A few months before the FTX crash, a group of employees discovered a backdoor in the exchange's code that allowed a subsidiary trading firm, Alameda Research, to have a negative balance of $65 billion. This is reported by the WSJ.
According to sources of the publication, the team reported the discovery to its management, who discussed the problem with one of the assistants of FTX founder Sam Bankman-Fried (SBF). The backdoor was not eliminated, and one of the managers who expressed concern was fired.
It is assumed that during the beginning of the trial over SBF, preferences for Alameda will be discussed. Among the charges, the prosecutor's office claims that the former head of FTX stole customer funds by ordering "special functions" in the software that enabled the trading firm to use the exchange as a credit fund.
According to court documents, the investigation found a deeply hidden string in the FTX code that allowed Alameda to have a negative balance. The average user's positions were eliminated automatically in this situation.
Who found the backdoor and what was behind it
In the spring of 2022, a small group of employees discovered these software features. They worked for LedgerX, a crypto derivatives trading platform that the US division of FTX acquired in August 2021.
The team was looking at ways to use the code of the main international exchange registered in the Bahamas, in the United States, where regulatory rules are much stricter.
"I just wanted to point out that there are currently several places in the [...] code base where Alameda is in one way or another enjoying special attention," the publication quotes a message from platform employee Jim Auten dated May 5.
His boss, LedgerX risk director Julie Schoening, responded that " the offshore exchange has less strict rules."
"But yes, we need to clean up these things," she added.
Previously, a specialist with a degree in physics worked for the US Futures Trading Commission, where she analyzed high-frequency trading and market manipulation.
According to the WSJ's interlocutors, the team found a number of problems in the methods of risk management and conducting liquidations, including easing for Alameda.
Schoning shared the findings with her immediate supervisor, LedgerX CEO Zach Dexter. He discussed the liquidation issue with FTX CTO Nishad Singh, who was part of SBF's inner circle. After the latter removed some of the code, Dexter considered the situation resolved.
In early August, Schoning was fired. The reason was allegedly inappropriate messages that she sent to other employees. The document with their screenshots was distributed by some FTX executives.
According to sources, the posts were forged or taken out of context. They suggest that Schoning annoyed her superiors by identifying problems with risk management.
In June, the FTX bankruptcy management team said that the company sometimes paid " informants who threatened to reveal the true fraudulent nature of the enterprise."
According to the WSJ, Schoning hired a lawyer and threatened to go to court over her dismissal. The parties allegedly agreed to settle the dispute for $5 million. However, the deal could not be completed before the exchange collapsed in November.
Singh has pleaded guilty to fraud charges and is expected to testify against SBF at the trial. Prosecutors allege that the ex-CTO knew about FTX's special relationship with Alameda and helped implement a loophole in the exchange's software.
What can Bankman-Fried admit?
SBF denies all charges. Former FTX head of institutional sales Zane Thackett, in an interview with The Block, suggested a possible line of defense for the exchange's founder on one of the main issues: whether he had illegal access to customer funds or whether mismanagement led to the collapse of the exchange.
He believes that SBF will try to "overwhelm" the jury with confusing technical details.
"I think he will argue that it was just a spot margin loan — FTX clearly allowed this practice. Then he will delve into the intricacies of how this process worked, and how Alameda was able to borrow because they had substantial collateral, throwing out big numbers like $100 billion, " said Tackett.
In his opinion, SBF can also recognize that " margin collateral systems were not as reliable as they should have been."
However, Tackett believes that these statements will face clear contradictions. The exchange operated a discount system to prevent the occurrence of risks on any particular asset.
"FTX was designed in such a way that the larger the position in a particular asset, the higher the discount of the collateral contribution or the higher the collateral requirement," the former manager explained.
According to him, it will be clear that SBF and Alameda borrowed without the margin system that worked for the rest.
"Obviously, he knew what he was doing," Thackett concluded.
During the third day of the FTX founder's trial, Adam Yedidia, a former developer of the exchange and a close friend of SBF, testified, The Block reports. He spoke about the automated system fiat@ftx.com to track FTX customer deposits. In fact, the funds were kept by Alameda in the bank account of its "daughter" North Dimension.
"I thought the firm was just holding the money," he said.
Yedidia said that at some point after playing padel tennis together with SBF, he asked if everything was all right.
"Last year we were super-reliable, this is not the case," he quoted the FTX founder as saying.
The programmer added that SBF wanted to attract additional funding from Saudi Arabia or the United Arab Emirates.
