You hold the key, but if you lose that key, you’ve lost your bitcoin. A single mistake means your hard-earned savings disappear.

Exchanges hold your bitcoin key for you, so your account is susceptible to hacks, phishing, or insider theft.
Casa is the world’s first personal key manager.
It’s a simple, secure way to hold your own keys with peace of mind that your bitcoin is safe. Here’s how we do it.
Most wallets are a single point of failure.
Most wallets use only one key, which doesn’t adequately protect your bitcoin from loss or theft. If you lose that key, your bitcoin is gone.

Lose a key? Not a problem.
Three keys protect your bitcoin, but you only need two to spend it. A lost key doesn’t mean lost bitcoin, since you still have two keys left.

Designed to be durable.
If you do lose a key or have one stolen, you can swap it out for a new one. Simply transfer your bitcoin to the new, healthy set of keys using your two remaining keys from the initial set. Casa App walks you through it all, step by step.

Each key is held on a different device—a mix of your phone and offline hardware wallets. Casa supports wallets from Trezor, Ledger, and Coldcard.

Each key is stored in a different location. That makes it nearly impossible for a thief or natural disaster to cause you to lose more than one key at a time.
