The Blockchain Association will change leadership in mid-October, with Chief Executive Officer Summer Mersinger stepping down on Oct. 16 and former CEO Kristin Smith returning the following day as interim chief executive. The move places one of Washington’s most established cryptocurrency policy advocates back at the helm as the industry seeks to revive federal market-structure legislation that cleared the House but stalled in the Senate.
Mersinger will remain an advisor to the association through the end of 2026, the trade group said Friday. Smith, who previously led the Blockchain Association before moving to the Solana Policy Institute, will begin her interim role on Oct. 17.
The transition gives the association a leader with deep experience in congressional advocacy at a period when the industry’s remaining legislative agenda has narrowed. Stablecoin legislation became law in July 2025, but broader rules governing the oversight and trading of digital assets remain unresolved.
Smith returns while retaining Solana Policy Institute role
Smith is currently president of the Solana Policy Institute, a policy organization associated with the Solana ecosystem. Emily Wilson, communications director for the Blockchain Association, said Smith’s position at the Solana Policy Institute will not change while she serves as the association’s interim CEO.
That arrangement links the interim leadership of a sector-wide trade group with an executive role at an organization focused on one blockchain network. The Blockchain Association represents a range of cryptocurrency and blockchain companies, while the Solana Policy Institute focuses on policy issues affecting Solana and its ecosystem.
The organizations’ work may overlap on questions that affect the entire sector, including how federal agencies classify tokens, the division of authority between regulators, and rules for trading platforms. Smith’s return also restores a familiar figure for lawmakers, congressional staff, and policy groups who dealt with the Blockchain Association during her earlier tenure.
The association did not announce a permanent successor to Mersinger or provide a timetable for naming one. Smith’s appointment gives the group continuity while it decides how to structure its leadership after a period of substantial progress on stablecoins but limited movement on the wider market-structure agenda.
Mersinger brought CFTC experience to the trade group
Mersinger joined the Blockchain Association after serving as a commissioner at the Commodity Futures Trading Commission. Former President Joe Biden nominated her for a Republican seat at the agency, and she was sworn in during March 2022.
Her regulatory experience gave the association direct familiarity with an agency that has played a central role in disputes over cryptocurrency oversight. The CFTC regulates U.S. derivatives markets and has argued for a more defined role in supervising certain digital-asset markets, particularly where tokens may be treated as commodities rather than securities.
That jurisdictional question has been at the center of industry lobbying in Washington. Cryptocurrency companies have sought legislation that would set clearer tests for when a token or transaction falls under the CFTC, the Securities and Exchange Commission, or another federal authority. Without a statutory framework, firms have faced a patchwork of agency positions, enforcement actions, and court disputes.
Mersinger’s departure does not remove her entirely from that effort because of her advisory role through 2026. Her shift away from day-to-day management nevertheless puts Smith in charge of deciding how the association approaches lawmakers and regulators during the next stage of the policy debate.
Stablecoin law marked progress, but market structure remains unresolved
During Mersinger’s tenure, Congress passed stablecoin legislation that was signed into law in July 2025. The measure delivered a long-sought federal framework for a major segment of the digital-asset market, establishing rules for stablecoin issuers and their reserves.
The association also supported the Clarity Act, a market-structure proposal that passed the House last year. The bill later stalled in the Senate, leaving its prospects for enactment this year uncertain.
The split outcome illustrates the practical challenge facing cryptocurrency trade groups. Stablecoins had a comparatively focused policy case: issuers, reserve requirements, consumer protections, and supervisory responsibilities could be addressed in a dedicated legislative package. Market-structure legislation requires agreement on more contentious questions, including token classification, exchange rules, disclosure obligations, custody, and the respective roles of the SEC and CFTC.
A House vote demonstrated that parts of Congress were willing to establish new rules for the sector. Senate inaction showed that support in one chamber does not translate automatically into a final law, particularly when a bill touches the authority and budgets of powerful federal agencies.
Lobbying strategy faces a compressed political calendar
The leadership switch comes ahead of the U.S. midterm elections, when congressional attention increasingly turns toward campaigning and party priorities. That leaves a limited window for the association and other industry groups to press for committee action, Senate negotiations, or narrower legislative compromises.
Political organizations backed by cryptocurrency companies spent heavily during the 2024 election cycle to support candidates viewed as receptive to digital-asset policy. The sector’s political spending reflected a calculation that legislation would depend on building durable support across both parties rather than relying only on agency-level engagement.
The Blockchain Association’s own federal lobbying work has focused on creating a statutory framework that reduces uncertainty over which rules apply to cryptocurrency businesses. With stablecoin legislation completed, market structure now appears to be the larger unfinished item on that agenda.
Smith’s interim appointment positions the association to pursue that objective under a leader who has previously navigated congressional negotiations and industry coalition-building. Mersinger’s continued advisory role, meanwhile, preserves access to her regulatory perspective as federal agencies continue to interpret and enforce the rules that remain in place.
