US Crypto Clarity Act Amendment Raises DeFi Regulatory Concerns

Senate Committee Revision Adds Risk for DeFi Developers

A last-minute amendment to the US Digital Asset Market Clarity Act has raised concerns across the decentralized finance sector after changes were introduced during a Senate Banking Committee markup. The bill, which advanced with a narrow 15–9 bipartisan vote, originally included protections shielding non-controlling blockchain developers from being classified as money services businesses. However, the revised language could still allow regulators to treat some developers as securities intermediaries if they are found to have influence over protocols.

“Arrangement or Understanding” Clause Expands Oversight Scope

The updated bill language allows regulators, including the Securities and Exchange Commission, to examine whether individuals are acting under an “agreement, arrangement, or understanding” that could imply control over a decentralized protocol. Critics warn this could widen regulatory reach beyond genuinely centralized platforms, potentially capturing developers, governance token holders, and contributors who do not directly manage user funds. While the Blockchain Regulatory Certainty Act protections for software developers remain intact, the broader ambiguity is raising uncertainty.

Bipartisan Progress Continues Despite Industry Debate

Senators Angela Alsobrooks and Ruben Gallego supported the revised bill, helping it move forward, while Senator Mark Warner signaled possible future support. Lawmakers described ongoing negotiations covering stablecoins, consumer protection, and crypto ATMs. The bill now moves toward further Senate review and potential merger with related legislation before a final vote.
