Hyperliquid SDK

The Hyperliquid SDK is a Python library that allows you to interact with the Hyperliquid protocol. There is the official Python Hyperliquid SDK which we found quite complex and hard to use. So we decided to build our own SDK, which is more user-friendly and easier to use.

Warning: This is an early version of the library. Use with caution and test thoroughly before trading with real funds. Not all features are available yet.

Repository URL:

GitHub - fractrade-xyz/fractrade-hl-simple: Simple API wrapper for automated Perp trading on Hyperliquid DEXGitHub

Installation & Updates

Using pip:

# Install
pip install fractrade-hl-simple

# Update to latest version
pip install --upgrade fractrade-hl-simple

Using poetry:

# Install
poetry add fractrade-hl-simple

# Update to latest version
poetry update fractrade-hl-simple

⚠️ Note: This library is under active development. We recommend updating regularly to get the latest features and fixes.

Setup

1. Create a .env file in your project root:

HYPERLIQUID_ENV=testnet  # or mainnet
HYPERLIQUID_PUBLIC_ADDRESS=your_public_address
HYPERLIQUID_PRIVATE_KEY=your_private_key

We recommend creating a seperate API key wallet in the Hyperliquid UI for automated trading. This API wallets have not withdrawal permissions.

1. Initialize the client:

from fractrade_hl_simple import HyperliquidClient

client = HyperliquidClient()

Authentication Modes

The client can operate in three modes:

1. Authenticated with Environment Variables (Default)

from fractrade_hl_simple import HyperliquidClient

# Automatically loads credentials from .env
client = HyperliquidClient()

2. Authenticated with Explicit Account

from fractrade_hl_simple import HyperliquidClient, HyperliquidAccount

account = HyperliquidAccount(
    private_key="your_private_key",
    env="mainnet",
    public_address="your_public_address"
)
client = HyperliquidClient(account=account)

3. Unauthenticated Mode

If no credentials are available, the client falls back to unauthenticated mode:

# No .env file, no account provided
client = HyperliquidClient()  # Works for public endpoints only

Public vs Private Endpoints

Some methods can be used without authentication:

# These work without authentication
prices = client.get_price("BTC")
balance = client.get_perp_balance("0x123...")  # Requires address
state = client.get_user_state("0x123...")      # Requires address
market_info = client.get_market_info()

Methods that require authentication:

# These require authentication
client.buy("BTC", 0.001)
client.sell("BTC", 0.001)
client.cancel_all()
client.get_positions()
balance = client.get_perp_balance()  # Without address requires auth

The client will automatically warn you when running in unauthenticated mode and help you understand which methods are available.

Basic Usage

Get Market Prices

# Get single price
btc_price = client.get_price("BTC")
print(f"BTC price: ${btc_price:,.2f}")

# Get all prices
all_prices = client.get_price()
for symbol, price in all_prices.items():
    print(f"{symbol}: ${price:,.2f}")

Check Account Balance

balance = client.get_perp_balance()
print(f"Account balance: ${float(balance):,.2f}")

View Positions

positions = client.get_positions()
for pos in positions:
    print(f"Position: {pos.symbol} Size: {float(pos.size):+.3f}")

Place Orders

Market Buy:

order = client.buy("BTC", size=0.001)  # Market buy 0.001 BTC
print(f"Order placed: {order.order_id}")

Limit Buy:

current_price = client.get_price("BTC")
limit_price = current_price * 0.99  # 1% below market
order = client.buy("BTC", size=0.001, limit_price=limit_price)
print(f"Limit order placed: {order.order_id}")

Market Sell:

order = client.sell("BTC", size=0.001)  # Market sell 0.001 BTC
print(f"Order placed: {order.order_id}")

Stop Loss and Take Profit

For Long Positions:

# When you have a long position (bought BTC)
current_price = client.get_price("BTC")

# Place stop loss 5% below entry (sell when price drops)
stop_price = current_price * 0.95
sl_order = client.stop_loss("BTC", size=0.001, stop_price=stop_price)  # is_buy=False by default for long positions

# Place take profit 10% above entry (sell when price rises)
take_profit_price = current_price * 1.10
tp_order = client.take_profit("BTC", size=0.001, take_profit_price=take_profit_price)  # is_buy=False by default for long positions

For Short Positions:

# When you have a short position (sold BTC)
current_price = client.get_price("BTC")

# Place stop loss 5% above entry (buy when price rises)
stop_price = current_price * 1.05
sl_order = client.stop_loss("BTC", size=0.001, stop_price=stop_price, is_buy=True)  # Must set is_buy=True for short positions

# Place take profit 10% below entry (buy when price drops)
take_profit_price = current_price * 0.90
tp_order = client.take_profit("BTC", size=0.001, take_profit_price=take_profit_price, is_buy=True)  # Must set is_buy=True for short positions

The is_buy parameter determines whether the TP/SL order will buy or sell when triggered:

• For long positions: use is_buy=False (default) to sell when triggered

• For short positions: use is_buy=True to buy when triggered

Open Position with TP/SL

Alternatively, you can use the convenience methods that handle both entry and TP/SL orders:

Long Position:

current_price = client.get_price("BTC")
position = client.open_long_position(
    symbol="BTC",
    size=0.001,
    stop_loss_price=current_price * 0.95,  # 5% below entry
    take_profit_price=current_price * 1.10  # 10% above entry
)
print(f"Entry order: {position['entry'].order_id}")
print(f"Stop loss: {position['stop_loss'].order_id}")
print(f"Take profit: {position['take_profit'].order_id}")

Short Position:

current_price = client.get_price("BTC")
position = client.open_short_position(
    symbol="BTC",
    size=0.001,
    stop_loss_price=current_price * 1.05,  # 5% above entry
    take_profit_price=current_price * 0.90  # 10% below entry
)

These methods automatically set the correct is_buy parameter for TP/SL orders based on the position direction.

Close Position

close_order = client.close("BTC")
print(f"Position closed with order: {close_order.order_id}")

Cancel Orders

# Cancel orders for specific symbol
client.cancel_all_orders("BTC")

# Cancel all orders across all symbols
client.cancel_all()

Complete Trading Example

Here's a full example showing a basic trading flow:

from fractrade_hl_simple import HyperliquidClient
import time

def main():
    client = HyperliquidClient()
    SYMBOL = "BTC"
    POSITION_SIZE = 0.001
    
    try:
        # Check current price
        price = client.get_price(SYMBOL)
        print(f"Current {SYMBOL} price: ${price:,.2f}")
        
        # Place limit buy order
        limit_price = price * 0.99  # 1% below market
        order = client.buy(SYMBOL, POSITION_SIZE, limit_price=limit_price)
        print(f"Limit order placed: {order.order_id}")
        
        time.sleep(2)
        
        # Cancel limit order if not filled
        client.cancel_all_orders(SYMBOL)
        
        # Open market position
        order = client.buy(SYMBOL, POSITION_SIZE)
        print(f"Position opened with order: {order.order_id}")
        
        # Check position
        positions = client.get_positions()
        position = next((p for p in positions if p.symbol == SYMBOL), None)
        if position:
            print(f"Current position: {float(position.size):+.3f} {position.symbol}")
            print(f"Entry price: ${float(position.entry_price):,.2f}")
            print(f"Unrealized PnL: ${float(position.unrealized_pnl):,.2f}")
        
        # Close position
        close_order = client.close(SYMBOL)
        print(f"Position closed with order: {close_order.order_id}")
        
    except Exception as e:
        print(f"Error: {str(e)}")
        # Cleanup
        client.cancel_all_orders(SYMBOL)
        client.close(SYMBOL)

if __name__ == "__main__":
    main()
