Tether的钱包黑名单过程中的这一滞后允许超过7800万美元的非法资金在执法行动生效之前被移动

A lag in Tether’s wallet blacklisting process allowed over $78 million in illicit funds to be moved before enforcement actions took effect, according to a new report by blockchain compliance company AMLBot.

根据区块链合规公司Amlbot的一份新报告，Tether的钱包黑名单流程的滞后使超过7800万美元的非法资金在生效之前就可以移动。

The report, published May 15, claims that Tether’s address blacklisting on Ethereum and Tron usually becomes effective only after a considerable delay from when the process is initiated.

该报告于5月15日发布的报告声称，Tether的地址在以太坊上进行黑名单，而Tron通常只有在启动该过程的延误大量延迟后才能生效。

This delay stems from Tether’s multisignature contract setup on both Tron and Ethereum, transforming what should be an immediate compliance action into a window of opportunity for illicit actors, according to AMLBot.

根据Amlbot的说法，这种延迟源于Tether在Tron和以太坊上的多词合同设置，将应该立即的合规行动转变为非法演员的机会之窗。

Tether’s blacklisting procedure is a multi-step process with a first transaction effectively warning of the upcoming blacklisting. First, a Tether administrator multisignature transaction submits a pending call to “addBlackList” on the USDT-TRC20 contract.

Tether的黑名单程序是一个多步骤过程，首次交易有效地警告即将到来的黑名单。首先，系绳管理员多签名交易将悬而未决的呼叫提交给USDT-TRC20合同上的“ AddBlackList”。

This results in a public “submission” of the target address as a blacklist candidate. This is followed by a second multisignature transaction confirming the submission, resulting in an “AddedBlackList” emission, making the blacklisting effective.

这导致目标地址作为黑名单候选人公开“提交”。接下来是第二次多签名事务，确认提交，从而导致“添加布莱克列表”排放，从而使黑名单有效。

A warning on incoming blacklisting

警告传入的黑名单

In one example shared with Cointelegraph, an onchain transaction submitting a Tron address as a blacklist candidate took place at 11:10:12 UTC. The second transaction that actually enforced the action did not occur until 11:54:51 UTC on the same day, a 44-minute delay.

在与Cointelegraph共享的一个示例中，提交TRON地址作为黑名单候选人的OnChain交易发生在UTC 11:10:12。实际实施该动作的第二笔交易直到同一天11:54:51 UTC才发生，这是44分钟的延迟。

In practice, this delay can be treated by owners of USDt about to be blacklisted as a notice to move their assets to avoid them being frozen. The report stated:

在实践中，USDT的所有者可以将这种延误列入黑名单作为移动其资产以避免被冻结的通知。报告指出：

The report says that “for blockchain-savvy attackers, these delays are golden.” By tracking Tether’s calls in real time, a fraudster can be instantly alerted that his address is being targeted. When asked by Cointelegraph whether the delay is a technical limitation or just a delay in the actions of a multisignature wallet key holder, AMLBot researchers said that they cannot determine it without knowledge of Tether’s internal procedures.

该报告说：“对于精通区块链的攻击者，这些延误是黄金的。”通过实时跟踪Tether的电话，可以立即提醒欺诈者的地址是针对的。 Amlbot研究人员说，当Cointelegraph被Cointelegraph询问延迟是技术限制还是延迟延迟的延迟，或者是延迟的延迟，而多准字母钱包密钥持有人的行为是在不了解Tether的内部程序的情况下就无法确定它。

In a statement to Cointelegraph, a Tether spokesperson explained that “while any delay in enforcement should be examined, the idea that this represents a systemic loophole is both misleading and lacking perspective.” According to the company, it collaborates with law enforcement to freeze addresses on a daily basis. The statement continues:

系绳发言人在给Cointelegraph的一份声明中解释说：“尽管应检查执行的任何延迟，但这代表系统性漏洞的想法既具有误导性，又缺乏观点。”据该公司称，它与执法部门合作每天冻结地址。声明继续：

According to Tether, the delay cited in the report stems from its multisignature governance model, which is said to prevent unilateral freezes and protect the system’s integrity. Tether admits that the model also introduces a delay on enforcement, noting that “it’s a trade-off for responsible responsiveness to a $100+ billion ecosystem,” with improvements on the way:

根据Tether的说法，报告中引用的延迟源于其多符号治理模型，据说这可以防止单方面冻结并保护系统的完整性。 Tether承认，该模型还引入了执法延迟，并指出“这是对100亿美元生态系统的负责任响应的权衡”，并有所改善：

Not just theoretical

不只是理论

AMLBot said its data shows that over $28.5 million in USDT was withdrawn during the lag period between the two transactions on the Ethereum blockchain. This amount of freeze avoidance occurred between Nov. 28, 1997, and May 12, 2025. The average amount moved during the lag exceeded $365,000.

Amlbot表示，其数据表明，在以太坊区块链的两项交易之间，在两次交易之间撤回了超过2850万美元的USDT。这种冻结数量发生在1997年11月28日至2025年5月12日之间。滞后期间的平均金额超过365,000美元。

Similarly, $49.6 million was reportedly withdrawn during freeze lag windows on the Tron blockchain, resulting in a total on Ethereum and Tron of $78.1 million. Exploiting this lag on Tron is not particularly rare, according to AMLBot:

同样，据报道，在Tron区块链上的冻结滞后窗口中撤回了4,960万美元，导致以太坊的总数为7810万美元。根据Amlbot的说法，在Tron上利用这一滞后并不是特别罕见的：

A Tether spokesperson said that “the $76 million referenced in this report should be put in context of the more than $2.7 billion in USD₮ that Tether has successfully frozen and blocked to date.”

系绳发言人说：“本报告中提到的7600万美元应计入超过27亿美元的美元，该tether已成功地冻结并被封锁。”

Tether has previously promoted its ability to freeze assets as a compliance feature. In 2024, Tether, Tron, and analytics firm TRM Labs cooperated to freeze over $126 million in USDT linked to illicit activity.

Tether此前曾促进其将资产作为合规性功能的能力。 2024年，Tether，Thron和Analytics公司TRM Labs合作冻结了超过1.26亿美元的USDT，与非法活动相关。

Still, the AMLBot report raises questions about the effectiveness and speed of those enforcement actions.

尽管如此，AMLBOT报告仍提出了有关这些执法行动的有效性和速度的疑问。
