Fifth Circuit Narrows SEC’s Crypto Reach, Preserves Aiding‑And‑Abetting Liability

COURT HANDS SEC PARTIAL VICTORY ON CRYPTO JURISDICTION

The Fifth Circuit just narrowed the SEC’s reach over crypto platforms that merely route orders to offshore exchanges, yet left the agency’s core enforcement power intact. The April 17, 2025 ruling in case 23-11237 simultaneously limits and legitimizes SEC authority, ensuring both regulators and traders will litigate the gray zones for years.

The appeal grew out of an SEC enforcement action against a U.S.-based order-routing service that funneled customer trades to a foreign crypto exchange. The lower court sided with the agency, but the platform argued it was not itself operating an exchange and therefore fell outside federal securities law. A three-judge panel had to decide whether routing alone equals “operating a national securities exchange” under the Securities Exchange Act of 1934.

The Fifth Circuit held that the routing service is not an exchange and therefore escapes direct registration requirements. At the same time, the court affirmed that the SEC can still pursue the firm for aiding and abetting violations if it knowingly funnels U.S. customers to an unregistered exchange. Judges stressed that intent and knowledge, not the routing mechanics themselves, determine liability.

In plain English, the decision tells the SEC it cannot label every intermediary an exchange, but it can still police U.S. actors who deliberately link American traders to offshore venues that ignore U.S. rules. Platforms gain breathing room to design routing tools, yet they inherit legal risk if they ignore red flags about their foreign partners.

For markets, the ruling shifts authority toward case-by-case enforcement rather than blanket registration mandates, easing some compliance costs for U.S. software providers while keeping the threat of aiding-and-abetting suits alive. Decentralized protocols that merely list smart-contract addresses sit on firmer ground, but stablecoin issuers and centralized exchanges that court U.S. liquidity remain squarely in the crosshairs. Traders see slightly lower legal friction for offshore routing services, yet they still face the reality that counterparties can be dragged into U.S. courts.

The safe play now is to document every onboarding check; the expensive mistake is to assume that geography alone will keep the SEC at bay.
