Casa
Multisig self-custody with concierge support — keys stay yours, Casa helps you not lose them.
Casa offers multisig self-custody with a guided app and human support. Your bitcoin is secured by multiple keys spread across your phone, hardware devices and Casa itself, so no single lost key — and no single company — can move your funds. Recovery, inheritance planning and health checks are built into the product.
It is aimed squarely at people holding meaningful amounts who want the security of multisig without assembling it by hand. You still hold your keys, which is the whole point; what you pay for is the concierge experience and the confidence that you can recover if something goes wrong.
