Sphereon SSI SDK

Quickly build Verifiable Credential and SSI applications.

The Sphereon SSI SDK is an open source SDK to build SSI and Verifiable Credential applications. The SDK supports multiple DID methods, multiple VC issuance and verification methods, in a modular architecture. It exposes all methods as REST endpoints.

The SDK can run directly in React-Native (wallets) on Web and on Mobile and be used in NodeJS by agents, issuers, and verifiers.

Sphereon SSI SDK

Based on the great work done by Veramo and on the open W3C standards specifications for Decentralized Identifiers (DID) and Verifiable Credentials (VC), our SSI SDK enables you to quickly build or integrate applications that are globally interoperable and connect seamlessly with existing IAM and Business Applications, using the common OpenID Connect protocol.

  • Typescript Library
  • Multiple DID methods
  • Multiple VC issuance and verification methods
  • Modular architecture
  • Also exposes all methods as REST endpoints
  • Can be used in NodeJS by issuers, verifiers, and agents
  • Open Source (Apache 2.0)

The Sphereon SSI SDK enables you to quickly build applications to share data and documents -- peer to peer -- between parties in public administration, healthcare, finance, services, mobility, education and other industries.
