Seeing someone's U was stolen definitely makes people worried. However, the wallet risks exposed behind such incidents are worth everyone being alert to.

Let's break down the logic of this case: the wallet stored 7000U, and after verifying that the wallet functions properly, it indicates that the private key is still in hand in the short term. Where is the problem? Once a transfer is sent, it disappears in seconds, which precisely shows that the other party has either controlled the multi-signature wallet's decision-making authority or set a trap from the beginning—through contract authorization, phishing links, or fake transaction pages, making you voluntarily relinquish control of your funds.

Many people’s first reaction to such situations is to report to the police. But honestly, once a transaction on the blockchain is confirmed, it becomes an irreversible record. By the time the police respond, the funds have long flowed to overseas addresses. Instead of hoping for post-event tracing, it’s better to understand a few common traps beforehand: wild multi-signature wallets, fake contract authorizations, high-yield bait.

The crypto world is indeed deep, but many pitfalls can actually be avoided in advance.
