Tether CEO Confirms Freezing of 3.29 Million USDT Linked to Rhea Finance Hacker Address
Tether CEO Paolo Ardoino confirmed in a public statement that Tether has frozen 3.29 million USDT associated with the hacker address of Rhea Finance, emphasizing that the company takes such incidents "very seriously." He also stated that this action was based on a rapid alert and collaboration from the on-chain tracking service provider zachxbt.
Multiple English media outlets and exchange announcements noted that the frozen USDT originated from a recent attack on Rhea Finance, with Tether directly locking the funds at the target address through centralized control to prevent further transfers by the hacker. This operation highlights the "freezable" authority of stablecoin issuers in on-chain fund flows, contrasting sharply with the uncontrollable nature of native assets like Bitcoin.
In the context of ongoing pressure on the overall security environment of DeFi, Tether's freezing action, along with its previous large-scale fund recovery plan for the Drift protocol, constitutes a model of "centralized stablecoins as a risk buffer layer," supporting the recovery of certain protocols while reinforcing USDT's core position in on-chain settlements.

冻结USDT并非单纯技术动作，而是对“稳定币属性”的一次再定义：它既宣称自己是链上资产，又保留准金融监管机构的“可逆权限”。当Tether能单点冻结特定地址的资金，USDT的“似现金”承诺与“可被暂停”风险并存，形成一种“去中心化外壳、中心化控制内核”的结构。
这一结构在黑客攻击频发的DeFi生态中具有双重效果。一方面，它可以快速冻结被盗资金，降低项目与用户损失，从而增强协议对USDT的依赖；另一方面，它也揭示了稳定币对货币政策的“准公共化”倾向：Tether在无需司法机构前置裁定的情况下，即可对链上交易实施限制，这与传统央行对银行账户的控制权高度相似。
从更宏观视角看，Tether选择冻结而非“无视”，本质上是在强化其“基础设施”定位。当USDT被广泛用于跨协议结算与风险对冲时，Tether对异常流动的控制能力会进一步固化其结算地位，形成“越关键，越有权干预”的正反馈。问题在于，这种权力在缺乏透明规则与外部监督的情况下，可能随时间演变为新的单点风险节点，而非纯粹的“安全垫”。
