"What happens to my bitcoin if Casa disappears?" is one of the most common questions we get, and you can answer it for yourself in about two minutes. Open your vault in the Casa app, tap Deposit Funds, and export the wallet descriptor. Load it into Sparrow and your vault reappears outside our app, with the same policy and the same addresses down to the first one on the list. The descriptor tells any wallet where your bitcoin lives. The keys you hold are what move it. Every vault comes with a Casa key which is never required to move your bitcoin. The Casa key exists to help you recover your vault if you lose a key and to make signing easier.
