Paradex Python SDK

Paradex Python SDK

Paradex Python SDK provides a simple interface to interact with the Paradex REST and WS API.

Examples

L1 + L2 Authentication (Traditional)

from paradex_py import Paradex
from paradex_py.environment import Environment

paradex = Paradex(env=Environment.TESTNET, l1_address="0x...", l1_private_key="0x...")
print(hex(paradex.account.l2_address)) # 0x...
print(hex(paradex.account.l2_public_key)) # 0x...
print(hex(paradex.account.l2_private_key)) # 0x...

L2-Only Authentication (Subkey)

from paradex_py import ParadexSubkey
from paradex_py.environment import Environment

# Use ParadexSubkey for L2-only authentication
paradex = ParadexSubkey(
    env=Environment.TESTNET,
    l2_private_key="0x...",
    l2_address="0x..."
)
print(hex(paradex.account.l2_address)) # 0x...
print(hex(paradex.account.l2_public_key)) # 0x...
print(hex(paradex.account.l2_private_key)) # 0x...

WebSocket Usage

async def on_message(ws_channel, message):
    print(ws_channel, message)

await paradex.ws_client.connect()
await paradex.ws_client.subscribe(ParadexWebsocketChannel.MARKETS_SUMMARY, callback=on_message)

Using uv

This project uses uv for managing dependencies and building. Below are instructions for installing uv and the basic workflow for development outside of using make commands.

Installing uv

uv is a fast and modern Python package manager. You can install it using the standalone installer for macOS and Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

For other installation methods, refer to the uv installation documentation.

Basic Workflow with uv

If you prefer not to use make commands, you can directly use uv for development tasks:

• Install dependencies: Sync your environment with the project's dependencies.

  uv sync
  

• Run tests: Execute the test suite using pytest within the uv environment.

  uv run pytest
  

• Build the project: Create a distribution package for the SDK.

  uv build
  

For more detailed information on using uv, refer to the uv documentation.

The CI/CD pipeline will be triggered when a new pull request is opened, code is merged to main, or when new release is created.

Notes

[!WARNING] Experimental SDK, library API is subject to change
