⚠️ Security Considerations

Third-Party Dependencies

This skill can work with just requests library for read-only operations. For signing orders, you have two options:

Option A: Minimal (Read-Only)

pip install requests

Only for public data (markets, order books, prices).

Option B: Full Trading Requires the official Lighter SDK. Review and verify before installing:

• SDK Repository: https://github.com/elliottech/lighter-python
• Verify the repository owner, stars, and code before running any setup

External Code

Only proceed with external SDK if you:

1. Have reviewed the GitHub repository
2. Understand what the code does
3. Use a dedicated burner wallet, not your main wallet
