Last night, I was going through on-chain records and it was overwhelming, then I saw a bunch of people criticizing MEV as "cutting in line." Basically, the ones most affected are small users who follow tutorials step-by-step: you think that just confirming your transaction puts you in line, but in reality, someone adds a tip or directly inserts you in the middle, and your swap price slips away, sometimes even before you see any useful interaction trace, and you end up paying the cost.

Now I have to include "failures/being front-run/retries" in my task list; if possible, use limit orders instead of market orders, split into batches when possible, and avoid rushing into low-liquidity pools. Fairness on the blockchain is quite a luxury—whoever controls the ordering has the power to decide whether you're just a user or "material."

Also, hardware wallets are out of stock lately... even more outrageous are the phishing links flying everywhere. During such chaotic times, don’t rush to click on "re-sign" or "claim airdrops" links. My principle remains: only perform verifiable actions, and before signing, ask yourself, "What exactly am I authorizing?" That’s all for now.
