Roman Storm’s Conviction Exposes the Limits of CLARITY Act Section 604
Senator Lummis has made Section 604 of the CLARITY Act the centerpiece of her case for developer safety, citing the August 6, 2025 conviction of Tornado Cash co-founder Roman Storm as the clearest proof that open-source builders face real felony publicity below present legislation.
The provision would codify a federal secure harbor exempting non-custodial software program builders from classification as cash transmitters, a direct statutory response to the prosecution concept that put Storm in entrance of a jury.
The invoice cleared the House 294-134 in July 2025 and the Senate Banking Committee 15-9 in May 2026, however has not obtained a Senate flooring vote.
What the provision truly covers is extra particular than the business framing implies, and what it leaves intact is extra vital than its supporters are likely to acknowledge.
CLARITY Act Section 604: What the Legislative Record Actually Shows
The Digital Asset Market Clarity Act handed the House with a 294-134 bipartisan margin in July 2025, a vote rely that mirrored real cross-party help for bringing regulatory construction to crypto markets.
The Senate Banking Committee adopted in May 2026 with a 15-9 vote advancing the invoice to the full chamber. Senate floor action has remained procedurally uncertain, with no scheduled vote and energetic inter-committee friction nonetheless unresolved.
Senator Lummis has pointed explicitly to the Roman Storm case as the invoice’s animating instance. Storm, a co-founder of Tornado Cash, an open-source privateness protocol constructed on Ethereum, was convicted of conspiracy to function an unlicensed cash transmitting enterprise.
The jury deadlocked on the two extra severe fees: conspiracy to commit cash laundering and conspiracy to violate sanctions. The conviction carries a most five-year sentence.
More than 60 CEOs and founders, together with executives from Coinbase, Uniswap, Kraken, a16z crypto, and Paradigm, signed a letter to Senate management in June calling Section 604 a non-negotiable situation of their help for the broader invoice.
“Software builders shouldn’t want a military of attorneys to know if their code is authorized. The Clarity Act ends that absurdity,” Lummis mentioned. That framing captures the legislative intent. Whether the provision delivers on it relies on the particular authorized structure of Section 604 itself.
Section 604 Decoded: The Non-Custodial Developer Exemption
Section 604 is drawn immediately from the Blockchain Regulatory Certainty Act (BRCA), laws first launched in 2018 and folded into the CLARITY framework after years of reintroduction.
Its operative textual content specifies {that a} non-controlling developer or supplier shall not be handled as a cash transmitting enterprise below 31 U.S.C. § 5330, nor as engaged in cash transmitting below 18 U.S.C. § 1960, solely as a result of they publish distributed ledger software program, present self-custody instruments, or run infrastructure nodes.
The provision codifies what FinCEN’s 2019 guidance already said administratively: that non-custodial builders who by no means management consumer funds usually are not cash transmitters.
The threshold is the “non-controlling” take a look at. A developer qualifies provided that they lack the authorized proper to regulate consumer transactions, lack unilateral capability to provoke transactions on demand, and can’t effectuate transfers with out one other get together’s approval.
Non-custodial protocols, by design, meet all three situations, the good contract executes autonomously, and the developer has no key that strikes funds. Tornado Cash matches that structure exactly.
Under Section 604, the act of writing and deploying that code wouldn’t, standing alone, make Storm a cash transmitter below federal legislation.
Section 604 can also be paired with Section 601, which limits SEC registration obligations for non-custodial software program builders, and a commodities-law carve-out below Section 207, collectively making a three-part framework that treats open-source builders as technical publishers reasonably than monetary intermediaries.
That structure issues for the broader DeFi regulation panorama, not simply privateness instruments.
