Just refreshed the lending dashboard and saw someone say "a lot of risk-free arbitrage on-chain," and I couldn't help but laugh... What you see as an opportunity, others see as your transaction fee plus slippage. The sandwich attack thing is even more frustrating; you just click confirm, and the next second, the transaction price seems to be pulled away, and when you look back, there are two orders stuck in the block, making you feel like the bacon in the middle. Anyway, I now split large transactions into smaller ones, and I don't chase after hot pools anymore. I won't go into places with insanely high interest rates either; when the liquidation waterfall hits, no one can escape. Recently, testnet points are getting competitive again, and people are arguing every day about whether the mainnet will launch tokens or not. I'm too lazy to guess anymore; in the end, it's probably just working for arbitrage bots. You say "then I can just enable MEV protection"... but it doesn't always save you.
