Am Law 100 firms Sullivan & Cromwell and Fenwick & West have removed promotional materials from their websites that stated a client relationship with FTX over the last week, a tumultuous interval that saw the cryptocurrency trading platform file for bankruptcy.

After announcing the firm advised the U.S. arm of FTX in the successful bid for a Chapter 11 acquisition of Voyager Digital in an Oct. 6 press release, Sullivan & Cromwell’s statement on that transaction could be seen on the firm’s website as late as Friday, according to a review of internet archives by The American Lawyer, but has since been removed.
