cool, good cleanup!

This should hopefully make it a bit easier to swap out the bn128 library in the future because most of the API that a library needs to expose is contained in that substrate.rs file :)

Nice, this is something we need. We tried to integrate https://github.com/matter-labs/eip1962 behind the feature flag for std env, as it is faster, this would make this easier.

I can take a look at this -- we probably need to expose more methods to the wrapper
