I just want to ask you, OP, why do you want to use Dex?
I do not trust CEX. I operate with small amounts, so I'm looking for the cheapest swap (dex) and cheapest L2 network.
personally I just don't bother I just go to the most crowded L2 just for the sake of liquidity.
because imagine you are paying low fee yet the slippage is 5%, you literally lost the 5%.
It's a good advice.
How to find the most crowded L2? How to determine that L2 is crowded? Sorry for noob question
