Blockchain Association sees leadership shift shortly after crypto Clarity Act fizzles
Summer Mersinger will step down as CEO of the Blockchain Association on October 16 and be replaced on an interim basis by the group's founding leader, Kristin Smith. The leadership change comes days after the U.S. Senate failed to advance the Digital Asset Market Clarity Act, a recent legislative defeat for parts of the crypto industry.

Why It Matters
The switch returns the trade group to its original leader amid a turbulent period for crypto policy in Washington, following passage of the GENIUS Act and the Senate setback on the Clarity Act. Leadership at a major industry advocacy organization could influence how the sector organizes its response to regulatory and legislative developments.
Key Facts
- Outgoing CEO: Summer Mersinger
- Interim replacement: Kristin Smith
- Transition date: October 16, 2026
- Association founded / Smith's prior tenure: Kristin Smith led the Blockchain Association from its 2018 launch until 15 months ago
- Mersinger background: Former member of the Commodity Futures Trading Commission (CFTC)
Summer Mersinger announced she will leave her role as CEO of the Blockchain Association, with Kristin Smith returning as interim chief executive beginning October 16. Smith founded and led the trade group from its start in 2018 until departing about 15 months ago; she has remained the association's board president since leaving and will keep her role as president of the Solana Policy Institute, a position she took last year.
The leadership change follows a recent legislative disappointment for parts of the crypto industry: the U.S. Senate failed to advance the Digital Asset Market Clarity Act in a vote that lacked support from all Senate Democrats and some Republicans. That setback occurred days before the association announced the transition.
Mersinger, who joined the Blockchain Association after a stint at the Commodity Futures Trading Commission, highlighted several regulatory and legislative developments during her tenure, pointing to the passage of the Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act) and increased activity at the Securities and Exchange Commission and the CFTC. In her statement, she expressed pride in the organization's progress and said she would support the group after her departure.
Kristin Smith will lead the association on an interim basis as it navigates the aftermath of the Senate vote and ongoing regulatory activity in Washington. The move returns day-to-day leadership to the organization's original chief at a moment of heightened attention on crypto policy and advocacy in the U.S.
