I need some information about Defi farming and liquidity, and also how save if paraswap and quick swap for liquidity returns? Have anyone did this successfully before? Please give me some guidance about safety and more.
How about checking out pancakeswap? It has farming and pool which is the very reason why many users are into it and details are all over there if you you're into farm and LP.
Aside from it, there are too many other swaps that have that feature and you just have to research each of them. And for reference and start, here's a checklist for you.
