I find my own L2 logic pretty straightforward: for everyday small interactions and frequent operations, I put them on L2; the mainnet only does two things—large transfers and “final settlement.” To put it plainly, the mainnet is expensive but reliable, while L2 is cheap but requires you to stay extra alert (cross-chain bridges, withdrawal timing, and contract permissions—I’ll genuinely go check the code and permissions). Recently, there’s been more arguing about miner/validator income, MEV, and ordering fairness, and I understand how irritated retail users get when they’re squeezed… so when I place orders, I lean more toward limit orders, chase fewer hot pools, and if I can split orders, I’ll split them—don’t treat yourself like a delivery service. Want to optimize both experience and gas at the same time? Basically not possible. Anyway, I’ll stick with the principle of “use L2 for everyday transactions, go back to the mainnet for anything critical,” and just get through it for now.
