Designed around open standards.
Cylinder uses the open formats and presentation protocols behind digital credential ecosystems. That supports interoperability across compatible credentials and wallets, but it is not a promise of universal coverage.
Built for interoperability
The open standards behind digital credentials and how Cylinder uses them across supported providers and wallets.
- W3C Verifiable Credentials
- OpenID4VP
- OpenID4VCI
- Selective disclosure
The standards we build toward.
How Cylinder uses the open standards behind digital credentials. Standards support does not mean certification or universal compatibility.
W3C Verifiable Credentials
The data model Cylinder is designed around for representing recognised credentials.
OpenID4VP
The presentation protocol Cylinder is building toward for requesting and receiving credentials from supported wallets.
OpenID4VCI
Relevant to the planned issuance product, which is not yet available.
Selective disclosure
Available when the supported credential format and wallet can present only the requested claim.
Supported providers & wallets
Built for interoperability with supported credential providers and wallets.
Standards versioning
Designed to track standards as they evolve rather than pinning to a single revision.
We describe alignment and intent, not accreditation. Cylinder does not claim to be certified to a standard or compatible with every wallet; supported coverage is confirmed with our team for your use case.

Tell us the providers and wallets you need to support, and we will confirm where Cylinder fits today.
