Yebo Trust Score

A behavioral authorization history, portable across every AI tool you use. Built from real authorization signals, not social data, not financial history.

Authorization history, not social scoring

The Yebo Trust Score measures the quality of your authorization behavior, how many mandates you've completed cleanly, whether Sentinel has ever blocked an action, whether your agents have stayed within their declared scopes.

It is derived entirely from your activity on the Yebo authorization network. No email, phone number, social profile, or financial data is ever used. No AI company can replicate it because it requires being the authorization infrastructure , not just one model's output.

As your score grows, Yebo reduces friction for low-risk repeat actions , so trusted users spend less time on biometric prompts for things they do every week.

INV-12, Non-negotiable

The Trust Score may reduce friction for low-impact repeat actions. It never replaces biometric authorization for high-impact actions. This invariant is enforced by Sentinel and cannot be overridden by policy.

Signal Weights

Every authorization event generates behavioral signals. Positive signals increase your score; violations decrease it. The score is a weighted sum normalized to 0–100.

Nonce was unique, no replay attack attempted

positive

settlement_matched

Settlement confirmed and matched to mandate

positive

enterprise_verified
