Auction in Marketplace

An auction is a feature that makes it possible for people to bid for a certain period of time. The highest/last bid during the auction period will get you the NFT you want.

All users can participate in the auction provided that the balance in the wallet meets the desired number of bids.

Auction NFT Rules


  • Each bid must be at least 5% higher than its previous bid.

  • A certain percentage of tokens (5%) of each bid is distributed to the previous bidder, except for the first bid because there were no previous bidders.

  • When a new bid is placed above the old bid, the old bid is canceled and the margin token is returned to the old bid. The remaining 95% of the bid is returned, plus 5% of the new bid, and the Token will be returned to the bidder's wallet immediately.

Example : If you start bid at 1000 $XRAI and then get outbidded at 1200 $XRAI

  • If you are the first bidder (there are no bids before you) you will get back 1000 $XRAI + 60 $XRAI (1200 x 5%) back when outbidded.

  • If you outbid your previous bid, you'll get 950 $XRAI (10 × 95%) + 60 $XRAI (1200 × 5%) back when outbidded.

Time Bid

  • Each bidding session will have a fixed time decided by the bid opener. Bidding time will count down when the end to 0, and the auction ends. NFTs will be claimed by either the winner of the bid (the last bidder) or the seller.

  • When there is a new bid and the countdown to the end time is less than 5 minutes, the bid time will be extended by 5 minutes.

  • The auction can be canceled at any time by the auction item seller when no user has entered the auction.

  • The auction is canceled when there are no bidders.

  • The bid cannot be canceled once a user has entered the bid.

Collect NFTs and bid fees

  • After the auction ends with the final bid, the seller or bidder can click the "Claim" button on the NFT detail page to complete the receipt of the NFTs and payment for the NFTs.

  • A fee of 5% of the last bid will be used as the market fee. Will use awarded to users holding $XRAI tokens.
