Form with account information

Create a Sell Offer

To create a NFT sell offer:

  1. Enter the Amount of the sell offer in drops (millionths of an XRP).
  2. Enter the NFT ID of the NFT you want to sell.
  3. Optionally, enter a Destination account, the only account that can accept the offer.
  4. Optionally, enter a number of seconds until Expiration.
  5. Click Create Sell Offer.
  6. Click Get Offers.

The important piece of information in the response is the NFT Offer Index, labeled as nft_offer_index, which you use to accept the sell offer.

NFT Sell Offer

Accept Sell Offer

Once a sell offer is available, another account can opt to accept the offer and buy the NFT.

To accept an available sell offer:

  1. Enter the NFT Offer Index (labeled as nft_offer_index in the token offer results. This is different from the NFTokenID.)
  2. Click Accept Sell Offer.
  3. Click Get Standby Account Info and Get Op Account Info to update the XRP balances.
  4. Click Get NFTs for each account to see that the NFT has moved from the Standby account to the Operational account.

Accept Sell Offer

Create a Buy Offer

You can offer to buy an NFT from another account.

To create an offer to buy an NFT:

  1. Enter the Amount of your offer.
  2. Enter the NFT ID.
  3. Enter the owner’s account string in the Owner field.
  4. Optionally enter the number of seconds until Expiration.
  5. Click Create Buy Offer.
  6. On the Operational side, enter the NFT ID.
  7. Click Get Offers to view the offer and copy the nft_offer_index.

NFT Buy Offer

Accept a Buy Offer

To accept an offer to buy an NFT:

  1. Enter the NFT Offer Index (the nft_offer_index of the NFT buy offer).
  2. Click Accept Buy Offer.
  3. Click Get Standby Account Info and Get Op Account Info to update the XRP balances.
  4. Click Get NFTs for both accounts to see that the NFT has moved from the Operational account to the Standby account.

Accept Buy Offer

Get Offers

To list the buy and sell offers associated with an NFT:

  1. Enter the NFT ID.
  2. Click Get Offers.

Get offers

Cancel Offer

To cancel a buy or sell offer that you have created:

Create Sell Offer

Pass the arguments seed, amount, NFT ID, expiration (in seconds, optional), and destination (optional).

def create_sell_offer(seed, amount, nftoken_id, expiration, destination):
    """create_sell_offer"""

Get the owner wallet and create a client connection.

    owner_wallet = Wallet.from_seed(seed)
    client = JsonRpcClient(testnet_url)

If there is an expiration value, convert the current date and time to Ripple time, then add the expiration value.

    expiration_date = datetime.now()
    if expiration != '':
        expiration_date = xrpl.utils.datetime_to_ripple_time(expiration_date)
        expiration_date = expiration_date + int(expiration)

Define the sell offer transaction.

    sell_offer_tx=xrpl.models.transactions.NFTokenCreateOffer(
        account=owner_wallet.address,
        nftoken_id=nftoken_id,
        amount=amount,

If the sale is designated for a specific destination account, include the destination argument.

        destination=destination if destination != '' else None,

If the expiration date is present, include the expiration argument.

        expiration=expiration_date if expiration != '' else None,

Set the flags value to 1, indicating that this is a sell offer.

        flags=1
    )

Submit the transaction.

    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(sell_offer_tx,client,owner_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"

Return the result.

    return reply

Accept Sell Offer

Pass the buyer's seed value and the NFT sell offer index.

def accept_sell_offer(seed, offer_index):
    """accept_sell_offer"""

Get the wallet and a client instance.

    buyer_wallet=Wallet.from_seed(seed)
    client=JsonRpcClient(testnet_url)

Define the accept offer transaction

    accept_offer_tx=xrpl.models.transactions.NFTokenAcceptOffer(
       account=buyer_wallet.classic_address,
       nftoken_sell_offer=offer_index
    )

Sign and fill the transaction.

    signed_tx=xrpl.transaction.safe_sign_and_autofill_transaction(
        accept_offer_tx, buyer_wallet, client)

Submit the transaction and report the results.

    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(accept_offer_tx,client,buyer_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply

Create Buy Offer

Pass the buyer seed, amount, NFT ID, owner, expiration (in seconds, optional), and destination account (optional).

def create_buy_offer(seed, amount, nft_id, owner, expiration, destination):
    """create_buy_offer"""

Get the buyer wallet and a client instance.

    buyer_wallet=Wallet.from_seed(seed)
    client=JsonRpcClient(testnet_url)

If the expiration value is present, get the current date and time, convert it to Ripple time, and add the expiration value.

    expiration_date=datetime.now()
    if (expiration!=''):
        expiration_date=xrpl.utils.datetime_to_ripple_time(expiration_date)
        expiration_date=expiration_date + int(expiration)

Define the buy offer transaction.

    buy_offer_tx=xrpl.models.transactions.NFTokenCreateOffer(
        account=buyer_wallet.address,
        nftoken_id=nft_id,
        amount=amount,
        owner=owner,

IF the expiration value is present, include the expiration argument.

        expiration=expiration_date if expiration!='' else None,

If the destination value is present, include the destination argument.

        destination=destination if destination!='' else None,

Set the flags value to 0, indicating that this is a "buy" offer.

        flags=0
    )

Submit the transaction and report the results.

    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(buy_offer_tx,client,buyer_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply

Accept Buy Offer

Pass the buyer's seed value and the NFT offer___index.

def accept_buy_offer(seed, offer_index):
    """accept_buy_offer"""

Get the buyer wallet and a client instance.

    buyer_wallet=Wallet.from_seed(seed)
    client=JsonRpcClient(testnet_url)

Define the accept offer transaction.

    accept_offer_tx=xrpl.models.transactions.NFTokenAcceptOffer(
       account=buyer_wallet.address,
       nftoken_buy_offer=offer_index
    )

Submit the transaction and report the results

    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(accept_offer_tx,client,buyer_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply

Get Offers

This is a request, rather than a transaction, so there is no need for a wallet.

Pass the NFT ID.

def get_offers(nft_id):
    """get_offers"""

Create a client instance.

    client=JsonRpcClient(testnet_url)

Define the request for buy offers.

    offers=NFTBuyOffers(
        nft_id=nft_id
    )

Send the request and capture the response.

    response=client.request(offers)

Create the allOffers variable to accumulate the offer responses.

    allOffers="Buy Offers:\n"+json.dumps(response.result, indent=4)

Define the request for sell offers.

    offers=NFTSellOffers(
        nft_id=nft_id
    )

Send the request and capture the response.

    response=client.request(offers)

Add the response to the allOffers variable and return the results.

    allOffers+="\n\nSell Offers:\n"+json.dumps(response.result, indent=4)
    return allOffers

Cancel Offer

The creator of an offer can cancel it at any time before it is accepted. Anyone can cancel and offer if its expiration data has expired.

Pass the seed and the NFT Offer ID to be canceled.

def cancel_offer(seed, nftoken_offer_ids):
    """cancel_offer"""

Get the wallet and a client instance.

    owner_wallet=Wallet(seed, sequence=16237283)
    client=JsonRpcClient(testnet_url)

The nftoken_offers parameter is an array, rather than a single ID. You can revise the code to accept several offer IDs at one time. Here, the value is added to a new array variable.

    tokenOfferIDs=[nftoken_offer_ids]

Define the cancel offer transaction.

    nftSellOffers="No sell offers"
    cancel_offer_tx=xrpl.models.transactions.NFTokenCancelOffer(
                account=owner_wallet.classic_address,
                nftoken_offers=tokenOfferIDs
        )

Submit the transaction and return the result.

    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(cancel_offer_tx,client,owner_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
