# Environment Variables

Create a `.env` file in the root directory with the following variables:

{% code overflow="wrap" %}
```bash
# Wallet backend URL
WALLET_APP_API_URL="http://localhost:3018"

# URL of beneficiary app - i.e, the app that will load the wallet app in an iframe
REACT_APP_PARENT_APP_ALLOWED_ORIGIN="http://localhost:5173"
```
{% endcode %}

## Notes

* Never commit .env with real values to version control.
* For production deployment, ensure HTTPS URLs and secure API tokens.
* Verify all external services are accessible before running the UI.
