iGrant.io verifier frontend (OpenID4VP + DCQL)

When to use

Build the relying-party UI: request a verifiable presentation, let the user scan a QR (or use the same-device wallet), and show the disclosed claims and the verified decision the instant the wallet responds. Depends on igrantio-frontend-client (vendored at src/lib/ows/) and an igrantio-verifier-backend deployment. Issuer UI is a separate skill (igrantio-issuer-frontend).

Prerequisites

• An iGrant.io Organisation Wallet Suite (OWS) API key. Get it from support@igrant.io. Keep it on the server, in an environment variable or a secret manager. The browser never sees it.
• The OWS environment the key belongs to. The default is demo (https://demo-api.igrant.io). Use staging (https://staging-api.igrant.io) only when the integrator asks for it. A key works only in its own environment.
