Services & Product
Consultancy for teams shipping OpenID4VP, plus a product for teams who'd rather not build it themselves.
Consultancy
Architecture & design review
A structured review of your OpenID4VP flow — authorization request construction, response mode (direct_post / direct_post.jwt), request signing, and response encryption — before it reaches production.
RP registration & ARF certificates
Support navigating the Relying Party registration process defined in the EUDI Wallet Architecture and Reference Framework (ARF) — securing your Registration Certificate with a national registrar and obtaining and managing the Access Certificates used to authenticate OpenID4VP requests to wallets.
Intermediary strategy & setup
The ARF allows a Relying Party to rely on an intermediary to handle the technical interaction with wallets on its behalf. We help you decide whether that model fits your organisation, and can advise on or help stand up the intermediary layer — so your team isn't running OpenID4VP infrastructure directly.
Implementation support
Hands-on help building or debugging wallet, verifier, or issuer components, including presentation exchange and credential format handling (SD-JWT VC, mdoc/mDL).
Security & interoperability review
Independent review against the OpenID4VP threat model and current interoperability test suites, so issues surface before an external audit does.
Standards tracking & training
Briefings and workshops for engineering and product teams tracking OpenID4VP, OpenID4VCI, and the wider eIDAS2 / EU Digital Identity Wallet ecosystem as it evolves.
Product
We're building a focused, standards-based OpenID4VP verification product for teams who need a reliable presentation flow without maintaining a protocol implementation in-house.
It's designed to be usable as an ARF intermediary — so you can rely on it to handle registration, Access Certificate management, and the wallet-facing OpenID4VP exchange, rather than registering and operating that layer yourself.
It's currently in early development. If that's useful to you, get in touch and we'll keep you posted as it takes shape.
