1. Create Accounts and Send XRP

This example shows how to:

  1. Create accounts on the Testnet, funded with 10000 test XRP with no actual value.
  2. Retrieve the accounts from seed values.
  3. Transfer XRP between accounts.

When you create an account, you receive a public/private key pair offline. It does not appear on the ledger until it is funded with XRP. This example shows how to create accounts for Testnet, but not how to create an account that you can use on Mainnet.

Token Test Harness

Prerequisites

To get started, create a new folder on your local disk and install the JavaScript library using npm.

    npm install xrpl

Download and expand the Quickstart Samples archive.

Usage

To get test accounts:

  1. Open 1.get-accounts-send-xrp.html in a browser
  2. Choose NFT-Devnet, Testnet, or Devnet.
  3. Click Get New Standby Account.
  4. Click Get New Operational Account.
  5. Copy and paste the Seeds field in a persistent location, such as a Notepad, so that you can reuse the accounts after reloading the form.

Standby and Operational Accounts

You can transfer XRP between your new accounts. Each account has its own fields and buttons.

To transfer XRP between accounts:

  1. Enter the Amount of XRP to send.
  2. Enter the Destination account (for example, copy and paste the Operational Account Field to the Standby Destination field).
  3. Click Send XRP> to transfer XRP from the standby account to the operational account, or <Send XRP to transfer XRP from the operational account to the standby account.

Code Walkthrough

You can download the Quickstart Samples in the source repository for this website.

ripplex-1-send-xrp.js

This example can be used with any XRP Ledger network. Currently, there are Testnet and Devnet, with the experimental NFT-Devnet server with support for NFTokens. You can update the code to choose different or additional XRP Ledger networks.

getNet()

// ******************************************************
// ************* Get the Preferred Network **************
// ******************************************************   

    function getNet() {

This function uses brute force if statements to discover the selected network instance and return the URI.

        let net
          if (document.getElementById("xls").checked) net = "wss://xls20-sandbox.rippletest.net:51233"
          if (document.getElementById("tn").checked) net = "wss://s.altnet.rippletest.net:51233"
          if (document.getElementById("dn").checked) net = "wss://s.devnet.rippletest.net:51233"
          return net
        } // End of getNet()

getAccount(type)

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


  async function getAccount(type) {

Get the selected ledger.

      let net = getNet()

Instantiate a client.

      const client = new xrpl.Client(net)

Use the results variable to capture progress information.

        results = 'Connecting to ' + getNet() + '....'
        const walletServer = net

Report progress in the appropriate results field.

        if (type == 'standby') {
          document.getElementById('standbyResultField').value = results
        } else {
          document.getElementById('operationalResultField').value = results
        }

Connect to the server.

        await client.connect()


        results += '\nConnected, funding wallet.'
        if (type == 'standby') {
          document.getElementById('standbyResultField').value = results
        } else {
          document.getElementById('operationalResultField').value = results
        }

Create and fund a test account wallet.

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

Get the current XRP balance for the account.

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

If this is a standby account, populate the standby account fields.

        if (type == 'standby') {
          document.getElementById('standbyAccountField').value = my_wallet.address
          document.getElementById('standbyPubKeyField').value = my_wallet.publicKey
          document.getElementById('standbyPrivKeyField').value = my_wallet.privateKey
          document.getElementById('standbyBalanceField').value = 
              (await client.getXrpBalance(my_wallet.address))
          document.getElementById('standbySeedField').value = my_wallet.seed
          results += '\nStandby account created.'
          document.getElementById('standbyResultField').value = results

Otherwise, populate the operational account fields.

        } else {
          document.getElementById('operationalAccountField').value = my_wallet.address
          document.getElementById('operationalPubKeyField').value = my_wallet.publicKey
          document.getElementById('operationalPrivKeyField').value = my_wallet.privateKey
          document.getElementById('operationalSeedField').value = my_wallet.seed
          document.getElementById('operationalBalanceField').value = 
              (await client.getXrpBalance(my_wallet.address))
          results += '\nOperational account created.'
          document.getElementById('operationalResultField').value = results
        }

Insert the seed values for both accounts as they are created to the Seeds field as a convenience. You can copy the values and store them offline. When you reload this form or another in this tutorial, copy and paste them into the Seeds field to retrieve the accounts with the getAccountsFromSeeds() function.

        document.getElementById('seeds').value = standbySeedField.value + '\n' + operationalSeedField.value

Disconnect from the XRP ledger.

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

Get Accounts from Seeds

// *******************************************************
// ********** Get Accounts from Seeds ******************** 
// *******************************************************

      async function getAccountsFromSeeds() {

Connect to the selected network.

        let net = getNet()
        const client = new xrpl.Client(net)
        results = 'Connecting to ' + getNet() + '....'
        document.getElementById('standbyResultField').value = results
        await client.connect()
        results += '\nConnected, finding wallets.\n'
        document.getElementById('standbyResultField').value = results

Parse the Seeds field.

        var lines = seeds.value.split('\n');

Get the standby_wallet based on the seed in the first line. Get the operational_wallet based on the seed in the second line.

        const standby_wallet = xrpl.Wallet.fromSeed(lines[0])
        const operational_wallet = xrpl.Wallet.fromSeed(lines[1])

Get the current XRP balances for the accounts.

        const standby_balance = (await client.getXrpBalance(standby_wallet.address))  
        const operational_balance = (await client.getXrpBalance(operational_wallet.address))  

Populate the fields for the standby and operational accounts.

        document.getElementById('standbyAccountField').value = standby_wallet.address
        document.getElementById('standbyPubKeyField').value = standby_wallet.publicKey
        document.getElementById('standbyPrivKeyField').value = standby_wallet.privateKey
        document.getElementById('standbySeedField').value = standby_wallet.seed
        document.getElementById('standbyBalanceField').value = 
          (await client.getXrpBalance(standby_wallet.address))


        document.getElementById('operationalAccountField').value = operational_wallet.address
        document.getElementById('operationalPubKeyField').value = operational_wallet.publicKey
        document.getElementById('operationalPrivKeyField').value = operational_wallet.privateKey
        document.getElementById('operationalSeedField').value = operational_wallet.seed
        document.getElementById('operationalBalanceField').value = 
          (await client.getXrpBalance(operational_wallet.address))

Disconnect from the XRP Ledger.

       client.disconnect()


      } // End of getAccountsFromSeeds()

Send XRP

// *******************************************************
// ******************** Send XRP *************************
// *******************************************************

      async function sendXRP() {

Connect to your selected ledger.

        results  = "Connecting to the selected ledger.\n"
        document.getElementById('standbyResultField').value = results
        let net = getNet()
        results = 'Connecting to ' + getNet() + '....'
        const client = new xrpl.Client(net)
        await client.connect()


        results  += "\nConnected. Sending XRP.\n"
        document.getElementById('standbyResultField').value = results


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


        results += "\nstandby_wallet.address: = " + standby_wallet.address
        document.getElementById('standbyResultField').value = results

Prepare the transaction. This is a Payment transaction from the standby wallet to the operational wallet.

The Payment transaction expects the XRP to be expressed in drops, or 1/millionth of an XRP. You can use the xrpToDrops utility to convert the send amount for you (which beats having to type an extra 6 zeroes to send 1 XRP).

        const prepared = await client.autofill({
          "TransactionType": "Payment",
          "Account": standby_wallet.address,
          "Amount": xrpl.xrpToDrops(sendAmount),
          "Destination": standbyDestinationField.value
        })

Sign the prepared transaction.

        const signed = standby_wallet.sign(prepared)

Submit the transaction and wait for the results.

        const tx = await client.submitAndWait(signed.tx_blob)

Request the balance changes caused by the transaction and report the results.

         results  += "\nBalance changes: " + 
            JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2)
         document.getElementById('standbyResultField').value = results

        document.getElementById('standbyBalanceField').value = 
          (await client.getXrpBalance(standby_wallet.address))
        document.getElementById('operationalBalanceField').value = 
          (await client.getXrpBalance(operational_wallet.address))                 
        client.disconnect()


      } // End of sendXRP()

Reciprocal Transactions

For each of the transactions, there is an accompanying reciprocal transaction, with the prefix oP, for the operational account. See the corresponding function for the standby account for code commentary.
