The White House expressed strong confidence that the CLARITY Act, a US crypto market structure bill, will advance as it heads toward its first Senate vote in September.

White House digital assets adviser Patrick Witt told the SALT conference in Wyoming that he is "genuinely optimistic and bullish" on the CLARITY Act, The Block reported on Aug. 18.

The Senate is in its August recess and will resume legislative business in mid-September. Senate Republican leader John Thune has set a Sept. 15 cloture vote to move the bill to formal consideration. The vote would not decide final passage, but 60 votes are needed to end debate and proceed.

Witt said the White House will meet with Democratic lawmakers and work through areas of disagreement to secure a decisive outcome in the Sept. 15 vote.

Still, key disputes remain over the more than 600-page bill. One of the main sticking points is stablecoin rewards. Sen. Angela Alsobrooks, a Democrat, and Sen. Thom Tillis, a Republican, previously reached a compromise that would bar rewards for simple holding while allowing them for transaction and payment activity.

But the issue has resurfaced. Senate Banking Committee Chairman Tim Scott said he had believed the stablecoin matter was settled, though it now needs to be discussed again, underscoring the need for further negotiations.

Another unresolved issue is a conflict-of-interest provision related to President Donald Trump's crypto business. Democrats want stronger ethics rules in the bill, citing the Trump family's expansion in crypto ventures.

Trump previously agreed to restrictions barring public officials and their spouses from directly issuing or sponsoring digital assets. Investment in digital assets would still be allowed, and the provision includes a sunset clause that expires in January 2029.

Trump is now reviewing an additional compromise proposal drafted by Sen. Ruben Gallego, a Democrat, and Tillis. The proposal would also give state attorneys general authority to enforce the ethics rules.

Sen. Cynthia Lummis, a Republican, said she could not predict Trump's final decision. She added that he had already agreed to more than any previous president.

Negotiations between Republicans and Democrats over stablecoin rewards and provisions aimed at preventing presidential conflicts of interest are set to shape the bill's fate before the Sept. 15 vote.
