• Multiple triggers – HTTP, timers, manual actions, forms, wallet interactions

• Extensive action library

  • Issue, verify, and revoke W3C Verifiable Credentials
  • Create, update, and deactivate Decentralized Identifiers (DIDs)
  • Send HTTP requests, emails (SendGrid), DIDComm messages, and JWTs
  • Custom validation using business rules

• Multi‑tenant by design – clean separation of organizational data

• Visual designer – drag‑and‑drop UI for building workflows

• Extensible & secure – written in modern .NET with a plug‑in architecture
