# Create Accounts and Send XRP Using JavaScript
|
|
|
|
This example shows how to:
|
|
|
|
1. Create accounts on the Testnet, funded with 1000 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. 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.

|
|
|
|
```
|
|
npm install xrpl
|
|
```
|
|
|
|

## 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()
|
|
<!-- SPELLING_IGNORE: getnet -->
|
|
|
|
```javascript
|
|
// ******************************************************
|
|
// ************* Get the Preferred Network **************
|
|
// ******************************************************
|
|
|
|
function getNet() {
|
|
```
|
|
|
|
This function uses brute force `if` statements to discover the selected network instance and return the URI.
|
|
|
|
```javascript
|
|
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)
|
|
<!-- SPELLING_IGNORE: getaccount -->
|
|
|
|
```javascript
|
|
// *******************************************************
|
|
// ************* Get Account *****************************
|
|
// *******************************************************
|
|
|
|
async function getAccount(type) {
|
|
```
|
|
|
|
Get the selected ledger.
|
|
|
|
```javascript
|
|
let net = getNet()
|
|
```
|
|
|
|
Instantiate a client.
|
|
|
|
```javascript
|
|
const client = new xrpl.Client(net)
|
|
```
|
|
|
|
Use the _results_ variable to capture progress information.
|
|
|
|
```javascript
|
|
results = 'Connecting to ' + net + '....'
|
|
```
|
|
Use the default faucet using a _null_ value.
|
|
|
|
```javascript
|
|
let faucetHost = null
|
|
```
|
|
|
|
Report progress in the appropriate results field.
|
|
|
|
```javascript
|
|
if (type == 'standby') {
|
|
standbyResultField.value = results
|
|
} else {
|
|
operationalResultField.value = results
|
|
}
|
|
```
|
|
|
|
Connect to the server.
|
|
|
|
```javascript
|
|
await client.connect()
|
|
|
|
results += '\nConnected, funding wallet.'
|
|
if (type == 'standby') {
|
|
standbyResultField.value = results
|
|
} else {
|
|
operationalResultField.value = results
|
|
}
|
|
|
|
```
|
|
|
|
Create and fund a test account.
|
|
|
|
```javascript
|
|
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.
|
|
|
|
```javascript
|
|
const my_balance = (await client.getXrpBalance(my_wallet.address))
|
|
```
|
|
|
|
If this is a standby account, populate the standby account fields.
|
|
|
|
```javascript
|
|
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.
|
|
|
|
```javascript
|
|
} 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.
|
|
|
|
```javascript
|
|
seeds.value = standbySeedField.value + '\n' + operationalSeedField.value
|
|
```
|
|
|
|
Disconnect from the XRP ledger.
|
|
|
|
```javascript
|
|
client.disconnect()
|
|
} // End of getAccount()
|
|
```
|
|
|
|
### Get Accounts from Seeds
|
|
|
|
```javascript
|
|
// *******************************************************
|
|
// ********** Get Accounts from Seeds ********************
|
|
// *******************************************************
|
|
|
|
async function getAccountsFromSeeds() {
|
|
```
|
|
|
|
Connect to the selected network.
|
|
|
|
```javascript
|
|
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.
|
|
|
|
```javascript
|
|
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.
|
|
|
|
```javascript
|
|
const standby_wallet = xrpl.Wallet.fromSeed(lines[0])
|
|
const operational_wallet = xrpl.Wallet.fromSeed(lines[1])
|
|
```
|
|
|
|
Get the current XRP balances for the accounts.
|
|
|
|
```javascript
|
|
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.
|
|
|
|
```javascript
|
|
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.
|
|
|
|
```javascript
|
|
client.disconnect()
|
|
} // End of getAccountsFromSeeds()
|
|
```
|
|
|
|
### Send XRP
|
|
|
|
```javascript
|
|
// *******************************************************
|
|
// ******************** Send XRP *************************
|
|
// *******************************************************
|
|
|
|
async function sendXRP() {
|
|
```
|
|
|
|
Connect to your selected ledger.
|
|
|
|
```javascript
|
|
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).
|
|
|
|
```javascript
|
|
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.
|
|
|
|
```javascript
|
|
// **********************************************************************
|
|
// ****** Reciprocal Transactions ***************************************
|
|
// **********************************************************************
|
|
|
|
// *******************************************************
|
|
// ********* Send XRP from Operational account ***********
|
|
// *******************************************************
|
|
|
|
async function oPsendXRP() {
|
|
|
|
results = "Connecting to the selected ledger.\n"
|
|
operationalResultField.value = results
|
|
let net = getNet()
|
|
results = 'Connecting to ' + getNet() + '....'
|
|
const client = new xrpl.Client(net)
|
|
await client.connect()
|
|
|
|
results += "\nConnected. Sending XRP.\n"
|
|
operationalResultField.value = results
|
|
|
|
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
|
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
|
const sendAmount = operationalAmountField.value
|
|
|
|
results += "\noperational_wallet.address: = " + operational_wallet.address
|
|
operationalResultField.value = results
|
|
|
|
// ---------------------------------------------------------- Prepare transaction
|
|
const prepared = await client.autofill({
|
|
"TransactionType": "Payment",
|
|
"Account": operational_wallet.address,
|
|
"Amount": xrpl.xrpToDrops(operationalAmountField.value),
|
|
"Destination": operationalDestinationField.value
|
|
})
|
|
|
|
// ---------------------------------------------------- Sign prepared instructions
|
|
const signed = operational_wallet.sign(prepared)
|
|
|
|
// ------------------------------------------------------------ Submit signed blob
|
|
const tx = await client.submitAndWait(signed.tx_blob)
|
|
|
|
results += "\nBalance changes: " +
|
|
JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2)
|
|
operationalResultField.value = results
|
|
standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
|
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
|
|
|
client.disconnect()
|
|
} // End of oPsendXRP()
|
|
```
