11.2 Step-Up Authentication for Sensitive Actions

Problem​

Sensitive actions (role changes, payouts, deletions) often rely on:

  • Re-entering passwords
  • SMS or email confirmations

These are weak under automation and phishing.

PTERI Approach​

  • Generate a fresh challenge
  • Require a new wallet signature
  • Verify before executing the action

Each high-risk action requires explicit, local approval.

There is no concept of “already trusted”.
