Sam Bankman-Fried's old penthouse roommate insisted on immunity before testifying because he feared he unwittingly facilitated a crime

• Sam Bankman-Fried's ex-confidant Adam Yedidia testified Wednesday at the FTX cofounder's trial.
• Yedidia insisted on immunity to testify because he was worried he may have facilitated a crime.
• He roomed with SBF at a $35 million Bahamas penthouse and worked at both FTX and Alameda.

Before Adam Yedidia could testify against Sam Bankman-Fried at the FTX cofounder's criminal trial, he needed reassurances.

In federal court in downtown Manhattan on Wednesday, Yedidia told jurors that he insisted on getting immunity from future prosecution in order to testify about his experience working for the now-collapsed cryptocurrency trading platform FTX, where he was a software developer.

"I was concerned that as a developer at FTX I may have unwittingly written code that contributed to the commission of a crime," Yedidia said on the witness stand.
