Gary Wang, FTX's co-founder and former CTO, testified in court about the connections between the crypto exchange and Alameda Research. Wang claimed that Alameda's account on FTX was the only one authorized to trade more than it had available, a feature called "allow negative." He also stated that former CEO Sam Bankman-Fried had given Alameda a $65-billion line of credit despite contrary public statements. The prosecution alleges Bankman-Fried used FTX user funds at Alameda without consent. Wang has already pleaded guilty to fraud charges, and the trial is expected to continue through November.
