# What Should I Do if My Wallet Receives Blacklisted USDT (Black U)?

If your wallet receives Black U (USDT flagged as potentially linked to illegal activities), you should immediately stop using the address and create a new sub-address in your wallet. Steps are as follows:

1. Enter the **Address Book**.<br>

In addition to these steps, we recommend:

* Using an [**AML tool**](/risk-management/aml-query.md) to verify if the source address of the transaction is listed as high-risk.
* Notifying your legal or compliance team to evaluate the legal risks and address the situation appropriately.
