The Digital Asset Market Clarity Act — better known as the CLARITY Act — is sitting on the Senate Legislative Calendar after the Banking Committee advanced it 15-9 last month. Senator Cynthia Lummis posted on X this week that developers shouldn't need a lawyer to know if their code is legal, and that the bill is the fix. The legislation passed the House last July with a 294-134 bipartisan vote, meaning the Senate is the last big hurdle before President Biden gets a bill that could reshape how courts treat blockchain developers.
What Section 604 actually does
The core of the developer debate comes down to a single section. Section 604 codifies a principle from FinCEN's 2019 guidance: people who write and publish software — and don't take custody or control of user funds — are not money transmitters under federal law. That matters because both the SEC and the CFTC have gone after developers on increasingly creative theories. The SEC hit Uniswap Labs with a Wells Notice in 2024 claiming it ran an unregistered broker-dealer. The CFTC pursued the Ooki DAO developers, arguing that voting in open-source governance made individual contributors personally liable. The CLARITY Act would draw a bright line: no custody, no transmission.
Roman Storm's case looms large
The timing is hard to ignore. Roman Storm, co-founder of the Ethereum privacy tool Tornado Cash, was found guilty last August of conspiracy to operate an unlicensed money transmitting business. The jury deadlocked on two more serious charges — conspiracy to commit money laundering and conspiracy to violate sanctions — but the conviction he did get carries up to five years in prison. Tornado Cash is open-source, non-custodial code; Storm's defense argued that holding a developer liable for what independent users do with self-executing code sets a dangerous precedent. That's exactly the argument Section 604 would enshrine into statute for future cases.
Industry draws a line in the sand
More than 60 CEOs and founders from the biggest names in crypto — Coinbase, Uniswap, Kraken, a16z crypto, Paradigm — signed a letter to Senate leadership in June. Their message: pass the bill with developer protections intact, or don't pass it at all. They called Section 604 non-negotiable. That kind of unified industry pressure is rare, and it reflects how much uncertainty the current enforcement patchwork has created for open-source projects.
The next concrete step is a floor vote in the Senate. No date has been set yet, but the calendar is the only thing standing between the bill and the White House.
