Recently, the issue of black U tokens has become quite serious. I just found a pretty useful tool on MistTrack that can directly check whether your wallet address is at risk of black U tokens, so you don't have to worry every day. I tried it out, and the U address query feature is very convenient—just enter the address to quickly detect.

However, the official also mentioned that this query is mainly for AML security research purposes, so the data may not be 100% accurate. They are continuously optimizing it. But having such a tool is better than not, especially for people who frequently receive tokens.

By the way, I checked the market, and BTC is around 67.30K, up 0.54% in 24 hours; ETH is at 2.07K, also up 0.58%. If you're worried about the risk of your U address, why not give it a try? It's a free tool, and having an extra layer of protection never hurts.
