Auction Listing: An auction listing will present a single NFT for auction-style bidding.
Purchase Listing: A purchase listing is a set price listing. Multiple editions of an NFT can also be listed in a purchase listing.
A listing can be configured with the following parameters on creation:
Start Time:(Optional) parameter for the time a listing becomes active and will accept bid or purchase requests. If this parameter is not provided, the sale will start on first bid or purchase.
End Time:(Optional) parameter for the time a listing expires and will no longer accept bid or purchase requests. If the start time is not provided, this value represents the duration, in seconds, the listing will be active.
Floor Price: For Auction listings, this acts as the minimum initial bid. For Purchase listings, this is the price to purchase the NFT.
ERC20 Token Address:(Optional) provide this address if you wish to sell the NFT using an ERC20 token
Minimum Basis Points Increment:(Auctions Only) the minimum increment between bids
Extension Interval:(Auctions Only) the amount of time to extend the auction if a bid comes in within this interval's time remaining. See extended bidding
Identity Verifier Address:(Optional) provide this address if you wish to use a smart contract to restrict bid/purchase access to the listing. An Identity Verifier Address must implement the IIdentityVerifier interface.
