As a seller, you confirm the price for your NFT when creating the listing. This is the price at which you are agreeing to allow buyers to purchase that NFT using crypto or fiat payment methods.
When a buyer selects either payment option during checkout, RECUR sends a request to the applicable payment processor to process the payment. While the request is in progress, the NFT is removed from the marketplace and reserved. Should the payment not be received in time or the payment fail, the NFT will be relisted on behalf of the seller at the original listing price.
