Former FTX Director of Engineering Nishad Singh and former Chief Technology Officer Gary Wang are set to be sentenced this fall in the ongoing criminal case against what was once a global crypto exchange before it collapsed in historic fashion near the end of 2022.

Singh and Wang, who both pleaded guilty to criminal charges shortly after FTX fell apart, both testified against FTX co-founder and former CEO Sam Bankman-Fried, testifying that they were made aware of wrongdoing at the exchange shortly before it filed for bankruptcy. Another former FTX executive, Ryan Salame, was recently sentenced to 7.5 years in prison after pleading guilty to campaign finance charges. Salame did not testify against Bankman-Fried.

Singh will be sentenced on Oct. 30, in the District Court for the Southern District of New York. Wang will be sentenced a few weeks later on Nov. 20.

Another executive, former Alameda Research CEO Caroline Ellison, pleaded guilty alongside Wang, but a sentencing date has not yet been scheduled. Ellison pleaded guilty to seven criminal charges – two counts of wire fraud and five conspiracy charges – and Wang pleaded guilty to four – one count of wire fraud and three conspiracy charges.

Last February, Singh pleaded guilty to six criminal charges including fraud and conspiracy. During Bankman-Fried’s October trial, he said he discovered that there was an $8 billion hole in FTX’s finances around September 2022, but still signed off on transactions that he knew had come from customer funds.

“I learned that there was a hole that was enormous and that it had been spent and lost by Alameda, and I knew that it was $8 billion in size. So the last $8 billion of spend had necessarily come from customers. That spend included things like real estate investments, VC investments, campaign donations, and speculative events in trading,” he said.

Singh also testified that he personally programmed systems in 2019 that routed FTX customer deposits to Alameda bank accounts. In addition, he built out systems that gave Alameda “special privileges” that other FTX customers didn’t have, including the “allow negative” feature that enabled Alameda to withdraw funds in excess of its balance and collateral.

Wang, who pleaded guilty to conspiracy to commit wire fraud, conspiracy to commit securities fraud, conspiracy to commit commodities fraud and wire fraud. During Bankman-Fried’s trial, Wang said he had helped develop parts of FTX’s website. His most damaging admission may have been identifying a piece of code designed to reflect FTX’s “public insurance fund,” the public-facing figure meant to reassure investors that FTX had a reserve in case of mass withdrawals or other issues.

This figure was essentially random, and had nothing to do with what was actually in the insurance fund, Wang testified.

He told prosecutors that he cooperated with the FBI “because it seemed like the right thing to do” and to stay out of prison.

During his testimony last October, Singh similarly said he was “hoping for no jail time.”
