Turn audits, certifications, and business assurances into signed public records that any person—or system—can verify.
What is being attested
Every trust signal resolves to inspectable proof.
Credential model
W3C VC 2.0Open, portable records
Digital signature
Ed25519Issuer-authenticated proof
Record integrity
SHA-256Tamper-evident history
Availability
Public APIHuman and machine readable
Certis makes the complete chain visible: who made the claim, what was attested, how it was signed, and whether it remains valid now.
Start with the public record—not a marketing badge. A single code resolves the subject, issuer, status, dates, claims, and current cryptographic result.
Registry resolution · ACME2025
Read the assurance as a precise credential. Claims remain attached to their issuer, subject, issuance date, validity window, and immutable identifier.

Follow the provenance from the issuing organization to the signed credential, the recipient who claimed it, and every subsequent verification event.
Provenance chain
Create the same verifiable record through a focused dashboard or API. The recipient gets portable evidence; every verifier gets the canonical public source.
Issuer interface
Certis does not ask verifiers to trust a visual mark. The credential, public key, canonical payload, and signature are available for independent validation.
