A Mini App is a web app you host on your own domain. It runs inside uOS in a sandboxed iframe window, appears in the App Store when published, and installs to the user’s desktop. You need three things:
  1. A manifest at /.well-known/uos-app.json
  2. Optional SDK (/uos-app-sdk.js) so your app can talk to the wallet and shell
  3. A publish from Dev Portal (wallet message signature, no gas)
Publishing is self-serve and immediate. Set author.wallet in your manifest to the wallet you sign with in Dev Portal.
