The app will be built on three main sections, Pay, Save and Earn (for example as bottom tabs), plus the elements that are global to all of them: your identicon and account, the always-visible entry point to Mini Apps, the notifications panel and the settings. Mini Apps are deliberately not a fourth tab. They are global, “in everything”: a Mini App that extends payments shows up in Pay, one that adds an asset shows up in Save, and so on.
For end users the entry point is simply called “Apps”, with two views: “My apps” (saved, pinned and recently used) and “Explore” (the catalog, plus a browser-like address bar to open any Mini App whose URL you know).
