Thanks. You know which one swaps for monero/XMR?
I don't think there is an existing DEX for Monero. Most of the top DEX that exists today are operating under Ethereum based protocol which make it impossible for you to find an decentralized exchange for XMR, they are also subject for high fees due to an increasing volume of trades and continuous price surge. Theoretically, though, DEX are still centralized in some point, meaning these exchanges are still prone to hacks that could result to a complete shutdown of their services. They still have their own server to match their customer's trading order.
If you are worried about having KYC, then you can just use Binance for you to be able to trade your XMR without having to undergo KYC/AML procedures. Binance only requires KYC if you wish withdraw 2 BTC daily. Moreover, below are the following pairs for you to trade either at market/ limit order in the spot market.
