Broker an NFT Sale Using JavaScript

Earlier examples showed how to make buy and sell offers directly between two accounts. Another option is to use a third account as a broker for the sale. The broker acts on behalf of the NFT owner. The seller creates an offer with the broker account as its destination. The broker gathers and evaluates buy offers and chooses which one to accept, adding an agreed-upon fee for arranging the sale. When the broker account accepts a sell offer with a buy offer, the funds and ownership of the NFT are transferred simultaneously, completing the deal. This allows an account to act as a marketplace or personal agent for NFT creators and traders.

Usage

This example shows how to:

  1. Create a brokered sell offer.
  2. Get a list of offers for the brokered item.
  3. Broker a sale between two different accounts.

Quickstart form with Broker Account

You can download the Quickstart Samples archive to try each of the samples in your own browser.

Get Accounts

  1. Open 5.broker-nfts.html in a browser.
  2. Choose your ledger instance.
  3. Get test accounts.
    1. If you have existing account seeds:
      1. Paste 3 account seeds in the Seeds field.
      2. Click Get Accounts from Seeds.
    2. If you do not have account seeds:
      1. Click Get New Standby Account.
      2. Click Get New Operational Account.
      3. Click Get New Broker Account

Quickstart form with Account Information

Prepare a Brokered Transaction

  1. Use the Standby account to create an NFT Sell Offer with the Broker account as the destination.
    1. Enter the Amount of the sell offer in drops (millionths of an XRP).
    2. Set the Flags field to 1.
    3. Enter the NFT ID of the NFT you want to sell.
    4. Optionally, enter a number of days until Expiration.
    5. Enter the Broker account number as the Destination.
    6. Click Create Sell Offer.

Sell Offer with Destination

  1. Use the Operational account to create an NFT Buy Offer.
    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 days until Expiration.
    5. Click Create Buy Offer.

Buy Offer

Get Offers

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

Get Offers

Broker the Sale

  1. Copy the nft_offer_index of the sell offer and paste it in the Sell NFT Offer Index field.
  2. Copy the nft_offer_index of the buy offer and paste it in the Buy NFT Offer Index field.
  3. Enter a Broker Fee, in drops.
  4. Click Broker Sale.

Brokered Sale

Cancel Offer

After accepting a buy offer, a best practice for the broker is to cancel all other offers, if the broker has permissions to do so. Use Get Offers to get the full list of buy offers. To cancel an offer:

  1. Enter the nft_offer_index of the buy offer you want to cancel in the Buy NFT Offer Index field.
  2. Click Cancel Offer.

Code Walkthrough

You can download the Quickstart Samples archive to examine the code samples.

ripplex5-broker-nfts.js

This script has new functions for brokered transactions and revised functions to support a third account on the same screen.

Broker Get Offers

// *******************************************************
// *************** Broker Get Offers *********************
// *******************************************************
      
async function brGetOffers() {

Connect to the ledger.

  let net = getNet()
  const client = new xrpl.Client(net)
  results = 'Connecting to ' + getNet() + '...'
  brokerResultField.value = results
  await client.connect()
  results += '\nConnected. Getting offers...'
    brokerResultField.value = results

Request the list of sell offers for the token.

  results += '\n\n***Sell Offers***\n'  
  let nftSellOffers
  try {
    nftSellOffers = await client.request({
      method: "nft_sell_offers",
      nft_id: brokerTokenIdField.value  
    })
  } catch (err) {
    nftSellOffers = 'No sell offers.'
  }
  results += JSON.stringify(nftSellOffers,null,2)
    brokerResultField.value = results

Request the list of buy offers for the token.

  results += '\n\n***Buy Offers***\n'
  let nftBuyOffers
  try {
    nftBuyOffers = await client.request({
      method: "nft_buy_offers",

  }
  results += JSON.stringify(nftBuyOffers,null,2)    
    brokerResultField.value = results

Disconnect from the ledger.

  client.disconnect()  
}// End of brGetOffers()

Broker Sale

async function brokerSale() {

Connect to the ledger and get the accounts.

    const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
    const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)

    brokerResultField.value = results
    await client.connect()
    results += '\nConnected. Brokering sale...'
    brokerResultField.value = results

Prepare the transaction. The difference between a brokered sale and a direct sale is that you provide both a sell offer and a buy offer, with an agreed-upon broker's fee.

  const transactionBlob = {
    "TransactionType": "NFTokenAcceptOffer",
    "Account": broker_wallet.classicAddress,
    "NFTokenSellOffer": brokerTokenSellOfferIndexField.value,
    "NFTokenBuyOffer": brokerTokenBuyOfferIndexField.value,
    "NFTokenBrokerFee": brokerBrokerFeeField.value
  }

Submit the transaction and wait for the results.

  const tx = await client.submitAndWait(transactionBlob,{wallet: broker_wallet})

Report the results.

    results += "\n\nTransaction result:\n" + 
            JSON.stringify(tx.result.meta.TransactionResult, null, 2)
    results += "\nBalance changes:\n" +
            JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2)
    operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
    standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
    brokerBalanceField.value = (await client.getXrpBalance(broker_wallet.address))
    brokerResultField.value = results

Disconnect from the ledger.

  client.disconnect()
}// End of brokerSale()

Broker Cancel Offer

// *******************************************************
// ************* Broker Cancel Offer ****************
// *******************************************************

The Token ID must be converted to an array.

  const tokenOfferIDs = [brokerTokenBuyOfferIndexField.value]

Prepare the transaction.

  const transactionBlob = {
    "TransactionType": "NFTokenCancelOffer",
    "Account": wallet.classicAddress,
    "NFTokenOffers": tokenOfferIDs

      nft_id: brokerTokenBuyOfferIndexField.value })
  } catch (err) {
    nftBuyOffers = "No buy offers."
  }
  results += JSON.stringify(nftBuyOffers,null,2)

}// End of brCancelOffer()

Get Account

To accommodate the broker account, override the getAccount(type) function to watch for the broker type.

// ***************************************************************************
// ************** Revised Functions ******************************************
// ***************************************************************************

// *******************************************************
// ************* Get Account *****************************
// *******************************************************


async function getAccount(type) {

  } 
  if (type == 'operational') {
    operationalResultField.value = results
  }
  if (type == 'broker') {
    brokerResultField.value = results
  }

Create and fund a test account and report progress.

  const my_wallet = (await client.fundWallet(null, { faucetHost })).wallet

  results += '\nGot a wallet.'
  if (type == 'standby') {
    standbyResultField.value = results
  } 
  if (type == 'operational') {

  }

Get the XRP balance for the new account.

  const my_balance = (await client.getXrpBalance(my_wallet.address))

Populate the form fields for the appropriate account with the new account information.

  if (type == 'standby') {
    standbyAccountField.value = my_wallet.address
    standbyPubKeyField.value = my_wallet.publicKey

    brokerBalanceField.value = (await client.getXrpBalance(my_wallet.address))
    results += '\nBroker account created.'
    brokerResultField.value = results
  }

Add the new account seed to corresponding line in the Account Seeds field.

  seeds.value = standbySeedField.value + '\n' + operationalSeedField.value + "\n" +
    brokerSeedField.value

Disconnect from the ledger.

  client.disconnect()
} // End of getAccount()

Get Accounts from Seeds

Override the getAccountsFromSeeds() function to include the broker account fields.

    brokerPrivKeyField.value = broker_wallet.privateKey
    brokerSeedField.value = broker_wallet.seed
    brokerBalanceField.value = (await client.getXrpBalance(broker_wallet.address))

Disconnect from the ledger.

  client.disconnect()

Use the getBalances() function to get the current balances of fiat currency.
