Designed around open standards.
Interoperability is what keeps digital credentials trustworthy and portable. Cylinder is built to align with the open standards the ecosystem depends on — described carefully, without overstating certification or coverage.
Built for interoperability
The open standards the digital credential ecosystem runs on, and how Cylinder is designed to align with them across supported providers and wallets.
- W3C Verifiable Credentials
- OpenID4VP
- OpenID4VCI
- Selective disclosure
How Cylinder aligns with the open standards behind digital credentials. Language here is deliberate — designed around and intended to support, not certified or universally compatible.
W3C Verifiable Credentials
The data model Cylinder is designed around for representing recognised credentials.
OpenID4VP
Intended to support OpenID for Verifiable Presentations for how credentials are presented.
OpenID4VCI
Intended to support OpenID for Verifiable Credential Issuance across the ecosystem.
Selective disclosure
A first-class capability — sharing only the fact required, not the whole credential.
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.
