Buried on page 230 of the CLARITY Act is arguably the biggest win for the digital asset industry in the entire 309-page bill.

Section 604: The Blockchain Regulatory Certainty Act.

If you build open-source blockchain software and don't have unilateral control over users' funds, you are not a money transmitter. Not under FinCEN rules. Not under federal criminal law. Not under state registration requirements.

Writing code ≠ money transmission.

Building self-custody tools ≠ money transmission.

Running node infrastructure ≠ money transmission.

For years, developers have operated under the threat that publishing code could expose them to money transmission charges. Section 604 eliminates that ambiguity entirely. It establishes a clear, codified legal protection for the people who actually build the open-source infrastructure this industry runs on.
