My favourite invention in crypto is Uniswap range orders. Most crypto apps are alternatives to stuff that have existed, but Uniswap range orders are largely unique, offers a great way to scale in and out of positions, and earn while you're doing it! That and ZKPs as a broader category, of course.

I haven't been following, any recommendations?

interested in any zk privacy projects? there seem to be a lot in development rn

I was thinking the other day I need an easy automated way to close them when filled so I don’t retrace and sell the position later

Pretty much just native uniswap limit orders
