Frequently asked questions
The questions we get most often, and the current limitations, plainly stated.
What does Todis actually verify?
That the proof presented by a user's digital identity wallet is genuine (signed by a recognized issuer and still valid), without ever showing you more information than what you asked for.
Do I need to become a qualified trust service provider myself?
No. You remain a simple relying party. That's exactly Todis's role: doing the cryptographic verification on your behalf.
Which wallet formats are supported?
Both main formats of the EUDI Wallet ecosystem: SD-JWT VC (fully automatic issuer verification) and mdoc/ISO 18013-5 (notably used for mobile driving licenses, which currently requires you to send us the relevant issuer's certificate before going live, contact us).
Which countries are covered?
Todis automatically verifies issuers from every EU/EEA member state via the official registry published by the European Commission, updated live, with no action needed on our part. Compatibility for a specific country may vary due to local technical specifics; if a particular country is critical for your use case, contact us and we'll verify it before you go live.
What data do you see about my users?
With self-hosting, none: verification runs entirely on your own infrastructure, nothing transits through us. In hosted mode, the proof transits through our servers for the duration of the verification (never stored, never logged, never reused), and we only pass you what you explicitly asked for, thanks to selective disclosure (a visitor can, for example, prove they're of age without revealing their full date of birth).
Can I self-host the service?
Yes, via the Premium plan (annual license from €4,500, with no per-request billing since we have no way to measure your usage in that case). Your verification data never transits through our servers if you choose self-hosting.
Do I need to register somewhere to use the service?
Not today. The European framework (eIDAS 2.0) plans that, eventually, every relying party will need to register with a national authority to query a citizen's production wallet, but this infrastructure isn't open yet in member states. We're following this closely and will guide you through it when the time comes.
How does billing work?
Three simple plans, no commitment to get started: see the pricing page.
