# Get Started Using Python Library
|
||||||
|
|
||||||
|
Connects to the XRP Ledger and gets account information using Python.
|
||||||
|
|
||||||
|
To download the source code, see [Get Started Using Python Library](http://xrpl.org/docs/tutorials/python/build-apps/get-started).
|
||||||
|
|
||||||
|
## Run the Code
|
||||||
|
|
||||||
|
Quick setup and usage:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
python -m venv .venv
|
||||||
|
source .venv/bin/activate
|
||||||
|
pip install -r requirements.txt
|
||||||
|
python ./get-acct-info.py
|
||||||
|
```
|
||||||
|
|
||||||
|
You should see output similar to the following:

# Issue a Multi-Purpose Token (MPT)
|
||||||
|
|
||||||
|
A [Multi-Purpose Token (MPT)](../../../concepts/tokens/fungible-tokens/multi-purpose-tokens.md) lets you to quickly access powerful, built-in tokenization features on the XRP Ledger with minimal code.
|
||||||
|
|
||||||
|
This tutorial shows you how to issue an MPT with on-chain metadata such as the token's ticker, name, or description, encoded according to the MPT [metadata schema](../../../concepts/tokens/fungible-tokens/multi-purpose-tokens.md#metadata-schema) defined in [XLS-89](https://xls.xrpl.org/xls/XLS-0089-multi-purpose-token-metadata-schema.html).
|
||||||
|
|
||||||
|
## Goals
|
||||||
|
|
||||||
|
By the end of this tutorial, you will be able to:
|
||||||
|
|
||||||
|
- Issue a new MPT using the `MPTokenIssuanceCreate` transaction.
|
||||||
|
- Encode or decode token metadata following MPT standards best practices.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
To complete this tutorial, you should:
|
||||||
|
|
||||||
|
- Have a basic understanding of the XRP Ledger and token issuance.
|
||||||
|
- 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 example in the [code samples section of this website's repository](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/issue-mpt-with-metadata).
|
||||||
|
|
||||||
|
## Steps
|
||||||
|
|
||||||
|
### 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 fund issuer wallet
|
||||||
|
|
||||||
|
Import the client library, instantiate a client to connect to the XRPL, and fund a new wallet to act as the token issuer.
|
||||||
|
|
||||||
|
{% tabs %}
|
||||||
|
{% tab label="Javascript" %}
|
||||||
|
{% code-snippet file="/_code-samples/issue-mpt-with-metadata/js/issue-mpt-with-metadata.js" language="js" before="// Define metadata as JSON" /%}
|
||||||
|
{% /tab %}
|
||||||
|
{% /tabs %}
|
||||||
|
|
||||||
|
### 3. Define and encode MPT metadata
|
||||||
|
|
||||||
|
Define your token's metadata as a JSON object:
|
||||||
|
|
||||||
|
{% tabs %}
|
||||||
|
{% tab label="Javascript" %}
|
||||||
|
{% code-snippet file="/_code-samples/issue-mpt-with-metadata/js/issue-mpt-with-metadata.js" language="js" from="// Define metadata as JSON" before="// Encode the metadata" /%}
|
||||||
|
{% /tab %}
|
||||||
|
{% /tabs %}
|
||||||
|
|
||||||
|
The metadata schema supports both long field names (e.g., `ticker`, `name`, `desc`) and compact short keys (e.g., `t`, `n`, `d`). To save space on the ledger, it’s recommended to use short key names. The MPT metadata field has a 1024-byte limit, so using compact keys allows you to include more information.
|
||||||
|
|
||||||
|
The SDK libraries provide utility functions to encode or decode the metadata for you, so you don't have to. If long field names are provided in the metadata JSON, the _encoding_ utility function automatically shortens them to their compact key equivalents before encoding. Similarly, when decoding, the _decoding_ utility function converts the shorthands back to the respective long names.
|
||||||
|
|
||||||
|
{% tabs %}
|
||||||
|
{% tab label="Javascript" %}
|
||||||
|
Use the `encodeMPTokenMetadata()` function to encode metadata with `xrpl.js`.
|
||||||
|
{% code-snippet file="/_code-samples/issue-mpt-with-metadata/js/issue-mpt-with-metadata.js" language="js" from="// Encode the metadata" before="// Define the transaction" /%}
|
||||||
|
{% /tab %}
|
||||||
|
|
||||||
|
{% /tabs %}
|
||||||
|
|
||||||
|
{% admonition type="warning" name="Warning" %}
|
||||||
|
While the encoding utility formats the JSON for you correctly and replaces the full key names with shorthands, it does **not** validate the metadata content or size.
|
||||||
|
{% /admonition %}
|
||||||
|
|
||||||
|
### 4. Prepare the MPTokenIssuanceCreate transaction
|
||||||
|
|
||||||
|
Create the transaction object, specifying the issuer, asset scale, maximum amount, transfer/trade flags, and the encoded metadata.
|
||||||
|
|
||||||
|
| Field | Value |
|
||||||
|
|:------------------|:---------------------------------------------------------------------|
|
||||||
|
| `TransactionType` | The type of transaction, in this case `MPTokenIssuanceCreate`. |
|
||||||
|
| `Account` | The wallet address of the account that is issuing the MPT. |
|
||||||
|
| `AssetScale` | The number of decimal places for the token. |
|
||||||
|
| `MaximumAmount` | The maximum supply of the token to be issued. |
|
||||||
|
| `TransferFee` | The transfer fee (if any) to charge for token transfers. |
|
||||||
|
| `Flags` | Flags to control transfer/trade permissions. |
|
||||||
|
| `MPTokenMetadata` | The hex-encoded metadata for the token. |
|
||||||
|
|
||||||
|
{% tabs %}
|
||||||
|
{% tab label="Javascript" %}
|
||||||
|
{% code-snippet file="/_code-samples/issue-mpt-with-metadata/js/issue-mpt-with-metadata.js" language="js" from="// Define the transaction" before="// Prepare, sign, and submit the transaction" /%}
|
||||||
|
{% /tab %}
|
||||||
|
{% /tabs %}
|
||||||
|
|
||||||
|
### 5. Submit the transaction
|
||||||
|
|
||||||
|
Sign and submit the transaction, then wait for validation.
|
||||||
|
|
||||||
|
{% tabs %}
|
||||||
|
{% tab label="Javascript" %}
|
||||||
|
{% code-snippet file="/_code-samples/issue-mpt-with-metadata/js/issue-mpt-with-metadata.js" language="js" from="// Prepare, sign, and submit the transaction" before="// Check transaction results" /%}
|
||||||
|
{% /tab %}
|
||||||
|
{% /tabs %}
|
||||||
|
|
||||||
|
### 6. Check transaction result
|
||||||
|
|
||||||
|
Verify that the transaction succeeded and retrieve the MPT issuance ID.
|
||||||
|
|
||||||
|
{% tabs %}
|
||||||
|
{% tab label="Javascript" %}
|
||||||
|
{% code-snippet file="/_code-samples/issue-mpt-with-metadata/js/issue-mpt-with-metadata.js" language="js" from="// Check transaction results" before="// Look up MPT Issuance entry" /%}
|
||||||
|
{% /tab %}
|
||||||
|
{% /tabs %}
|
||||||
|
|
||||||
|
{% admonition type="info" name="Note" %}
|
||||||
|
A `tesSUCCESS` result indicates that the MPT issuance transaction was processed successfully and the token was created.
|
||||||
|
{% /admonition %}
|
||||||
|
|
||||||
|
### 7. Confirm MPT issuance and decode metadata
|
||||||
|
|
||||||
|
Look up the MPT issuance entry in the validated ledger and decode the metadata to verify it matches your original input.
|
||||||
|
|
||||||
|
{% tabs %}
|
||||||
|
{% tab label="Javascript" %}
|
||||||
|
{% code-snippet file="/_code-samples/issue-mpt-with-metadata/js/issue-mpt-with-metadata.js" language="js" from="// Look up MPT Issuance entry" /%}
|
||||||
|
{% /tab %}
|
||||||
|
{% /tabs %}
|
||||||
|
|
||||||
|
The _decoding_ utility function converts the metadata shorthand key names back to the respective long names.

```py
|
Follow the steps to create a simple application with `xrpl-py`.
|
||||||
pip3 install xrpl-py
|
|
||||||
|
{% step id="import-tag" %}
|
||||||
|
### 1. Install Dependencies
|
||||||
|
|
||||||
|
Start a new project by creating an empty folder, then move into that folder and set up a Python virtual environment with the necessary dependencies:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
# Create and activate a virtual environment
|
||||||
|
python -m venv .venv
|
||||||
|
source .venv/bin/activate
|
||||||
|
|
||||||
|
# Install the xrpl-py library
|
||||||
|
pip install xrpl-py
|
||||||
```
|
```
|
||||||
|
|
||||||
## Start Building
|
Alternatively, if you're using the downloaded source code, you can install all dependencies from the `requirements.txt` file:
|
||||||
|
|
||||||
When you're working with the XRP Ledger, there are a few things you'll need to manage, whether you're adding XRP to your [account](../../../concepts/accounts/index.md), integrating with the [decentralized exchange](../../../concepts/tokens/decentralized-exchange/index.md), or [issuing tokens](../../../concepts/tokens/index.md). This tutorial walks you through basic patterns common to getting started with all of these use cases and provides sample code for implementing them.
|
```sh
|
||||||
|
python -m venv .venv
|
||||||
|
source .venv/bin/activate
|
||||||
|
pip install -r requirements.txt
|
||||||
|
```
|
||||||
|
{% /step %}
|
||||||
|
|
||||||
Here are the basic steps you'll need to cover for almost any XRP Ledger project:
|
### 2. Connect to the XRP Ledger
|

#### Connect to the XRP Ledger Testnet
|
||||||
1. [Query the XRP Ledger.](#3-query-the-xrp-ledger)
|
|
||||||
|
|
||||||
|
To make queries and submit transactions, you need to connect to the XRP Ledger. To do this with `xrpl-py`, use the [`xrp.clients` module](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.clients.html).
|
||||||
|
|
||||||
### 1. Connect to the XRP Ledger
|
{% admonition type="info" name="Note" %}
|
||||||
|
The standard approach with `xrpl-py` is to use the JSON-RPC client. While a WebSocket client is available, it requires you to use `async`/`await` throughout your code. For most use cases, stick with JSON-RPC to avoid the complexity of asynchronous programming.

When you're ready to integrate with the production XRP Ledger, you'll need to connect to the Mainnet. You can do that in two ways:
|
||||||
|
|
||||||
* By [installing the core server](../../../infrastructure/installation/index.md) (`rippled`) and running a node yourself. The core server connects to the Mainnet by default, but you can [change the configuration to use Testnet or Devnet](../../../infrastructure/configuration/connect-your-rippled-to-the-xrp-test-net.md). [There are good reasons to run your own core server](../../../concepts/networks-and-servers/index.md#reasons-to-run-your-own-server). If you run your own server, you can connect to it like so:

To store value and execute transactions on the XRP Ledger, you need an account: a [set of keys](../../../concepts/accounts/cryptographic-keys.md#key-components) and an [address](../../../concepts/accounts/addresses.md) that's been [funded with enough XRP](../../../concepts/accounts/index.md#creating-accounts) to meet the [account reserve](../../../concepts/accounts/reserves.md). The address is the identifier of your account and you use the [private key](../../../concepts/accounts/cryptographic-keys.md#private-key) to sign transactions that you submit to the XRP Ledger.

For testing and development purposes, you can use the [XRP Faucets](/resources/dev-tools/xrp-faucets) to generate keys and fund the account on the Testnet or Devnet. For production purposes, you should take care to store your keys and set up a [secure signing method](../../../concepts/transactions/secure-signing.md). Another difference in production is that XRP has real worth, so you can't get it for free from a faucet.

```
|
|
||||||
|
|
||||||
#### Using the account
|
|
||||||
|
|
||||||
In this tutorial we only query details about the generated account from the XRP Ledger, but you can use the values in the `Wallet` instance to prepare, sign, and submit transactions with `xrpl-py`.
|
|
||||||
|
|
||||||
##### Prepare
|
|
||||||
|
|
||||||
To prepare the transaction:
|
|
||||||
|
|
||||||
{% code-snippet file="/_code-samples/get-started/py/prepare-payment.py" from="# Prepare payment" before="# print prepared payment" language="py" /%}
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
##### Sign and submit
|
|
||||||
|
|
||||||
To sign and submit the transaction:
|
|
||||||
|
|
||||||
{% code-snippet file="/_code-samples/get-started/py/prepare-payment.py" from="# Sign and submit the transaction" before="# Print tx response" language="py" /%}
|
|
||||||
|
|
||||||
|
|
||||||
##### Derive an X-address
|
|
||||||
|
|
||||||
You can use `xrpl-py`'s [`xrpl.core.addresscodec`](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.core.addresscodec.html) module to derive an [X-address](https://xrpaddress.info/) from the `Wallet.address` field:
|
|
||||||
|
|
||||||
{% code-snippet file="/_code-samples/get-started/py/get-acct-info.py" from="# Derive an x-address from the classic address:" before="# Look up info about your account" language="py" /%}
|
|
||||||
|
|
||||||
The X-address format [packs the address and destination tag](https://github.com/XRPLF/XRPL-Standards/issues/6) into a more user-friendly value.
|
|
||||||
|
|
||||||
|
|
||||||
### 3. Query the XRP Ledger
|
|
||||||
|
|
||||||
You can query the XRP Ledger to get information about [a specific account](../../../references/http-websocket-apis/public-api-methods/account-methods/index.md), [a specific transaction](../../../references/http-websocket-apis/public-api-methods/transaction-methods/tx.md), the state of a [current or a historical ledger](../../../references/http-websocket-apis/public-api-methods/ledger-methods/index.md), and [the XRP Ledger's decentralized exchange](../../../references/http-websocket-apis/public-api-methods/path-and-order-book-methods/index.md). You need to make these queries, among other reasons, to look up account info to follow best practices for [reliable transaction submission](../../../concepts/transactions/reliable-transaction-submission.md).

You need to make these queries, among other reasons, to look up account info to follow best practices for [reliable transaction submission](../../../concepts/transactions/reliable-transaction-submission.md).
|
||||||
|
|
||||||
Here, we use `xrpl-py`'s [`xrpl.account`](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.account.html) module to look up information about the [account we got](#2-get-account) in the previous step.
|
Use the [account_info method][] to look up information about the account you got in the previous step. Use a request model like `AccountInfo` to validate the request format and catch errors sooner.
|
||||||
|

### 5. Run the Application
|
||||||
|
|
||||||
{% code-snippet file="/_code-samples/get-started/py/get-acct-info.py" from="# Look up info about your account" language="py" /%}
|
Finally, in your terminal, run the application like so:
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
### 4. Putting it all together
|
|
||||||
|
|
||||||
Using these building blocks, we can create a Python app that:
|
|
||||||
|
|
||||||
1. Gets an account on the Testnet.
|
|
||||||
2. Connects to the XRP Ledger.
|
|
||||||
3. Looks up and prints information about the account you created.
|
|
||||||
|
|
||||||
|
|
||||||
{% code-snippet file="/_code-samples/get-started/py/get-acct-info.py" language="python" /%}
|
|
||||||
|
|
||||||
To run the app, you can copy and paste the code into an editor or IDE and run it from there. Or you could download the file from the [XRP Ledger Dev Portal repo](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/get-started/py) and run it locally:
|
|
||||||
|
|
||||||
|
|
||||||
```sh
|
```sh
|
||||||
git clone git@github.com:XRPLF/xrpl-dev-portal.git
|
python get-acct-info.py
|
||||||
cd xrpl-dev-portal/_code-samples/get-started/py/get-acct-info.py
|
|
||||||
python3 get-acct-info.py
|
|
||||||
```
|
```
|
||||||
|
|
||||||
You should see output similar to this example:

|
The response fields that you want to inspect in most cases are:
|
||||||
|
|
||||||
* `account_data.Sequence` — This is the sequence number of the next valid transaction for the account. You need to specify the sequence number when you prepare transactions. With `xrpl-py`, you can use the [`get_next_valid_seq_number`](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.account.html#xrpl.account.get_next_valid_seq_number) to get this automatically from the XRP Ledger. See an example of this usage in the project [README](https://github.com/XRPLF/xrpl-py#serialize-and-sign-transactions).
|
- `account_data.Balance` — This is the account's balance of [XRP, in drops][]. You can use this to confirm that you have enough XRP to send (if you're making a payment) and to meet the [current transaction cost](../../../concepts/transactions/transaction-cost.md#current-transaction-cost) for a given transaction.

|
- `validated` — Indicates whether the returned data is from a [validated ledger](../../../concepts/ledgers/open-closed-validated-ledgers.md). When inspecting transactions, it's important to confirm that [the results are final](../../../concepts/transactions/finality-of-results/index.md) before further processing the transaction. If `validated` is `true` then you know for sure the results won't change. For more information about best practices for transaction processing, see [Reliable Transaction Submission](../../../concepts/transactions/reliable-transaction-submission.md).
