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 were linked to wallets connected to Alameda Research.

In a tweet, Bankman-Fried noted that he had no access to the transactions in question. Court papers show that a group of FTX customers outside of the United States have requested for their names to remain confidential in the insolvency case involving the company, citing the increased risk of fraud and theft in the cryptocurrency market.

The 15 creditors, who claim to be owed a combined total of $1.9 billion by FTX, are also seeking to keep the identity of those involved hidden.

FTX has voiced its concern that the personal information of its creditors could be compromised if their identities are revealed, with the top 50 creditors reportedly owed a combined $3.1 billion total.

In response, four major media outlets – The New York Times, Dow Jones, Bloomberg, and The Financial Times – have filed a lawsuit in an attempt to compel the release of the identities of those behind the breach.
