You hold the keys.
Here is exactly how that works.

SciPHR is the first decentralized Key Management System, a dKMS for the enterprise. It upgrades an ordinary wallet into a Personal Identity xCIPHR: a self-custodial credential whose keys are generated and held on your own device, that nobody but you can sign with, and that no custodian ever holds. These docs explain what we built, how the cryptography fits together, and why each decision was made.

[ 01 ]SciPHR in a minute

The plain-language version.

Skip the jargon for a moment. Three things happen, and you stay in control through all of them.

[ 01 ]
You mint a xCIPHR.
Your wallet is generated on your device, and its master key is sealed into an encrypted backup envelope anchored by an NFT on the XRP Ledger. The keys are born on the phone and never travel in plain text.
[ 02 ]
You authenticate.
A glance at Face ID proves the device is yours, and the chip itself signs the proof. The signature is produced on the phone, in hardware you already carry.
[ 03 ]
You manage access.
Grant, rotate, and revoke permissions enforced on-chain. Add a new device, retire an old one, without ever exposing or copying a key.

The core idea

A custodian holds your keys for you. With SciPHR, your keys are generated and stored on your own device, and your master key is backed up as sciphrtext only your device, your iCloud, or your recovery code can open. No SciPHR operator can sign for you or open your backup, and because our backend holds no such key, you can verify how custody works by reading the code. We call this true self-custody.
