A wallet your phone generates on its own.

Most wallets arrive already made. A server or app generates the keys and passes them down, so something other than your device saw the secret when it was created.

SciPHR generates the XRP Ledger keys on your iPhone, stores them in the iOS Keychain, and releases them only behind a live Face ID. The backend receives no seed and holds no key that can sign. It prepares an unsigned transaction and broadcasts the one your device signs.

Picture a key cut inside your own house, where the locksmith mails you the blank and never sees the finished cut. If the maker never touched the working key, there is nothing on their side to steal or surrender.

A key generated on the device that keeps it makes custody something you can verify, not something you have to trust.
