Functions

func AddStakeClaim 

func AddStakeClaim(
	ctx *abciAPI.Context,

	thresholds []staking.StakeThreshold,
) error

AddStakeClaim is a convenience function for adding a single stake claim to an entity.

In case there is no errors, the added claim is automatically committed. The caller must ensure that this does not overwrite any outstanding account updates.

This method transfers the fees to the per-block fee accumulator which is persisted at the end of the block.
