Mobile App

The HostraCore mobile app (iOS, Android) lets users buy USDT/USDC with a card, view transfer history and receive push notifications about transfer status. The app is currently in App Store review.

What the app does

  • Buy USDT or USDC with a card — the same card_to_crypto saga the API exposes.
  • Choose network: Tron, Ethereum, Polygon or BSC.
  • See the server-side quote (rate and fee) before confirming.
  • Transfer history with saga state and both legs.
  • Push notifications on every transfer.status_changed event via Expo.

Get the app

App Store review in progress.

The TestFlight and App Store links, plus a scannable QR code, are published here as soon as review completes. For early access write to support@hostracore.com.

How the app connects

The app talks to the same production API as this website: quotes are locked with POST /v1/quotes, transfers run through POST /v1/transfers, and status changes arrive as webhooks that are forwarded to the Expo push pipeline with an opaque payload containing only the transfer identifier.
