“My USDT is frozen.” In practice, that sentence hides two very different problems. Distinguishing between an exchange freeze and an issuer freeze is the first meaningful step of any recovery — and one that is routinely skipped in the first weeks of a case.
Exchange freeze
An exchange freeze is operational. A platform — Changelly, a centralised exchange, a broker — holds funds in its own books, pending compliance review or a request from an upstream counterparty. The tokens are still fungible on-chain; only the account access is restricted. Levers here are commercial, procedural, and, where necessary, jurisdictional.
Issuer freeze
An issuer freeze is protocol-level. Tether has added the wallet to the USDT blacklist, and the tokens are stuck in the wallet itself. Levers here are narrower — the counterparty is the issuer, the process is documented, and no third-party exchange can unlock what the contract has locked.
How to tell which you’re facing
Look at three things: who last controlled the funds, whether the balance is visible on a block explorer at your address, and whether any transfer attempt reverts on-chain. Those three signals almost always separate the two cases in one review.
