Extraditions of executives from market makers Vortex, Contrarian, Gotbit and Antier mark the latest step in a multi‑agency effort targeting alleged “market‑manipulation‑as‑a‑service.”
Three crypto executives extradited from Singapore appeared in federal court in Oakland on Monday as US prosecutors expanded a wash-trading case that has now charged 10 foreign nationals tied to four crypto market-maker companies.
The court appearances mark the latest step in a US crackdown on alleged wash trading in digital asset markets that began with an undercover operation unsealed in October 2024, according to a Tuesday press release from the US Justice Department (DOJ).
The DOJ said the cases, which center on Gotbit, Vortex, Antier and Contrarian over conduct dating back to 2018, involve schemes to inflate token prices and volumes through coordinated trading that made assets appear more liquid and in-demand than they really were.
