PTERI Wallet — features and security architecture

In PTERI Wallet

The PTERI Wallet functions as a universal trust device. It replaces passwords, SMS codes, and authenticator apps with secure cryptographic authentication.

Key features

  • Biometric / FIDO2 unlock — no passwords, ever
  • Zero-custody keys — you control your private keys; they never leave the device
  • Hardware-backed storage when the device supports it
  • MWEB privacy toggle for confidential transactions
  • Self-custody Litecoin (LTC) wallet

How verification works

Authentication follows a three-step flow:

  1. You sign a challenge in the wallet
  2. The app sends the signature to the PTERI API
  3. The API verifies the signature and grants access

Platform infrastructure can verify signatures but can never impersonate you — keys remain locally stored and verification settles deterministically via the Litecoin blockchain.
