How do you put an NFT up for auction?

Setting Up Your Digital Wallet for NFT Auctions

1. Choose a blockchain-compatible wallet such as MetaMask, Trust Wallet, or Phantom depending on the network you're using—Ethereum, Binance Smart Chain, or Solana.

2. Install the wallet extension or app and securely store your seed phrase in a physical, offline location.
3. Fund your wallet with the native cryptocurrency required by the blockchain—ETH for Ethereum, SOL for Solana, etc.
4. Connect your wallet to an NFT marketplace like OpenSea, Rarible, or Magic Eden by clicking the 'Connect Wallet' button on their site.
5. Confirm the connection through your wallet interface and ensure your public address appears correctly on the platform.

Uploading and Minting Your NFT

1. Navigate to the 'Create' or 'Sell' section of your chosen marketplace after connecting your wallet.

2. Upload your digital file—image, video, audio, or 3D model—ensuring it meets the size and format requirements.
3. Enter metadata including title, description, properties, and unlockable content if applicable.
4. Select whether to mint your NFT as a single item or create multiple editions.
5. Click 'Create' or 'Mint,' which will prompt a transaction confirmation in your wallet; approve it and pay the associated gas fees.

Successfully minted NFTs become part of your collection and are ready for auction setup.

Configuring the Auction Terms

1. Locate your newly minted NFT in your profile’s collection and select the option to 'List' or 'Sell.'

2. Choose the auction type—either a timed auction with a start and end time or a declining-price Dutch auction.
3. Set the starting bid, reserve price (if desired), and duration of the auction, typically ranging from one day to one week.
4. Decide whether bids require approval or can be placed automatically by any user.
5. Review all details carefully, then confirm the listing; this action generates another blockchain transaction requiring wallet approval and gas payment.

Managing Bids and Finalizing the Sale

1. Monitor incoming bids through the marketplace dashboard or receive notifications if enabled.

2. Engage with potential buyers via comments or social media links attached to your NFT listing.
3. When the auction ends, the highest bidder is automatically declared the winner if the reserve price was met.
4. The platform executes the transfer of the NFT to the buyer’s wallet and deposits the proceeds into your wallet minus service fees.
5. Withdraw funds or reinvest them directly on the platform for future projects or purchases.

Frequently Asked Questions

What happens if the reserve price isn’t met during the auction?If no bid reaches the reserve price, the seller retains ownership of the NFT. The highest bidder may still have the option to purchase at their offered amount if the seller chooses to accept it manually.

Can I cancel an auction once it has started?Most platforms do not allow cancellation of active auctions to maintain trust and fairness. However, some marketplaces let sellers refuse the final bid if a reserve price wasn't set or met.

Are there royalties involved when selling an NFT at auction?Yes, creators can set a royalty percentage during minting. This ensures they receive a portion of the sale price each time the NFT changes hands, enforced automatically by smart contracts.

How are gas fees determined during the auction process?Gas fees depend on network congestion and transaction complexity. Ethereum tends to have higher fees during peak times, while blockchains like Polygon or Solana offer lower-cost alternatives for minting and listing.
