iGrant.io holder backend (wallet side: receive, hold, present)

When to use

Build or extend the server that a holder (wallet) frontend talks to - the organisation is the wallet that receives and presents credentials, e.g. a European Business Wallet. It composes igrantio-backend-proxy (holder allow-list) + the igrantio-holder-notifications SSE relay. For the other two roles use igrantio-issuer-backend / igrantio-verifier-backend. Read igrantio-ows-overview first; the exact holder endpoint contract lives in references/holder-api-reference.md.

Before you build: run the integrator intake in igrantio-ows-overview - environment, API key, tenancy, backend host, webhooks, frontend - one question at a time, a recommended default with each. (Webhooks: not needed for the holder role - notifications replace them.)
