Reference authority surfaces on KYE™.

Connector Hub™ integrates KYE™. App Store productises KYE™. Plugin Marketplace™ extends KYE™.

Illustrative — the authority + evidence record KYE Protocol™ produces for a single governed action (sample data).

Mobile demo · the user-facing showcase

KYE™ Authority Wallet™ — control AI agents from your phone.

An Android / iOS demo (Expo / React Native) that turns the protocol into an experience. Create AI agents, grant scoped authority, approve / deny / revoke, inspect Decision Maps™, view Evidence Packs™. Synthetic data; simulated agent and payment flows.

• Flagship scenario: Let an AI shopping agent buy on my behalf, but only up to £50, only from approved merchants, and require my approval above £25. The phone receives a request for £34.99 and asks approve / deny / modify scope / revoke.
• Six screens: Home, Agent (with revoke + cascade demo), Approval, Decision Map™, Evidence Pack™, Developer mode (request / decision / evidence / webhook JSON + TS SDK snippet).
• Five demo scenarios shipped: agent-backed purchasing, travel booking, open-banking payment-prep, healthcare appointment booking, legal contract approval, security key rotation.
• Demo vs Pro: the demo is proprietary and runs on synthetic data. The production version — KYE™ Authority Wallet Pro™ — ships real Gateway integration, enterprise approvals, push notifications, evidence archive (commercial). Banks and payment platforms get KYE™ Mobile Approval Gateway™.

Demo app uses synthetic data and simulated agent / payment flows. It does not process real payments or replace bank, wallet, legal, healthcare, or identity systems.
