Hey there, let's work through this import issue step by step! You mentioned running into errors when trying to import Keypair from both solana.keypair and solders.keypair, and your end goal is to build a script to connect to a Phantom wallet. Here are some troubleshooting tips and alternatives to help you out:

• First, double-check your dependency installations

  • For the official solana-py library, make sure you've installed (or upgraded to) the latest stable version with:

    pip install --upgrade solana
    

  • If you're using solders, confirm you've installed it correctly—sometimes cached builds or version mismatches cause issues. Try a clean install:

    pip uninstall -y solders
    pip install --no-cache-dir solders
    

    You can also specify a known stable version (like 0.18.0) if the latest version has breaking changes:

    pip install solders==0.18.0
    

• Verify your import paths match the library versions

  • For modern solana-py, from solana.keypair import Keypair is the correct import. If you still get an error, check if you're using the right Python environment—sometimes libraries install to a global Python instance instead of your virtual environment. Activate your venv first before installing dependencies!
  • For solders, from solders.keypair import Keypair is indeed the right path. If this fails, check your Python version (both libraries require Python 3.8+; run python --version to confirm).

• Consider your actual use case: Connecting to Phantom Wallet
  Quick note—if you're building a script to interact with Phantom, you might not need to import Keypair directly in your Python code. Phantom wallet connections typically happen via a frontend (using JavaScript/Web3.js) where the user authorizes access. Your Python backend can then handle signed transactions sent from the frontend using solana-py's Client and transaction utilities.

• Dig into the specific error message
  If you haven't already, take a close look at the exact error you're getting:

  • ModuleNotFoundError: Means the library isn't installed in your current environment.
  • ImportError: cannot import name 'Keypair': Means the library version you're using has changed the import path for Keypair (check the library's release notes for updates).
