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.
