Arthur Hayes, the former CEO of crypto exchange BitMEX who is currently in Singapore, is proposed to surrender to the authorities in Hawaii on April 6, according to a court filing.

Arthur Hayes has also discussed appearing remotely in New York court, said Jessica Greenwood, assistant U.S. attorney, according to a transcript of a Feb. 9 hearing. Arrangements to allow Hayes to live abroad and travel to the US for court appearances are under discussion as well. The transcript reads,

“We have discussed with counsel how to arrange for a voluntary surrender, and he has proposed appearing within the United States in Hawaii and having his initial appearance there and then, subsequent to his presentment in Hawaii, to arrange for a virtual appearance before your Honor rather than appearing in the Southern District of New York physically, that he would appear before your Honor remotely, having surrendered within the United States to the marshals.”

Another co-founder Ben Delo is planning to surrender in New York before the end of March, regarding which, the US attorney said, they are “working with the FBI and Border Patrol to obtain immigration authorization” due to complications surrounding the UK travel ban.

Greg Dwyer, who also co-founded the exchange, has declined to surrender as Greenwood said, “we were not able to negotiate a voluntary surrender with him.” As such, the US has launched extradition proceedings for him from Bermuda.

Hayes and other executives were charged with violations of the U.S. Secrecy Act last year.
