As of 2025, many U.S. states have their own crypto regulations with little uniformity.  However, there are two U.S. federal laws (see 
GENIUS Act and 
CLARITY Act), and Europe has its own regulations (see 
MiCA).
There is also U.S. legislation prohibiting a central bank digital currency (see 
Project Hamilton).  All digital assets in the U.S. fall under the following federal agencies.  See 
crypto glossary.
Securities and Exchange Commission (SEC)
If asset is considered a security.
Commodity Futures Trading Commission (CFTC)
If asset is considered a commodity or derivative.
Financial Crimes Enforcement Network (FinCEN)
