HB 1598 proposes to establish a "Texas Strategic Bitcoin Reserve" within the state treasury. The reserve will allow Texas to acquire and manage Bitcoin as a financial asset, which the legislature identifies as having strategic potential to enhance the state's fiscal resilience, hedge against inflation, and align with innovation in digital assets. The bill outlines administration, secure storage, and management of the reserve by the state comptroller, who will develop policies and conduct audits to ensure transparency and security. Additionally, it allows for voluntary Bitcoin donations from Texas residents and enables state agencies to accept certain cryptocurrencies, which are to be converted to Bitcoin and credited to the reserve. The act includes provisions for reporting, rulemaking, and restrictions on transactions involving foreign or unauthorized entities. The subchapter governing this reserve is set to expire on September 1, 2035.
