# Initialization

After installing the Wepin Compose Multiplatform Widget Library, the next step is to initialize the SDK. SDK initialization involves creating an instance of `WepinWidgetSDK` and using the `init()` function to proceed.

## Import SDK

To use the Wepin Compose Multiplatform Widget Library, you first need to import the SDK. Add the following import statements:

```kotlin
import com.wepin.cm.widgetlib.WepinWidgetSDK
import com.wepin.cm.widgetlib.types.*
```

## **Creating and Initializing the** `WepinWidgetSDK` **Instance**

Before creating an instance of `WepinWidgetSDK` , you must register your app's Android/iOS information in the Wepin Workspace.

{% content-ref url="../../../wepin/workspace" %}
[workspace](https://docs.wepin.io/en/wepin/workspace)
{% endcontent-ref %}

Using the registered app information, create an instance of `WepinWidgetSDK` .

```kotlin
private val wepinWidgetSDK: WepinWidgetSDK= WepinWidgetSDK(
    WepinLoginOptions(
        context = context,    //Android: Context, ios: UIViewController
        appId = appId,
        appKey = appKey
    )
)
wepinWidgetSDK.init(WidgetAttributes(defaultLanguage = "ko", defaultCurrency = "KRW"))
```

**Parameters**

* **attributes** \<WidgetAttributes> - Widget properties to define during initialization.
  * **defaultLanguage** \<String> - Set the default language of the widget. The default value is `ko`, and currently supported languages are `en` and `ko`.
  * **defaultCurrency** \<String> - Set the default currency of the widget. The default value is `KRW`, and currently supported currencies are `USD` and `KRW`.

**Returns**

* **\<Boolean>**

## **Checking Initialization Status (isInitialized)**

You can check whether the `WepinWidgetSDK` instance has been successfully initialized by using the `isInitialized` method. &#x20;

The return value is as follows:

* **\<Boolean>**\
  Returns `true` if initialization was successful, and `false` if it failed.

```dart
if(wepinWidgetSDK.isInitialized()) {
    // Success to initialize WepinLogin
}
```
