DAU (道) is physical gold bullion in digital form. It represents ownership of LBMA physical kilobars of gold, which are held in independent Swiss vaults on behalf of the owner.

DAU is a digital certificate of gold ownership. Each unit of DAU you hold is digital proof that you own a physical gold kilobar stored and insured safely in independent Swiss vaults. DAU allows fractional ownership of gold, meaning there is no minimum spend to become a gold owner.
