VC Type Metadata Registry

Publish and discover SD-JWT VC Types (VCT). Generate types from issuers or schemas, localize display labels once, and reference a stable URL in your systems.

What you can do

  • Generate VC Types three ways: from an Issuer (OIDC4VCI), from a JSON Schema, or from scratch with assisted AI.
  • Localize once: produce display[] labels/descriptions in up to 30 languages, reuse everywhere.
  • Publish to a registry with a stable URL and integrity hash, or keep private while you iterate.
  • Discover & reuse existing types from the public registry to avoid duplicates.

Who it's for

  • Project managers who need a shared reference for names, fields, and UI labels.
  • CTOs/architects coordinating issuers, wallets, and verifiers across vendors.
  • Integrators aligning schema and UX wording without long back-and-forth.

When to use it

  • Before implementation, to agree on the credential type and UI text.
  • When converging multiple JSON Schemas into a single approved type.
  • When preparing partner documentation and localization.

Generate from an Issuer

Fetch an OIDC4VCI Credential Issuer metadata, select a configuration, and we prefill VCT fields (display, claims, schema...). Support Draft 11 to Finale 1.0.

Import from Issuer →

Generate from JSON Schema

Upload a JSON Schema (2020-12+). We keep property names and help you add multilingual display[].
Add support for 30 languages.

Import Schema →

Start from scratch (with AI)

Describe your credential and target languages; we’ll draft the schema and display[] and let you refine.
Add support for 30 languages.

How it works (at a glance)

  1. Choose a path: Issuer · Schema · From Scratch.
  2. Describe & localize: generate fields and display[] in your target languages.
  3. Review name/description for registry clarity.
  4. Publish or keep private and reference the stable VCT URL when ready.

Standards & interoperability

  • VCT identifier (vct) names the credential type for SD-JWT VC.
  • Type metadata can include schema (validation), display metadata (rendering, multi-language), and claim metadata (selective disclosure hints).
  • Retrieval: from a URL in vct or from a registry; optional integrity via vct#integrity.
  • JSON Schema (2020-12 recommended) for predictability.

SD-JWT VC & VC Type (VCT) Metadata

This registry focuses on SD-JWT VC and the VC Type (VCT) metadata used by wallets and verifiers: schema (validation), display[] (multilingual labels/descriptions), and claim hints for selective disclosure.
