What is NFT Auction?

NFT auctions are a sale process where owners or developers list specifically non-fungible tokens for sale to interested buyers. Subsequently, buyers could place their bids on the auction according to the price at which they want to buy the NFT. It is important to ensure that the bid is higher than the minimum price established by the seller. When the auction ends, the listed NFT will be sold to the highest bidder.

Auctions work by putting up an item for sale alongside setting a minimum price and a specific period for sale. Buyers have to place their bids on the concerned item according to the price they want to pay for the item. When the auction ends, the highest bidder could buy the item at the price they bid for it.
