Abstract

Aries-VCX is a collection of Rust crates which provide APIs for stepping through Hyperledger Aries Protocols. Previously, Aries-vcx has provided it's functionality to mobile (android and ios) consumers via a wrapper layer known as libvcx. Libvcx wraps over aries_vcx functionality and creates C-callable FFI bindings, and provides Java and Objective-C bindings for calling those bindings from mobile ecosystems. Overtime, manually maintain libvcx has become quite a chore, and does not leverage new FFI tech which is now available. The goal of this mentorship project, is to create new mobile bindings using the UniFFI tool, which from initial prototyping has shown a lot promise.
