Casa is the best personal key system on the planet.

Securing your private keys is essential to safely managing your Bitcoin. Casa provides the most secure, user-friendly solution for truly securing your digital savings.


- The Casa app uses multi-sig to help you secure your funds better than any other wallet.
- Sending any funds from your multi-sig keys requires approving the transaction from multiple hardware devices, significantly increasing security.
- With most wallets, losing a private key means your crypto is lost forever. With Casa, you can you can still recover your funds with the remaining keys in your multi-sig keyset. Just replace your lost device and you're good to go.
- Casa holds one key for you in case of emergency. It's only one key, so we can't move your funds ourselves, but we can help you recover them if you lose a key.


- The Casa Mobile Key is a single signature keyset. Sending funds only requires approval from your phone.
- This allows for faster, more convenient transactions. But the tradeoff is lower security than your multi-sig keyset. We strongly recommend keeping the majority of your funds secured with multi-sig, and only a small portion in the mobile keyset.
- The mobile key is seedless. Instead of backing it up with a seed phrase, it's backed up with a combination of security from iCloud and Casa. Your key is stored in the secure enclave, then encrypted with a key from Casa. The encrypted key is then stored in your iCloud, so if you lose your phone you can recover the key as long as you still have access to your iCloud account and your Casa account. The key never touches Casa servers, and Casa has no access to the unencrypted key.


- We have removed all third-party tracking except Firebase crash reporting. In place of this, we've added a "Sovereign Logs" feature which allows you to send us troubleshooting logs when you're having an issue. This significantly increases user privacy by only allowing detailed app logging when YOU turn it on. We'll be adding our own automatic crash reporting in the future to completely remove Firebase.
- All features and updates are made with your security, privacy, and sovereignty as the highest priority.
- Our Client Services team is ready to support you with any questions you have as you secure your assets and data.

Our world is rocketing toward a future full of digital money and assets. Casa is a home for the keys that will secure your future savings. Join us and take steps toward becoming a true sovereign individual.
