Lately I've been thinking about MEV. Basically, it's when someone on the chain can "cut in line." It seems like just miners/validators earning a small tip, but it often affects us retail investors who are quick or slow: for the same swap, you think it executes in the order you clicked, but someone ahead of you gets a higher priority, and slippage suddenly skyrockets. Last night, I saw a transaction with the address 0x9f3…a21 on the chain. The pool's spread was decent at first, but on the next block, it got sandwich attacked, and the gas fee inexplicably increased. It was pretty frustrating. The word "fairness" is indeed a luxury on the chain; the right to order transactions is power... All I can do now is avoid chasing hot tokens, set limit orders/small split trades, and accept being slower. By the way, hardware wallets are sold out, phishing links are everywhere. People’s security awareness has improved, but don’t just focus on "storage." Clicking authorize or signing is just as deadly—anyway, I’ve already opened the umbrella.
