FINANCIAL ACCOUNTABILITY STABLECOIN TRANSACTION ACT – Adds to existing law to establish the Financial Accountability Stablecoin Transaction (FAST) Act to provide for the authorization and use of payment stablecoins.

This Idaho bill establishes the Financial Accountability Stablecoin Transaction (FAST) Act to authorize the state government to use privately issued payment stablecoins for paying vendors and contractors. The legislation defines eligible stablecoins as those backed one-to-one by U.S. dollars or Treasury obligations, meeting specific criteria including at least $2 billion in annual transaction volume and being issued by U.S.-based entities with U.S. citizen founders and shareholders. The state treasurer will maintain an annual list of approved stablecoins and submit reports to the legislature on transaction volumes, cost savings, and fiscal benefits, while vendors may voluntarily choose to receive payments in these digital currencies.
