Former FTX CEO Sam Bankman-Fried has deflected a lot of the allegations leveled at him since his resignation, but today pointedly said he did not target Terra or Tether’s stablecoins.

“I made a lot of big mistakes this year. But this wasn’t one of them,” Bankman-Fried wrote on Twitter early Friday morning. “There’s no evidence, because it didn’t happen. Please, please focus on your own house.”

It was a reply to a tweet from the co-founder of defunct crypto hedge fund Three Arrows Capital Su Zhu, who said he’d been asked why he and TerraForm Labs co-founder Do Kwon have become so outspoken since FTX’s collapse at the start of November.
