Installation¶

Requirements¶

Python 3.10 or newer
A working C compiler (required by the coincurve dependency)

Install from PyPI¶

pip install o2-sdk

Install from source¶

git clone https://github.com/o2-exchange/sdks.git
cd sdks
pip install -e sdks/python

Development install¶

To install with development dependencies (linting, testing, type checking):

pip install -e "sdks/python[dev]"

Dependencies¶

The SDK uses the following runtime dependencies:

Package	Purpose
coincurve >=20.0.0	secp256k1 elliptic curve cryptography (key generation, signing)
aiohttp >=3.9.0	Async HTTP client for REST API calls
websockets >=12.0	WebSocket client for real-time data streams
pycryptodome >=3.20.0	Keccak-256 hashing (EVM address derivation)

Verifying the installation¶

import o2_sdk
print("o2-sdk installed successfully")

# Quick connectivity check
import asyncio
from o2_sdk import O2Client, Network

async def check():
    client = O2Client(network=Network.TESTNET)
    markets = await client.get_markets()
    print(f"Connected — {len(markets)} markets available")
    await client.close()

asyncio.run(check())
