Configuration ⚙️

Environment Variables (.env)

IMPORTANT: All Extended Exchange API variables MUST start with X10_ prefix:

# Required - Get these from Extended Exchange

X10_PRIVATE_KEY=your_stark_private_key_here  
X10_PUBLIC_KEY=your_stark_public_key_here

⚠️ Note: The X10_ prefix is required for all API-related environment variables. This is a quirk of the Extended Exchange SDK.
