+## Tracking the creation of wallets
+
+The events are similar to the events for updating the balance, only for the creation of a wallet. A frequent case of transferring data via websockets to the front-end.
+
+Version 7.3 introduces an interface to which you can subscribe.
+This is done using standard Laravel methods.
+More information in the [documentation](https://laravel.com/docs/8.x/events).
+
+```php
+use Bavix\Wallet\Internal\Events\WalletCreatedEventInterface;
+
+protected $listen = [
+    WalletCreatedEventInterface::class => [
+        MyWalletCreatedListener::class,
+    ],
+];
+```
+
+And then we create a listener.
+
+```php
+use Bavix\Wallet\Internal\Events\WalletCreatedEventInterface;
+
+class MyWalletCreatedListener
+{
+    public function handle(WalletCreatedEventInterface $event): void
+    {
+        // And then the implementation...
+    }
+}
+```
+
+It worked!
