MATTR Pi Compact Credentials Verifier SDK

We’ve transformed our credential verification capabilities by making it work on your own mobile experience or integrating them into other types of your applications. Utilising the SDK will significantly reduce your development time while ensuring you are leveraging safe and reliable code libraries.

Interested in learning more about how you might use the MATTR Pi Compact Credential Verifier SDK? Get in touch with us today.


We wanted to make our Verifier SDK as easy to use and as flexible as possible. This allows you to start building your own verifier app or adding these core pieces of functionality to existing apps:

  • Build your own Compact Credential verification solution into existing applications.

  • Validate Compact and Compact Semantic credentials.

  • Offline verification of your trusted credentials.

  • Refresh cached revocation lists and trusted issuers.

Key Benefits

Build using the same tools as the MATTR Verifier App

The MATTR Verifier SDK allows you to take advantage of the credential verification capabilities and use them to build your own mobile verifier experiences without needing to start from scratch. You can also use the SDK to integrate credential verification functionalities into other types of applications while maintaining a consistent brand and user experience. This means you can leverage the security, privacy and trust benefits of digital identity and verifiable credentials, while significantly reducing your development time and maintaining a consistent user experience.  

Ongoing support for evolving standards  

MATTR is actively engaged in the communities that define the fast-evolving standards for digital trust and verifiable data. Our investment in updating our SDK to support these standards means that you can rely on our expertise in this space to keep your application relevant and compliant. 

Using the same codebase for iOS and Android 

We’ve built the MATTR Pi Compact Credentials Verifier SDK in React Native, which means you can create both iOS and Android apps using the same codebase. React Native is ideally suited to developing complex hybrid apps – given its advanced features and ability to provide a natural user experience. In fact, React Native took the 6th spot in the Stack Overflow Developer Survey 2021, with 14.51% of all respondent votes. 


The SDK has the following limitations: 

  • The SDK is implemented with an initial focus on developers who want to build React Native apps. 

  • The SDK provides a set of operations only, there are no UI elements provided by the SDK. 

  • Users will be given access to the NPMJS modules that contain obfuscated and minified packages.
