The Big Four international accounting firms have fully committed to the crypto space. Deloitte has been active in blockchain strategic consulting, Ernst & Young (EY) is deeply involved from the perspectives of crypto strategy and taxation, and KPMG has extended its reach into auditing, cybersecurity, and the entire consulting ecosystem.

This is not just a battle among the four giants. Industry experts generally believe that behind this collective increase in effort, there is a clear improvement in the US regulatory attitude. As these traditional professional service firms with significant influence enter the market one after another, it signifies that crypto assets are undergoing an important identity shift—from fringe assets gradually becoming recognized by the mainstream financial system.
