bullion depository; establishment

HB 2123 establishes the Arizona Bullion Depository, managed by the state treasurer, to securely store refined gold and silver bullion (including certified coins). It creates a legal framework for an electronic payment system where Arizona residents can use bullion-backed digital transactions to buy, sell, save, or spend gold/silver as optional legal tender for private debts or state payments (if both parties agree). The bill prohibits using depository data in social credit systems and ensures deposits are fully insured. It also clarifies that exchanging bullion for other legal tender does not create tax liability.
