Tether CEO Paolo Ardoino announced that Tether has frozen over 1.567 billion USDT linked to a suspected security breach at Binance, stating that protecting the industry and partners is its top priority. Circle had previously frozen approximately 823 million USDC related to the same incident, bringing the combined total of frozen stablecoins to roughly $2.39 billion. Binance confirmed it is investigating a potential security issue but has not yet verified any impact on user funds. The coordinated freeze by both major stablecoin issuers highlights the growing role of centralized token issuers in responding to exchange-level security threats.
