Create Accounts and Send XRP Using JavaScript
This example shows how to:
- Create accounts on the Testnet, funded with 1000 test XRP with no actual value.
- Retrieve the accounts from seed values.
- Transfer XRP between accounts.
When you create an account, you receive a public/private key pair offline. Your account 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.
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.
Note: Without the Quickstart Samples, you will not be able to try the examples that follow.
Usage
To get test accounts:
- Open
1.get-accounts-send-xrp.html
in a browser - Choose Testnet or Devnet.
- Click Get New Standby Account.
- Click Get New Operational Account.
- 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.
You can transfer XRP between your new accounts. Each account has its own fields and buttons.
To transfer XRP from the Standby account to the Operational account:
- On the Standby (left) side of the form, enter the Amount of XRP to send.
- Copy and paste the Operational Account field to the Standby Destination field.
- Click Send XRP> to transfer XRP from the standby account to the operational account
To transfer XRP from the Operational account to the Standby account:
- On the Operational (right) side of the form, enter the Amount of XRP to send.
- Copy and paste the Standby Account field to the Operational Destination field.
- Click <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, Testnet, or Devnet. 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("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 ' + net + '....'
Use the default faucet using a null value.
let faucetHost = null
Report progress in the appropriate results field.
if (type == 'standby') { standbyResultField.value = results } else { operationalResultField.value = results }
Connect to the server.
await client.connect() results += '\nConnected, funding wallet.' if (type == 'standby') { standbyResultField.value = results } else { operationalResultField.value = results }
Create and fund a test account.
const my_wallet = (await client.fundWallet(null, { faucetHost })).wallet results += '\nGot a wallet.' if (type == 'standby') { standbyResultField.value = results } else { operationalResultField.value = results }
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') { standbyAccountField.value = my_wallet.address standbyPubKeyField.value = my_wallet.publicKey standbyPrivKeyField.value = my_wallet.privateKey standbyBalanceField.value = (await client.getXrpBalance(my_wallet.address)) standbySeedField.value = my_wallet.seed results += '\nStandby account created.' standbyResultField.value = results
Otherwise, populate the operational account fields.
} else { operationalAccountField.value = my_wallet.address operationalPubKeyField.value = my_wallet.publicKey operationalPrivKeyField.value = my_wallet.privateKey operationalSeedField.value = my_wallet.seed operationalBalanceField.value = (await client.getXrpBalance(my_wallet.address)) results += '\nOperational account created.' 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.
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() + '....' standbyResultField.value = results await client.connect() results += '\nConnected, finding wallets.\n' 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.
standbyAccountField.value = standby_wallet.address standbyPubKeyField.value = standby_wallet.publicKey standbyPrivKeyField.value = standby_wallet.privateKey standbySeedField.value = standby_wallet.seed standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address)) operationalAccountField.value = operational_wallet.address operationalPubKeyField.value = operational_wallet.publicKey operationalPrivKeyField.value = operational_wallet.privateKey operationalSeedField.value = operational_wallet.seed 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" standbyResultField.value = results let net = getNet() results = 'Connecting to ' + getNet() + '....' const client = new xrpl.Client(net) await client.connect() results += "\nConnected. Sending XRP.\n" 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 standbyResultField.value = results
Prepare the transaction. This is a Payment transaction from the standby address to the operational address.
The Payment transaction expects the XRP to be expressed in drops, or 1/millionth of an XRP. You can use the xrpToDrops()
method 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) standbyResultField.value = results standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address)) 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.
