Mersinger Steps Down as Blockchain Association CEO Amid Congressional Setbacks

Summer Mersinger, former US Commodity Futures Trading Commission commissioner and CEO of the Blockchain Association, is stepping down from her role on October 16. She will leave the organization by the end of the year.

Mersinger joined the Blockchain Association in June 2025 after leaving the CFTC early, citing a desire to help the industry achieve clear rules of the road and a unified voice in Washington. Under her leadership, the group made progress on stablecoin policy, including work related to the GENIUS Act.

Kristin Smith, former CEO of the Blockchain Association, will take over as interim CEO on October 16 while continuing her position as president of the Solana Policy Institute. The organization's announcement did not mention a separate stablecoin regulatory push in the Senate that failed to advance earlier this month.
