Father of Crypto Bills, French Hill, Says Market Structure Effort Should Tweak GENIUS

Hill and Senator Cynthia Lummis agree the earlier stablecoin effort should be edited by the pending market structure bill.

What to know:

  • The finishing touch on the House of Representatives' so-called Clarity Act for U.S. crypto market structure was a section revising the stablecoin law on which the ink is barely dry, and those suggested edits may still be a factor.
  • Senator Cynthia Lummis, who is a point person on the Senate's crypto work, said she intends to respect what House lawmakers were trying to do to revise the GENIUS Act on stablecoins.
  • She and others are now shooting for an end-of-year deadline for the market structure bill in the Senate.

U.S. Representative French Hill is among his House of Representatives colleagues watching from the sidelines as their Digital Asset Market Clarity Act is overhauled by senators, but he and Senator Cynthia Lummis seem to be in agreement that one of the bill's aims should be to re-cast what Congress already did on stablecoins.

So far, the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act is the marquee accomplishment for the crypto industry and its lawmaker allies in Washington. As the new law of the land, federal regulators are already beginning work to implement its oversight of U.S. stablecoin issuers.

But that was a bill authored in the Senate after years of work in the House on similar texts, so when the House passed its Clarity Act this year on crypto market structure, it tied to that bill some changes to GENIUS. The tweaks outlined in Section 512 at the very tail end of that legislation include:

  • A more detailed section on holding CEOs and chief financial officers legally liable to routinely disclose accurate financial data, adding an annual check from an accounting firm as a backstop for the issuers' internal controls;
  • A more detailed prohibition on non-financial companies getting into the stablecoin business;
  • And assurance that a U.S. investor can "maintain a hardware wallet or software wallet for the purpose of facilitating the individual’s own lawful custody of digital assets," and can engage in peer-to-peer transactions.

"We just thought these were ways to make GENIUS stronger and better, based on work we've done in the House," Hill said in an appearance this week at CoinDesk's Policy and Regulation event in Washington.

On the sidelines of that same event, Senator Cynthia Lummis, the staunch crypto advocate who heads the Senate Banking Committee's digital assets subcommittee, said that she anticipates the Senate's eventual market structure bill will modify the young stablecoin law. She said she wants to "be very respectful of the House's amendments."

"So I do think that there will be some language that changes GENIUS," she said.

Later, at a Cato Institute event on Thursday, Hill got into the topic again, saying, "I prefer the House version, but we were able to work between the two houses to outline a few changes that we would make to GENIUS, and we put them in the Clarity Act."

The Senate Banking Committee's Republicans recently released a draft version of their bill and some senators, including Lummis, still talk about finishing their bill by the end of this month. Though its House counterpart cleared that chamber with a massive bipartisan vote — 308-122 — at least one of the Republicans on that committee, Senator John Kennedy of Louisiana, has expressed reservations about the readiness of the Senate's work.

While Hill noted that the Senate committee hasn't been working on these topics as long as the House, "I think they can get this done," he said. Work teams from both parties in the Senate are toiling away, he said, "and they are collaborating to get to yes."

The timeline now in mind for crypto advisers in the administration, including Tyler Williams at the Treasury Department, is turning the market structure effort into law by the end of this year — the target currently offered by Lummis.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

The big U.S. crypto bill is on the move. Here is what it means for everyday users

For those who don't have the compass and the time to track Congress through its arcane procedures, here's what's likely to affect you if a bill passes. Or doesn't.

What to know:

  • What's in all this congressional action for you? Potentially a fully regulated infrastructure for your crypto holdings, which could mean more safety with less outlaw vibe.
  • In the final outcome of these months (and years) of lobbying and lawmaking, crypto would become a node of the established U.S. financial system, though failure is still an option.
  • Winning the government's stamp of approval could drive more investment that raises the value of existing holdings, though rewards for investors may be under pressure in the latest negotiations.
