Or do you mean that these two types belong to the same exchange but are separate in their application as Binance used to have a DEX version of the exchange?
Not that, Op doesn't want a DEX version of a central exchange, he wants a hybrid exchange that combines DEX and CEX together in one exchange, I don't expect there is anything like this at the moment. DEX and CEX differ from each other in many theoretical and technical details.
But there are some central exchanges that provide services similar to DEX, such as a swap with instant liquidity, where you can swap any Coin you want while providing instant liquidity. You can also participate in the liquidity pool and obtain a daily or monthly return.
That's true buddy, yeah there are and I've been introduced to one(bitgetswap) by a contributor here. I've been exploring the functions and I'm satisfied with their cross chain swap feature.
