# 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.

|
||||
|
||||
## 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](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/)<!-- {.github-code-download} --> archive.
|
||||
|
||||
**Note:** Without the Quickstart Samples, you will not be able to try the examples that follow.
|
||||
|
||||

To get test accounts:
|
||||
|
||||
1. Open `1.get-accounts-send-xrp.html` in a browser
|
||||
2. Choose **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.
|
||||
|
||||
[](/docs/img/quickstart3.png)
|
||||
|
||||
You can transfer XRP between your new accounts. Each account has its own fields and buttons.
|
||||
|
||||

|
||||
</div>
|
||||
|
||||
To transfer XRP from the Standby account to the Operational account:
|
||||
|
||||
1. On the Standby (left) side of the form, enter the **Amount** of XRP to send.
|
||||
2. 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
|
||||
|
||||
To transfer XRP from the Operational account to the Standby account:

# Code Walkthrough
|
||||
|
||||
You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/)<!-- {.github-code-download} --> 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()
|
||||
<!-- 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

"Amount": xrpl.xrpToDrops(operationalAmountField.value),
|
||||
"Destination": operationalDestinationField.value
|
||||
})
|
||||
|
||||
// ---------------------------------------------------- Sign prepared instructions
|
||||
const signed = operational_wallet.sign(prepared)
|
||||
|
||||
// ------------------------------------------------------------ Submit signed 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()
|

```

# Create Conditional Escrows Using JavaScript
|
||||
|
||||
This example shows how to:
|
||||
|
||||
1. Create escrow payments that become available when any account enters a fulfillment code.
|
||||
|
||||
2. Complete a conditional escrow transaction.
|
||||
|
||||
3. Cancel a conditional escrow transaction.
|
||||
|
||||
[](/docs/img/conditional-escrow1.png)
|
||||
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Download and expand the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/)<!-- {.github-code-download} --> archive.
|
||||
|
||||
## Usage
|
||||
|
||||
### Create Escrow
|
||||
|
||||
You create a condition-based escrow using a fulfillment code associated with a condition code. Create the condition/fulfillment pair using the `five-bells-condition` application.
|
||||
|
||||
Install `five-bells-condition`:
|
||||
|
||||
1. In a terminal window, navigate to your local `Quickstart` directory (for convenience).
|
||||
2. Enter the command `npm install five-bells-condition`.
|
||||
|
||||
To create a condition/fulfillment pair:
|
||||
|
||||
1. In a terminal window, navigate to your `Quickstart` directory.
|
||||
2. Enter the command `node getConditionAndFulfillment.js`.
|
||||
3. Copy and save the generated Condition and Fulfillment pair.
|
||||
|
||||
[](/docs/img/conditional-escrow2.png)
|
||||
|
||||
To get test accounts:
|
||||
|
||||
1. Open `9.escrow-condition.html` in a browser
|
||||
2. Choose **Testnet** or **Devnet**.
|
||||
3. Get test accounts.
|
||||
1. If you have existing account seeds
|
||||
1. Paste 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**.
|
||||
|
||||
[](/docs/img/conditional-escrow3.png)
|
||||
|
||||
### Create Conditional Escrow:
|
||||
|
||||
<div align="center">
|
||||
<iframe width="560" height="315" src="https://www.youtube.com/embed/aUMqCFBsPW4?si=nUC4-yBOweti02be" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>
|
||||
</div>
|
||||
|
||||
When you create a conditional escrow, you need to specify the amount you want to reserve and the `Condition` value you generated above. You can also set a cancel date and time, after which the escrow is no longer available.
|
||||
|
||||
To create a conditional escrow:
|
||||
|
||||
1. Enter an **Amount** to transfer.
|
||||
2. Copy the **Operational Account** value.
|
||||
3. Paste it in the **Destination Account** field.
|
||||
4. Enter the **Escrow Condition** value.
|
||||
5. Enter the **Escrow Cancel (seconds)** value.
|
||||
6. Click **Create Escrow**.
|
||||
7. Copy and save the _Sequence Number_ of the escrow called out in the **Standby Result** field.
|
||||
|
||||
The escrow is created on the XRP Ledger instance, reserving your requested XRP amount plus the transaction cost.
|
||||
|
||||
When you create an escrow, capture and save the _Sequence Number_ so that you can use it to finish the escrow transaction.
|
||||
|
||||
[](/docs/img/conditional-escrow4.png)
|
||||
|
||||
## Finish Conditional Escrow
|
||||
|
||||
Any account can finish the conditional escrow any time before the _Escrow Cancel_ time. Following on the example above, you can use the _Sequence Number_ to finish the transaction once the Escrow Cancel time has passed.
|
||||
|
||||
To finish a time-based escrow:
|
||||
|
||||
1. Paste the sequence number in the Operational account **Escrow Sequence Number** field.
|
||||
2. Enter the `Fulfillment` code for the `Condition`.
|
||||
3. Click **Finish Conditional Escrow**.
|
||||
|
||||
The transaction completes and balances are updated for both the Standby and Operational accounts.
|
||||
|
||||
[](/docs/img/conditional-escrow5.png)
|
||||
|
||||
## Get Escrows
|
||||
|
||||
Click **Get Escrows** for either the Standby account or the Operational account to see their current list of escrows.
|
||||
|
||||
## Cancel Escrow
|
||||
|
||||
When the Escrow Cancel time passes, the escrow is no longer available to the recipient. The initiator of the escrow can reclaim the XRP, less the transaction fees. Any account can cancel an escrow once the cancel time has elapsed. Accounts that try to cancel the transaction prior to the **Escrow Cancel** time are charged the nominal transaction cost (12 drops), but the actual escrow cannot be cancelled until after the Escrow Cancel time.
|
||||
|
||||
## Oh No! I Forgot to Save the Sequence Number!
|
||||
|
||||
If you forget to save the sequence number, you can find it in the escrow transaction record.
|
||||
|
||||
1. Create a new escrow as described in [Create Escrow](#create-escrow), above.
|
||||
2. Click **Get Escrows** to get the escrow information.
|
||||
3. Copy the _PreviousTxnID_ value from the results.
|
||||

|
||||
4. Paste the _PreviousTxnID_ in the **Transaction to Look Up** field.
|
||||

|
||||
5. Click **Get Transaction**.
|
||||
6. Locate the _Sequence_ value in the results.
|
||||

# Code Walkthrough
|
||||
|
||||
You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/)<!-- {.github-code-download} --> in the source repository for this website.
|
||||
|
||||
## getConditionAndFulfillment.js
|
||||
|
||||
To generate a condition/fulfillment pair, use Node.js to run the `getConditionAndFulfillment.js` script.
|
||||
|
||||
```javascript
|
||||
function getConditionAndFulfillment() {
|
||||
```
|
||||
|
||||
Instantiate the `five-bells-condition` and `crypto` libraries.
|
||||
|
||||
```javascript
|
||||
const cc = require('five-bells-condition')
|
||||
const crypto = require('crypto')
|
||||
```
|
||||
|
||||
Create a random 32-byte seed string.
|
||||
|
||||
```javascript
|
||||
const preimageData = crypto.randomBytes(32)
|
||||
```
|
||||
|
||||
Create a fulfillment object.
|
||||
|
||||
```javascript
|
||||
const fulfillment = new cc.PreimageSha256()
|
||||
```
|
||||
|
||||
Generate a fulfillment code.
|
||||
|
||||
```javascript
|
||||
fulfillment.setPreimage(preimageData)
|
||||
```
|
||||
|
||||
Generate the condition value based on the fulfillment value.
|
||||
|
||||
```javascript
|
||||
const condition = fulfillment.getConditionBinary().toString('hex').toUpperCase()
|
||||
```
|
||||
|
||||
Return the condition.
|
||||
|
||||
```javascript
|
||||
console.log('Condition:', condition)
|
||||
```
|
||||
|
||||
Convert the fulfillment code to a hexadecimal string.
|
||||
|
||||
```javascript
|
||||
const fulfillment_hex = fulfillment.serializeBinary().toString('hex').toUpperCase()
|
||||
```
|
||||
|
||||
Return the fulfillment code. Keep it secret until you want to finish the escrow.
|
||||
|
||||
```javascript
|
||||
console.log('Fulfillment:', fulfillment_hex)
|
||||
}
|
||||
getConditionAndFulfillment()
|
||||
```

||||
```javascript
|
||||
async function createConditionalEscrow() {
|
||||
```
|
||||
|
||||
Connect to your preferred ledger.
|
||||
|
||||
```javascript
|
||||
results = "Connecting to the selected ledger.\n"
|
||||
standbyResultField.value = results
|
||||
let net = getNet()
|
||||
results = "Connecting to " + net + "....\n"
|
||||
const client = new xrpl.Client(net)
|
||||
await client.connect()
|
||||
|
||||
results += "Connected. Creating conditional escrow.\n"
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Instantiate the standby and operational wallets
|
||||
|
||||
```javascript
|
||||
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
```
|
||||
|
||||
Capture the amount to send in the escrow.
|
||||
|
||||
```javascript
|
||||
const sendAmount = standbyAmountField.value
|
||||
```
|
||||
|
||||
Update the results field.
|
||||
|
||||
```javascript
|
||||
results += "\nstandby_wallet.address: = " + standby_wallet.address
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Create a date value and add your requested number of seconds.
|
||||
|
||||
```javascript
|
||||
let escrow_cancel_date = new Date()
|
||||
escrow_cancel_date = addSeconds(parseInt(standbyEscrowCancelDateField.value))
|
||||
```
|
||||
|
||||
Prepare the `EscrowCreate` transaction.
|
||||
|
||||
```javascript
|
||||
const escrowTx = await client.autofill({
|
||||
"TransactionType": "EscrowCreate",
|
||||
"Account": standby_wallet.address,
|
||||
"Amount": xrpl.xrpToDrops(sendAmount),
|
||||
"Destination": standbyDestinationField.value,
|
||||
"CancelAfter": escrow_cancel_date,
|
||||
"Condition": standbyEscrowConditionField.value
|
||||
})
|
||||
```
|
||||
|
||||
Sign the transaction.
|
||||
|
||||
```javascript
|
||||
const signed = standby_wallet.sign(escrowTx)
|
||||
```
|
||||
|
||||
Submit the transaction and wait for the results.
|
||||
|
||||
```javascript
|
||||
const tx = await client.submitAndWait(signed.tx_blob)
|
||||
```
|
||||
|
||||
Report the results and update balance fields.
|
||||
|
||||
```javascript
|
||||
results += "\nSequence Number (Save!): " + JSON.stringify(tx.result.Sequence)
|
||||
results += "\n\nBalance changes: " +
|
||||
JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2)
|
||||
standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
||||
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Disconnect from the XRPL
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
|
||||
} // End of createTimeEscrow()
|
||||
```
|
||||
|
||||
### Finish Conditional Escrow
|
||||
|
||||
Finish the escrow by submitting the condition and fulfillment codes.
|
||||
|
||||
```javascript

||||
const sendAmount = operationalAmountField.value
|
||||
|
||||
results += "\noperational_wallet.address: = " + operational_wallet.address
|
||||
operationalResultField.value = results
|
||||
```
|
||||
|

# Create Time-based Escrows Using JavaScript
|
||||
|
||||
This example shows how to:
|
||||
|
||||
|
||||
1. Create escrow payments that become available at a specified time and expire at a specified time.
|
||||
2. Finish an escrow payment.
|
||||
3. Retrieve information on escrows attached to an account.
|
||||
3. Cancel an escrow payment and return the XRP to the sending account.
|
||||
|
||||
|
||||
[](/docs/img/quickstart-escrow1.png)
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/)<!-- {.github-code-download} -->.
|
||||
|
||||
## Usage
|
||||
|
||||
To get test accounts:
|
||||
|
||||
1. Open `8.escrow.html` in a browser
|
||||
2. Choose **Testnet** or **Devnet**.
|
||||
3. Get test accounts.
|
||||
1. If you have existing account seeds
|
||||
1. Paste 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**.
|
||||
|
||||
[](/docs/img/quickstart-escrow2.png)
|
||||
|
||||
## Create Escrow
|
||||
|
||||
<div align="center">
|
||||
<iframe width="560" height="315" src="https://www.youtube.com/embed/L-mSItlK36M?si=bltVKY7AtTnG0ucL" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>
|
||||
</div>
|
||||
|
||||
You can create a time-based escrow with a minimum time to finish the escrow and a cancel time after which the funds in escrow are no longer available to the recipient. This is a test harness: while a practical scenario might express time in days or weeks, this form lets you set the finish and cancel times in seconds so that you can quickly run through a variety of scenarios. (There are 86,400 seconds in a day, if you want to play with longer term escrows.)
|
||||
|
||||
To create a time-based escrow:
|
||||
|
||||
1. Enter an **Amount** to transfer.
|
||||
2. Copy the **Operational Account** value.
|
||||
3. Paste it in the **Destination Account** field.
|
||||
4. Set the **Escrow Finish (seconds)** value. For example, enter _10_.
|
||||
5. Set the **Escrow Cancel (seconds)** value. For example, enter _120_.
|
||||
6. Click **Create Escrow**.
|
||||
7. Copy the _Sequence Number_ of the escrow called out in the **Standby Result** field.
|
||||
|
||||
The escrow is created on the XRP Ledger instance, reserving 100 XRP plus the transaction cost. When you create an escrow, capture and save the **Sequence Number** so that you can use it to finish the escrow transaction.
|
||||
|
||||
[](/docs/img/quickstart-escrow3.png)
|
||||
|
||||
## Finish Escrow
|
||||
|
||||
The recipient of the XRP held in escrow can finish the transaction any time within the time window after the Escrow Finish date and time but before the Escrow Cancel date and time. Following on the example above, you can use the _Sequence Number_ to finish the transaction once 10 seconds have passed.
|
||||
|
||||
To finish a time-based escrow:
|
||||
|
||||
1. Paste the sequence number in the Operational account **Escrow Sequence Number** field.
|
||||
2. Click **Finish Escrow**.
|
||||
|
||||
The transaction completes and balances are updated for both the Standby and Operational accounts.
|
||||
|
||||
[](/docs/img/quickstart-escrow4.png)
|
||||
|
||||
## Get Escrows
|
||||
|
||||
Click **Get Escrows** for either the Standby account or the Operational account to see their current list of escrows. If you click the buttons now, there are no escrows at the moment.
|
||||
|
||||
For the purposes of this tutorial, follow the steps in [Create Escrow](#create-escrow), above, to create a new escrow transaction, perhaps setting **Escrow Cancel (seconds)** field to _600_ seconds to give you extra time to explore. Remember to capture the _Sequence Number_ from the transaction results.
|
||||
|
||||
Click **Get Escrows** for both the Standby and the Operational account. The `account_info` request returns the same `account_object` for both accounts, demonstrating the link between the accounts created by the escrow transaction.
|
||||
|
||||
[](/docs/img/quickstart-escrow5.png)
|
||||
|
||||
|
||||
## Cancel Escrow
|
||||
|
||||
When the Escrow Cancel time passes, the escrow is no longer available to the recipient. The initiator of the escrow can reclaim the XRP, less the transaction fees. If you try to cancel the transaction prior to the **Escrow Cancel** time, you are charged for the transaction, but the actual escrow cannot be cancelled until the time limit is reached.
|
||||
|
||||
You can wait the allotted time for the escrow you created in the previous step, then use it to try out the **Cancel Escrow** button
|
||||
|
||||
To cancel an expired escrow:
|
||||
|
||||
1. Enter the sequence number in the Standby **Escrow Sequence Number** field.
|
||||
2. Click **Cancel Escrow**.
|
||||
|
||||
The funds are returned to the Standby account, less the initial transaction fee.
|
||||
|
||||
[](/docs/img/quickstart-escrow6.png)
|
||||
|
||||
## Oh No! I Forgot to Save the Sequence Number!
|
||||
|
||||
If you forget to save the sequence number, you can find it in the escrow transaction record.
|
||||
|
||||
1. Create a new escrow as described in [Create Escrow](#create-escrow), above.
|
||||
2. Click **Get Escrows** to get the escrow information.
|
||||
3. Copy the _PreviousTxnID_ value from the results.
|
||||

|
||||
4. Paste the _PreviousTxnID_ in the **Transaction to Look Up** field.
|
||||

|
||||
5. Click **Get Transaction**.
|
||||
6. Locate the _Sequence_ value in the results.
|
||||

# Code Walkthrough
|
||||
|
||||
You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/)<!-- {.github-code-download} --> in the source repository for this website.
|
||||
|
||||
## ripple8-escrow.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.
|
||||
|
||||
### Add Seconds to Date
|
||||
|
||||
This function accomplishes two things. It creates a new date object and adds the number of seconds taken from a form field. Then, it adjusts the date from the JavaScript format to the XRP Ledger format.
|
||||
|
||||
You provide the _numOfSeconds_ argument, the second parameter is a new Date object.
|
||||
```javascript
|
||||
function addSeconds(numOfSeconds, date = new Date()) {
|
||||
```
|
||||
|
||||
Set the _seconds_ value to the date seconds plus the number of seconds you provide.
|
||||
|
||||
```javascript
|
||||
date.setSeconds(date.getSeconds() + numOfSeconds);
|
||||
```
|
||||
|
||||
JavaScript dates are in milliseconds. Divide the date by 1000 to base it on seconds.
|
||||
|
||||
```javascript
|
||||
date = Math.floor(date / 1000)
|
||||
```
|
||||
|
||||
Subtract the number of seconds in the Ripple epoch to convert the value to an XRP Ledger compatible date value.
|
||||
|
||||
```javascript
|
||||
date = date - 946684800
|
||||
```
|
||||
|
||||
Return the result.
|
||||
|
||||
```javascript
|
||||
return date;
|
||||
}
|
||||
```
|
||||
|
||||
### Create Time-based Escrow
|
||||
|
||||
```javascript
|
||||
async function createTimeEscrow() {
|
||||
```
|
||||
|
||||
Instantiate two new date objects, then set the dates to the current date plus the set number of seconds for the finish and cancel dates.
|
||||
|
||||
```javascript
|
||||
let escrow_finish_date = new Date()
|
||||
let escrow_cancel_date = new Date()
|
||||
escrow_finish_date = addSeconds(parseInt(standbyEscrowFinishDateField.value))
|
||||
escrow_cancel_date = addSeconds(parseInt(standbyEscrowCancelDateField.value))
|
||||
```
|
||||
|
||||
Connect to the ledger.
|
||||
|
||||
```javascript
|
||||
results = "Connecting to the selected ledger.\n"
|
||||
standbyResultField.value = results
|
||||
let net = getNet()
|
||||
results = "Connecting to " + net + "....\n"
|
||||
const client = new xrpl.Client(net)
|
||||
await client.connect()
|
||||
results += "Connected. Creating time-based escrow.\n"
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Get the wallet information based on the account seed values.
|
||||
|
||||
```javascript
|
||||
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
|
||||
```
|
||||
|
||||
Define the `EscrowCreate` transaction, automatically filling values in common fields.
|
||||
|
||||
```javascript
|
||||
const escrowTx = await client.autofill({
|
||||
"TransactionType": "EscrowCreate",
|
||||
"Account": standby_wallet.address,
|
||||
"Amount": xrpl.xrpToDrops(sendAmount),
|
||||
"Destination": standbyDestinationField.value,
|
||||
"FinishAfter": escrow_finish_date,
|
||||
"CancelAfter": escrow_cancel_date
|
||||
})
|
||||
```
|
||||
|
||||
Sign the escrow transaction definition.
|
||||
|
||||
```javascript
|
||||
const signed = standby_wallet.sign(escrowTx)
|
||||
```
|
||||
|
||||
Submit the transaction.
|
||||
|
||||
```javascript
|
||||
const tx = await client.submitAndWait(signed.tx_blob)
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
results += "\nSequence Number (Save!): " + JSON.stringify(tx.result.Sequence)
|
||||
results += "\n\nBalance changes: " +
|
||||
JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2)
|
||||
standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
||||
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger.
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
} // End of createTimeEscrow()
|
||||
```
|
||||
|
||||
### Finish Time-based Escrow
|
||||
|
||||
```javascript
|
||||
async function finishEscrow() {
|
||||
```
|
||||
|
||||
Connect to the XRP Ledger and get the account wallets.
|
||||
|
||||
```javascript
|
||||
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. Finishing escrow.\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
|
||||
```
|
||||
|
||||
Define the transaction. The _Owner_ is the account that created the escrow. The _OfferSequence_ is the sequence number of the escrow transaction. Automatically fill in the common fields for the transaction.
|
||||
|
||||
```javascript
|
||||
const prepared = await client.autofill({
|
||||
"TransactionType": "EscrowFinish",
|
||||
"Account": operationalAccountField.value,
|
||||
"Owner": standbyAccountField.value,
|
||||
"OfferSequence": parseInt(operationalEscrowSequenceField.value)
|
||||
})
|
||||
```
|
||||
|
||||
Sign the transaction definition.
|
||||
|
||||
```javascript
|
||||
const signed = operational_wallet.sign(prepared)
|
||||
```
|
||||
|
||||
Submit the signed transaction to the XRP ledger.
|
||||
|
||||
```javascript
|
||||
|
||||
const tx = await client.submitAndWait(signed.tx_blob)
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
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))
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger.
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
} // End of finishEscrow()
|
||||
```
|
||||
|
||||
### Get Standby Escrows
|
||||
|
||||
Get the escrows associated with the Standby account.
|
||||
|
||||
```javascript
|
||||
async function getStandbyEscrows() {
|
||||
```
|
||||
|
||||
Connect to the network. The information you are looking for is public information, so there is no need to instantiate your wallet.
|
||||
|
||||
```javascript
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
standbyResultField.value = results
|
||||
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
|
||||
results= "\nGetting standby account escrows...\n"
|
||||
```
|
||||
|
||||
Create the `account_objects` request. Specify that you want objects of the type _escrow_.
|
||||
|
||||
```javascript
|
||||
const escrow_objects = await client.request({
|
||||
"id": 5,
|
||||
"command": "account_objects",
|
||||
"account": standbyAccountField.value,
|
||||
"ledger_index": "validated",
|
||||
"type": "escrow"
|
||||
})
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
results += JSON.stringify(escrow_objects.result, null, 2)
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
} // End of getStandbyEscrows()
|
||||
```
|
||||
|
||||
### Get Operational Escrows
|
||||
|
||||
This function is the same as `getStandbyEscrows()`, but for the Operational account.
|
||||
|
||||
```javascript
|
||||
async function getOperationalEscrows() {
|
||||
```
|
||||
|
||||
Connect to the network. The information you are looking for is public information, so there is no need to instantiate your wallet.
|
||||
|
||||
```javascript
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
operationalResultField.value = results
|
||||
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
operationalResultField.value = results
|
||||
|
||||
results= "\nGetting operational account escrows...\n"
|
||||
```
|
||||
|
||||
Create the `account_objects` request. Specify that you want objects of the type _escrow_.
|
||||
|
||||
```javascript
|
||||
const escrow_objects = await client.request({
|
||||
"id": 5,
|
||||
"command": "account_objects",
|
||||
"account": operationalAccountField.value,
|
||||
"ledger_index": "validated",
|
||||
"type": "escrow"
|
||||
})
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
results += JSON.stringify(escrow_objects.result, null, 2)
|
||||
operationalResultField.value = results
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger instance.
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
} // End of getOperationalEscrows()
|
||||
```
|
||||
|
||||
### Get Transaction Info
|
||||
|
||||
```javascript
|
||||
async function getTransaction() {
|
||||
```
|
||||
|
||||
Connect to the XRP Ledger.
|
||||
|
||||
```javascript
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
operationalResultField.value = results
|
||||
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
operationalResultField.value = results
|
||||
|
||||
results= "\nGetting transaction information...\n"
|
||||
```
|
||||
|
||||
Prepare and send the transaction information request. The only required parameter is the transaction ID.
|
||||
|
||||
```javascript
|
||||
const tx_info = await client.request({
|
||||
"id": 1,
|
||||
"command": "tx",
|
||||
"transaction": operationalTransactionField.value,
|
||||
})
|
||||
```
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
results += JSON.stringify(tx_info.result, null, 2)
|
||||
operationalResultField.value = results
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger instance.
|

||||
|
||||
Connect to the XRP Ledger instance.
|
||||
|
||||
```javascript
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
standbyResultField.value = results
|
||||
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Get the account wallets.
|
||||
|
||||
```javascript
|
||||
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
```
|
||||
|
||||
Prepare the EscrowCancel transaction.
|
||||
|
||||
```javascript
|
||||
const prepared = await client.autofill({
|
||||
"TransactionType": "EscrowCancel",
|
||||
"Account": standby_wallet.address,
|
||||
"Owner": standbyAccountField.value,
|

### Configure Account
|
||||
|
||||
When transferring fiat currency, the actual transfer of funds is not simultaneous, as it is with XRP. If currency is transferred to a third party for a different currency, there can be a devaluation of the currency that impacts the originating account. To avoid this situation, this up and down valuation of currency, known as _rippling_, is not allowed by default. Currency transferred from one account can only be transferred back to the same account. To enable currency transfer to third parties, you need to set the `rippleDefault` value to true. The Token Test Harness provides a checkbox to enable or disable rippling.
|
||||
|
||||
```javascript
|
||||
// *******************************************************
|
||||
// **************** Configure Account ********************
|
||||
// *******************************************************
|
||||
|
||||
async function configureAccount(type, defaultRippleSetting) {
|
||||
```
|
||||
|
||||
Connect to the ledger
|
||||
|
||||
```javascript
|
||||
let net = getNet()
|
||||
let resultField = 'standbyResultField'
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
await client.connect()
|
||||
results += '\nConnected, finding wallet.'
|
||||
```
|
||||
|
||||
Get the account wallets.
|
||||
|
||||
```
|
||||
if (type=='standby') {
|
||||
my_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
} else {
|
||||
my_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
resultField = 'operationalResultField'
|
||||
}
|
||||
results += '\nRipple Default Setting: ' + defaultRippleSetting
|
||||
resultField.value = results
|
||||
```
|
||||
|
||||
Prepare the transaction. If the `rippleDefault` argument is true, set the `asfDefaultRipple` flag. If it is false, clear the `asfDefaultRipple` flag.
|
||||
|
||||
```javascript
|
||||
let settings_tx = {}
|
||||
if (defaultRippleSetting) {
|
||||
settings_tx = {
|
||||
"TransactionType": "AccountSet",
|
||||
"Account": my_wallet.address,
|
||||
"SetFlag": xrpl.AccountSetAsfFlags.asfDefaultRipple
|
||||
}
|
||||
results += '\n Set Default Ripple flag.'
|
||||
} else {
|
||||
settings_tx = {
|
||||
"TransactionType": "AccountSet",
|
||||
"Account": my_wallet.address,
|
||||
"ClearFlag": xrpl.AccountSetAsfFlags.asfDefaultRipple
|
||||
}
|
||||
results += '\n Clear Default Ripple flag.'
|
||||
}
|
||||
results += '\nSending account setting.'
|
||||
resultField.value = results
|
||||
```
|
||||
|
||||
Auto-fill the default values for the transaction.
|
||||
|
||||
```javascript
|
||||
const prepared = await client.autofill(settings_tx)
|
||||
```
|
||||
|
||||
Sign the transaction.
|
||||
|
||||
```javascript
|
||||
const signed = my_wallet.sign(prepared)
|
||||
```
|
||||
|
||||
Submit the transaction and wait for the result.
|
||||
|
||||
```javascript
|
||||
const result = await client.submitAndWait(signed.tx_blob)
|
||||
```
|
||||
|
||||
Report the result.
|
||||
|
||||
```javascript
|
||||
if (result.result.meta.TransactionResult == "tesSUCCESS") {
|
||||
results += '\nAccount setting succeeded.'
|
||||
document.getElementById(resultField).value = results
|
||||
} else {
|
||||
throw 'Error sending transaction: ${result}'
|
||||
results += '\nAccount setting failed.'
|
||||
resultField.value = results
|
||||
}
|
||||
client.disconnect()
|
||||
} // End of configureAccount()
|
||||
```
|
||||
|
||||
### Create Trust Line
|
||||
|
||||
A trust line enables two accounts to trade a defined currency up to a set limit. This gives the participants assurance that any exchanges are between known entities at agreed upon maximum amounts.
|
||||
|
||||
```javascript
|
||||
// *******************************************************
|
||||
// ***************** Create TrustLine ********************
|
||||
// *******************************************************
|
||||
|
||||
async function createTrustline() {
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
standbyResultField.value = results
|
||||
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Get the standby and operational wallets.
|
||||
|
||||
```javascript
|
||||
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
```
|
||||
|
||||
Capture the currency code from the standby currency field.
|
||||
|
||||
```javascript
|
||||
const currency_code = standbyCurrencyField.value
|
||||
```
|
||||
|
||||
Define the transaction, capturing the currency code and (limit) amount from the form fields.
|
||||
|
||||
```javascript
|
||||
const trustSet_tx = {
|
||||
"TransactionType": "TrustSet",
|
||||
"Account": standbyDestinationField.value,
|
||||
"LimitAmount": {
|
||||
"currency": standbyCurrencyField.value,
|
||||
"issuer": standby_wallet.address,
|
||||
"value": standbyAmountField.value
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Prepare the transaction by automatically filling the default parameters.
|
||||
|
||||
```javascript
|
||||
const ts_prepared = await client.autofill(trustSet_tx)
|
||||
```
|
||||
|
||||
|
||||
Sign the transaction.
|
||||
|
||||
|
||||
```javascript
|
||||
const ts_signed = operational_wallet.sign(ts_prepared)
|
||||
results += '\nCreating trust line from operational account to standby account...'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
|
||||
Submit the transaction and wait for the results.
|
||||
|
||||
|
||||
```javascript
|
||||
const ts_result = await client.submitAndWait(ts_signed.tx_blob)
|
||||
```
|
||||
|
||||
|
||||
Report the results.
|
||||
|
||||
|
||||
```javascript
|
||||
if (ts_result.result.meta.TransactionResult == "tesSUCCESS") {
|
||||
results += '\nTrustline established between account \n' +
|
||||
standbyDestinationField.value + ' \n and account\n' + standby_wallet.address + '.'
|
||||
standbyResultField.value = results
|
||||
} else {
|
||||
results += '\nTrustLine failed. See JavaScript console for details.'
|
||||
document.getElementById('standbyResultField').value = results
|
||||
throw 'Error sending transaction: ${ts_result.result.meta.TransactionResult}'
|
||||
}
|
||||
} //End of createTrustline()
|
||||
|
||||
```
|
||||
|
||||
### Send Issued Currency
|
||||
|
||||
Once you have created a trust line from an account to your own, you can send issued currency tokens to that account, up to the established limit.
|
||||
|
||||
```javascript
|
||||
// *******************************************************
|
||||
// *************** Send Issued Currency ******************
|
||||
// *******************************************************
|
||||
|
||||
async function sendCurrency() {
|
||||
```
|
||||
|
||||
Connect to the ledger.
|
||||
|
||||
```javascript
|
||||
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
document.getElementById('standbyResultField').value = results
|
||||
|
||||
await client.connect()
|
||||
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Get the account wallets.
|
||||
|
||||
```javascript
|
||||
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
const currency_code = standbyCurrencyField.value
|
||||
const issue_quantity = standbyAmountField.value
|
||||
|
||||
const send_token_tx = {
|
||||
"TransactionType": "Payment",
|
||||
"Account": standby_wallet.address,
|
||||
"Amount": {
|
||||
"currency": standbyCurrencyField.value,
|
||||
"value": standbyAmountField.value,
|
||||
"issuer": standby_wallet.address
|
||||
},
|
||||
"Destination": standbyDestinationField.value
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
Prepare the transaction by automatically filling default values.
|
||||
|
||||
|
||||
```javascript
|
||||
const pay_prepared = await client.autofill(send_token_tx)
|
||||
```
|
||||
|
||||
|
||||
Sign the transaction.
|
||||
|
||||
|
||||
```javascript
|
||||
const pay_signed = standby_wallet.sign(pay_prepared)
|
||||
results += 'Sending ${issue_quantity} ${currency_code} to ' +
|
||||
standbyDestinationField.value + '...'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
|
||||
Submit the transaction and wait for the results.
|
||||
|
||||
|
||||
```javascript
|
||||
const pay_result = await client.submitAndWait(pay_signed.tx_blob)
|
||||
```
|
||||
|
||||
|
||||
Report the results.
|
||||
|
||||
|
||||
```javascript
|
||||
if (pay_result.result.meta.TransactionResult == "tesSUCCESS") {
|
||||
results += 'Transaction succeeded: https://testnet.xrpl.org/transactions/${pay_signed.hash}'
|

throw 'Error sending transaction: ${pay_result.result.meta.TransactionResult}'
|
||||
}
|
||||
standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
||||
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
||||
getBalances()
|
||||
client.disconnect()
|
||||
} // end of sendCurrency()
|
||||
```
|
||||
|
||||
|
||||
|
||||
### Get Balances
|
||||
|
||||
|
||||
```javascript
|
||||
// *******************************************************
|

|
||||
```javascript
|
||||
let net = getNet()
|

await client.connect()
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|

```javascript
|
||||
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
results = "\nGetting standby account balances...\n"
|
||||
```
|
||||
|
||||
Define and send the request for the standby account, then wait for the results.
|
||||
|
||||
```javascript
|
||||
const standby_balances = await client.request({
|
||||
command: "gateway_balances",
|
||||
account: standby_wallet.address,
|
||||
ledger_index: "validated",
|
||||
hotwallet: [operational_wallet.address]
|
||||
})
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
results += JSON.stringify(standby_balances.result, null, 2)
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Define and send the request for the operational account, then wait for the results.
|
||||
|
||||
```javascript
|
||||
results += "\nGetting operational account balances...\n"
|
||||
const operational_balances = await client.request({
|
||||
command: "gateway_balances",
|
||||
account: operational_wallet.address,
|
||||
ledger_index: "validated"
|
||||
})
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
results += JSON.stringify(operational_balances.result, null, 2)
|
||||
operationalResultField.value = results
|
||||
```
|
||||
|
||||
Update the form with current XRP balances.
|
||||
|
||||
```javascript
|
||||
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
||||
standbyResultField.value = results
|
||||
standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
||||
```
|
||||
|
||||
Disconnect from the ledger.
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
} // End of getBalances()
|
||||
```
|
||||
|
||||
### 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. The `getBalances()` request does not have a reciprocal transaction, because it reports balances for both accounts.

# Send and Cash Checks
|
||||
|
||||
This example shows how to:
|
||||
|
||||
1. Send a check to transfer XRP or issued currency to another account.
|
||||
2. Get a list of checks you have sent or received.
|
||||
3. Cash a check received from another account.
|
||||
4. Cancel a check you have sent.
|
||||
|
||||
Checks offer another option for transferring funds between accounts. Checks have two particular advantages.
|
||||
|
||||
1. You can use a check to send funds to another account without first creating a trust line - the trust line is created automatically when the receiver chooses to accept the funds.
|
||||
2. The receiver can choose to accept less than the full amount of the check. This allows you to authorize a maximum amount when the actual cost is not finalized.

|
||||
## ripplex10-check.js
|
||||
|
||||
### sendCheck()
|
||||
|
||||
Connect to the XRP ledger.
|
||||
|
||||
```javascript
|
||||
async function sendCheck() {
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
standbyResultField.value = results
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Instantiate the account wallets.
|
||||
|
||||
```javascript
|
||||
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
```
|
||||
|
||||
Create the `check_amount` variable, based on the standby amount field.
|
||||
|
||||
```javascript
|
||||
var check_amount = standbyAmountField.value
|
||||
```
|
||||
|
||||
If the currency is anything but _XRP_, it's an issued currency. Update the `check_amount` variable to include the `currency` and `issuer` fields.
|
||||
|
||||
```javascript
|
||||
if (standbyCurrencyField.value != "XRP") {
|
||||
check_amount = {
|
||||
"currency": standbyCurrencyField.value,
|
||||
"value": standbyAmountField.value,
|
||||
"issuer": standby_wallet.address
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Define the `CheckCreate` transaction.
|
||||
|
||||
```javascript
|
||||
const send_check_tx = {
|
||||
"TransactionType": "CheckCreate",
|
||||
"Account": standby_wallet.address,
|
||||
"SendMax": check_amount,
|
||||
"Destination": standbyDestinationField.value
|
||||
}
|
||||
```
|
||||
|
||||
Prepare and sign the transaction.
|
||||
|
||||
```javascript
|
||||
const check_prepared = await client.autofill(send_check_tx)
|
||||
const check_signed = standby_wallet.sign(check_prepared)
|
||||
results += 'Sending ' + check_amount + ' ' + standbyCurrencyField + ' to ' +
|
||||
standbyDestinationField.value + '...'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Submit the transaction to the XRP Ledger and wait for the response.
|
||||
|
||||
```
|
||||
const check_result = await client.submitAndWait(check_signed.tx_blob)
|
||||
```
|
||||
|
||||
Report the results
|
||||
|
||||
```javascript
|
||||
if (check_result.result.meta.TransactionResult == "tesSUCCESS") {
|
||||
results += 'Transaction succeeded: https://testnet.xrpl.org/transactions/${check_signed.hash}'
|
||||
standbyResultField.value = JSON.stringify(check_result.result, null, 2)
|
||||
} else {
|
||||
results += 'Transaction failed: See JavaScript console for details.'
|
||||
standbyResultField.value = results
|
||||
throw 'Error sending transaction: ${check_result.result.meta.TransactionResult}'
|
||||
}
|
||||
```
|
||||
|
||||
Update the XRP balance fields.
|
||||
|
||||
```javascript
|
||||
standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
||||
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger.
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
} // end of sendCheck()
|
||||
```
|
||||
|
||||
### getChecks()
|
||||
|
||||
```javascript
|
||||
async function getChecks() {
|
||||
```
|
||||
|
||||
Connect to the XRP Ledger.
|
||||
|
||||
```javascript
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
standbyResultField.value = results
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
results= "\nGetting standby account checks...\n"
|
||||
```
|
||||
|
||||
Define and send the `account_objects` request, specifying `check` objects.
|
||||
|
||||
```javascript
|
||||
const check_objects = await client.request({
|
||||
"id": 5,
|
||||
"command": "account_objects",
|
||||
"account": standbyAccountField.value,
|
||||
"ledger_index": "validated",
|
||||
"type": "check"
|
||||
})
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
standbyResultField.value = JSON.stringify(check_objects.result, null, 2)
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger.
|
||||
|
||||
```javascript
|
||||
client.disconnect()
|
||||
} // End of getChecks()
|
||||
```
|
||||
### cashCheck()
|
||||
|
||||
Connect to the XRP Ledger and instantiate the account wallets.
|
||||
|
||||
```javascript
|
||||
async function cashCheck() {
|
||||
let net = getNet()
|
||||
const client = new xrpl.Client(net)
|
||||
results = 'Connecting to ' + getNet() + '....'
|
||||
standbyResultField.value = results
|
||||
await client.connect()
|
||||
results += '\nConnected.'
|
||||
standbyResultField.value = results
|
||||
|
||||
const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
```
|
||||
|
||||
Set the `check_amount` variable to the value in the **Amount** field.
|
||||
|
||||
```javascript
|
||||
var check_amount = standbyAmountField.value
|
||||
```
|
||||
|
||||
If the **Currency** is anything other than `XRP`, the check is for an issued currency. Redefine the variable to include the `currency` and `issuer` for the token.
|
||||
|
||||
```
|
||||
if (standbyCurrencyField.value != "XRP") {
|
||||
check_amount = {
|
||||
"value": standbyAmountField.value,
|
||||
"currency": standbyCurrencyField.value,
|
||||
"issuer": standbyIssuerField.value
|
||||
}
|
||||

const cash_check_tx = {
|
||||
"TransactionType": "CheckCash",
|
||||
"Account": standby_wallet.address,
|

"Amount": check_amount,
|
||||
"CheckID": standbyCheckID.value
|
||||
}
|
||||
```
|
||||
|
||||
Prepare and sign the transaction.
|
||||
|
||||
```javascript
|
||||
const cash_prepared = await client.autofill(cash_check_tx)
|
||||
const cash_signed = standby_wallet.sign(cash_prepared)
|
||||
results += ' Receiving ' + standbyAmountField.value + ' ' + standbyCurrencyField.value + '.\n'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Submit the transaction and wait for the results.
|
||||
|
||||
```javascript
|
||||
const check_result = await client.submitAndWait(cash_signed.tx_blob)
|
||||
```
|
||||
|

Report the results.
|
||||
|
||||
```javascript
|

standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
||||
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
||||
```
|
||||
|

### cancelCheck
|
||||
|
||||
Connect to the XRP Ledger and instantiate the account wallets.
|
||||
|

const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
|
||||
const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
|
||||
```
|
||||
|
||||
Define the `CheckCancel` transaction.
|
||||
|
||||
```javascript
|
||||
const cancel_check_tx = {
|
||||
"TransactionType": "CheckCancel",
|
||||
"Account": standby_wallet.address,
|
||||
"CheckID": standbyCheckID.value
|
||||
}
|
||||
```
|
||||
|
||||
Prepare and sign the transaction object.
|
||||
|
||||
```javascript
|
||||
const cancel_prepared = await client.autofill(cancel_check_tx)
|
||||
const cancel_signed = standby_wallet.sign(cancel_prepared)
|
||||
results += ' Cancelling check.\n'
|
||||
standbyResultField.value = results
|
||||
```
|
||||
|
||||
Submit the transaction and wait for the results.
|
||||
|
||||
```javascript
|
||||
const check_result = await client.submitAndWait(cancel_signed.tx_blob)
|
||||
```
|
||||
|
||||
Report the results.
|
||||
|
||||
```javascript
|
||||
if (check_result.result.meta.TransactionResult == "tesSUCCESS") {
|

}
|
||||
```
|
||||
|
||||
Update the XRP balance fields.
|
||||
|
||||
```javascript
|
||||
standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address))
|
||||
operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address))
|
||||
```
|
||||
|
||||
Disconnect from the XRP Ledger.
|
