Problem

At the moment the Rust SDK does not work with WASM, nor do protobufs. It'd be great if we could compile and utilize the SDK in a WASM environment. At a minimum, if protobufs could compile properly, that would enable us to have WASM code that generates proper transaction bytes that a JavaScript client could utilize. This unlocks a number of important use-cases.

I believe the crux of the issue is related to tonic which depends on mio. mio does not appear to compile for WASM, returning errors like these at build time

639 |         self.inner.deregister(registry)
    |                    ^^^^^^^^^^ method not found in `IoSource<UdpSocket>`
    |

Solution

• Remove tonic as a dependency and find another alternative to build the proto files.
• Add unit tests in a WASM environment
