# Payment Wallet Attestation credential schema ## When to use Use this skill when you issue or ask for a **Payment Wallet Attestation**. The registry titles the credential **Payment Authenticator (v2)**. It attests one payment instrument that the wallet holds: the card scheme, the currency, the issuer identification number, and the truncated card and reference numbers. The credential never carries the full card number. The credential is also the input of the transaction data validation operation of the OpenID4VC API, which takes a `paymentWalletAttestation` field. The registry publishes this schema in **one format only: `dc+sd-jwt`** (SD-JWT VC). The metadata sets `isSdJwt` to `true`, and `isJwt` and `isMsoMdoc` to `false`. There is no JWT form and no mdoc form of this schema in the registry. This page describes registry version **2025.3.1**, the latest version of the template. ## Prerequisites - An **iGrant.io Organisation Wallet Suite (OWS) API key**. Get it from [support@igrant.io](mailto: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. ## Ask the integrator first Ask one question at a time. Wait for the answer. Give the recommended default with each question. Lo
