Seems like a hybrid crypto platform. Like a platform that features both the functionalities of Dex and Cex. Here's a brief explanation about this concept.
A hybrid crypto exchange combines the features of centralized and decentralized exchanges to provide a unique trading experience. It brings together the benefits of both types of exchanges, offering users enhanced security, liquidity, and control over their assets.

Recently some exchanges have begun to incorporate some Dex features into their platform. For instance, on Bitget exchange, one can easily swap tokens using Bitget swap. Bitget Swap is a decentralized trading product of Bitget which makes popular on-chain assets available automatically on a regular basis.

Eidoo, Stoxum, Qurrex, these are other examples of hybrid exchanges. Never used them before and I can't say exactly how they operate and the various regions they're available to.
