Yes, it does.

Moralis v2 is comprised of an all-API service that is built based on the REST API standard, which can be called in any programming language. Using the various functions and libraries such as fetch, axios, and others you should be able to call Moralis APIs in React Native easily.

Alternatively, you can also call Moralis API indirectly from the backend. Moralis v2 currently provides SDK to call the API easily in both NodeJS and Python and by building a server with the SDKs, you should be able to use the backend as a proxy to call Moralis API for your React Native decentralized application.
