In the app initialization stage, subspaces can be allocated for other modules' keeper using Keeper.Subspace and are stored in Keeper.spaces. Then, those modules can have a reference to their specific parameter store through Keeper.GetSubspace.


type ExampleKeeper struct {
paramSpace paramtypes.Subspace

func (k ExampleKeeper) SetParams(ctx sdk.Context, params types.Params) {
k.paramSpace.SetParamSet(ctx, &params)
