And then execute:

$ bundle install

Or install it yourself as:

$ gem install hyperliquid

require 'hyperliquid'

# Create SDK instance for read-only operations (mainnet by default)
sdk = Hyperliquid.new

# Or use testnet
testnet_sdk = Hyperliquid.new(testnet: true)

# Access the Info API (read operations)
info = sdk.info

# For trading operations, provide a private key
trading_sdk = Hyperliquid.new(
  testnet: true,
  private_key: ENV['HYPERLIQUID_PRIVATE_KEY']
)

# Access the Exchange API (write operations)
exchange = trading_sdk.exchange
