Fedora

sudo dnf install python3-devel autoconf automake gcc gcc-c++ libffi-devel libtool make pkgconfig

macOS

Quick Start

Installation

pip install injective-py

Usage

Requires Python 3.9+ Please install poetry following the steps described in the documentation

Examples

$ poetry install
# connecting to Injective Exchange API# and listening for new orders from a specific spot market
$ poetry run python examples/exchange_client/spot_exchange_rpc/8_StreamOrderbookUpdate.py
# sending a msg with bank transfer# signs and posts a transaction to the Injective Chain
$ poetry run python examples/chain_client/bank/1_MsgSend.py

Upgrade pip to the latest version, if you see these warnings:

WARNING: Value for scheme.platlib does not match. Please report this to <https://github.com/pypa/pip/issues/10151>
WARNING: Additional context: user = True home = None root = None prefix = None

Development

  1. Generate proto binding & build
make gen
poetry build
  1. Install pkg
# from local build
pip uninstall injective-py
pip install injective-py --no-index --find-links /path/to/injective/sdk-python/dist
# from pypi
pip uninstall injective-py
pip install injective-py
  1. Run all unit tests in a development environment
poetry run pytest -v

Maintainers: see MAINTAINERS.md for how to regenerate proto bindings, refresh pyinjective/ofac.json, and cut a new release.


Async client (exchange V2)

The Injective Python SDK exposes AsyncClient from the async_client_v2 module:

  • Import using: from pyinjective.async_client_v2 import AsyncClient
  • Example:
frompyinjective.async_client_v2importAsyncClientfrompyinjective.networkimportNetworkasyncdefmain():
client=AsyncClient(network=Network.mainnet())
# Or use testnet# client = AsyncClient(network=Network.testnet())

Market Format Differences:

  • V1 AsyncClient: Markets are initialized with values in chain format (raw blockchain values)
  • V2 AsyncClient: Markets are initialized with values in human-readable format (converted to standard decimal numbers)

Exchange Endpoint Format Differences:

  • V1 Exchange endpoints: All values (amounts, prices, margins, notionals) are returned in chain format
  • V2 Exchange endpoints:
    • Human-readable format for: amounts, prices, margins, and notionals
    • Chain format for: deposit-related information (to maintain consistency with the Bank module)

Important Note: The ChainClient (V1) will not receive any new endpoints added to the Exchange module. If you need access to new exchange-related endpoints or features, you should migrate to the V2 client. The V2 client ensures you have access to all the latest exchange functionality and improvements.
