US Senators Cynthia Lummis and Ron Wyden propose the Blockchain Regulatory Certainty Act (BRCA) to exempt blockchain developers and service providers who do not handle user funds from money transmitter regulations. The bill aims to clarify that writing code or maintaining blockchain networks should not trigger federal or state money-transfer requirements, addressing developer concerns over potential criminal liability. The legislation has garnered support from crypto industry groups but still faces uncertain progress through Senate committee markups.
