NFTokenCreateOffer

Non-fungible token functionality is part of the NonFungibleTokensV1 amendment to the XRP Ledger protocol. You can use these functions on the NFT-Devnet now, but they are not yet available on the production Mainnet.

Creates either a new Sell offer for an NFToken owned by the account executing the transaction, or a new Buy offer for an NFToken owned by another account.

If successful, the transaction creates a NFTokenOffer object. Each offer counts as one object towards the owner reserve of the account that placed the offer.

Example NFTokenCreateOffer JSON

{
    "TransactionType": "NFTokenCreateOffer",
    "Account": "rs8jBmmfpwgmrSPgwMsh7CvKRmRt1JTVSX",
    "NFTokenID": "000100001E962F495F07A990F4ED55ACCFEEF365DBAA76B6A048C0A200000007",
    "Amount": "1000000",
    "Flags": 1
}

NFTokenCreateOffer Fields

In addition to the common fields, a NFTokenCreateOffer transaction uses the following fields:

Field	JSON Type	Internal Type	Description
`Owner`	String	AccountID	(Optional) Who owns the corresponding `NFToken`. If the offer is to buy a token, this field must be present and it must be different than the `Account` field (since an offer to buy a token one already holds is meaningless). If the offer is to sell a token, this field must not be present, as the owner is, implicitly, the same as the `Account` (since an offer to sell a token one doesn't already hold is meaningless).
`NFTokenID`	String	Hash256	Identifies the `NFToken` object that the offer references.
`Amount`	Currency Amount	Amount	Indicates the amount expected or offered for the corresponding `NFToken`. The amount must be non-zero, except where this is an offer to sell and the asset is XRP; then, it is legal to specify an amount of zero, which means that the current owner of the token is giving it away, gratis, either to anyone at all, or to the account identified by the `Destination` field.
`Expiration`	Number	UInt32	(Optional) Indicates the time after which the offer will no longer be valid. The value is the number of seconds since the Ripple Epoch.
`Destination`	String	AccountID	(Optional) If present, indicates that this offer may only be accepted by the specified account. Attempts by other accounts to accept this offer MUST fail.

NFTokenCreateOffer Flags

Transactions of the NFTokenCreateOffer type support additional values in the Flags field, as follows:

Flag Name	Hex Value	Decimal Value	Description
`tfSellNFToken`	`0x00000001`	`1`	If enabled, indicates that the offer is a sell offer. Otherwise, it is a buy offer.

Error Cases

In addition to errors that can occur for all transactions, NFTokenCreateOffer transactions can result in the following transaction result codes:

Error Code	Description
`temDISABLED`	The NonFungibleTokensV1 amendment is not enabled.
`temBAD_AMOUNT`	The `Amount` field is not valid. For example, the amount was zero for a buy offer, or the amount is denominated in fungible tokens but the `NFToken` has the `lsfOnlyXRP` flag enabled.
`temBAD_EXPIRATION`	The specified `Expiration` time is invalid (for example, `0`).
`tecDIR_FULL`	The sender already owns too many objects in the ledger, or there are already too many offers to buy or sell this token.
`tecEXPIRED`	The specified `Expiration` time has already passed.
`tecFROZEN`	The `Amount` is denominated in fungible tokens, but one of the trust lines that would receive tokens from this offer is frozen. This could be the seller's trust line or the `NFToken`'s issuer's trust line (if the `NFToken` has a transfer fee).
`tecINSUFFICIENT_RESERVE`	The sender does not have enough XRP to meet the reserve requirement after placing this offer.
`tecNO_DST`	The account specified in the `Destination` field does not exist in the ledger.
`tecNO_ENTRY`	The `NFToken` is not owned by the expected account.
`tecNO_ISSUER`	The issuer specified in the `Amount` field does not exist.
`tecNO_LINE`	The `Amount` field is denominated in fungible tokens, but the `NFToken`'s issuer does not have a trust line for those tokens and the `NFToken` does not have the `lsfTrustLine` flag enabled.
`tecUNFUNDED_OFFER`	For a buy offer, the sender does have the funds specified in the `Amount` field available. If the `Amount` is XRP, this could be due to the reserve requirement; if the `Amount` is denominated in fungible tokens, this could be because they are frozen.
`tefNFTOKEN_IS_NOT_TRANSFERABLE`	The `NFToken` has the `lsfTransferable` flag disabled and this transaction would not transfer the `NFToken` to or from the issuer.
