Senators Cynthia Lummis and Bill Cassidy have introduced the bipartisan Mined in America Act to strengthen US digital asset infrastructure, according to a March 30 announcement, building on earlier efforts to position the country as a global crypto hub.

The bill codifies Donald Trump’s Strategic Bitcoin Reserve and establishes a voluntary certification framework for domestic mining operations. Under the proposal, certified facilities would be required to phase out hardware tied to foreign adversaries, while gaining access to existing federal energy and rural development programs to support the transition.

New details show the legislation is structured around reshoring the mining supply chain. It directs federal agencies to support domestic manufacturing of mining equipment, with a focus on secure and energy-efficient systems, while avoiding new spending by leveraging existing programs. The goal is to reduce reliance on foreign-produced hardware, particularly from China, which still dominates global mining equipment production.

The initiative is backed by the Satoshi Action Fund, which argues the US must align its mining capacity with domestic production. Industry data cited by the group shows the US controls a significant share of global Bitcoin hash rate, yet remains dependent on overseas hardware, creating a structural vulnerability.

The legislation also reinforces Bitcoin’s role in federal strategy by formalizing a Strategic Bitcoin Reserve within the Treasury. The move builds on prior proposals led by Lummis to establish long-term government accumulation of Bitcoin as a strategic asset.

The bill lands as Lummis approaches the end of her Senate tenure, with the lawmaker confirming she will not seek reelection in 2027. Her final legislative push has centered on integrating digital assets into US financial infrastructure, including proposals to acquire Bitcoin at the federal level and streamline crypto taxation.

Her broader tax reform efforts include exempting small crypto transactions under $300 from capital gains and taxing mining or staking rewards only when sold, measures aimed at reducing friction for everyday use while supporting industry growth.

The Mined in America Act ties these efforts together, combining industrial policy, national security, and financial strategy as US lawmakers accelerate efforts to localize crypto infrastructure and secure long-term leadership in digital assets.
