For information on the development process for this protocol, check out sdk-development.

Implementations

• JavaScript/Typescript
• Kotlin
• Swift (only supports client-side)

Tooling

All projects (including the test vectors in this repo) use hermit to manage tooling like node, gradle, etc. Hermit version pins and automatically downloads and installs tooling for a repo, including compiler toolchains, utilities, etc. See this page to set up Hermit on your machine - make sure to download the open source build.

Test Vectors

Implementations are run against a common set of test vectors. For more information about how test vectors are used, check out the Test Vectors section of the sdk-development readme.

Example Implementations

• Example PFI in Typescript
• Example iOS Wallet in Swift

Features

A hosted set of the JSON schemas are also availbled on the hosted site.
