TRUST & SAFETY

Verify a certificate

Every StackGrasp mastery certificate is a soulbound credential — check a token ID below to confirm it's real and unrevoked.

Try a sample: · — or enroll in a course to mint a real one.

Stronger check: confirm the holder’s identity too

Bulk verify (CSV)

Upload a CSV with one certificate ID per line (a header row is fine) to check an entire candidate pool — up to 500 IDs.

How verification works

Certificates are looked up from a real registry (GET /certificates/verify/:id) populated by course enrollment and project milestones. Chain proof (content hash, revocation, issue timestamp) is only shown when this specific holder also has a matching real on-chain credential — most certificates today are database-only and say so plainly rather than fabricate a chain check. Lookups on this page are served through a Cloudflare edge Worker that rate-limits and caches the same REST route — there is no other third-party API involved.
