Awesome, ty for takign this on! Can we merge the SDK branch into v4? osmosis-labs/cosmos-sdk#392

(That LGTM, aside from one small comment + CI saying some go/mod update needed)

[ValarDragon]

LGTM! Lets get the SDK side merged first, to help us maintain the long term branch complexity. (Only small comment there to getting it merged :) )

Unfortunately, it wasn't in the end very small. I might try to reapproach the whole thing with @catShaark tonight, if he is at the office.
