Decision gist · record as of 2026-08-14
Yes. Stellar SDK is actively maintained (last commit 2026-07-27), has no known vulnerabilities, and provides a complete, well-documented interface to the Stellar blockchain. Low install friction, permissive licensing, and broad Python version support make it a solid choice for any Stellar-based Python project. Install with confidence if you need to interact with Stellar.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or higher; PyPy 3.11 is also supported.
- Optional async support and Shamir backup require additional dependencies installed via extras.
- Low friction install with a pure-Python wheel.

What it is and what it does
Stellar SDK is a Python library for building applications on the Stellar blockchain network. It provides networking APIs to communicate with Horizon (Stellar's data API) and Stellar RPC servers, along with tools for constructing, signing, and submitting transactions. The package handles account management, transaction building with various operations (payments, trades, etc.), and network history queries.
The library is designed for developers building Stellar apps in Python and supports modern Python versions (3.10+) and PyPy 3.11. It depends on established packages like pydantic for validation, pynacl for cryptographic signing, requests for HTTP communication, and xdrlib3 for Stellar's data serialization format. Optional async support and Shamir backup functionality are available through extras.
Use it for
- Build and submit payment transactions on the Stellar network from a Python application
- Query account balances, transaction history, and network state via Horizon API
- Create and manage Stellar keypairs and sign transactions for custody or trading workflows
- Integrate Stellar blockchain functionality into a Python backend service or trading bot
- Call Stellar Soroban smart contracts using generated Python bindings

Install
stellar-sdk on PyPI
Before you install
Low friction install with a pure-Python wheel. Actively maintained with recent releases; last commit 2026-07-27. Requires Python 3.10+ or PyPy 3.11. Eight runtime dependencies are all established packages (pydantic, requests, pynacl, etc.), making the dependency tree straightforward.
Requires Python 3.10 or higher; PyPy 3.11 is also supported. Optional async support and Shamir backup require additional dependencies installed via extras.
