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 bill establishes a framework for the State of Idaho to use payment stablecoins for government transactions, directly affecting state vendors, contractors, and the state treasurer's office. It authorizes the use of stablecoins that are qualified under the federal GENIUS Act or issued by public entities for public benefit, requiring these coins to be fully backed by U.S. dollars or Treasury obligations and meet specific operational and corporate standards. The state treasurer will maintain a public list of approved stablecoins, submit annual reports on usage and cost savings, and establish secure systems for processing payments while ensuring vendors are informed about redemption rights and risks. The legislation also allows Idaho to coordinate with other states and federal agencies on stablecoin implementation and takes effect on July 1, 2026.
