These past two days, I’ve been looking at terms like “block builder/bundle.” Basically, it means someone helps package your transactions into a block, and the order can also be arranged. How much do retail investors need to understand? I think knowing three points is enough: 1) Tapping confirm on-chain doesn’t mean the next second it will execute in the order you see; 2) Getting sandwiched or being sniped isn’t necessarily because your hands are slower—someone else may be better at “bundling”; 3) When using a wallet/router, at least check whether it supports private sending and whether there are anti-sandwich options—don’t just leave everything on default.

Recently, AI Agent automated trading has been quite popular again. A lot of people are touting “fully automatic money-making,” but I’m more concerned about how it signs, who it grants authorization to, and whether you can revoke it at any time. Anyway, my current approach is: test with small amounts, give as few permissions as possible, and if I truly go for automatic interactions, I’ll save the revoke link first… for now, that’s it.
