BlockBeats News, December 17th, according to Decrypt, U.S. Senator Elizabeth Warren is issuing a warning about the national security risks that decentralized exchanges may pose, specifically calling out PancakeSwap for its reported involvement in trading of the Trump-related stablecoin USD1 and activities related to North Korean hackers stealing funds.In a letter sent this week to U.S. Treasury Secretary Janet Yellen and Attorney General Merrick Garland, Warren requested that they respond by January 12th regarding the loopholes in regulations and oversight that leave the United States vulnerable to national security threats related to DEXes, as well as what actions the agencies are taking (including regarding conflicts of interest related to the Trump family) to prevent cryptocurrency-related conflicts."You and your department bear a significant responsibility to protect the American people and the U.S. financial system," Warren wrote. "The public deserves to know whether you are investigating the serious risks identified by national security experts and the cryptocurrency industry itself."Warren cited blockchain reports from analytics firm Allium and investigation firm TRM Labs in her inquiry, which pointed out the role DEXes like PancakeSwap and DeFi tools played in the largest theft in cryptocurrency history (the $1.4 billion Bybit exchange hack in February this year). According to Allium's research, approximately 20% of the stolen funds, or $263 million, were laundered through PancakeSwap alone.In addition to North Korean cyberattacks, Warren also highlighted PancakeSwap's role in USD1 trading. In June this year, the DEX partnered with WLFI for a liquidity-driven marketing campaign to encourage trading of the USD1 pair, providing over $1 million in rewards within four weeks.Just last week, this stablecoin associated with Trump became a "core part" of Binance's infrastructure, mere months after its co-founder CZ received a pardon. Binance has denied any connection between the pardon of its former CEO and the expansion of USD1 integration. Warren had previously criticized the president's pardon of CZ and sought answers from the Justice Department regarding the company's relationship with the president."I am particularly concerned about any improper political influence by the Trump administration on law enforcement decisions," Warren wrote in this week's letter.
