AUDITSubscribe to our mailing list, to participate in the public audit of Xaurum gold reserves stored at
Loomis. The reserves are stored as 1 kg and 0.5 kg bars and the status of the storage is updated daily.
Note that there should be the total gold supply (availiable from the smart contract) minus 7371 g (local storage), minus whatever the ammount Nadir has before 1 kg is reached and stored at Loomis.
The gold is prepaid as 1g 999.9 good delivery gold bars and stored as 1 kg or 0.5 kg bars, to decrease costs of storage.
