13.2 PTERI Wallet App

PTERI Wallet App

The PTERI Wallet is the core client application used for identity verification, authentication, and transaction authorization within the PTERI platform.

Unlike traditional wallets, the PTERI Wallet functions as a universal trust device used for:

• Identity verification

• Secure authentication

• Transaction approvals

• Cryptographic authorization

All private keys are generated and stored locally on the user’s device.

Key Capabilities

Cryptographic Authentication

Users authenticate by signing challenges with their wallet keys.

This replaces traditional authentication systems such as:

• Passwords

• SMS codes

• Authenticator apps

Authentication becomes cryptographic proof of authority.

---

Self-Custody Identity

The wallet ensures:

• Keys remain on the user device

• Biometrics protect key access

• No centralized storage of credentials

The platform infrastructure can verify signatures but cannot impersonate users.

---

Payments & Authorization

The wallet can authorize:

• Litecoin transactions

• Payment approvals

• Identity-bound intent signing

This allows a single wallet to secure:

• login

• payments

• AI agent authority

• API access
