Modularization, DA layer, and these terms sound pretty exciting when developers talk about them. As an ordinary user, I only care about one thing: don't compromise your wallet just for a quick "interaction." Never store seed phrases on websites/forms/cloud storage; if you need to back up, write two offline copies and keep them separate. Don't just click confirm when you see a pop-up for signing; some transactions aren't transfers but can grant permissions that last forever, and later someone can wipe everything with a single click, making you think the chain is broken... My current red lines are: don't click on unfamiliar links, give as few permissions as possible, use a secondary wallet for interactions, and only receive funds with your main wallet without signing randomly. Phishing sites are made to look exactly like official ones—don't find it troublesome, just pay more attention to the domain name to save yourself trouble.
