Summer Mersinger will step down as CEO of the Blockchain Association, one of the cryptocurrency industry's leading advocacy organizations, with her departure taking effect on October 16, 2026. Kristin Smith, the group's founding chief executive, will return to lead the association on an interim basis while remaining president of the Solana Policy Institute, according to an official announcement from the group.

The announcement marks the second CEO change at the organization in roughly the past year and a half. News of the transition circulated on X on September 25, 2026:

A Founding Leader's Interim Return

The Blockchain Association represents companies and interests across the digital asset space and is one of the crypto industry's main advocacy groups in Washington. Mersinger's final day as CEO is October 16, after which she will remain an advisor to the organization through the end of the year.

Smith previously led the association from its founding in 2018 until about 15 months ago. She departed last year to become president of the Solana Policy Institute, a newer advocacy group focused on policy issues related to the Solana blockchain, but kept her position as board president of the Blockchain Association even after stepping down from the CEO role. She will now run both organizations at once during the interim period. A spokesman for the association confirmed that Smith will continue in her role at the Solana Policy Institute while serving as the group's interim chief executive.

Mersinger joined the Blockchain Association in June 2025, giving her a tenure at the helm of roughly 16 months. She arrived from the Commodity Futures Trading Commission, the federal regulator of the U.S. derivatives markets, where she served as a commissioner, leaving the CFTC three years before her second term was set to end and stepping into the advocacy role shortly afterward.

Timing After a Legislative Defeat

The leadership change comes about a week after a significant setback for the crypto industry in Congress. The Senate failed to advance the Digital Asset Market Clarity Act, which needed support to clear a cloture motion — the procedural step required to end debate and move toward a final vote — but did not receive enough votes from either Democrats or Republicans to move forward. Many observers now expect the legislation will not be revisited until 2027. The Blockchain Association had pushed lawmakers to support the bill throughout the process. That timeline means the incoming leadership will take the helm during an extended stretch without Senate action on the legislation the group backed.

In her departure statement, Mersinger did not mention the Clarity Act. Instead, she pointed to other achievements from her time at the organization, citing her work on the GENIUS Act, a law tied to stablecoin regulation, as well as progress on regulatory clarity at the Securities and Exchange Commission and the CFTC.

"I came here from the CFTC because I believed this industry deserved clear rules of the road and a credible, unified voice making the case for them in Washington," Mersinger said.

Smith said Mersinger led the group through what she called the most consequential period in crypto policy history. That period included the passage of the GENIUS Act, the first major U.S. crypto law.

What Comes Next

The Blockchain Association has not responded to questions about Mersinger's plans after her departure, and it remains unclear what she will do once she leaves the organization at the end of the year. Because Smith's appointment is interim, the group may search for a permanent replacement afterward. The handover is set for October 16, 2026. Developments to watch include the start of Mersinger's advisory period, how long Smith splits leadership of the two organizations, any formal move toward a permanent CEO search, and whether the Senate takes up the Clarity Act in 2027 as observers anticipate.
