B-4R5-GE3, a GE3-series protocol droid, served Vogga the Hutt on Nar Shaddaa around the year 3951 BBY.
This droid's duty involved observing the transponder codes of all departing vessels from the docks. Following observation, it would relay departure details specifically concerning Vogga's freighters. Subsequently, T3-M4, Meetra Surik's droid companion, pilfered transponder codes directly from B-4R5-GE3. This theft was crucial, as it enabled G0-T0 to commandeer the Ebon Hawk.
