# 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.
