Senators Cynthia Lummis and Ron Wyden have proposed the bipartisan Blockchain Regulatory Certainty Act to exempt non-custodial blockchain developers from federal money transmitter laws. The bill aims to protect developers who maintain code and infrastructure without controlling user funds, preventing them from being regulated like banks. This legislation seeks to provide regulatory clarity, harmonize federal and state laws, and counteract legal challenges faced by developers such as those in the Tornado Cash and Samourai Wallet cases.
