♻️Charge for Verifiable Credentials

Charge for Verifiable Credentials using encrypted DID-Linked Resources (DLRs) with Access Control Conditions, and build Verifier-pays-Issuer payment flows.

Credential Payments brings a significant evolution to the Verifiable Credentials landscape, allowing verifiers to directly pay issuers to unlock Credential Status information. Underneath the hood, we've engineered a robust and secure payment flow that streamlines the end-to-end payment process, with accuracy, speed, and cryptographic integrity.

Get started

Create encrypted Status Lists on-ledger, and pay to unlock the Access Control Conditions in CHEQ, using our cheqd Studio Payments APIs:

Charge for Status List

With Credential Payments, Issuers are able to create payment-gated Status Lists in order to charge for the verification of Credential Status information.

Issue Credential with Encrypted Status List

Issue a Verifiable Credential referencing an encrypted Status List in the body, with a specified bitstring index.

Verifier pays Issuer

Understand how a Verifier pays an Issuer in CHEQ to unlock Status List and verify Credential Status.

Bulk Update or Rotate Encryption Keys

Update a set of Credential indices or rotate the encrypted symmetric key for the Status List.
