Contributions

Contributions are very welcome! If you have questions or issues, please let us know on Discord or at our bi-weekly community call.

Install

Install Rust: https://www.rust-lang.org/tools/install

We recommend using rustup, as VCX is currently tied to Rust v1.79.x (this maintains consistency between local and CI environments).

Anoncreds and Indy require the use of openssl and zmq. These may be vendored by consuming applications, but for development installation is required.

Note

For those familiar with the Indy SDK dependencies (which is no longer in use as it has been replaced by anoncreds-rs, indy-vdr, and aries-askar) note that:

• Openssl requirements are no longer restricted to the out of support 1.1 version.
• Libsodium is no longer required (as it's been replaced by anoncreds-clsignatures)

Linux / MacOS:

• ZMQ: https://zeromq.org/download/
• Openssl: https://docs.rs/openssl/latest/openssl/#automatic

Windows

If you get a VCX development environment running in Windows, we'd love a contribution documenting that process here!
