FTX used Python code to fake its insurance fund figure: Gary Wang

FTX’s so-called “Backstop Fund” figure was a big lie, according to the former chief technology officer of the crypto exchange

Crypto exchange FTX used hidden Python code to misrepresent the value of its insurance fund — a pool of funds meant to prevent user losses during huge liquidation events — according to testimony from FTX co-founder Gary Wang. 

In a damning new testimony on Oct. 6, FTX's former chief technology officer, Gary Wang, said that FTX’s so-called $100 million insurance fund in 2021 was actually fabricated, and also never actually contained any of the exchanges’ FTX tokens (FTT) as claimed.

Instead, the figure shown to the public was calculated by multiplying the daily trading volume of the FTX Token by a random number close to 7,500.

When the prosecution surfaced the above tweet — among other public statements of its value — and asked Wang whether this amount was accurate he replied with a single word: “No.”

“For one, there is no FTT in the insurance fund. It's just the USD number. And, two, the number listed here does not match what was in the database.”

An exhibit in the Oct. 6 trial shows the alleged code used to generate the size of the so-called "Backstop Fund” or public insurance fund. 

FTX's insurance fund was designed to protect user losses in case of huge, sudden market movements and its value was often touted on its website and social media.

According to Wang’s testimony, however, the amount contained within the fund was often insufficient to cover these losses.

For example, in 2021, a trader was able to exploit a bug in FTX's margin system to take an outsized position in MobileCoin, which resulted in a loss to the tune of hundreds of millions dollars for FTX, according to Wang.

When Bankman-Fried realized that the insurance fund had all but been exhausted, Wang said he was told to make Alameda “take on” the loss. This was supposedly in an attempt to hide the loss, as Alameda’s balance sheets were more private than those of FTX.

In addition to revealing the allegedly fraudulent nature of FTX’s insurance fund, Wang claimed that he and Nishad Singh were prompted by Bankman-Fried to implement an “allow_negative” balance feature in the code at FTX, which allowed Alameda Research to trade with near-unlimited liquidity on the crypto exchange.

On Oct. 5 Wang — who has already pleaded guilty to all charges pressed against him — admitted to committing wire fraud, commodities fraud and securities fraud with Bankman-Fried, former Alameda Research CEO Caroline Ellison and former-FTX director of engineering Nishad Singh.

Breaking: Caroline Ellison and Gary Wang plead guilty to fraud charges

Both former executives of FTX and Alameda Research have been charged for their role in the "frauds" that led to FTX's collapse.

Former Alameda Research CEO Caroline Ellison and FTX co-founder Gary Wang have pleaded guilty to federal fraud charges and are cooperating with prosecutors as part of the criminal case against the former CEO of FTX, Sam Bankman-Fried.

United States Attorney for the Southern District of New York (SDNY), Damian Williams made the announcement on Dec. 22, emphasizing that the latest major development is unlikely to be the last.

"As I said last week, this investigation is ongoing and moving very quickly. I also said last week's announcement would not be our last and let me be clear once again, neither is today's," he said, adding that:

I'm announcing that SDNY has filed charges against Caroline Ellison [...] and Gary Wang [...] in connection with their roles in the frauds that contributed to FTX's collapse. Both Ms. Ellison and Mr. Wang have plead guilty to those charges and both are cooperating with the SDNY. 

Williams also confirmed that SBF is now in the custody of the Federal Bureau of Investigation (FBI) and is "on his way back to the United States" where he will be transported directly to the Southern District of New York to appear before a judge "as soon as possible."

Williams also used the statement to send a stark warning to anyone that may have participated in misconduct at FTX or Alameda:

"Now is the time to get ahead of it. We are moving quickly and our patience is not eternal."

SBF was officially handed over from Bahamanian custody to U.S. authorities on Dec. 21 after he waived his right to a formal extradition process that could have taken weeks. His lawyer claimed that SBF wanted to speed up the process as he is currently driven to "put the customers right."

Meanwhile, Ellison's recent guilty plea and cooperation with the SDNY may be unsurprising for some, given that she was reportedly spotted at a coffee shop just a short walk away from the U.S. Attorney’s Office and the New York FBI office on Dec. 5.
