# Open DApp

App Links allow you to generate a hyperlink that when used will direct users to your DApp within Nova Wallet's DApp browser. The DApp must be listed in Nova Wallet's DApp Catalog or the App Link will not work. To add your DApp to Nova Wallet's DApp catalog follow this guide: [add-your-dapp-to-nova-wallet](https://docs.novawallet.io/nova-wallet-wiki/misc/developer-documentation/add-your-dapp-to-nova-wallet "mention")

## Clickable App Link

This is how you format App Links to open DApps. When a user clicks this link they will be directed to your specific DApp within Nova Wallet's DApp Browser.

App Links to open a specific DApp are formatted as such:

`https://app.novawallet.io/open/dapp?url={YOUR_DAPP_URL}`

Here is an example App Link which will open the Hydration app within Nova Wallet.

<https://app.novawallet.io/open/dapp?url=https://app.hydration.net/trade/swap>

## QR Code with App Link

Now that you have your App Link you can make a QR code containing its data, which when scanned with a user's mobile phone will open the DApp in their Nova Wallet. You can use a site such as [QRCode Monkey](https://www.qrcode-monkey.com/) to generate these QR codes easily.
