US lawmakers propose amendment to crypto market structure bill before markup

Two bills in the US Congress considering stablecoins and a digital asset regulatory framework will reach crucial stages this week after long debates and controversies.
US lawmakers on the House Financial Services Committee are expected to meet for a markup hearing on Tuesday to consider a cryptocurrency market structure bill, which could be amended to add protections for blockchain developers.
According to a notice released ahead of the hearing, committee chair French Hill introduced an amendment to the Digital Asset Market Clarity Act of 2025, otherwise known as the CLARITY Act, focusing on the “treatment of certain non-controlling blockchain developers.” The amendment proposed that, under the potential market structure law, certain blockchain developers or service providers would not be considered money transmitters or subject to their registration requirements.
The provision for blockchain developers appeared to originate from the Blockchain Regulatory Certainty Act, legislation spearheaded by Representative Tom Emmer and a bipartisan group of lawmakers in May. Many crypto advocacy groups, including the Blockchain Association, called on lawmakers to combine the two bills.
