Why desktop
Built for the moments your Bitcoin matters most.
A bigger canvas for big decisions
Read every transaction detail clearly before you sign — no squinting at small screens.
A safer signing environment
Desktop reduces exposure to mobile-specific threats and untrusted networks.
Total control over your keys
Coordinate multisig setups across devices with full visibility and clarity.
Reduce mobile risk
Move long-term storage off your phone and into a hardened workstation.
Core security
The architecture of true ownership.
Engineered from the ground up to remove single points of failure — including yourself.
Multi-Signature Vaults
2-of-3 and 3-of-5 setups eliminate single points of failure. No one key — not even yours — can move funds alone.
Distributed Key Storage
Spread your keys across devices, locations, and trusted hardware. Geographic redundancy by design.
Transaction Transparency
Every signing request is rendered in plain language. See exactly what you're approving — every time.
Hardware Wallet Native
First-class support for Ledger, Trezor, Coldcard, Keystone, and Passport. Bring the wallets you trust.
Built for generations
Pass it on without passing the keys.
Most self-custody dies with its owner. Casa's inheritance system makes sure your bitcoin reaches the people who matter — securely, privately, and without a single seed phrase ever leaving your control.
- Secure inheritance planning, baked in
- No private keys ever exposed to heirs
- Step-by-step guided recovery for family
- Prevents permanent loss across generations
