Blockchain analytics firm Nansen has revealed new insights into the collapse of FTX, including a $4.1 billion transfer of FTT tokens between the exchange and Alameda Research. The report highlights the close relationship between the two companies, both founded by Sam Bankman-Fried, who is now facing charges relating to FTX's collapse. Nansen analysts observed dubious on-chain interactions between FTX and Alameda before the collapse, with Alameda sending $4.1 billion FTT tokens to FTX and continuous transfers of US dollar stablecoins amounting to $388 million. The two companies controlled around 90% of the FTT token supply, allowing them to prop up each other's balance sheets.
