Credential Studio
A valid signature proves who signed — not that they were entitled to say it. The studio separates integrity, issuer binding, validity and status, and shows the evidence for each.

Supported: VC Data Model 2.0 and 1.1 with eddsa-jcs-2022 or ecdsa-jcs-2019 Data Integrity proofs, VC-JWT 1.1 and vc+jwt. RDF-canonicalised suites are reported as unsupported, never guessed. Status lists are fetched through the hardened egress client and verified; any failure leaves the credential indeterminate.
Results appear here: status, every check with its evidence, the proof's signed digest, issuer resolution, status-list bits and claims.
