I accidentally copied the wrong address for a swap just now, my heartbeat immediately spiked... Luckily, I noticed it on the wallet confirmation page. Also, I want to briefly talk about the block builder/bundle system; retail investors don't need to study it to the point of being able to draw flowcharts, just knowing that "my transaction may not go directly into a block, it might be bundled or front-run" is enough. Basically, there are only a few things you can do: don't use unknown private RPCs, don't rush into pools with very low liquidity, don't set slippage too loose, and when you see MEV protection/private submission, just treat it as "try to avoid being front-run as much as possible," don't expect 100% immunity. On the macro side, expectations of rate cuts will sometimes cause the dollar index and risk assets to rise and fall together; when market sentiment is very conflicted, it's easier for people to chase after trades recklessly... I still follow my old habit: first look at liquidity withdrawal and worst-case scenarios, and don't treat "being bundled" as some kind of mysticism.
