Blockchain Association Challenges Citadel Securities in SEC DeFi Debate

The Blockchain Association has formally challenged Citadel Securities regarding the regulatory framework for decentralized finance (DeFi) protocols in a letter submitted to the Securities and Exchange Commission (SEC) on Monday. The dispute centers on the SEC’s approach to innovation exemptions and how existing market structure regulations should be applied to blockchain-based financial systems.

The industry group is pushing back against arguments presented by the market-making giant, which has advocated for stricter oversight of DeFi entities. The Blockchain Association contends that current regulatory definitions, particularly those regarding what constitutes an exchange, are being misapplied in a way that could stifle technological development. By contesting Citadel's position, the association aims to influence the SEC’s policy direction, arguing that DeFi protocols operate on fundamentally different mechanics than traditional centralized trading desks.

The letter marks a significant escalation in the ongoing friction between established Wall Street firms and the burgeoning digital asset sector. As the SEC evaluates how to integrate crypto-native financial services into the broader regulatory landscape, this confrontation highlights the competing visions for the future of market infrastructure. The Blockchain Association maintains that treating decentralized protocols as traditional broker-dealers is technically infeasible and counterproductive to financial innovation. The SEC has yet to issue a formal response to the points raised in the correspondence.
