HB 1891 allows Oklahoma's State Treasurer to invest up to 10% of public funds (from the General Revenue, Rainy Day, and Lottery Funds) in precious metals (gold, silver, platinum) and specific digital assets with a $500 billion+ average market cap, or approved stablecoins. It requires all digital assets to be held via strict "secure custody solutions" meeting defined security standards, including encrypted key management and disaster recovery protocols. The bill also creates a new Digital Asset Property Fund to hold digital assets obtained through *criminal* asset forfeiture (excluding civil forfeiture) and return them to affected Oklahomans. This directly affects state investment policies and the management of public funds held by the Treasurer, with no impact on individual citizens' personal assets.
