Second Circuit: Crypto Platforms Can Be Brokers Even Without Custody

SEC WIN IN SECOND CIRCUIT REWRITES EXCHANGE LIABILITY

The Second Circuit just gave the SEC its clearest win yet against crypto exchanges that claim they only provide “access,” not trading services. The court ruled that platforms facilitating token sales can be held liable as unregistered broker-dealers even when they never take custody of customer funds. The decision lands while the Commission’s enforcement campaign is under fresh political pressure and could reshape how every major venue structures its operations.

The lawsuit began when the SEC sued a New-York-based trading platform that allowed users to buy and sell more than thirty tokens the agency calls unregistered securities. The platform argued it was merely a “software provider” because trades settled peer-to-peer and assets never touched company wallets. A district judge agreed and dismissed the case, but the three-judge panel reversed in a unanimous opinion that focused on economic reality over code architecture.

Writing for the court, Judge Livingston said the Exchange Act covers any person who “effects transactions” for others, not just those holding keys. The panel rejected the platform’s decentralization defense, noting that its order-matching engine, fee schedule, and customer-support function gave traders a single point of contact—the very hallmarks of a broker. The judges also refused to carve out an exemption for “software” that performs exactly the same service as a traditional broker.

In plain terms, the ruling means any interface that pairs buyers and sellers, sets fees, or provides settlement instructions can be deemed a broker, regardless of where the tokens actually sit. That standard will travel quickly: the Second Circuit hears most major securities cases, and its reasoning is already being cited in pending actions against other venues.

For markets, the decision tightens the vise on offshore and “decentralized” exchanges that still route U.S. traffic. It raises the cost of regulatory avoidance, increases pressure on issuers to register tokens, and hands the SEC a stronger hand in settlement talks. Stablecoin issuers that rely on exchanges for distribution now face added compliance risk, while traders should expect thinner liquidity on smaller tokens if platforms delist to reduce exposure.

The message is simple: if your code acts like a broker, the law will treat it like one.
