py-stellar-base is a Python library for communicating with
a `Stellar Horizon server`_ and `Soroban-RPC server`_. It is used for building Stellar apps on Python. It supports **Python 3.8+** as
well as PyPy 3.8+.

It provides:

- a networking layer API for Horizon endpoints.
- a networking layer API for Soroban-RPC server methods.
- facilities for building and signing transactions, for communicating with a Stellar Horizon and Soroban-RPC instance, and for submitting transactions or querying network history.

Documentation
-------------
py-stellar-base's documentation can be found at https://stellar-sdk.readthedocs.io.

Installing
----------

.. code-block:: text

    pip install --upgrade stellar-sdk

If you need to use asynchronous, please use the following command to install the required dependencies.

.. code-block:: text

    pip install --upgrade stellar-sdk[aiohttp]

We follow `Semantic Versioning 2.0.0 <https://semver.org/>`_, and I strongly
recommend that you specify its major version number in the dependency
file to avoid the unknown effects of breaking changes.

A Simple Example
----------------
You can find more examples `here <https://github.com/StellarCN/py-stellar-base/tree/main/examples>`__.

.. code-block:: python

    # Alice pay 10.25 XLM to Bob
    from stellar_sdk import Asset, Server, Keypair, TransactionBuilder, Network

    alice_keypair = Keypair.from_secret("SBFZCHU5645DOKRWYBXVOXY2ELGJKFRX6VGGPRYUWHQ7PMXXJNDZFMKD")
    bob_address = "GA7YNBW5CBTJZ3ZZOWX3ZNBKD6OE7A7IHUQVWMY62W2ZBG2SGZVOOPVH"

    server = Server("https://horizon-testnet.stellar.org")
    alice_account = server.load_account(alice_keypair.public_key)
    base_fee = 100
    transaction = (
        TransactionBuilder(
            source_account=alice_account,
            network_passphrase=Network.TESTNET_NETWORK_PASSPHRASE,
            base_fee=base_fee,
        )
        .add_text_memo("Hello, Stellar!")
        .append_payment_op(bob_address, Asset.native(), "10.25")
        .set_timeout(30)
        .build()
    )
    transaction.sign(alice_keypair)
    response = server.submit_transaction(transaction)
    print(response)

stellar-model
-------------
stellar-model allows you to parse the JSON returned by Stellar Horizon
into the Python models, click `here <https://github.com/StellarCN/stellar-model>`__ for more information.
