Recently, hardware wallets have been out of stock, and phishing links are everywhere, which makes me more interested in the "trustworthiness of the project's underlying technology." My simple method for beginners: first, look at GitHub—not by star count, but by whether someone has recently committed code, fixed bugs, or responded to issues; then review the audit reports, don't just focus on the words "passed/ audited," but pay attention to whether risks are clearly listed, whether rechecks have been done, and which issues have been accepted as "known but unchanged." Finally, check the multi-signature upgrade: who can sign, how many people are required, and whether there is a timelock (giving you time to react). Honestly, if you can't understand these things, it's okay; just being able to judge "whether someone is managing it, how they manage it, and who takes responsibility if something goes wrong" is enough. Anyway, I only see one key that can upgrade, so I’ll just avoid it for now.
