Xiao Bai question: Is there black U in this circle?

Answer: No! Don't be deceived by scammers in the Telegram group!

There is no black U; regardless of which chain's USDT contract, there is no method written to blacklist USDT, so there is no black U for USDT.

There are black addresses, which means the address has been frozen by an exchange or, like the Tornado event, frozen by the FBI in the United States. In that case, you cannot transfer to an exchange for trading, but decentralized wallet transfers are possible.

Technically speaking, all on-chain transactions are publicly broadcast. If a frozen wallet transfers to a non-frozen wallet, honestly, the exchange should simply freeze those with significant associations. If every wallet that has made a transfer gets frozen, then many underground money houses wouldn't need to operate; they'd all be frozen.

So the conclusion is that USDT has no black, but wallets can be blacklisted. Generally, receiving a transfer from a blacklisted wallet is not a problem.
