English Auction NFT Smart Contract

This smart contract is an implementation of an English auction for non-fungible tokens (NFTs) on the Ethereum blockchain. In an English auction, the seller sets a starting price, and buyers bid successively higher prices until no higher bid is offered, at which point the highest bidder wins the NFT.

Auction

  • Seller of NFT deploys this contract.
  • Auction lasts for specific time.
  • Participants can bid by depositing ETH greater than the current highest bidder.
  • All bidders can withdraw their bid if it is not the current highest bid.

After the auction

  • Highest bidder becomes the new owner of NFT.
  • The seller receives the highest bid of ETH.
