Auction

List your artwork as an English auction with configurable bidding options and anti-sniping protection.

Auction lifecycle
Bids decide the final price
  1. Set termsReserve, increment, start, and duration
  2. Collectors bidEach bid beats the last by your increment
  3. Auction endsThe highest bidder wins
  4. SettleEither side settles: art to the winner, proceeds to you
An optional end phase extends the auction when a bid lands near the deadline.

What are Auctions?

Auctions follow the traditional English auction format where collectors compete by placing increasingly higher bids on your artwork. Unlike fixed-price sales, auctions create competitive bidding environments that can drive prices above your initial expectations. The highest bidder when the auction ends wins the artwork.

This page is for sellers. Bidding covers the same auction from the collector's side.

Key Features

  • Competitive Bidding

    English auction format where each bid must exceed the previous bid by your configured increment.

  • Anti-Sniping Protection

    Optional end phase extends auction time when bids are placed near the deadline, ensuring fair competition.

  • Reserve Price Protection

    Set a minimum acceptable price that the first bid must meet. An On bid auction starts when a bid meets it, and a scheduled auction that never gets one ends with no winner.

  • Flexible Start Options

    Start immediately on first bid or schedule for a specific date and time.

  • Physical Integration

    Optionally include a physical artwork with unlock pricing and shipping address collection.

Auction Start Configuration

  • On bid - Auction starts immediately when the first bid is placed
  • Scheduled start - Start immediately or set a future date and time for your auction to begin (all times are in your local timezone)

Reserve Price Settings

  • Currency: Choose between SOL, USDC, or other supported tokens
  • Reserve price: Enter the minimum amount you're willing to accept

Bid Increment Configuration

  • Increment type: Choose between percentage (%) or fixed amount
  • Percentage increment: Each bid must be at least this % higher than the previous bid
  • Fixed amount: Alternative option for a static token amount increases

Auction Duration

How long do you want your auction to run?

End Phase Configuration

Setting an end phase will extend your auction with each bid within the given time frame from the end of the auction. This prevents users from "sniping" your auction at the last second, allowing for other bidders to increase their bid.

  • None - Auction ends exactly at the scheduled time
  • Timed - Any bid placed within the end phase moves the end time to the bid time plus the end phase. For example, an auction set to end at 2:00 PM has a 5-minute end phase. A bid at 1:57 PM falls inside that window, so the auction now ends at 2:02 PM, 5 minutes after the bid. Each later bid inside the window extends it again.
Anti-sniping end phaseEnds 2:00 PM

A bid at 1:57 PM is inside the end phase, so the end moves to 1:57 PM + 5 min = 2:02 PM.

End phase

Drag the marker or use the arrow keys to choose when the next bid lands. Only a bid inside the end phase extends the auction, and the new end is the bid time plus the end phase.

Physical Artwork

  • Include physical artwork with sale - Check this if you're selling a physical piece along with the NFT
    • Describe any pertinent shipping details the collector should know about
    • Optionally upload a photo of the physical piece to show collectors what they're getting
  • Unlock price - Specify an unlock price for the physical (bid amounts below this do not receive the physical)
  • Ask buyer for shipping address - Check this if you want the winner of the auction to send you their shipping address through mallow.

Physicals explains the unlock price, how the address reaches you, and what you're responsible for.
