What's a "health check"?

We’ve built in the Health Checks feature to give you a fast, easy way to verify the integrity of your private keys. With a couple of taps, you can execute a test signature on any of your keys without executing a full transaction. To do this, tap on either the Mobile Key or the Hardware Key in the Basic Multisig screen of your Keymaster app, then tap the “Perform Health Check” button. We recommend running a Health Check for each of your devices once a quarter (4 times a year).
