Digital asset management app

My project is about creating a digital asset management app for a decentralized car pool that is compatible with both iOS and Android. The primary functionalities of the app will be to not only store and organize digital assets, but also to manage permission and access control. On top of that, I would also like integrations or connections to external platforms (e.g. social media integration to be included). This app should be robust and highly secure, and provide an efficient way for users to manage and access their digital assets.
