CryptoNews reports, according to PR Newswire, that Ubuntu Group has announced an expansion of its physical silver reserves held in independent third-party vaults. This additional acquisition is intended to address the increasingly tight supply in the physical silver market, and to further strengthen the underlying asset support for tokenized silver on its Ubuntu Tribe platform. Currently, all silver tokens issued by the group are fully and completely linked on a 1:1 basis to physically traceable silver bars, eliminating the use of synthetic exposure or expected inventory as issuance backing. Ubuntu Group stated that, amid the widening gap between the scale of paper futures trading and deliverable spot silver, locking in fully allocated physical inventory in advance can effectively reduce counterparty and procurement risks.
