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, known as the FAST Act, authorizes the State of Idaho to use payment stablecoins for making payments to vendors and contractors. It establishes a list of approved stablecoins that must meet specific federal standards under the GENIUS Act, including being fully backed by U.S. dollars or treasury obligations and issued by U.S.-based entities with transparent reserve reporting. The state treasurer will maintain this list annually and report to the legislature on how stablecoin usage provides fiscal benefits, while vendors can choose but are not required to accept these digital payments. The bill also allows Idaho to coordinate with other states on stablecoin policies and requires secure systems for handling these transactions.
