Tyler Williams, a former Galaxy Digital regulatory attorney, is the key crypto adviser to President Donald Trump’s Treasury Department, putting him in the mix for a number of policy goals Trump had laid out earlier this year.
This feature is part of CoinDesk’s The list of most influential 2025.
Williams — an experienced hand in federal government circles, having worked in congressional offices and in a previous stint at the Treasury Department — was appointed 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 create a federal bitcoin reserve.
As Congress embarked on a two-pronged push into major crypto legislation — the larger effort to impose regulations on the entire crypto industry and a secondary bill to establish oversight for US stablecoin issuers — Williams was on the front lines working with the relevant congressional offices. It was the stablecoin legislation that broke through first.
“If we can put a regulatory wrapper around it in a way that allows states and bank regulators and all the ecosystems to live in the same rulebook 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 reached. The Guiding and Establishing National Innovation for US Stablecoins Act (GENIUS) Act became the law of the land, with the Treasury Department among those working to implement it.
A few weeks into the job, Williams had argued that his very existence in the department was a positive sign for the crypto sector because its needs were now a priority. And he’s had a counterpart in the White House – a crypto point person who was first Bo Hines but is now Patrick Witt, working under crypto czar David Sacks.
They are the officials directly responsible for ushering in what Trump has promised will be a “golden era” for digital assets.
