x/marketplace

The marketplace module allows users to list NFTs with a fixed price or through timed auctions. Buyers can purchase NFTs from the marketplace by paying the listed price or by participating in an auction. The marketplace module supports different types of listings:

  • Fixed Price Listing
  • Timed Auction
Fixed Price Listing

In a fixed price listing, buyers must pay the listed amount to acquire the NFT. NFT owners can list their NFT with any allowed token and specify split shares between different addresses and the percentage of revenue each address receives.

message Listing {
  string                   id       = 1;

    (gogoproto.nullable)   = false
  ];
}

Timed Auction

  • Timed auction require buyers to bid with a minimum amount.
  • Only one bid is allowed at a time in these auctions.
  • When a new bid is placed, the previous bid amount will be returned to the bidder.
  • Auction will end at the end time and the highest bidder will be the winner.
  • if no bids were placed on the auction, it will be closed at end time.`

Fees and Distribution

Whenever an NFT is bought or an auction is concluded, a certain percentage of the sale amount is collected as a commission. This commission is then distributed among different parties based on the distribution parameters that have been set.

  • Staking distribution: The percentage of the fee that is distributed to stakers.
  • Community pool distribution: The percentage of the fee that is added to the community pool.

State

The state of the module is expressed by following fields

  1. listings: A list of NFT listings that are available in the marketplace.
  2. ListingCount: The total count of NFT listings.
  3. params: Marketplace module parameters.
  4. auctions: A list of active auctions in the marketplace.
  5. bids: A list of bids made on auctions.
  6. next_auction_number: The number to be assigned to the next auction that is created.

  uint64                  next_auction_number = 6;
}
Module parameters

The Marketplace module includes the following parameters:

  • Sale commission: A decimal that represents the percentage of the sale price that is collected as a fee. This fee is distributed to various parties according to the configured distribution parameters.
  • Distribution: A data structure that represents the distribution of the sale commission. It includes two fields: the staking distribution and the community pool distribution. These fields are represented as decimals and represent the percentage of the sale commission that is distributed to each party.
  • Bid close duration: A duration that represents the amount of time after the last bid was placed before the auction is closed. If no bids were placed on the auction, it will be closed after this duration.
