Sam Bankman-Fried, the founder of the now-defunct trading firm Alameda Research and its sister company FTX, has denied any involvement in a series of unidentified transfers and token swaps that originated from wallets associated with Alameda Research.

In a tweet, Bankman-Fried stated that he did not have access to the transfers in question.

According to court documents, a group of FTX customers outside of the United States have requested anonymity in the insolvency case involving the company, citing the increased risk of fraud and theft in the cryptocurrency market.

The 15 creditors, who claim that FTX owes them a combined total of $1.9 billion, have also requested that their identities be kept secret.

FTX has expressed concern that its creditors’ private information could be stolen if their names are made public, with the top 50 creditors reportedly owed a combined total of $3.1 billion.

In response, four major financial news outlets – The New York Times, Dow Jones, Bloomberg, and The Financial Times – have filed a lawsuit demanding that the identities of those responsible for the breach be made public.
