+### Configuring the Client
+
+The Flutter Wallet SDK uses the standard Client from the [http package](https://pub.dev/packages/http) for all network requests (excluding Horizon, where the Flutter Stellar SDK's HTTP client is used).
+
+Optionally, you can set your own client from [http package](https://pub.dev/packages/http) to be used across the app.
+
+The client can be globally configured:
+
+<CodeExample>
+
+```dart
+import 'package:http/http.dart';
+// ...
+
+// init and configure your HTTP client
+// var myClient = ...
+
+// set as default HTTP client
+var appConfig = ApplicationConfiguration(defaultClient: myClient);
+var walletCustomClient = Wallet(StellarConfiguration.testNet, applicationConfiguration: appConfig);
+```
+
+</CodeExample>
+
+Some [test cases](https://github.com/Soneso/stellar_wallet_flutter_sdk/tree/main/test) of this SDK use for example the `MockClient`.

 Our second identity uses an email as an auth method. For that we can't use a [SEP-10] auth token for that server. Instead we need to use a token that ties the email to the user.
