Crypto lobby and sheriffs' group trade letters over Clarity Act's DeFi carve-out, with days left before recess

The Blockchain Association sent a letter to Senate Majority Leader John Thune and Minority Leader Chuck Schumer on Monday arguing that the National Sheriffs' Association had misread how the Clarity Act treats decentralized finance, according to The Block, which reviewed the letter and interviewed the group's chief policy officer, Lindsay Fraser.

The dispute is over timing as much as substance. The Senate leaves Friday for August recess, and after that, attention turns to November's elections — a narrow window for the bill, which would be the first comprehensive federal framework for the crypto industry. Thune has not set a date for the procedural vote that must precede any vote to advance the bill, but told Bloomberg on Monday he still expects it before the recess, The Block reported.

The sheriffs' association — which says it represents more than 3,000 sheriffs and 10,000 public safety officials — wrote to the same two leaders last week warning that the bill's carve-outs around anti-money-laundering, sanctions and know-your-customer obligations are too broad, and that no one in the industry should receive a "blanket exemption." Its specific target is Section 10604, the Blockchain Regulatory Certainty Act, which creates a safe harbor establishing that non-custodial developers are not money transmitters. The sheriffs asked for it to be deleted or narrowed.

The Blockchain Association's response, per The Block: the bill imposes "rigorous obligations" on intermediaries, preserves a line between "financial intermediation and neutral software development," and would not let operators who actually control a protocol escape rules by calling themselves decentralized — the bill directs the SEC to write rules on that point. The group also cited a letter last month from 160 former law enforcement and national intelligence officials backing the bill, saying that record "forecloses any suggestion that NSA's interpretation reflects the consensus of the law enforcement community."

Key facts

• Blockchain Association letter to Thune and Schumer, sent Monday, Aug. 3 (The Block).
• NSA letter sent last week; group claims 3,000+ sheriffs, 10,000+ public safety officials (The Block, citing the letter).
• Contested provision: Section 10604, Blockchain Regulatory Certainty Act — safe harbor for non-custodial developers (The Block).
• 160 former law enforcement and intelligence officials signed a pro-Clarity letter last month (The Block, citing the Blockchain Association).
• Senate recess begins Friday; no procedural vote scheduled as of Monday afternoon (The Block, citing Thune via Bloomberg).

The real-world read

Neither letter is public here — both sides' characterizations come through a single outlet, and the Blockchain Association is a paid industry lobby whose members benefit directly from Section 10604. Its "correcting the record" framing is advocacy, not neutral analysis, and Fraser said the quiet part herself: the letter exists to clear the decks "so that when an ethics deal is reached, we're ready to hit the floor."

That ethics deal is the actual blocker, and the industry letter says nothing about it. Democrats want language addressing President Trump's crypto holdings — the memecoin launched before Inauguration Day and his family's stake in World Liberty Financial, which financial disclosures last month tied to millions of dollars in payments to him. Bipartisan text went to the White House last week; no agreement as of Monday. Note also that The Block's own account slips between "BA" and "BSA" when describing who pushed back — a small thing, but the letters themselves remain unpublished.

Opinion, and whose

• Fraser (Blockchain Association): a floor vote is near, so misconceptions must be corrected now; the bill supports law enforcement.
• NSA: the carve-outs would leave DeFi outside AML, sanctions and KYC obligations.
• Thune: still expects a procedural vote before Friday — a forecast, not a scheduled event.
