Sam Bankman-Fried’s crypto empire filed for Chapter 11 bankruptcy in Delaware, capping rapid downfall for the companies. 

Entities tied to, FTX US and trading firm Alameda Research Ltd. were part of the filings, according to a Twitter statement Friday. Chapter 11 bankruptcy lets a company continue operating while it works out a plan to repay creditors. 

Bankman-Fried resigned as chief executive officer as part of the filings, and John J. Ray III was appointed to replace him, the statement said. 

Crisis quickly befell FTX  this month after prices for the exchange’s native crypto token, FTT, plummeted and users raced to withdraw their assets. Rival crypto exchange leader Changpeng “CZ” Zhao had earlier said he would sell some US$529 million of FTT coins due to “recent revelations that came to light.”

Zhao’s Binance Holdings tentatively agreed to buy amid the exchange’s liquidity crunch, but backed out of the deal following a short period of due diligence.
