What to know:

The U.S. Senate has approved the GENIUS Act with an overwhelming bipartisan vote.

This marks the first time the Senate has ever cleared a major piece of crypto legislation after years in which key Democratic members blocked the advancement of such legislation.

The bill heads to the House of Representatives, where its next steps remain uncertain while leading lawmakers work out a strategy for passage.The overwhelming bipartisan passage of the U.S. Senate's stablecoin bill, with a 68-30 final vote that saw a huge surge of Democrats joining their Republican counterparts on Tuesday, sets a new high-water mark of crypto policy efforts in the U.S. as the legislation now heads to the House of Representatives.The major Democratic backing for the Guiding and Establishing National Innovation for U.S. Stablecoins of 2025 (GENIUS) Act helps give it momentum as it lands in the other chamber, where House lawmakers can either vote on it as written or pursue changes that will require a final round in the Senate before it can head to President Donald Trump's desk.

As written, the bill would set up guardrails around the approval and supervision of U.S. issuers of stablecoins, the dollar-based tokens such as the ones backed by Circle, Ripple and Tether. Firms making these digital assets available to U.S. users would have to meet stringent reserve demands, transparency requirements, money-laundering compliance and regulatory supervision that's also likely to include new capital rules.
