Republican Senators Bill Cassidy and Cynthia Lummis introduced legislation Monday aimed at reshaping the U.S. digital asset mining sector, tightening supply chains, and embedding bitcoin into federal reserve strategy.
The proposal, titled the “Mined in America Act,” would establish a federal certification program for domestic crypto mining operations while phasing out reliance on foreign-manufactured hardware.
It also seeks to codify Donald Trump’s executive order creating a Strategic Bitcoin Reserve, placing the policy on statutory footing, according to a release on the matter.
“Digital asset mining is a big part of our economy. We should be doing it here in America,” Cassidy said in a statement, framing the bill as a supply chain and manufacturing initiative.
Lummis tied the legislation to a broader push to position the United States as a global hub for digital assets. “The Mined in America Act brings this industry home through forward-thinking initiatives to secure our financial future,” she said.
The bill directs the Department of Commerce to create a voluntary “Mined in America” certification for mining facilities and pools that meet security and sourcing standards. Certified operators would be required to transition away from hardware linked to foreign adversaries over a phased timeline, with the goal of full compliance by the end of the decade.
Lawmakers and industry advocates have pointed to a stark imbalance in the current mining ecosystem. While the United States controls an estimated 38% of global bitcoin hash rate, roughly 97% of specialized mining hardware is produced by Chinese firms, including Bitmain and MicroBT.
Domestic mining security push
Supporters argue that dependence poses both economic and national security risks. The bill references prior incidents, including U.S. inspections of imported mining rigs and the discovery of vulnerabilities in firmware that raised concerns about remote access capabilities.
To address the imbalance, the legislation directs the National Institute of Standards and Technology and the Manufacturing Extension Partnership to support the development of domestic mining hardware.
It stops short of authorizing new spending, instead integrating certified projects into existing federal energy and manufacturing programs.
The measure also positions bitcoin mining as a tool for grid management and energy development.
By tapping into existing Department of Energy and U.S. Department of Agriculture programs, certified operators could access financing for projects that absorb excess renewable energy, stabilize grid demand, or capture methane emissions from landfills and oil fields.
Industry group Satoshi Action Fund endorsed the legislation, calling it a comprehensive framework that links energy policy, manufacturing, and digital asset strategy.
Strategic Bitcoin Reserve gets a formal nod
Beyond industrial policy, the bill’s most significant provision may be its formalization of a Strategic Bitcoin Reserve within the Treasury Department. While the federal government already holds a large amount of bitcoin from law enforcement seizures, the reserve would establish a framework for long-term retention and accumulation.
The legislation outlines a “budget-neutral” pathway for expanding holdings. Revenue generated from staking rewards and airdrops tied to other seized digital assets would be funneled into 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 enacted, the Mined in America Act would mark one of the most expansive federal efforts to integrate bitcoin mining into U.S. industrial and energy policy.
It arrives as policymakers weigh how to balance innovation, security, and competition in a sector that has become increasingly global.
