Hayden Adams, the founder of Uniswap, has criticized Citadel Securities for urging the US Securities and Exchange Commission (SEC) to treat decentralized finance (DeFi) protocols like traditional financial intermediaries. This move by Citadel has sparked a backlash from Adams and others in the DeFi community. They argue that DeFi’s open-source nature should not be compared to centralized financial systems.

Citadel Urges SEC to Regulate DeFi Like Traditional Finance

Citadel’s push to the SEC suggests that DeFi protocols and their developers should be treated as intermediaries in the same way as traditional financial institutions. The firm has specifically called for a technology-neutral approach in regulating markets, meaning that activities in DeFi should not receive lighter treatment just because they use blockchain technology. In a lengthy letter to the SEC, Citadel argues that many decentralized systems, such as those for tokenized equities, function similarly to exchanges or broker-dealers.

The firm also points to the roles of developers, validators, and liquidity providers in DeFi. According to Citadel, these players take transaction-based fees or influence the routing of orders, making them comparable to regulated intermediaries in traditional finance. Citadel’s filing further claims that DeFi’s ability to provide “fair access” to markets is questionable, a point that Adams strongly disagreed with.

Hayden Adams Responds to Citadel’s Push

Hayden Adams took to X to express his opposition to Citadel’s stance. He criticized Citadel for trying to apply traditional financial regulations to decentralized protocols. Adams linked Citadel’s latest actions to its earlier involvement in blocking the ConstitutionDAO project in 2021, where Citadel’s founder, Ken Griffin, outbid the group for a rare copy of the US Constitution.

Adams’ post pointed out the irony in Citadel’s claim that DeFi cannot ensure fair market access. “Makes sense the king of shady tradfi market makers doesn’t like open source, peer-to-peer tech that can lower the barrier to liquidity creation,” Adams wrote. His sharp response reflects broader concerns that regulations meant for centralized entities may stifle the innovation that DeFi brings to the financial landscape.

DeFi Community Concerned About Potential Regulatory Overreach

Adams and other DeFi advocates worry that the SEC’s acceptance of Citadel’s framework could subject decentralized protocols to strict regulations. Such regulations could require registration, capital rules, and compliance with best execution duties designed for traditional broker-dealers. Many in the DeFi community believe that these measures would be incompatible with the open-source, permissionless nature of decentralized finance.

In their view, the SEC’s application of traditional finance regulations to DeFi could lead to a fragmentation of the space. The decentralized ethos of DeFi protocols, which enable small teams and distributed communities to operate, would be at risk. The push from Citadel is seen as an effort to centralize a space that was designed to be open and accessible to anyone.

A major focus of Citadel’s letter to the SEC revolves around tokenized equities. The firm argues that allowing tokenized shares of US companies to trade on DeFi platforms could create a “shadow equity market” outside the current regulatory framework. Citadel warns that such a move could undermine the investor protection mechanisms in place for traditional equities.

The firm also pushes back against calls from some in the crypto community for broader exemptions for DeFi. Some DeFi advocates argue that open-source protocols should not be subject to the same rules as traditional exchanges or broker-dealers. Citadel counters that allowing exceptions for DeFi could weaken the regulatory framework governing tokenized equities.
