Today I suddenly felt a little scared: I almost clicked a “wallet upgrade” link—luckily I was quick and shut it down… Recently, phishing has really been on the rise, hardware wallets are out of stock, and everyone is feeling anxious about patching up their security.

As for block builders and the bundle system—honestly, retail users don’t need to study to the extent of “going to be a builder themselves.” Just know these three things: 1) The transactions you send might not get into the block in the order you see; in between, someone else will package them and even cut the line; 2) Don’t sign authorizations carelessly, especially those that grant you permissions all at once to the sky and beyond; 3) If you want to get less sandwiched, use reputable wallet/router anti-sandwich options—if the amount is bigger, split it into batches, and don’t go all-in at once so you don’t make yourself too conspicuously exposed.

Anyway, my bottom line right now is: if I don’t understand it, I won’t click; I’ll pause signatures for three seconds first; I’m willing to rant about DAO votes, but I don’t dare to mess with my wallet. That’s it for now.
