Most influential: Tyler Williams



Tyler Williams, a former regulatory lawyer for Galaxy Digital, is the top crypto advisor to President Donald Trump’s Treasury Department, putting him in the mix of a number of policy goals set out by Trump earlier this year.

This feature is part of CoinDesk List of the most influential of 2025.

Williams, an experienced hand in federal government circles, having worked in congressional offices and a previous stint at Treasury, was named by Treasury Secretary Scott Bessent in February to head the expanded list of crypto efforts. The department was at the center of the president’s digital asset agenda, including his call to establish a federal bitcoin reserve.

As Congress embarked on a two-pronged push toward major cryptocurrency legislation (the broader effort to institute regulations for the entire cryptocurrency industry and a secondary bill to establish oversight of U.S. stablecoin issuers), Williams was on the front lines working with relevant congressional offices. It was the stablecoin legislation that became popular first.

“If we can give you a regulatory framework that allows states, banking regulators and all ecosystems to live by the same rule book for being an issuer, I think that’s a pretty good outcome for DC,” he said at an event in Washington, and a few months later, that goal was met. The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act has become the law of the land, and the Treasury Department is among those working on its implementation.

Williams had argued within weeks of taking office that his mere existence in the department was a positive sign for the crypto sector, because its needs were now a priority. And he has had a counterpart in the White House: a key cryptocurrency person who was originally Bo Hines but is now Patrick Witt, who works under cryptocurrency czar David Sacks.

They are the officials directly responsible for ushering in what Trump has promised will be a “golden age” for digital assets.
