Credential Verification

Verify a Credostar credential.

Every credential issued through Credostar carries a unique verification URL and (on Premium and Blockchain tiers) a QR code. Public verification opens to everyone at our Q3 2026 launch. Until then, this page explains what verification looks like and where to direct credentials issued through the design partner pilot.

Verification opens publicly with the Q3 2026 launch. Design partners get earlier access.

How verification works

Open by design.

Credostar credentials are W3C Verifiable Credentials. Verification is a property of the credential itself, not of our servers.

  • Cryptographic signature

    Every credential is signed with the issuer’s private key at issuance time. Tampering invalidates the signature.

  • Verifier-agnostic

    Any W3C VC compliant verifier (including open-source ones) can validate a Credostar credential without contacting us.

  • Portable forever

    The proof travels with the credential. Recipients can verify their credentials in decades, with us or without us.

  • Self-hosted option

    Enterprise plans run a hosted verifier inside your perimeter so internal teams never depend on a public endpoint.
