Get Started

This guide will walk you through the essential steps to start using the HyperETH Trading API with Hyperliquid.

1. Create Hyperliquid Master Account

First, you need to create a Hyperliquid master account which will serve as your primary trading account.

Prerequisites

• Get a master account
  • Visit Hyperliquid to login via Privy, or
  • Download Metamask or other wallet extensionson to create a master account
• Obtain USDC on the Arbitrum network for trading

Account Creation Steps

1. Get USDC: You'll need USDC on the Arbitrum network to trade on Hyperliquid. You can buy or transfer USDC to your wallet.

2. Connect to Hyperliquid:

   • Visit app.hyperliquid.xyz
   • Connect your master account, if you choose to use privy in hyperliquid, then you don't need to connect to your wallet extension
   • Deposit your USDC to start trading

2. Create Agent Wallet

Agent wallets (also known as API wallets) allow your master account to authorize API access for programmatic trading without withdrawal permissions.

Creating an Agent Wallet

1. Access API Page: Visit app.hyperliquid.xyz/API

2. Generate Agent Wallet:

   • Click on "Generate" to create a new agent wallet
   • Name your API key for easy identification
   • Save the generated private key securely - you'll need this for API calls

3. Important Notes:

   • Each trading process should use a separate agent wallet for better nonce management
   • Agent wallets can only sign transactions, not withdraw funds
   • Multiple subaccounts benefit from separate agent wallets for parallel operations

3. Approve Agent Wallet

After creating your agent wallet, you need to approve it for trading operations.

Approval Process

1. Navigate to API Settings: In the Hyperliquid interface, go to your API settings
2. Authorize Agent Wallet: Find your newly created agent wallet and click "Authorize"
3. Confirm Authorization: Complete the authorization process to enable trading permissions

Verification

• Verify the agent wallet appears in your authorized API wallets list
• Test basic API connectivity using the agent wallet credentials

4. Using Agent Wallet for Trading

Once your agent wallet is approved, you can start making API calls to execute trades.

info = Info(base_url="https://api.hypereth.io")
exchange = Exchange(account, base_url="https://api.hypereth.io")

# Place a market order
order_result = exchange.market_open(
    coin="BTC",
