USDT blocks arrive suddenly — and afterwards $1.2B has already burned irreversibly.
Frozen on addresses
USDT on ETH + TRON, 9,735 addresses. Assets remain but cannot move — isBlackListed == true.
Full destruction of funds
Zeroed by Tether's decision — links to OFAC / sanctions / fraud. Cannot be recovered.
Median preban → ban
Time between the early warning and the actual block execution. In this window you can move USDT, dispute an error, or document a counterparty.
Full history
Events since USDT deployment (2017-11). Cross-checked with on-chain via QuickNode archive — zero gaps.
How we catch the signal
From Tether's intent to block an address to the actual freeze, hours pass. We detect it at the earliest stage.
Early detection
We monitor on-chain in real time. When an address enters Tether's block queue, we capture the signal before the freeze actually executes.
Intent verification
We confirm the chain and address, capture the balance at the time of the signal, and deduplicate against known events. Only confirmed signals reach the channel.
