Authenticated Setup

Public reads and public streams can use public=True without credentials:

from hyperliquid import Hyperliquid

async with Hyperliquid.http(public=True) as client:
  mids = await client.info.all_mids()

Otherwise, we recommend using "API wallets" instead of your actual private key. You can create them from the Hyperliquid website.

Authorize the API wallet and then copy the private key, as shown in the screenshot below:

Environment Variable

For authenticated exchange actions, set your private key:

export HYPERLIQUID_PRIVATE_KEY="api_wallet_private_key"

Then construct Hyperliquid normally:

from hyperliquid import Hyperliquid

async with Hyperliquid.http() as client:
  result = await client.exchange.noop()
  print(result['status'])

For testnet, pass mainnet=False and set the testnet key:

export HYPERLIQUID_TESTNET_PRIVATE_KEY="testnet_private_key"

from hyperliquid import Hyperliquid

async with Hyperliquid.http(mainnet=False) as client:
  result = await client.exchange.noop()
  print(result['status'])

Direct Wallet Usage

You can also pass a private key or wallet object directly:

from hyperliquid import Hyperliquid

async with Hyperliquid.http('0xyour_private_key') as client:
  result = await client.exchange.noop()
  print(result['status'])

Security Notes

• Never commit private keys.
• Treat HYPERLIQUID_PRIVATE_KEY and HYPERLIQUID_TESTNET_PRIVATE_KEY as high-sensitivity secrets.
• Treat exchange examples as mainnet-sensitive unless you explicitly set mainnet=False.
