Health Checks in your Casa App are an easy way to verify that your keys are available for signing transactions. It's a way to test the integrity of your setup without needing to actually send a transaction. You can health check any of your keys, including the Casa recovery key.
We recommend doing health checks on your setup at least 2 times per year (about once every 6 months).
Mobile and Single Key Health Check
Your Mobile Key (part of the standard multisig wallet) and Single Key (single-signature wallet) are both stored and backup up in a similar way. The keys are stored on your phone, and backed up to your phone's integrated cloud storage.
A health check for the Mobile Key or Single keys does two things:
- Checks to ensure the Mobile/Single Key is on your phone
- Checks to ensure the Mobile/Single Key is properly backed up to your phone's integrated cloud storage service.
To perform a Health Check for your Mobile Key, simply tap the Mobile key icon, then tap "Heath Check."
Hardware Device Key Health Check
Performing a Health Check for your Hardware Device Key prompts you to connect your Hardware Device to create a signature, so you will need access to your Hardware Device (Trezor, Ledger, or Coldcard) to complete the Health Check.
To perform a Health Check for your Hardware Device Key, simply tap the Hardware Device Key icon, then tap "Heath Check."
This will send an email to you, with instructions for connecting the hardware device and adding a signature to verify that it's actively available for signing a real transaction.
NOTE: the health check process for Coldcard is different. See our article on performing health checks for your Coldcard.
Casa Recovery Key Health Check
The Casa Recovery key is the only key in your setup that Casa controls. We strictly limit access to this key internally, store the key offline, and have other security precautions to secure this key on your behalf.
If you ever need to use the Casa Recovery Key at the Gold level of membership (Platinum and Diamond customers can check their recovery status via video verification with our Client Services team), you would answer the security questions you configured when you first set up your app.
When you do a health check for the Casa Recovery Key, you are not verifying the integrity of the key itself (since you don't have access to it), but rather you are verifying that your security questions are correct and recognized by Casa, and that you can answer them if you ever need to.
To perform a Health Check for your Casa Recovery Key, simply tap the Casa Icon from the home screen of your app, then tap "Check Recovery Questions."
That's it! Health checking verifies that when you need to spend funds from Casa, you're able to . Don't forget to do another health check in 6 months!
