Injective Python SDK, with Exchange API Client

Injective Python SDK

Dependencies

Ubuntu

sudo apt install python3.X-dev autoconf automake build-essential libffi-dev libtool pkg-config

Fedora

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

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

2. 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

3. 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:

from pyinjective.async_client_v2 import AsyncClient
from pyinjective.network import Network

async def main():
    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.
