Citadel Securities urges SEC to classify some DeFi protocols as regulated exchanges or broker-dealers, drawing criticism from Hayden Adams and crypto advocates defending open-source, permissionless systems.
Citadel Securities submitted a Dec. 2 letter to the SEC warning that certain DeFi protocols handling tokenized U.S. equities may function like regulated exchanges or broker-dealers because they match buyers and sellers via smart contracts. The firm urged that any exemptions follow formal rulemaking to avoid inconsistent oversight between tokenized and traditional markets. Uniswap’s Hayden Adams and other crypto commentators condemned the letter, arguing it misrepresented open-source developers as intermediaries and resisted decentralized participation. The dispute reflects ongoing tensions between traditional finance favoring strict regulation and DeFi proponents advocating for minimal intermediary oversight.
