lgtm afa this PR's concerned. on a sidenote, i'd investigate if we can get rid of the *Ref providers, seems like unnecessary duplication at first glance

[gakonst]

Yeah that's what I thought as well re Ref. @rakita was there any reason?

[gakonst]

Nice thanks!

I didnt want to drop transaction after Provider is done, so I made wrapper that takes Ref.

Probably can be done with fn take(self) that would return internal transaction
