Keeping a saved copy of your public keys is a necessary step to complete Sovereign Recovery if needed.
"Sovereign Recovery" is what we call the ability to create a transaction outside of Casa App using open-source, third-party tools.
To view the your public key information and instructions you need to carry out Sovereign Recovery:
1. Navigate to your settings in your Casa App
2. Tap "Send Sovereign Recovery info."
This sends you an email with further details on how to recover funds without Casa. The email contains public keys which cannot be used to spend funds, but could be used to view your balance, so you should keep the information contained in that email private.
The email also contains instructions on how you would carry out Sovereign Recovery if needed.
