Mae'r cyllid diweddaraf yn cael ei gysylltu â'r system ardrethi annomestig, a bydd yn ychwanegu at y Gronfa i Fusnesau dan Gyfyngiadau a roddwyd ar waith ddechrau mis Rhagfyr.
The latest funding is linked to the non-domestic rates system and will operate as a top up to the Restrictions Business Fund which was put in place in early December.
