Today, the on-chain congestion is as crowded as an elevator during mealtime. I made a swap and queued in the mempool, watching it change from "Almost executed" to "You have over 999 people ahead of you"... What's more frustrating is that you think you're waiting in line, but you're actually being squeezed: others add more gas to jump ahead of you, and with a slip, the execution price is completely different from what I imagined when I placed the order. To put it simply, during congestion, your transaction will experience: waiting, being front-run, being squeezed, and finally either failing with a small fee paid or executing with a big slip. Recently, memes and celebrity calls have been coming one after another. When newcomers get excited and rush in, I can only mutter as an old hand: don’t rush to take the last baton, first learn to set stop-losses and read the order book depth, or you’ll queue up to get beaten. Anyway, I’ll tighten my slippage settings first—better to fail than to be a sucker...
