Present a Verifiable Credential

Present an AnonCreds Verifiable Credential, signed by a did:cheqd Decentralized Identifier (DID), using ACA-Py.

Using the /present-proof-2.0 API endpoints, it is possible to present Verifiable Credentials, signed by a cheqd DID, in a few clicks or lines of code. This process enables secure and trustworthy sharing of verifiable credentials within the ACA-Py framework and cheqd ecosystem.

Step 1: Create a Connection with Holder

Use any supported method to create a connection with the Holder. Automated out-of-band protocol is recommended. You can follow the same steps as described in Issue a Verifiable Credential.

Step 2: Send Proof Request

After connection is established, the Verifier can send a proof request to the Holder.
