Browse Source 
* types: multiple rewards

* supply-side reward keeper methods

* remove legacy comments

* update hard claim reward to coins type

* borrow-side reward keeper methods

* update claim payout to sdk.Coins

* make tests compile

* fix genesis validation for compile

* comment out failing tests

* fix ! found logic
