Tyler Williams, previously a regulatory lawyer at Galaxy Digital, is now the chief crypto adviser for President Donald Trump’s Treasury Department, placing him at the forefront of several policy initiatives outlined by Trump this year.

Having a wealth of experience in federal government, including roles in congressional offices and at the Treasury, Williams was appointed by Treasury Secretary Scott Bessent in February to lead a comprehensive set of crypto initiatives. The department plays a crucial role in the president’s digital assets agenda, including the establishment of a federal bitcoin reserve.
As Congress engaged in a dual effort on significant crypto legislation—aiming for broad regulations across the crypto sector and additional oversight for U.S. stablecoin issuers—Williams was actively involved with pertinent congressional offices. The legislation addressing stablecoins gained traction first.
“If we can create a regulatory framework that enables states, bank regulators, and all stakeholders to operate under the same guidelines as issuers, that’s a positive for D.C.,” he remarked at a Washington event, and later, this vision was realized. The Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS) Act became law, with the Treasury Department integral to its implementation.
Weeks into his tenure, Williams emphasized that his role within the department signaled a prioritization of crypto sector needs. He also collaborates with a counterpart at the White House—initially Bo Hines, now Patrick Witt—reporting to crypto czar David Sacks.
These officials are charged with facilitating what Trump has promised to be a “golden era” for digital assets.
