# Send a Multi-Account Batch Transaction
|
||||
|
||||
This tutorial shows you how to create a [Batch transaction][] containing transactions from multiple accounts, where each account must sign the Batch transaction. Any account, even one not involved in the inner transactions, can submit the batch.
|
||||
|
||||
## Goals
|
||||
|
||||
By the end of this tutorial, you will be able to:
|
||||
|
||||
- Create a Batch transaction with multiple inner transactions, signed by multiple accounts, and submitted by a third party account.
|
||||
- Configure the Batch transaction to ensure atomicity, so that either all inner transactions succeed or they all fail.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
To complete this tutorial, you should:
|
||||
|
||||
- Have a basic understanding of the XRP Ledger.
|
||||
- Have an XRP Ledger client library set up in your development environment. This page provides examples for the following:
|
||||
- **JavaScript** with the [xrpl.js library](https://github.com/XRPLF/xrpl.js). See [Get Started Using JavaScript](../../javascript/build-apps/get-started.md) for setup steps.
|
||||
|
||||
## Source Code
|
||||
|
||||
You can find the complete source code for this tutorial's examples in the [code samples section of this website's repository](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/batch/).
|
||||
|
||||
## Steps
|
||||
|
||||
The example in this tutorial demonstrates a scenario where Bob and Charlie both owe Alice 50 XRP each, and a third-party (such as a payment processor) submits the Batch transaction atomically to ensure Alice is paid by both parties.
|
||||
|
||||
### 1. Install dependencies
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
From the code sample folder, use npm to install dependencies:
|
||||
|
||||
```bash
|
||||
npm install xrpl
|
||||
```
|
||||
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
### 2. Set up client and accounts
|
||||
|
||||
To get started, import the client library and instantiate a client to connect to the XRPL. Then, create the accounts for Alice, Bob, Charlie, and the third-party.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/multiAccountBatch.js" language="js" from="import xrpl" before="// Create inner transactions" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
### 3. Prepare inner transactions
|
||||
|
||||
Next, prepare the inner transactions that will be included in the batch.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/multiAccountBatch.js" language="js" from="// Create inner transactions" to="// Send Batch transaction" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
The first transaction sends a payment of 50 XRP from Charlie to Alice, and the second sends a payment of 50 XRP from Bob to Alice. Both transactions must include the `tfInnerBatchTxn` (0x40000000) flag to indicate that they are inner transactions of a batch.
|
||||
|
||||
Inner transactions must have a Fee of **0** and an empty string for the `SigningPubKey`. The outer Batch transaction handles the overall fee and signing for all inner transactions.
|
||||
|
||||
{% admonition type="info" name="Note" %}
|
||||
The `Fee` and `SigningPubKey` fields are omitted as the client library's _autofill_ functionality automatically populates these when submitting the Batch transaction.
|
||||
|
||||
You typically don't need to set these manually, but if you do, ensure `Fee` is set to 0 and `SigningPubKey` is an empty string.
|
||||
{% /admonition %}
|
||||
|
||||
### 4. Prepare Batch transaction
|
||||
|
||||
Create the Batch transaction and provide the inner transactions. The key fields to note are:
|
||||
|
||||
| Field | Value |
|
||||
|:---------------- |:---------- |
|
||||
| TransactionType | The type of transaction, in this case `Batch`.|
|
||||
| Account | The wallet address of the account that is sending the Batch transaction. |
|
||||
| Flags | The flags for the Batch transaction. For this example the transaction is configured with the `tfAllOrNothing` (0x00010000) flag to ensure that either all inner transactions succeed or they all fail atomically. See [Batch Flags](../../../references/protocol/transactions/types/batch.md#batch-flags) for other options. |
|
||||
| RawTransactions | Contains the list of inner transactions to be applied. There can be up to **8** transactions included. These transactions can come from one account or multiple accounts. |
|
||||
| BatchSigners | The list of signatures required for the Batch transaction. This is required because there are multiple accounts' transactions included in the batch. |
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/multiAccountBatch.js" language="js" from="// Send Batch transaction" before="// Gather batch signatures" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
Because we used `autofill`, the client library automatically fills in any missing fields, like `Fee` and `SigningPubKey`. Additionally, we specify the expected number of signers (2 in this case).
|
||||
|
||||
### 5. Gather batch signatures
|
||||
|
||||
To add the `BatchSigners` field, you need to collect signatures from each account that's sending a transaction within the batch. In this case we need two signatures, one from Charlie and one from Bob. Each sender must sign the Batch transaction to authorize their payment.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
The **xrpl.js** library provides a helper function, `signMultiBatch()`, to sign the Batch transaction for each account.
|
||||
|
||||
Then, to combine the signatures into a single signed Batch transaction, use the `combineBatchSigners()` utility function.
|
||||
{% code-snippet file="/_code-samples/batch/js/multiAccountBatch.js" language="js" from="// Gather batch signatures" to="// Submit" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
### 6. Submit Batch transaction
|
||||
|
||||
With all the required signatures gathered, the third-party wallet can now submit the Batch transaction.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/multiAccountBatch.js" language="js" from="// Submit" before="// Check Batch transaction" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
### 6. Check Batch transaction result
|
||||
|
||||
To check the result of the Batch transaction submission:
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/multiAccountBatch.js" language="js" from="// Check Batch transaction" before="// Verify balances after transaction" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
The code checks for a `tesSUCCESS` result and displays the response details.
|
||||
|
||||
{% admonition type="warning" name="Warning" %}
|
||||
A `tesSUCCESS` result indicates that the Batch transaction was processed successfully, but does not guarantee the inner transactions succeeded. For example, see the [following transaction on the XRPL Explorer](https://devnet.xrpl.org/transactions/20CFCE5CF75E93E6D1E9C1E42F8E8C8C4CB1786A65BE23D2EA77EAAB65A455C5/simple).
|
||||
{% /admonition %}
|
||||
|
||||
To verify that the inner transactions have been successful, check the account balances to confirm the expected changes.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/multiAccountBatch.js" language="js" from="// Verify balances after transaction" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
Because the Batch transaction is configured with a `tfAllOrNothing` flag, if any inner transaction fails, **all** inner transactions wil fail, and only the Batch transaction fee is deducted from the **third-party wallet**.

# Send a Single Account Batch Transaction
|
||||
|
||||
A [Batch transaction][] allows you to group multiple transactions together and execute them as a single atomic operation.
|
||||
|
||||
This tutorial shows you how to create a Batch transaction where a single account submits multiple transactions that either all succeed together or all fail together.
|
||||
|
||||
## Goals
|
||||
|
||||
By the end of this tutorial, you will be able to:
|
||||
|
||||
- Create a Batch transaction with multiple inner transactions, signed and submitted by a single account.
|
||||
- Configure the Batch transaction to ensure atomicity, so that either all inner transactions succeed or they all fail.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
To complete this tutorial, you should:
|
||||
|
||||
- Have a basic understanding of the XRP Ledger.
|
||||
- Have an XRP Ledger client library set up in your development environment. This page provides examples for the following:
|
||||
- **JavaScript** with the [xrpl.js library](https://github.com/XRPLF/xrpl.js). See [Get Started Using JavaScript](../../javascript/build-apps/get-started.md) for setup steps.

||||
|
||||
You can find the complete source code for this tutorial's examples in the [code samples section of this website's repository](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/batch/).
|
||||
|
||||
## Steps
|
||||
|
||||
The example in this tutorial demonstrates a scenario where an account sends multiple payments that must be processed atomically in one Batch transaction.
|
||||
|
||||
### 1. Install dependencies
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
From the code sample folder, use npm to install dependencies:
|
||||
|
||||
```bash
|
||||
npm install xrpl
|
||||
```
|
||||
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
### 2. Set up client and accounts
|
||||
|
||||
To get started, import the client library and instantiate a client to connect to the XRPL. For this tutorial you need a funded account for the Batch transaction **sender**, and two other accounts to **receive** the payments.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/singleAccountBatch.js" language="js" from="import xrpl" before="// Create inner transactions" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
### 3. Prepare inner transactions
|
||||
|
||||
Next, prepare the inner transactions that will be included in the batch.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/singleAccountBatch.js" language="js" from="// Create inner transactions" to="// Send Batch transaction" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
The first transaction sends a payment of 2 XRP from the sender to `wallet1`, and the second transaction sends 5 XRP from the sender to `wallet2`. Both transactions must include the `tfInnerBatchTxn` (0x40000000) flag to indicate that they are inner transactions of a batch.
|
||||
|
||||
Inner transactions must have a Fee of **0** and an empty string for the `SigningPubKey`. The outer Batch transaction handles the overall fee and signing for all inner transactions.
|
||||
|
||||
{% admonition type="info" name="Note" %}
|
||||
The `Fee` and `SigningPubKey` fields are omitted as the client library's _autofill_ functionality automatically populates these when submitting the Batch transaction.
|
||||
|
||||
You typically don't need to set these manually, but if you do, ensure `Fee` is set to 0 and `SigningPubKey` is an empty string.
|
||||
{% /admonition %}
|
||||
|
||||
### 4. Prepare Batch transaction
|
||||
|
||||
Create the Batch transaction and provide the inner transactions. The key fields to note are:
|
||||
|
||||
| Field | Value |
|
||||
|:---------------- |:---------- |
|
||||
| TransactionType | The type of transaction, in this case `Batch`.|
|
||||
| Account | The wallet address of the account that is sending the Batch transaction. |
|
||||
| Flags | The flags for the Batch transaction. For this example the transaction is configured with the `tfAllOrNothing` (0x00010000) flag to ensure that either all inner transactions succeed or they all fail atomically. See [Batch Flags](../../../references/protocol/transactions/types/batch.md#batch-flags) for other options. |
|
||||
| RawTransactions | Contains the list of inner transactions to be applied. There can be up to **8** transactions included. These transactions can come from one account or multiple accounts. |
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/singleAccountBatch.js" language="js" from="// Send Batch transaction" before="// Submit" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
### 5. Submit Batch transaction
|
||||
|
||||
Now the sender can submit the Batch transaction:
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/singleAccountBatch.js" language="js" from="// Submit" before="// Check Batch transaction" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
Because `autofill` is set to `true`, the client library automatically fills in any missing fields, like the `Fee` and `SigningPubKey`, before submitting the batch.
|
||||
|
||||
### 6. Check Batch transaction result
|
||||
|
||||
To check the result of the Batch transaction submission:
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Javascript" %}
|
||||
{% code-snippet file="/_code-samples/batch/js/singleAccountBatch.js" language="js" from="// Check Batch transaction" before="// Verify balances after transaction" /%}
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
The code checks for a `tesSUCCESS` result and displays the response details.
|
||||
|
||||
{% admonition type="warning" name="Warning" %}
|
||||
A `tesSUCCESS` result indicates that the Batch transaction was processed successfully, but does not guarantee the inner transactions succeeded.
|
||||
|
||||
For example, see the [following transaction on the XRPL Explorer](https://devnet.xrpl.org/transactions/20CFCE5CF75E93E6D1E9C1E42F8E8C8C4CB1786A65BE23D2EA77EAAB65A455C5/simple).
|
||||
{% /admonition %}
|
