid amount.

• Withdraw Funds: The auction owner can withdraw the highest bid amount after the auction ends.
