KYE App Store™ · production-ready apps

Deploy authority-aware apps that already exist.

The KYE App Store™ is for full apps built on KYE Protocol™ — not just connectors and not just plugins. Each one is a productised surface a bank, enterprise, consultant, auditor, or developer can deploy. Schemas, sample payloads, manifest, webhook verifier, and SDK adapters are open. The runtime gateway, evidence engine, dashboards, and SLA-backed delivery are commercial.

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