Learn how to issue and manage Verifiable Credentials and Presentations. |
Verifiable Credentials are a tamper-evident data format for asserting a set of claims about a subject. You can issue and verify Verifiable Credentials and Presentations without building complex integrations, using our simple cheqd Studio APIs.

There are many different ways to issue verifiable credentials signed by DIDs anchored on cheqd, with options for easy integration (e.g. cheqd Studio) and more bespoke integrations (e.g. Credo and Veramo). Below are a list of options for issuing credentials with cheqd underneath:
| Credo | Credo is an SDK which supports the European Architecture and Reference Framework (ARF) standards as well as AnonCreds with full cheqd support for DIDs. | credo.md |
| cheqd Studio | Our API product supports simple credential issuance in JSON and JSON-LD formats. | issue-credential.md |
| Veramo | The Veramo SDK Plugin supports JSON, JSON-LD credentials as well as cheqd Credential Payments in an SDK. | veramo-plugin |
| Walt.id Community Stack | Walt.id Community Stack is an SDK that supports the European Architecture and Reference Framework (ARF) standards for identity, with full cheqd support. | ssi-kit.md |
You can use SaaS products from our partners to create best-in-class credential ecosystems, built on cheqd
| Paradym | Paradym by Animo Solutions fully supports EU Architecture & Reference Framework standards with cheqd under the hood. | paradym-for-website.png | https://paradym.id/ |
| Cloud Platform | Cloud Platform by Walt.id similarly fully supports EU Architecture & Reference Framework standards with cheqd under the hood. | walt.id-cloud-platform.png | https://walt.id/waitlist |
Make sure you've set up your account with cheqd Studio, then you can start to:
| Issue Credentials | Issue W3C conformant Verifiable Credentials easily over REST API. | issue-credential.md |
| Verify Credentials | Verify whether Credentials are valid, have been tampered or have expired. | verify-credential.md |
| Verify Presentation | Verify whether a combination of Credentials are valid, have been tampered or have expired. | verify-presentation.md |
cheqd supports all four major digital Credential types via its selection of SDKs and APIs. Below you can learn about these Credential formats:
| SD-JWT | Selective Disclosure JWT (SD-JWT) is the most commonly adopted credential format for European Digital Identity Ecosystems, allowing users to selectively disclose which attributes they would like to share in a presentation. | |
| JSON (JWT) | JSON Web Token (JWT) Credentials are a simple way to transmit Trusted Data as a JSON object. | https://learn.cheqd.io/overview/introduction-to-decentralised-identity/what-is-a-verifiable-credential-vc/what-are-the-different-types-of-verifiable-credentials/json-jwt |
| JSON-LD | JSON-LD (Linked Data) Credentials are a richer data format, allowing applications to follow embedded links to other pieces of Linked Data across the web. | https://learn.cheqd.io/overview/introduction-to-decentralised-identity/what-is-a-verifiable-credential-vc/what-are-the-different-types-of-verifiable-credentials/json-ld |
| AnonCreds | AnonCreds is a credential format maintained by the Hyperledger Foundation, with functionality for zero knowledge proofs (ZKPs) and selective disclosure. |
Depending on what type of credentials you want to use, choose the SDK that suits your tech stack:
| Functionality | cheqd Studio | Credo (and Paradym) | Veramo | Walt.id |
