The bill aims to incentivize bitcoin mining in the United States, reduce dependence on Chinese hardware, and codify the Strategic Bitcoin Reserve into law.
Republican Senators Bill Cassidy and Cynthia Lummis introduced on Monday, March 30, 2026, the “Mined in America Act”, a bill designed to strengthen domestic supply chains and formally enshrine in law the Strategic Bitcoin Reserve established by executive order under Donald Trump.
The measure establishes a federal voluntary certification program called “Mined in America”, administered by the Department of Commerce, for mining facilities and pools that meet hardware security and provenance standards. Certified operators would be required to progressively phase out devices manufactured by entities linked to foreign adversaries, with the goal of achieving full compliance by the end of the decade. “Digital asset mining is an important part of our economy. We should be doing it here in America,” Cassidy stated. Lummis added: “The Mined in America Act brings this industry back home through forward-thinking initiatives to secure our financial future.”
The context motivating the proposal is a structural imbalance: the United States controls approximately 38% of Bitcoin’s global hash rate, yet roughly 97% of specialized mining hardware is produced by Chinese companies, including Bitmain and MicroBT. Supporters of the measure argue that this dependence poses both economic and national security risks. The bill references previous incidents, including inspections of imported mining equipment and the discovery of firmware vulnerabilities that had raised concerns about potential remote access capabilities.
To bridge the production gap, the legislation tasks the National Institute of Standards and Technology and the Manufacturing Extension Partnership with supporting the development of domestically produced mining hardware. The bill does not authorize new spending, but integrates certified projects into existing federal energy and manufacturing programs. Bitcoin mining is also positioned as a grid management tool: through programs run by the Department of Energy and the Department of Agriculture, certified operators could access funding for projects that absorb excess renewable energy, stabilize grid demand, or capture methane emissions from landfills and oil fields. The industry lobbying group Satoshi Action Fund has already expressed its support for the legislation, describing it as a comprehensive policy framework linking energy policy, manufacturing, and digital asset strategy.
The most significant provision of the bill concerns the Strategic Bitcoin Reserve, which would be formally established within the Department of the Treasury. The federal government already holds a significant amount of bitcoin seized through law enforcement operations, but the reserve would provide a framework for long-term custody and accumulation. The outlined expansion pathway is described as “budget-neutral”: proceeds from staking rewards and airdrops linked to other seized digital assets would be directed toward bitcoin purchases. In addition, certified domestic miners could sell newly mined bitcoin directly to the government in exchange for a capital gains tax exemption, creating an incentive to supply the reserve at discounted prices.
If passed, the Mined in America Act would represent one of the most sweeping federal efforts ever attempted to integrate bitcoin mining into U.S. industrial and energy policy.
