Using decentralized crypto exchanges

As-salamu alaykum,

Using decentralized cryptocurrency exchanges such as Uniswap, QuickSwap or PancakeSwap is permissible or not? I mean just the swap function not yield farming or liquidity.
I’ve seen this on https://www.islamicfinanceguru.com/crypto/ But I want to be sure.

Exchanging using Uniswap itself is fine.
