RAILGUN

"The Federal Bureau of Investigation (FBI) has also determined that North Korean cyber actors laundered over $60 million worth of Ethereum stolen during the Harmony heist through RAILGUN, a United Kingdom-based CVC mixer."; "According to open-source reporting, RAILGUN is headquartered in London, England."; "FinCEN assesses that RAILGUN falls under the umbrella of CVC mixing, as defined by this NPRM, because it uses its privacy protocol to manipulate the structure of the transaction to appear as being sent from the RAILGUN contract address, thus obscuring the true originator."
