Key points

  • Summer Mersinger will step down as Blockchain Association CEO on October 16 and remain an adviser through December.
  • Founding leader Kristin Smith will return as interim CEO on October 17 while keeping her Solana Policy Institute role.
  • The transition puts an experienced Washington policy advocate back in charge as U.S. crypto regulation remains unsettled.

Blockchain Association is changing leaders next month, with chief executive Summer Mersinger scheduled to step down on October 16 and founding leader Kristin Smith returning as interim CEO the following day. The Washington trade group announced the transition on September 25. Mersinger will remain an adviser through the end of 2026, a structure the association said is intended to support an orderly handover.

A familiar leader returns

Smith was Blockchain Association's first employee when the organization launched in 2018 and served as its chief executive until 2025. She is now president of the Solana Policy Institute and also chairs the association's board. Independent reports from CoinDesk and The Block said Smith will keep her Solana Policy Institute position while taking on the interim role, making the appointment an additional responsibility rather than a full-time departure from her current organization.

Mersinger stays through the transition

Mersinger joined Blockchain Association in June 2025 after serving as a commissioner at the Commodity Futures Trading Commission. CFTC records show her commission service ran from March 30, 2022, through May 31, 2025. The association credited her tenure with expanding its engagement with Congress and federal agencies during a period of active debate over stablecoins, market structure, tokenized securities and the division of authority between the SEC and CFTC.

Why the change matters

Trade associations do not write laws or regulations, but they shape how member companies present common positions to policymakers. A leadership change can therefore affect priorities, coalition-building and the tone of engagement with lawmakers and regulators. Smith already knows the association's membership and Washington network, which may reduce disruption while the board considers a longer-term leadership arrangement. The interim label also means the organization has not announced a permanent successor.

Policy work remains unfinished

The handover comes while the U.S. digital-asset industry is still seeking durable rules beyond agency guidance and individual enforcement decisions. The Senate recently failed to advance the Digital Asset Market Clarity Act, leaving broader market-structure legislation unresolved. That setback does not stop the SEC, CFTC or banking regulators from acting within their existing authority, but it keeps pressure on industry groups to coordinate positions across securities, commodities, payments and consumer-protection questions.

Two roles to balance

Smith's continuing role at the Solana Policy Institute creates a practical governance question that both organizations will need to manage: how she divides time and handles issues where the association's broad membership and a network-specific policy institute may have different priorities. Neither the association's announcement nor the independent reports described a conflict. The arrangement is public, and the interim status gives both organizations a clear basis for explaining responsibilities as policy debates develop.

What comes next

The confirmed timetable is straightforward: Mersinger's final day as CEO is October 16, Smith takes over on October 17, and Mersinger remains available as an adviser through December. Blockchain Association has not disclosed a search schedule or criteria for a permanent chief executive. For member companies and policymakers, the immediate signal is continuity rather than a sharp strategic break, but the lasting direction will depend on whom the board ultimately selects and how unfinished U.S. crypto legislation develops. Until then, Smith's immediate job is to maintain the association's policy work while the board determines its permanent leadership plan.
