Unlike a fixed-price listing, the final sale price is determined by competitive bidding, useful for high-value or rare NFTs where market demand is unknown. *** ### Creating an Auction Go to **My Profile**, open the NFT you want to auction, and click **Start Auction**. Fill in the following fields: * **Start date** — When bidding opens. Can be immediate or scheduled. * **End date** — When bidding closes. No bids are accepted after this time. * **Starting price** — The minimum bid required to start the auction. * **Reserve price** *(optional)* — A hidden minimum. If the highest bid does not reach this amount, the auction ends without a sale.
Check the **Terms of Service** box and click **Create Auction**. Confirm the transaction in your wallet to publish the listing. *** ### How Bidding Works Once the auction is live, any connected wallet can place a bid. Each new bid must exceed the current highest bid. Bids are visible in the **Bids** section on the NFT detail page, showing bidder address, amount, and timestamp. Funds are held on-chain for the duration of the auction. Outbid participants can reclaim their funds once they are no longer the highest bidder.
