First Circuit Expands SEC Reach, Orders Repatriation of Offshore Crypto Proceeds

SEC Nabs Foreign Relief-Defendant in $80 Million Crypto Fraud Sweep

A federal appeals court just handed the SEC a decisive win against Raimund Gastauer, a European relief-defendant accused of holding tainted crypto proceeds. The First Circuit ruled that U.S. courts can freeze and claw back assets from non-U.S. persons who never directly sold tokens, tightening the net around anyone who touches allegedly unlawful digital-asset flows. The decision matters because it lowers the bar for regulators to reach offshore wallets and exchanges without first proving personal misconduct.

The SEC originally sued a sprawling network of entities tied to Roger Knox and the late Michael Gastauer, alleging they raised roughly $80 million through unregistered digital-token sales and then funneled proceeds through a maze of offshore companies. Raimund Gastauer, Michael’s brother living in Switzerland, was added only as a “relief-defendant”—someone who holds the money but isn’t accused of wrongdoing. After the district court ordered him to repatriate roughly $7 million sitting in Swiss accounts, he appealed, arguing the court lacked jurisdiction over a foreign national with no U.S. contacts.

Writing for the three-judge panel, Chief Judge Barron rejected that defense. The court held that in rem jurisdiction over the disputed funds is enough; Gastauer’s physical location and lack of personal ties do not shield the assets once they are traced to an alleged securities violation. Because the money allegedly originated from U.S. investors, the panel said, American courts can order its return regardless of where the nominal owner resides. The ruling keeps the freeze in place and forces Gastauer to either comply or risk contempt sanctions that could reach his other holdings.

In plain English, the First Circuit just told crypto players outside the United States that “if the money came from American investors, we can reach it—even if you never set foot in New York or sold a single token.” Relief-defendant status no longer offers the safe harbor many offshore entities assumed; merely receiving or warehousing proceeds can trigger forced repatriation without the SEC proving scienter or direct sales activity.

For markets, the decision widens the SEC’s practical authority over cross-border stablecoins, exchange wallets, and DeFi liquidity pools that touch U.S. capital. Traders and protocols that once relied on jurisdictional arbitrage now face higher compliance costs and the threat of sudden freezes, while exchanges hosting non-compliant tokens could see accelerated enforcement sweeps. Decentralized platforms may attempt to geoblock U.S. flows, but the opinion signals that any commingled asset traceable to American purchasers remains fair game.

Bottom line: offshore crypto entities just lost another layer of insulation; expect quieter balance sheets and louder lawyers until clearer global rules emerge.
