2.1 PTERI Wallet — Self-Custody Identity

At the center of PTERI is the PTERI Wallet.

The wallet is not an accessory.
It is the identity anchor.

The mental model

A passport locked in your pocket is identity.
A photocopy stored in someone else’s database is not.

The PTERI Wallet enforces this distinction at the architectural level.

What the wallet does

• Generates cryptographic keys on the device
• Stores keys in hardware-backed secure storage
• Uses biometrics to gate key usage, not key storage
• Signs messages, challenges, and transactions locally

What the wallet never does

• Keys never leave the device
• Seed phrases are never uploaded
• Biometrics are never transmitted
• Kakr never sees secrets

This is enforced by design, not policy.

Not your keys, not your coin is not a slogan here — it is a constraint.
