Your wallet is recoverable through MPC (multi-party computation). One recovery share is backed up to your iCloud/Google account, and one is securely held by Pistachio. Each share is encrypted and useless on its own. Simply reinstall the app on a new device and verify your identity to restore access.

Full explanation:

To enable recovery in case your device is lost or damaged, Pistachio uses a threshold signature scheme (TSS) based on the CGGMP protocol, one of the most battle-tested MPC standards in the industry. Your key is split into two encrypted backup shares:

• One backup share is encrypted and stored in your iCloud or Google Drive

• The second backup share is encrypted and stored by Pistachio

These two shares are part of a 2-of-2 MPC setup and are only used for recovery. They cannot be used for signing transactions, and they cannot be combined to access your wallet without your explicit recovery request. Pistachio is architected to ensure no single party, including us, can reconstruct your key or act without your input.

If recovery is needed, both shares are used to regenerate a new key directly on your new device. The old key is discarded. This way, your wallet remains yours, no seed phrases, no centralized control, and no compromise on security.

MPC gives you the best of both worlds: effortless recovery and uncompromising self-custody.
