(Bloomberg) -- The US Commodity Futures Trading Commission sued Gemini Trust Co., the crypto business run by billionaire twins Cameron and Tyler Winklevoss, claiming the company misled it in answers to questions about a futures contract pegged to the price of bitcoin on Gemini’s digital asset trading platform.

In a suit filed in Manhattan federal court Thursday, the CFTC claimed Gemini “made false and misleading statements” in meetings with commission staff from July to December 2017 about the operations of the Gemini Exchange and the Gemini Bitcoin Auction.

“The proposed Bitcoin Futures Contract was particularly significant because it was to be among the first digital asset futures contracts listed on a designated contract market, at a time of fervent interest by market participants in obtaining exposure to bitcoin through the derivatives markets,” the CFTC said.
