Slow Mist Cosine posted on the X platform that if you are still using Safe multi-sign or other multi-sign (regardless of the technical mode), you need to pay attention to these points: 1. All signature steps must be verifiable. If you find a friend who understands technology and can't verify it for a long time, you should be suspicious by default; 2. Since they have used more signatures, if they can be matched with hardware wallets, especially those that can analyze complex signatures and notice abnormal signatures, it is best to use them together. The security approach is to never trust one party. There may always be a single point of risk, and it is best to verify it with multiple parties.
