Tether2026-09-09 06:01:05Bitrace says Tether froze 50 addresses, with over $45 million tied to Xinbi Guarantee affectedTether has frozen 50 blockchain addresses in a move tracked by blockchain security firm Bitrace, with more than $45 million linked to Xinbi Guarantee caught in the action. According to Bitrace, the frozen set included 22 business addresses associated with the Southeast Asian illicit crypto guarantee platform. Bitrace said the operation did not stop at Xinbi Guarantee’s core transaction flow. The freeze also covered recent business addresses used for deposits, transfers, and payouts, along with the outgoing hot wallet address of Xpay, an illicit payment tool tied to the group. Some third-party illicit entity addresses that had maintained close fund flows with Xinbi Guarantee were also included. The firm drew a distinction between this case and an earlier single-address freeze involving Huione Pay and North Korea-linked hackers, saying the current action expanded to related business addresses as well. Bitrace added that on-chain enforcement was still ongoing as of Sept. 9, 2026. It also said temporary replacement business addresses activated by Xinbi Guarantee after freezes on Sept. 8 were frozen again the same night, with less than 12 hours between the two actions.760
