==Abstract==
Although Ethereum allows developers to create absolutely any kind of application without restriction to specific feature types, and prides itself on its "lack of features", there is nevertheless a need to standardize certain very common use cases in order to allow users and applications to more easily interact with each other. This includes sending currency units.
