Senators Bill Cassidy and Cynthia Lummis introduced the “Mined in America Act” to reshore U.S. bitcoin mining, reduce reliance on Chinese hardware, and codify a Strategic Bitcoin Reserve into law.
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.

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.
