Sell offers that specify assets other than XRP must specify a non-zero amount. Sell offers that specify XRP can be 'free' (that is, the Amount field can be equal to "0").
DestinationstringAccountIDNoThe AccountID for which this offer is intended. If present, only that account can accept the offer.
ExpirationnumberUInt32NoThe time after which the offer is no longer active. The value is the number of seconds since the Ripple Epoch.
LedgerEntryTypestringUInt16YesThe value 0x0037, mapped to the string NFTokenOffer, indicates that this is an offer to trade a NFToken.
NFTokenIDstringHash256YesThe NFTokenID of the NFToken object referenced by this offer.
NFTokenOfferNodestringUInt64NoInternal bookkeeping, indicating the page inside the token buy or sell offer directory, as appropriate, where this token is being tracked. This field allows the efficient deletion of offers.
OwnerstringAccountIDYesOwner of the account that is creating and owns the offer. Only the current Owner of an NFToken can create an offer to sell an NFToken, but any account can create an offer to buy an NFToken.

NFTokenOffer Transactions

Unlike Offers for fungible tokens, a NFTokenOffer is not stored in an order book and is never automatically matched or executed. A buyer must explicitly choose to accept an NFTokenOffer that offers to sell a NFToken. Similarly, a seller must explicitly choose to accept a specific NFTokenOffer that offers to buy a NFToken object that they own.

The transactions for NFToken trading are:

Locating NFTokenOffer entries

Each unique NFT has up to two directories: one contains offers to buy the token and the other contains offers to sell the token. (These two directories are created as necessary and deleted if empty.) Marketplaces or other client applications can use these directories to find and display offers to trade NFToken objects to users or even automatically match them and accept them.

NFTokenOffer Reserve

NFTokenOffer entries each count as one item towards the owner reserve of the account placing the offer, as long as the entry is in the ledger. Accepting or canceling the offer frees up the reserve.

NFTokenOffer ID Format

The unique ID (NFTokenOfferID) of a NFTokenOffer object is the result of the following values concatenated in order:

  • The NFTokenOffer space key, 0x0037;
  • The AccountID of the account placing the offer; and
  • The Sequence (or Ticket) of the NFTokenCreateOffer transaction that created the NFTokenOffer.
