Aptos SDK
Decision gist · record as of 2026-08-14
Yes, with conditions. Install if you are building on Aptos and need a Python client—the low install friction, active maintenance, and permissive license support that. Do not install for production systems yet; the package is explicitly in development. Avoid the deprecated sync client; use async only for new projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- Local testnet integration requires Aptos CLI and environment variables (APTOS_NODE_URL, APTOS_FAUCET_URL, etc.) for end-to-end testing.
- Low install friction with a pure Python wheel and stable active maintenance.

What it is and what it does
Aptos SDK is a Python library for building applications that interact with the Aptos blockchain. It provides async and sync clients for submitting transactions, querying account state, and interacting with smart contracts deployed on Aptos. The package wraps HTTP and GraphQL communication with the Aptos network, handling cryptographic signing via ecdsa and PyNaCl, and serialization of Move contract calls.
The SDK is actively maintained but explicitly noted as still in development and not recommended for production use. The sync client is deprecated in favor of async-only development. It requires Python 3.9 or later and depends on standard HTTP/crypto libraries (httpx, ecdsa, PyNaCl) plus graphql-client for indexer queries.
Use it for
- Build a Python bot or service that submits transactions to Aptos mainnet or testnet
- Query account balances, transaction history, and smart contract state via GraphQL indexer
- Integrate Aptos blockchain functionality into a larger Python application or web service
- Automate Move contract deployments and function calls from Python scripts
- Test Aptos smart contracts locally using the SDK against a local testnet

Before you install
Low install friction with a pure Python wheel and stable active maintenance. Last commit 2026-08-14 with 6439 repository stars. Note that the sync client is deprecated; new projects should use the async client only.
Requires Python 3.9 or later. Local testnet integration requires Aptos CLI and environment variables (APTOS_NODE_URL, APTOS_FAUCET_URL, etc.) for end-to-end testing.
License in practice
