# Detect Wallet

Adena enables web applications to interact with the Gnoland blockchain, allowing users to sign and broadcast transactions.

Once the Adena Wallet Chrome Extension is installed on the user's device, the `adena` object will be injected into the `window`. To **detect the installation of Adena Wallet**, look for `window.adena`. If Adena is not installed, we suggest directing your users to [our website](https://adena.app/) on a new tab. 

#### Sample Code

```javascript
window.onload = async() => {
  //look for the adena object
  if (!window.adena) {
    //open adena.app in a new tab if the adena object is not found
    window.open("https://adena.app/", "_blank");
  } else {
    //write your logic here
    //the sample code below displays a method provided by Adena that initiates a connection
    await adena.AddEstablish("Adena");
  }
};
```
