Binance have launched a DEX that doesn't require KYC as far as I know and its quite user friendly just it hasn't received the same volumes as the CEX version of the exchange, but these services may become more popular as more regulation is put into place that requires FATF guidelines to be followed and they can still operate without these restrictions
They already have the CEX version so that DEX version they have is unlikely to implement KYC. But we can't be confident at these moments that they will never change that status of not implementing it because just like IDEX, they can implement it by simply making reasons.
i never seen a decentralized exchange that require a kyc but centralized version
IDEX did.
