The Blockchain Association, one of Washington’s most prominent digital-asset advocacy groups, is preparing for a leadership change. Current chief executive Summer Mersinger will leave the role on October 16, 2026. Founding leader Kristin Smith is expected to return the next day as interim CEO while the board looks for a permanent successor.
Mersinger will stay on as an adviser through the end of the year to help manage the handover.
The timing is notable. The announcement came only days after the Senate failed to advance the Digital Asset Market CLARITY Act, the industry’s main market-structure bill, on a 49-50 cloture vote.
That setback followed months of lobbying after the House had already passed the measure.
The group has not framed the departure as a direct consequence of the vote, but the sequence has drawn attention across crypto policy circles.
Mersinger joined the association in June 2025 after serving as a Commodity Futures Trading Commission (CFTC) commissioner.
She brought Hill experience, including senior work for Senate Majority Leader John Thune, and a regulator’s résumé.
During her roughly 16 months in the job, Congress enacted the GENIUS Act, a federal framework for payment stablecoins signed into law in July 2025.
The association also reported heavier engagement with lawmakers and agencies, including more than 300 meetings in 2026 and multiple member fly-ins on Capitol Hill.
Supporters credit her with giving the industry a more established voice at a moment when both legislation and agency guidance were moving quickly.
Smith’s return is a homecoming.
She was the association’s first employee when it launched in 2018 and served as CEO until 2025, building the organization from a one-person shop into a membership group representing more than 100 companies and projects.
She left last year to become president of the Solana Policy Institute and has remained board president of the Blockchain Association.
Officials at the Solana Policy Institute say that role is unchanged; she will add the interim Blockchain Association post beginning October 17.
Smith has described the assignment as personal, saying Mersinger took the helm at a consequential moment for crypto policy and met it.
Mersinger, in turn, has said Smith built the association from the ground up and that the group is in good hands.
The arrangement is explicitly temporary.
The board is expected to search for a lasting chief executive while Smith steadies operations, keeps advocacy campaigns moving, and maintains relationships with members and policymakers.
The association has said its policy priorities are not changing.
Those priorities still include market-structure rules, stablecoin implementation, and clearer lines between the SEC and CFTC after years of uncertainty over how digital assets should be classified.For an industry that has spent the past two years oscillating between landmark wins and legislative stalls, continuity at the top of its main trade group matters.
Smith knows the membership, the Hill relationships, and the organization’s history.
Mersinger’s remaining months as an adviser are meant to reduce disruption. Whether the interim period is brief or extended will depend on how quickly the board identifies a permanent leader and how the next Congress treats unfinished digital asset legislation.
The episode also illustrates how tightly crypto advocacy in Washington is tied to the legislative calendar.
A year that produced a signed stablecoin law and record outreach still ended with a high-profile Senate defeat and a change at the top of the industry’s leading association. Smith now steps back into the organization she founded to guide it through the next chapter.
