Staring at the screen until my eyes are dry, I just scanned a swap on the blockchain, and the slippage clearly shouldn't be that large. When I clicked to check, I saw two transactions sandwiching each other, the same old sandwich pattern. Honestly, you might think it's an "opportunity," but most of the time it's just someone else paying extra fees + gas, while you conveniently push the price to their arbitrage route.

Now before I place an order, I first look at the pool depth and the trading density of the last few blocks. If it's too hot, I’d rather take a detour; spending a bit more time is better than being caught in a sandwich. By the way, I’ve been thinking about the recent NFT royalty debates—creators want money, secondary markets want liquidity, and traders just want to avoid getting eaten too badly... Anyway, in the end, the costs will always somehow land on the buy and sell orders. That’s it for now, I won’t get itchy today.
