After replacing a key in your Casa app, addresses generated by your Casa app will be for the new wallet or vault. It is important that you update any saved or "whitelisted" addresses you have stored to an address from the new vault:
- Scheduled or repeating purchase or withdrawal services
- Mining services
If you have set up a watch-only wallet for your vault or entered the extended public key for your Pay wallet anywhere, you will need to reconfigure these with the new key, being especially mindful of any changes to derivation paths.
