Creating Watch-Only Wallets

We built Casa to protect our clients from every risk imaginable.

That includes us.

As we all know, trusted third parties are security holes. That’s why Casa has never - and will never - claim to be one.

What’s a watch-only wallet?

Watch-only wallets provide Bitcoiners with the means to safely monitor their balances and transactions, but only spend funds if hardware wallets are available.

They’re typically used for keeping an eye on cold storage funds or paper wallets, and can be created using public keys without ever needing to touch your private keys.  

Why do they matter?

As a Casa member, you can use a watch-only wallet to verify that the deposit addresses the Casa App is presenting to you are in fact controlled by your keys. This provides added assurance that you’re safe from a man-in-the-middle attack (e.g. a malicious code update misdirecting you to send BTC to an address controlled by another party).  These attacks are rare, and we do everything in our power to protect our clients from them.  By following these guides, you can also verify this personally.

Wrapping Up

Open source security is a team sport.

If you’re worried about what could happen should Casa ever be compromised, unavailable, or under attack, that means you're thinking about your security the same way we do every day. Using open source software like Electrum to verify your balances and receive addresses entirely outside of our systems helps maximize your personal sovereignty, and provides an important check on Casa. It's part of our "Can't Be Evil" design.

Still worried about your Bitcoin?
