Bankrupt crypto exchange FTX is seeking to claw back more than $240 million it paid for stock trading platform Embed, saying former FTX insiders did no investigation before buying the essentially worthless bug-ridden software platform.

FTX filed three lawsuits late Wednesday in U.S. Bankruptcy Court in Delaware targeting former FTX insiders including indicted founder Sam Bankman-Fried, Embed executives including founder Michael Giles, and Embed shareholders. FTX alleged that Bankman-Fried and other FTX insiders misappropriated company funds to acquire stakes in Embed as part of the transaction.
