Crypto’s Biggest Regulatory Fight Is About Who Controls DeFi

For years, Washington’s crypto debate revolved around one question: what exactly are digital assets? In 2026, that argument is finally becoming less important. Crypto’s biggest regulatory fight is shifting somewhere harder — toward decentralized finance and the question of who, if anyone, actually controls the software moving billions of dollars without a traditional intermediary.

The latest version of the CLARITY Act makes that shift explicit. Released on September 10, the 630-page Senate draft creates rules for what it calls “non-decentralized finance trading protocols.” Instead of simply asking whether a project calls itself DeFi, regulators would examine whether a person or coordinated group still has the power to control or materially alter how the protocol works.

Why Bitcoin Is No Longer the Main Regulatory Problem

Bitcoin was once the perfect target for regulatory uncertainty.

Was it a security? Could exchanges legally sell it? Could institutions hold it? Would regulators eventually try to push it outside the financial system?

Most of those questions are now much easier to answer.

Bitcoin trades through regulated U.S. investment products, including spot ETFs. The SEC and CFTC have also moved toward a clearer digital-asset framework, with their March 2026 joint interpretation explicitly recognizing categories of crypto assets that are not securities.
