David Hirsch, the head of the Crypto Asset and Cyber Unit in the Division of Enforcement at the U.S. Securities and Exchange Commission (SEC), has resigned after nearly nine years of service. Hirsch, who was known for his effective enforcement in the crypto space, announced his departure via a LinkedIn post. His last day at the SEC was last Friday. There is speculation that Hirsch may join a crypto company, as some reports suggest he could be moving to Solana's pumpdotfun launchpad.
