GitHub Workflow Status Read the Docs PyPI - Downloads Code Climate maintainability Codecov PyPI Python - Version PyPI - Implementation Stellar Protocol

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

pip install --upgrade stellar-sdk

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

pip install --upgrade stellar-sdk[aiohttp]

We follow Semantic Versioning 2.0.0, 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

# 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)
