The TrustBloc Wallet SDK repo contains APIs to receive and present W3C Verifiable Credentials(VCs) signed using W3C Decentralized Identifiers(DIDs). These APIs are useful for the holder role defined in the W3C VC Specification.
The project contains the following source code components and build scripts for SDKs.
- Go SDK
- Build native Go applications using the core pkg.
- Android and iOS SDK
- A gomobile-compatible Go SDK
- For generating gomobile-compatible bindings (see below).
- To jump straight to usage documentation, see here.
- Scripts to generate Android and iOS-compatible bindings
- Allows the Go SDK to be used in an Android or iOS app.
- A gomobile-compatible Go SDK
The repo also has code to generate a Reference iOS and Android built using the Flutter framework.
The TrustBloc Wallet SDK implements following specifications.
- W3C Verifiable Credential Data Model (VCDM)
- W3C Decentralized Identifier (DID)
- OIDF OpenID for Verifiable Credential Issuance
- Pre Authorization Code flow
- Authorization Code low
- OIDF OpenID for Verifiable Presentation
- DIF Presentation Exchange
- DIF Well Known DID Configuration

The Wallet SDK iOS xcframework packages are distributed through Swift Package Manager (SPM). Please refer
wallet-sdk tags with the suffix -swift-pm (e.g., 1.0.0-swift-pm) for the
latest releases.
The Go SDK is defined in pkg. If you want to build a native Go application, then this is what you'd use.
The gomobile-compatible version of the aforementioned Go SDK is defined in cmd/wallet-sdk-gomobile. It's similar to the Go SDK, except that the various functions, methods, and interfaces only use a subset of Go types that are compatible with the gomobile tool. The gomobile-compatible SDK generally acts as a wrapper for the Go SDK. Internally, it converts between the gomobile-compatible types and the types used by the Go SDK as needed.
