# Terra Station Mobile App

Terra Station Mobile is an application that enables users to interact with Terra Core.

Terra Station Mobile allows users to:

- Create wallets and send tokens
- Get involved with staking by browsing through validator information and delegating Luna tokens.
- Atomically swap currencies on the Terra network at the effective on-chain exchange rate
- Use QRCodes for easy interactions when sending assets and recovering wallets

## URL Scheme

Terra Station Mobile includes a custom [URL Scheme](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app) that lets developers trigger different actions in the app.

These URL handlers can be opened by scanning a QR code or opening the link directly.

### Send

The send function allows a user to send a specified amount of funds to a recipient. This function can be used to accept payment for goods and other point-of-sale configurations.
