U.S. Senator Elizabeth Warren, a vocal opponent of cryptocurrencies, sent a letter to Meta CEO Mark Zuckerberg demanding an explanation regarding the company's stablecoin adoption plans. Senator Warren stated, "I request answers to seven items by the 20th, including the types of stablecoins being piloted, service launch schedule, Meta Pay changes, contract structure with third-party issuers, privacy protection, and measures to prevent illicit finance." She further pointed out, "If Meta uses a specific stablecoin on a platform with 3.5 billion users, it could significantly impact financial stability." Previously, Meta announced that it would offer stablecoin options as a method for some creators to receive payouts.
