ESSI Studio · Credential management
ESSI Studio is our credential management system: define schemas, issue and revoke credentials, and see the state of every issuance from one place. It was contributed to the Open Wallet Foundation as Apostille.
Issuance
Define a schema once, then issue against it — single credentials or batches.
Revocation
Revoke without contacting the holder, and let verifiers check status privately.
Key custody
Issuer keys stay under your control, with rotation and recovery paths defined up front.
Interoperable
W3C DIDs, verifiable credentials and AnonCreds, so wallets you do not control still work.
Open source — Apostille, in OWF Labs
ESSI Studio is open source. It was contributed to the Open Wallet Foundation as Apostille and lives in OWF Labs, so the credential layer is governed in the open rather than by a single vendor.
