Installing

pip install -U stellar-sdk

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

Building transaction with synchronous server

# 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)

• Building transaction with asynchronous server

# Alice pay 10.25 XLM to Bob
import asyncio

from stellar_sdk import Asset, ServerAsync, Keypair, TransactionBuilder, Network
from stellar_sdk.client.aiohttp_client import AiohttpClient

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


async def payment():
    async with ServerAsync(
        horizon_url="https://horizon-testnet.stellar.org", client=AiohttpClient()
    ) as server:
        alice_account = await 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 = await server.submit_transaction(transaction)
        print(response)


if __name__ == "__main__":
    asyncio.run(payment())

Soroban support

As Soroban is still under active development, I have not merged it into the main branch. You can obtain support for it in the soroban branch, but please note that there may be breaking updates at any time before the stable release.

stellar-model

stellar-model allows you to parse the JSON returned by Stellar Horizon into the Python models, click here for more information.
