How to Improve Team Communication with Digital Technologies

Our team is constantly working with various web frameworks, both new ones, which have just appeared on the IT market, and old ones that have already gained a certain reputation. We test such solutions, try to better or adapt them, and then we share our experience with you. This time we're going to discuss popular Angular dialog windows and our attempts to improve them.
We&rsquo;ll explain to you how to implement a dialog window in the most efficient way. You'll find a lot of details on Angular, read how to open dialogs without file size increasing, and so on.
<h2 dir="ltr" style="text-align: justify;">AngularJS or Angular?</h2>
AngularJS has a pretty impressive history that goes back over 10 years (since 2009). The framework was initially developed by Adam Abrons (who is no longer part of the project) and Mishko Hevery (who keeps improving the solution in question with the assistance of Google and its highly qualified employees).
If some web developers consider HTML &ldquo;an enemy to fight against&rdquo;, the creators of Angular.JS decided to take a different path. They expanded the possibilities of HTML syntax by introducing additional directives, which are one of the key features of AngularJS.
In addition, AngularJS developers believe that the code should be covered as much as possible with tests (in order to avoid future bugs). Therefore, the framework was initially friendly in writing tests.&nbsp;
And yet, despite a number of advantages, AngularJS had a few performance disadvantages (and not only performance ones). Therefore, in the spring of 2014, it was decided to completely update and improve the framework (so to speak, create AngularJS 2.0).
And since the new version, released in September 2016, was written in TypeScript and differed from the original one, it was renamed as Angular.&nbsp;&nbsp;
<h3 dir="ltr" style="text-align: justify;">JavaScript or TypeScript?</h3>
As you already understood, AngularJS is a JS-based framework that greatly simplifies the process of creating web resources. The fact is that almost any web developer (possessing JS knowledge at least at the basic level) can use AngularJS in his work.
Angular, on the other hand, is written in TypeScript, which, although derived from JS, has its own distinctive features. In particular, TypeScript hasn't abandoned the inherent concepts of object-oriented languages. This approach makes it much easier to write complex programs; also, it's more convenient to maintain, scale, and test them.

</div>
Now let's move on to our example. During development, we, surely, have to deal with various modal dialogs (and non-modal dialogs). And sometimes we may encounter certain difficulties. Trying to solve such problems often leads to new web solutions. And you, too, can take advantage of the results of our efforts.
Let&rsquo;s take a closer look at the issue.
<h2 dir="ltr" style="text-align: justify;">Angular Dialog Box</h2>
Angular isn't a &ldquo;dead&rdquo; framework (figuratively speaking), developers continue to work hard on improving it by adding new features and elements to it. However, in some ways, its functionality differs from that offered by AngularJS. Among other things, let's pay closer attention to the dialog window (popup).
We propose to consider 2 popular ways to implement a dialog box, namely: <a href="https://github.com/shlomiassaf/angular2-modal" target="_blank" rel="nofollow noopener">angular2-modal</a> and <a href="https://github.com/pleerock/ngx-modal" target="_blank" rel="nofollow noopener">ngx-modal</a>. What can they do?
<h2 dir="ltr" style="text-align: justify;">What Can These Components Do?</h2>
<h3 dir="ltr" style="text-align: justify;">The ability to open a dialog box directly</h3>
Resort to these components to open the dialog boxes with the indicated template from the component you require.
The whole implementation process is extremely simple: import the service you need and call the appropriate method to perform the action. This is usually enough to open a dialog box directly. If not, use a base component to wrap your template, then call the Open function (using its link).
It looks as follows:
<pre><code class="language-javascript">//Option 1. Calling from the component



openDialog() {



&nbsp;&nbsp;&nbsp;this.dialog



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.body(&lsquo;&lt;h4&gt;My first dialog window&lt;/h4&gt;&rsquo;)



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.open();



}



//Option 2. Wrapping the dialog window in the base component



&lt;button (click)="myDialogWindow.open()"&gt;open dialog window&lt;/button&gt;



&lt;modal #myDialogWindow&gt;



&nbsp;&nbsp;&nbsp;&nbsp;&lt;!-- Your dialog window HTML code --&gt;



&lt;/modal&gt;</code></pre>
<h3 dir="ltr" style="text-align: justify;">Customization</h3>
It is logical to assume the components of the dialog window should offer some basic configuration to manage it. Here are just a couple of key examples:
<ul style="list-style-type: disc;">
<li dir="ltr" aria-level="1">
control of the size of the dialog box;
</li>
<li dir="ltr" aria-level="1">
button to close, hide, or open it;
</li>
<li dir="ltr" aria-level="1">
the chance to close the box by outside click;
</li>
<li dir="ltr" aria-level="1">
and so on.
</li>
</ul>
The purpose of all these configurations is to help you customize the dialog window to suit your needs.
It allows you to get a custom dialog box, which is a big advantage, isn't it?
<h2 dir="ltr" style="text-align: justify;">What Do These Components Lack?</h2>
Customizable Angular dialogs are a good thing, but you shouldn't forget about some of the disadvantages of these components, namely...
<h3 dir="ltr" style="text-align: justify;">Dialog boxes as dynamically created elements</h3>
As you already understood, some components require passing HTML templates to a specific function, while others serve to wrap the templates (as we wrote above).
Let&rsquo;s take a closer look at each case.
<ol style="list-style-type: decimal;">
<li dir="ltr" aria-level="1">
You insert the dialog into your HTML code when called. But you should bear in mind that it&rsquo;s not about a single (separate) element, and this fact goes against the concept of Angular apps.
</li>
<li dir="ltr" aria-level="1">
So, you used the base dialog window component as a wrapper for the template, but thereby you increased the file HTML size (since the template immediately penetrates the code). As a result, the web page takes longer to load, which annoys the user. In addition, there is the problem of resetting data (after all, the dialog is just hidden, not deleted after it has been closed).
</li>
</ol>
By wisely using the capabilities of Angular, you get the chance to dynamically insert elements into templates of other components. That is, a component instance is being created (and drawn) ONLY when the function has been called. And it gets removed on close (which can be customized as desired)
<h3 dir="ltr" style="text-align: justify;">Data transmission</h3>
Besides, no one would mind the ability to transmit various kinds of data to the dialog box. Say, how about lines, arrays, objects, and more?
<h2 dir="ltr" style="text-align: justify;">Ng2-dialog-window: Our Improved Solution</h2>
Our team successfully applied ng2-dialog-window (1st version); what's more, we managed to reduce the impact of the above-described disadvantages. And we're not going to relax our efforts! We'll keep working on bettering the solution.
<h3 dir="ltr" style="text-align: justify;">A quick guide to using ng2-dialog-window</h3>
1) First, decide from which component you are going to call the dialog box. Connect Ng2DialogWindowService to it and call the openModal method.&nbsp;
<pre><code class="language-javascript">constructor( private dialog: Ng2DialogWindowService, private viewContainer: ViewContainerRef) {



}



openModal() {



&nbsp;&nbsp;&nbsp;&nbsp;this.dialog.openModal(this.viewContainer, {component: YourDialogWindowComponent})



}</code></pre>
2) Add your dialog window component to the entryComponents​
<pre><code class="language-javascript">@NgModule({



&nbsp;&nbsp;&nbsp;//...



&nbsp;&nbsp;&nbsp;entryComponents: [



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;YourDialogWindowComponent



&nbsp;&nbsp;&nbsp;],



})</code></pre>
3) Now is the time to extend your component from Ng2DialogWindowComponent. Such a step would help you inherit base methods; therefore, you'll be able to use ng2-dialog-window-component tag to wrap the template.
P.S. We guess Angular doesn't have an easier way to inherit other components styles. Let us know if you consider us wrong (of course the situation could have changed for the better since this article was written).
<pre><code class="language-javascript">@Component({



&nbsp;&nbsp;&nbsp;&nbsp;selector: 'my-dialog-window',



&nbsp;&nbsp;&nbsp;&nbsp;template: '&lt;ng2-dialog-window-component&gt;&lt;!-- Body of dialog window --&gt;&lt;/ng2-dialog-window-component&gt;'



})



export class YourDialogWindowComponent extends Ng2DialogWindowComponent {



}</code></pre>

Popular Angular Dialog Windows and How We Tried to Improve Them

How can you save your time when developing a rails application? The answer is to use application templates you can build on the basis of simple template our team has recently created. We believe it can be really helpful in your every-day development practice.
<h2 dir="ltr" style="text-align: justify;">What is Rails Application Template?</h2>
Rails Application Template is a basic template for creating Ruby-on-Rails applications. It simplifies the development process when starting a new project and saves your time which can be spent more wisely. Thereby, you can omit all the routine actions and skip to the stages that require you to be more creative and apply your professional skills.
<h2 dir="ltr" style="text-align: justify;">Advantages:</h2>
<ul dir="ltr">
<li style="text-align: justify;">Time-saving. As we've already mentioned, our template saves you from unnecessary work and allows to switch your attention to more interesting tasks.</li>
<li style="text-align: justify;">Easy process of configuring rails gems. You can easily configure our template to fit your needs and add new gems (below, we're describing this process in more details).</li>
<li style="text-align: justify;">Ease of use. This template is really easy-to-use and can be enhanced for your own requirements in a straightforward manner.</li>
</ul>
<h2 dir="ltr" style="text-align: justify;">How to use</h2>
First of all, you should download or clone the template. Then set your ruby version and gemset:
<pre><code class="language-javascript">$ rvm use 2.3.0@myapp --create</code></pre>
When it&rsquo;s done, install rails gem for the gemset:
<pre><code class="language-javascript">$ gem install rails -v 'your_rails_version'</code></pre>
Now you&rsquo;re ready to use our template when creating your application:
<pre><code class="language-javascript">$ rails new myapp -m /path/to/template/bootstrap.rb</code></pre>
That&rsquo;s all! It was quite easy, right? And now you can enjoy your application!
<h2 dir="ltr" style="text-align: justify;">Customization</h2>
The template uses config.yml file for installing and configuring rails gems and other stuff. Below you can find a list of statements able to help you customize your own template.
1) The configuration file consists of several blocks dividing the application generation process into some logic parts.
<pre><code class="language-javascript">rvm: ...
testing: ...
documentation: ...
deploy: ...</code></pre>
2) The main part of each block is gems. So if you want to have more gems in your project just add a new block with a name that corresponds with your appropriate gems block or add your gems to any existing block.
<pre><code class="language-javascript">testing:
&nbsp;&nbsp;gems:
&nbsp;&nbsp;&nbsp;&nbsp;faker: true
&nbsp;&nbsp;&nbsp;&nbsp;rspec-rails:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;group: test, development
&nbsp;&nbsp;&nbsp;&nbsp;factory_girl_rails:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;version: ~&gt; 4.8
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;group: test, development</code></pre>
You can use a true value for a gem that in this case will be added to Gemfile as gem 'faker'
You can also pass version and/or group params and they will be used in Gemfile:
<pre><code class="language-javascript">gem 'factory_girl_rails', '~&gt; 4.8', group: [:test, :development]</code></pre>
3) Each block can run its own runner from runners folder if one exists. There you can put any code you want to execute, i.e.
<pre><code class="language-javascript">create_file '.ruby-version', RUBY_VERSION
create_file '.ruby-gemset', app_name
file '.rvmrc', "rvm use #{RUBY_VERSION}@#{app_name}"</code></pre>
4) If you want to perform some actions after gem is added, i.e. run rails generate rspec:install, put callback to the runner and it will be executed when you need. By convention, callback name depends on gem name and should look like:
<pre><code class="language-javascript">"#{your_gem_name.gsub('-', '_')}_callback"</code></pre>
So the full configuration for rspec-rails looks like:
<pre><code class="language-javascript"># config.yml
testing:
&nbsp;gems:
&nbsp;&nbsp;&nbsp;rspec-rails:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;group: test, development

# runners/testing.rb
def rspec_rails_callback
&nbsp;generate('rspec:install')
end</code></pre>

Rails Application Template. A basic template for creating Ruby-on-Rails applications

Rails Application Template for Creating Ruby-on-Rails Apps

This is the third part of the article series about our experience of using and adapting the VIPER architecture. In the <a href="https://agilie.com/blog/the-use-and-adaptation-of-the-viper-architecture-on-our-own-example-of-development-part-1">first part</a>, we had discussed the basics of using and adapting the architecture of the VIPER and <a href="https://agilie.com/blog/the-use-and-adaptation-of-the-viper-architecture-on-our-own-example-of-development-part-2">last time</a> we talked about structuring and creating project skeleton for VIPER. It's high time to talk about creating a module in terms of VIPER architecture
Here goes!
Probably, the most time-consuming part of using VIPER architecture is creating lots of additional files and classes. So let&rsquo;s sort it out and first of all see what we should create and why we need it.
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631759243.png" alt="" width="512" height="276" />
<h2 dir="ltr" style="text-align: justify;">1. Factory</h2>
The factory is a class responsible for creating a module with parameters (any data needed to be transferred to module we&rsquo;re opening) and completion (a module which opens current one and which has to decide what to do with it). The controller should conform to ModuleInputProtocol.&nbsp;&nbsp;
<pre><code class="language-javascript">&nbsp;func createModule(arguments: NamedValuesType, completion: ModuleCompletionHandler?) -&gt; UIViewController {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let storyboard = UIStoryboard(name: storyboardId, bundle: nil)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let controller = storyboard.instantiateViewController(withIdentifier: initialControllerID)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let moduleInput = controller as? ModuleInputProtocol

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if let moduleInput = moduleInput {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;moduleInput.setupInitialState(withArguments: arguments, completion: completion)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} else {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;fatalError("\(initialControllerID) moduleInput == nil")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return controller

&nbsp;&nbsp;&nbsp;}</code></pre>
It should also define storyboardId and initialControllerID
<pre><code class="language-javascript">&nbsp;&nbsp;&nbsp;// MARK:

&nbsp;&nbsp;&nbsp;let storyboardId = "StartScreen"

&nbsp;&nbsp;&nbsp;let initialControllerID = "StartScreenViewController"</code></pre>
<h2 dir="ltr" style="text-align: justify;">2. Storyboard</h2>
Storyboard is a very important class because all the UI elements should be placed here. Moreover, there&rsquo;re a few requirements for storyboard.
<ul style="list-style-type: disc;">
<li dir="ltr">
Initial storyboard controller should have storyboard id, defined in Factory
</li>
</ul>
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631773209.png" alt="" width="512" height="181" />
<ul style="list-style-type: disc;">
<li dir="ltr">
Storyboard has to contain an object with custom class name acting as module initializer (e.g StartScreenModuleInitializer)
</li>
</ul>
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631786425.png" alt="" width="512" height="159" />
&nbsp;
<h2 dir="ltr" style="text-align: justify;">3. View</h2>
One of the VIPER module parts is the View which means not only UIView but also all the presentation layers including View, ViewController, DataSources, Delegates, Adapters etc. One more important moment is the interaction between View and other parts of the module, namely the Presenter.
And, of course, we should define input and output protocols. So input protocol (ViewInput) defines methods by which the Presenter calls the View and output protocol (ViewOutput) defines how the View calls the Presenter.
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631798746.png" alt="" width="512" height="140" />
<h2 style="text-align: justify;">4. Presenter</h2>
This part acts as a mediator between View and the data layer. It communicates with View in two ways using ViewInput and ViewOutput protocols. And the main task is to process the data retrieved and then assign it to the View.
<h2 style="text-align: justify;">5. Interactor</h2>
The interactor is a class responsible for communication between VIPER module and the external &ldquo;world&rdquo;. In this case, Presenter asks for data by InteractorInput protocol. We don&rsquo;t use InteractorOutput here to transfer data to Presenter for asynchronous operations (e.g API calls) because we usually use PromiseKit for them. We will show how we use it in the final part.
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631811810.png" alt="" width="512" height="108" />
<h2 style="text-align: justify;">6. Configurator</h2>
This part of VIPER module is responsible for initial module setup and consists of two parts
<ul style="list-style-type: disc;">
<li dir="ltr">
Initializer (ModuleInitializer).
</li>
</ul>
<pre><code class="language-javascript">class StartScreenModuleInitializer: NSObject {

&nbsp;&nbsp;&nbsp;//Connect with object on storyboard

&nbsp;&nbsp;&nbsp;@IBOutlet weak var startscreenViewController: StartScreenViewController!



&nbsp;&nbsp;&nbsp;override func awakeFromNib() {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let configurator = StartScreenModuleConfigurator()

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;configurator.configureModuleForViewInput(viewInput: startscreenViewController)

&nbsp;&nbsp;&nbsp;}

}</code></pre>
StartScreenViewController should be linked to its outlet in storyboard. After loading all UI elements from nib configurator is called to setup all module units (View, Presenter, Interactor).
<ul style="list-style-type: disc;">
<li dir="ltr">
Configurator is the main setup unit.
</li>
</ul>
<pre><code class="language-javascript">class StartScreenModuleConfigurator {



&nbsp;&nbsp;&nbsp;func configureModuleForViewInput&lt;UIViewController&gt;(viewInput: UIViewController) {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if let viewController = viewInput as? StartScreenViewController {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;configure(viewController)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}

&nbsp;&nbsp;&nbsp;}



&nbsp;&nbsp;&nbsp;private func configure(_ viewController: StartScreenViewController) {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let presenter = StartScreenPresenter()

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;presenter.view = viewController

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let interactor = StartScreenInteractor()

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;interactor.weatherService = ServicesAssembly.shared.weatherService

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;presenter.interactor = interactor

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;presenter.router = PresentationAssembly.shared.router

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;viewController.output = presenter

&nbsp;&nbsp;&nbsp;}

}</code></pre>
As we can see, it creates Presenter and Interactor, assigning all required services to them and connecting them together. The presenter has a reference to Interactor while View refers to Presenter.
Now module is ready to be shown on the screen.
&nbsp;
It looks clear enough, but in reality, it requires a lot of work to create the same files for each module. And on the other hand, too much time is spent for forming VIPER module, whereas similar screens could be easily created using MVC or MVP. Is it possible to find a solution to this problem? Maybe some script could simplify the whole process by doing all this work for us?
Luckily, there is a great solution, namely - <a href="https://github.com/strongself/Generamba">Generamba</a> (created by Rambler Digital Solutions), which allows defining folder structure, files, and the code they contain. So, by using easy command we receive all these files generated automatically! And the only thing we need to do is to implement business logic to the module. Quite easy, right?
Let&rsquo;s take a look at <a href="https://github.com/strongself/Generamba">Generamba</a> in more details.
<h2 style="text-align: justify;">Generamba in practice</h2>
The first step would be Generamba installation. You can achieve this by using &ldquo;gem install generamba&rdquo; command that requires Ruby 2.2 version.
The next step is to set up Generamba in the project. Run &ldquo;<a href="https://github.com/strongself/Generamba/wiki/Available-Commands">generamba setup</a>&rdquo; command in project root to create <a href="https://github.com/strongself/Generamba/wiki/Rambafile-Structure">Rambafile</a> and add required information about project and author such as author name, company name, target name, etc. It&rsquo;s necessary to properly add new files to the project. And don&rsquo;t worry, this file can be modified any time you want.
Now you should add all the templates you&rsquo;re going to use in the project to the Rambafile. For instance:
<pre><code class="language-javascript">templates:
- {name: rviper_controller}
- {name: local_template_name, local: 'absolute/file/path'}
- {name: remote_template_name, git: 'https://github.com/igrekde/remote_template'}</code></pre>
So you can see three different templates:
<ul dir="ltr">
<li style="text-align: justify;">rviper_controller is a shared template. You can see full list <a href="https://github.com/strongself/generamba-catalog">here</a></li>
<li style="text-align: justify;">local_template_name is template located on your computer locally</li>
<li style="text-align: justify;">remote_template_name is a link to template located on the web</li>
</ul>
Then run &ldquo;<a href="https://github.com/strongself/Generamba/wiki/Available-Commands">generamba template install</a>&rdquo; command to install all templates which will be downloaded and added to &ldquo;Templates&rdquo; folder.
And now it&rsquo;s time for the last step that includes the module generating process. Run &ldquo;<a href="https://github.com/strongself/Generamba/wiki/Available-Commands">generamba gen [Module name] [Template name]</a>&rdquo; to generate all files specified in the template.
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631829140.png" alt="" width="512" height="207" />
The script was executed successfully and now we can see what has been created:
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631840959.png" alt="" width="512" height="197" />
It's a great result! We used our remote template with name <a href="https://github.com/agilie/swift_viper_template">swift_viper_template</a> and got all files generated without any difficulties!

In the <a href="https://agilie.com/blog/the-use-and-adaptation-of-the-viper-architecture-on-our-own-example-of-development-part-1" target="_blank" rel="nofollow noopener">first part</a>, we discussed the basics, now it's time to talk about structuring and creating project skeleton for VIPER.
<h2 dir="ltr" style="text-align: justify;">General Info</h2>
To simplify the development process and make it more clear, we usually separate classes into different folders and groups such as Constants, Extensions, Services, Models, Presentation. In addition, Extensions could be divided into smaller groups like UIExtensions, Animations, etc., and Models - into DTO, Business, etc. As for Services, we will discuss them below.
As you can see, there is nothing particularly difficult about these groups, but let's take a closer look at the project structure in terms of VIPER architecture.
<h2 dir="ltr" style="text-align: justify;">1. Services</h2>
For the code clarity, services are better to be divided into several groups like Infrastructure and Business. The first group should contain essential services (API service, Settings service, etc), and the second one consists of all services working with data and business logic.
And there is also the main class called Service Assembly that is a shared instance comprising all services in the app e.g. API service, Settings service, business services, etc.
<pre><code class="language-javascript">protocol ServicesAssemblyProtocol {

&nbsp;&nbsp;&nbsp;var application: UIApplication { get }

&nbsp;&nbsp;&nbsp;var apiService: APIService { get }

&nbsp;&nbsp;&nbsp;var weatherService: WeatherService { get }

}</code></pre>
All services are initialized with the required instances of other ones. For example, UserService might need access to API or Database services.
<pre><code class="language-javascript">class ServicesAssemblyImpl: ServicesAssemblyProtocol {

&nbsp;&nbsp;&nbsp;let application: UIApplication

&nbsp;&nbsp;&nbsp;let apiService: APIService

&nbsp;&nbsp;&nbsp;let weatherService: WeatherService



&nbsp;&nbsp;&nbsp;init(application: UIApplication) {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;self.application = application

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;apiService = APIServiceImpl()

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;weatherService = WeatherServiceImpl(apiService: apiService)

}

}</code></pre>
All setup logic for services is generally implemented in AppDelegate since we might need it at the very start.
<pre><code class="language-javascript">&nbsp;&nbsp;&nbsp;func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -&gt; Bool {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Setup services

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ServicesAssembly.setup(application: application)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Setup everything else if needed

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return true

}</code></pre>
 <img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631576231.png" alt="" width="512" height="483" />
<h2 dir="ltr" style="text-align: justify;">2. Presentation</h2>
Presentation&nbsp;is a group with all layout logic inside. Let&rsquo;s examine its structure in depth.
PresentationAssembly is a shared class containing references to the presentation layer.
<pre><code class="language-javascript">protocol PresentationAssemblyProtocol {

&nbsp;&nbsp;&nbsp;var router: AppRouterProtocol! { get }

&nbsp;&nbsp;&nbsp;var whisper: InAppNotificationsProvider! { get }

}



class PresentationAssembly: PresentationAssemblyProtocol {

&nbsp;&nbsp;&nbsp;static let shared = PresentationAssembly()

&nbsp;&nbsp;&nbsp;var router: AppRouterProtocol!

&nbsp;&nbsp;&nbsp;var whisper: InAppNotificationsProvider!

&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;func setup(withNavigation navigation: UINavigationController, modules: Array&lt;ModuleFactoryProtocol&gt;, urlScheme: String, services: ServicesAssemblyProtocol) {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;router = AppRouterImpl(withNavigation: navigation, modules: modules, urlScheme: urlScheme)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;whisper = InAppNotificationsProviderImpl(withNavigation: navigation)

}

}</code></pre>
&nbsp;
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631589098.png" alt="" width="512" height="278" />
Let&rsquo;s consider Application root more carefully.
<h2 dir="ltr" style="text-align: justify;">Application root</h2>
Application root is an entry point to the app. It is called by AppDelegate and responsible for launching an application and all configuration needed before that moment.&nbsp;
<pre><code class="language-javascript">&nbsp;&nbsp;func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -&gt; Bool {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Setup here &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Start application

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;appRoot = ApplicationRoot(withNavigation: navigationController)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;appRoot.start()

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return true

}</code></pre>
It sets up every necessary service, router, presentation stuff and chooses a module to show first (log in or main screen, for instance). Application root also contains all existing modules inside in order to know about each of them to be able to create it.
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631600777.png" alt="" width="512" height="177" />
<pre><code class="language-javascript">class ApplicationRoot: NSObject {

&nbsp;&nbsp;&nbsp;let modules : Array&lt;ModuleFactoryProtocol&gt; = [

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;StartScreenFactory.shared,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;DetailsScreenFactory.shared

&nbsp;&nbsp;&nbsp;]



&nbsp;&nbsp;&nbsp;// MARK:

&nbsp;&nbsp;&nbsp;fileprivate let router: AppRouterProtocol

&nbsp;&nbsp;&nbsp;fileprivate let whisper: InAppNotificationsProvider



&nbsp;&nbsp;&nbsp;init(withNavigation navigation: UINavigationController) {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let services = &nbsp;ServicesAssembly.shared

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let presentation = PresentationAssembly.shared

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;presentation.setup(withNavigation: navigation, modules: modules, urlScheme: "viper", services: services)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;router = presentation.router

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;whisper = presentation.whisper &nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;super.init()

}



&nbsp;&nbsp;&nbsp;func start() {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;let urn = StartScreenFactory.shared.moduleURN

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;router.pushModule(byUrn: urn, animated: true, completion: { (_) in

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//completion

})

}

}</code></pre>
<h2 dir="ltr" style="text-align: justify;">Application router</h2>
AppRouter contains all routing logic. It is created by Application root and responsible for navigation between modules e.g. push/pop or present/dismiss etc.
<pre><code class="language-javascript">protocol AppRouterProtocol {

&nbsp;&nbsp;&nbsp;var navigationController: UINavigationController { get }

&nbsp;&nbsp;&nbsp;func pushModule(byUrn urn: String, animated: Bool, completion: ModuleCompletionHandler?) &nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;func presentModule(byUrn urn: String, animated: Bool, completion: ModuleCompletionHandler?) &nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;func popToViewController(_ controller: UIViewController, animated: Bool)

&nbsp;&nbsp;&nbsp;func dismissCurrentController(animated: Bool)

}</code></pre>
It&rsquo;s global in general but can be moved to each module or added to some of them depending on the complexity if we want so.
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631615470.png" alt="" width="512" height="314" />
As you can see Routing group also contains ModuleFactoryProtocol
<pre><code class="language-javascript">protocol ModuleFactoryProtocol {

&nbsp;&nbsp;&nbsp;/**

&nbsp;&nbsp;&nbsp;&nbsp;* Module URN ( ex. profile:{userID} )

&nbsp;&nbsp;&nbsp;&nbsp;*/

&nbsp;&nbsp;&nbsp;var moduleURN: String { get } &nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;/**

&nbsp;&nbsp;&nbsp;&nbsp;* Create module with arguments

&nbsp;&nbsp;&nbsp;&nbsp;* Returns module root UIViewController, must implement ModuleInputProtocol.

&nbsp;&nbsp;&nbsp;&nbsp;*/

&nbsp;&nbsp;&nbsp;func createModule(arguments: NamedValuesType, completion: ModuleCompletionHandler?) -&gt; UIViewController

}</code></pre>
which defines the way how new module can be created and ModuleInputProtocol
<pre><code class="language-javascript">protocol ModuleInputProtocol {

&nbsp;&nbsp;&nbsp;&nbsp;/**

&nbsp;&nbsp;&nbsp;&nbsp;* Configure module with arguments.

&nbsp;&nbsp;&nbsp;&nbsp;* Calls form Module factory

&nbsp;&nbsp;&nbsp;&nbsp;*/

&nbsp;&nbsp;&nbsp;func setupInitialState(withArguments args: NamedValuesType, completion: ModuleCompletionHandler?)

}</code></pre>
defines the way module could be configured with additional parameters.
Presentation group also contains any additional groups required by the app. For example, InAppNotifications (alerts, toast etc), StyleKit (responsible for styling application if necessary), SocialServices (Facebook, Twitter, etc), and lots of other logic your app may need.
<h2 dir="ltr" style="text-align: justify;">Views</h2>
Views is created for keeping all the custom layouts which are placed just here. Besides, it can include the following groups inside such as Layouts, Cells, Collections, etc.
<h2 dir="ltr" style="text-align: justify;">User stories</h2>
This part consists of all your screens and UI logic and contains every VIPER module that is located here and should include: Factory, Configurator, View, Presenter, and Interactor. 
We will describe the module structure in the next article and right now just say that it may have storyboard or xib file inside if needed.
<img style="border: none;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631628252.png" alt="" width="504" height="512" />
So, to conclude, to simplify finding the specific class or service let&rsquo;s mention that the structure of the project is extremely clear. In addition, it&rsquo;s good practice to keep the group and folder structure the same way. 
In the next - third - part of our article we'll tell you about creating a module in terms of VIPER architecture: units, their responsibilities, etc.

Structuring and creating project skeleton for VIPER architecture

The use and adaptation of the VIPER architecture on our own example of development, part 2

In this article, we want to share with you our experience of using and adapting the architecture of the Viper by describing our own example of development. And today we're going to discuss the basics&hellip; &nbsp;
Many developers face an issue when code becomes hard to read, debug and fix bugs. Classes become huge together with adding features and development turns to infinite &ldquo;bugfixing&rdquo;. That&rsquo;s why it&rsquo;s important to choose proper software architecture before developing an application, otherwise, it will consume much time to maintain and improve. As a result, it will help to save time and efforts, so proper architecture is the first step to success!
<h2 style="text-align: justify;">Perfect architecture</h2>
Quality architecture should meet the following requirements:
<ol dir="ltr">
<li style="text-align: justify;">The effectiveness of performing the assigned tasks. If designed architecture performs the tasks poorly and doesn't fit into the requirements of functionality, stability, performance, and development time, it can hardly be called a good one.</li>
<li style="text-align: justify;">Well readable and understandable code. First and foremost, a code should be clear and properly structured.</li>
<li style="text-align: justify;">The scalability and flexibility of the system. A good architecture allows you to painlessly add new entities and functions, as well as make changes to existing functionality.</li>
</ol>
However, there is no reason to reinvent the wheel and spend a lot of time developing a completely unique architectural pattern. It's much easier to use the existing one.
There&rsquo;re several most famous architectures named MVC, MVP, MVVM, VIPER. Let&rsquo;s probe deep into each of them.
<h2 dir="ltr" style="text-align: justify;">MVC (Model View Controller)</h2>
MVC is the most simple architecture Apple recommends.
<img style="border: none; width: 512px; height: 208px;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631376053.png" alt="^56BDEBB44AF88BAB8B39A1A9F8FC649A23FC487FB5D45024D5^pimgpsh_fullsize_distr.png" />
The basic idea of MVC architecture is to split up all the elements (fragments) of the code into three separate units: the Model (domain data or a data access layer), the View (user interface) and the Controller (interface between Model and View). MVC allows each block to be controlled independently of the two others, and it greatly simplifies and systematizes the development process.
MVC implies that the Model manipulates data and provides it to the Controller that renders the View. And the View remains stateless just displaying data of the Model to a user.
However, the described model may not work perfectly in all conditions. And in reality, the View and the Controller often become a single unit looking like this:
<img style="border: none; width: 512px; height: 61px;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631386327.png" alt="2.png" />
So, ViewController transforms into the Massive View Controller forced to handle almost all the processes itself. And the main task for developers, in this case, is to offload it.
<div>
<h2 dir="ltr" style="text-align: justify;">MVP (Model View Presenter)</h2>
It turned out that in some cases MVC architecture is not working as effectively as one expects (for the reasons described above). So there was MVP pattern designed, having become a bit improved version of MVC. 
The difference between MVC and MVP is the Presenter acting as the mediator between the View (actually ViewController) and the Model. The Presenter significantly unloads the ViewController by moving business logic to the Presenter, so the ViewController is only responsible for the layout and its lifecycle.
<img style="border: none; width: 512px; height: 199px;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631396862.png" alt="" />
This architecture makes it easier to mock the View, the Presenter and the Model that leads to better testability of the code which is an obvious advantage of MVP.
<h2 dir="ltr" style="text-align: justify;">MVVM (Model View ViewModel) </h2>
Another popular pattern is MVVM (Model View ViewModel). It looks similar to MVP architecture, but instead Presenter it has ViewModel between the View (view controller) and the Model (data).
<img style="border: none; width: 512px; height: 43px;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631408723.png" alt="3r.png" />
The important difference of this model from the MVP is that ViewModel doesn&rsquo;t refer to View, it works directly with model updating it with user interactions from View and receives updates from Model updating only itself (not View). View can receive updates using observer if needed. So ViewModel prepares the data for View that unloads controller.
<div>
<h2 dir="ltr" style="text-align: justify;">VIPER</h2>
The last architecture we will talk about is VIPER. It&rsquo;s a very effective architecture pattern, in fact, the first one that cares about navigation (routing) between modules.
It consists of 5 parts: View, Presenter, Interactor, Entity, Router.
<ul dir="ltr">
<li style="text-align: justify;">The view is the ViewController. The View&rsquo;s waiting for the Presenter to transmit the content and display it to a user; it never requests the data from the Presenter.</li>
<li style="text-align: justify;">Presenter prepares data for the View. It gathers data from user interactions and can send requests to the Interactor. The Presenter also gets results from the Interactor and convert the results to a state being most effective to display on the View.</li>
<li style="text-align: justify;">Interactor (a new unit) contains the business logic and networking for managing objects (Entity) to perform a specific task.</li>
<li style="text-align: justify;">Entity is the objects managed by the Interactor. So it&rsquo;s actually a model.</li>
<li style="text-align: justify;">Router (another new unit) is responsible for segues between modules.</li>
<li style="text-align: justify;">Data Store (e.g., web service, database) provides the Entity to the Interactor. Applying its business logic, Interactor selects the Entity from the data store, manages it and then returns it in an updated form back to the datastore.</li>
</ul>
<img style="border: none; width: 512px; height: 196px;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631418693.png" alt="4.png" />
VIPER module is a user story that can be represented either as one screen or as a whole story. The good example is a registration flow consisting of several screens such as SignUp, Confirmation, etc.
Each module being an independent part requires an additional unit able to manage the entire process. This role is played by the Configurator which task is not only to create a module but also provide it with all necessary Services and information.
<h2 dir="ltr" style="text-align: justify;">Improving and Simplifying VIPER at the same time</h2>
VIPER architecture was reliable and usable from the outset, but <a href="https://github.com/strongself/The-Book-of-VIPER" target="_blank" rel="nofollow noopener">Rambler Digital Solutions</a> has improved and simplified it even more. Let&rsquo;s take a look at the main changes:
<ol dir="ltr">
<li style="text-align: justify;">Assembly functions which Wireframe was responsible for are moved to Configurator now. So, after this modification, Wireframe is in charge of Routing and nothing else.</li>
<li style="text-align: justify;">The router has become global</li>
<li style="text-align: justify;">All data transfer is executed according to ModuleInput and ModuleOutput protocols</li>
<li style="text-align: justify;">View is not only ViewController now; it acts as a presentation layer containing several parts (View, DataSource&rsquo;s. Delegate&rsquo;s, etc.)</li>
<li style="text-align: justify;">A new service layer has been added to a module with dependency injection into interactor. Thanks to this improvement a module interacts just with required services (they make networking, storing, collecting, etc.).</li>
</ol>
Thus, the VIPER is quite a useful architectural system, allowing to distinguish all of the logic, so that every class performs only actions it is responsible for.
<img style="border: none; width: 512px; height: 240px;" src="https://d12zh9bqbty5wp.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1676631429726.png" alt="6.png" />

The rise of crypto wallets represents&ensp;a significant innovation in fintech. Those wallets can be very useful for businesses because, with them, many people can have access to funds depending on roles and permissions.
Depending on the type, cryptocurrency wallets also help in managing digital assets and allow businesses or individuals to control funds without banking, as they retain the full autonomy of&ensp;funds, or even trade assets without manual transfers. In this article, we are going to see what is the difference between a custodial and non-custodial wallet.

<h2 dir="ltr" style="text-align: justify;">Foreword: The Essence of Private Keys</h2>
Hold on! Why is it important to discuss the private key and how it comes with the custodial and non-custodial wallets? Let&rsquo;s define this cryptographic element and analyze its functions and importance for crypto wallets.&nbsp;
The crypto wallet generates a private key, which represents an alphanumeric code consisting of a large string of letters and numbers. The primary functions of a private key include enabling the users to authorize transactions and prove ownership of their assets.
This alphanumeric cipher matters to any crypto wallet type as it generates a digital signature. A private key is used to sign the transaction, which is transmitted to the blockchain, but prior to being added to the block, it requires verification. The computers operating the blockchain check the user&rsquo;s public key to verify the digital signature, and if it is correct the transaction is approved and recorded permanently on the blockchain.&nbsp;
The private and public keys are paired, which ensures the transaction&rsquo;s security due to the resistance to tampering and the impossibility of making any changes on the block. Hence, private keys are central elements of a crypto wallet, so let&rsquo;s discuss their essence in custodial and non-custodial wallets.&nbsp;
<h2 dir="ltr" style="text-align: justify;">What Is a Custodial Wallet?</h2>
The custodial wallet meaning can be defined as a wallet in which a third party, such as an exchange or bank, holds the private keys of the users. This means that the client is not in full control of their funds, as they rely on the custodian who secures and manages their transactions.&nbsp;
There are the following features of the custodial wallets:
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Simplified Usability
</li>
</ul>
The custodial wallets represent an opportunity for beginners to trade their crypto assets without managing private keys.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Options for Account Recovery
</li>
</ul>
If users lose access to their accounts, they will be able to recover their funds as the custodian holds their private keys on the centralized server. The users will only have to verify their identity.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Support Opportunities
</li>
</ul>
A central unity manages the client&rsquo;s wallet, providing them with support like undoing the transaction.
Some of the best custodial wallets to consider are: Coinbase, Gemini, BitMex, BitGo, Binance, and Bitfinex.
<h2 dir="ltr" style="text-align: justify;">What Is a Non-Custodial Wallet?</h2>
When analyzing the non-custodial vs custodial wallet, the first one provides clients with full ownership of their private keys and funds, respectively. This autonomy defines the non-custodial wallet meaning that no third party will handle the user&rsquo;s funds and operations. This excludes issues like account freezing and withdrawal restrictions. There are the following distinctive features of the non-custodial wallets:
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
User&rsquo;s Full Ownership
</li>
</ul>
The non-custodial wallets function within the decentralized ecosystem, meaning that no centralized unity will manage the wallet.
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Direct Blockchain Interaction
</li>
</ul>
A non-custodial wallet does not require an intermediary; transactions occur directly on the blockchain.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Increased Privacy
</li>
</ul>
The users don&rsquo;t have to abide by the Know Your Customer policy and verify their identity in the non-custodial wallet. This crypto wallet type preserves pseudoanonimity.

<h2 dir="ltr" style="text-align: justify;">Difference Between Custodial and Non-Custodial Wallet</h2>
Based on the aforementioned analysis of two crypto wallet types, their meaning, advantages, and disadvantages, it would be essential to provide a short summative recap, as well as additional details on the differences between the custodial wallet vs non-custodial wallet, focusing on the following metrics.

The custodial wallet is less secure than its non-custodial counterpart, considering its vulnerability to cyberattacks. Hackers can attack the centralized servers and obtain access to multiple accounts.
Credential harvesting is a phishing type of cyberattack which aims to steal a user&rsquo;s login and password so that the attacker can access their account. The attackers send the falsified site links, almost identical to the real ones, via SMS or email, so by entering their credentials, the victim provides them with access to their funds.&nbsp;
<h4 dir="ltr" style="text-align: justify;">Non-Custodial Wallet</h4>
The non-custodial wallets depend on the private keys owned by the users, which decreases the risks of theft. Nevertheless, attackers can obtain the key due to malware attacks, which can infect the computer or smartphone as in the case of clipboard hijacking malware attack.&nbsp;
The malware functions, so to say, silently in the device, monitoring the clipboard. When the user copies the wallet address, the malware substitutes it with the attacker&rsquo;s one, so the victim sends them their funds unintentionally.&nbsp;
<h3 dir="ltr" style="text-align: justify;">Ownership of Private Keys</h3>
<h4 dir="ltr" style="text-align: justify;">Custodial Wallet</h4>
In the custodial wallet, it&rsquo;s the custodian&rsquo;s responsibility to hold the user&rsquo;s private keys, which limits the latter&rsquo;s control over their funds. This is one of the most significant disadvantages of the custodial wallets for the following reasons:
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Lack of Client&rsquo;s Full Ownership Over Their Finances.
</li>
</ul>
The client has access to accounts but relies heavily on the custodian&rsquo;s controls over the transaction&rsquo;s approval.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Withdrawal and Transaction Restrictions
</li>
</ul>
The custodian can delay or block the transaction based on governmental policies, which can limit the fund movement.&nbsp;
<h4 dir="ltr" style="text-align: justify;">Non-Custodial Wallet</h4>
In the non-custodial wallet, the user holds the private keys by themselves, which is simultaneously convenient and requires a decent level of responsibility not to lose them.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
No KYC Compliance
</li>
</ul>
The non-custodial wallet does not rely on the KYC policy, so the user doesn&rsquo;t have to verify their identity to proceed with the transactions, showing their full ownership over their funds.&nbsp;
<h3 dir="ltr" style="text-align: justify;">Ease of Use&nbsp;</h3>
<h4 dir="ltr" style="text-align: justify;">Custodial Wallet</h4>
Custodial wallets are easier to use as the client does not have to know the precise details of the exchange work. If the user wants to undo the operation, customer support can help with that.&nbsp;
<h4 dir="ltr" style="text-align: justify;">Non-Custodial Wallet</h4>
Non-custodial wallets require decent knowledge about the work of blockchain and smart contracts, as minor mistakes can lead to the loss of funds with no refund option, representing one of the core challenges of this wallet type.

<h2 dir="ltr" style="text-align: justify;">Choosing the Right&nbsp;Wallet&nbsp;for Your Business Needs</h2>
You might be interested in how to choose the right wallet type per business needs. It's time to discuss the most suitable cases to use custodial and non-custodial cryptocurrency wallets.
<h3 dir="ltr" style="text-align: justify;">Custodial Wallets</h3>
The custodial wallets are a valuable option for businesses that need an insured and regulated service. For instance, Greyscale, a leading crypto asset manager, utilizes Coinbase Custody, which improves its scalability and contributes to success due to alignment with NYC banking laws as the wallet is regulated by NYDFS, one of the most prominent financial regulators in the world.&nbsp;
<h3 dir="ltr" style="text-align: justify;">Non-Custodial Wallets</h3>
The non-custodial wallets are best suited for businesses that manage crypto without third-party integration, and those companies with DeFi projects and NFT platforms. For instance, Open Sea, a web3 marketplace for NFTs, applies Meta Mask, which improves its scalability and success by integrating Layer 2 support like Polygon network for lower fees and faster transactions.

<h2 dir="ltr" role="presentation">&nbsp;Myth 1: Blockchain and Bitcoin Are the Same</h2>
Among the most common myths about blockchain technology is the confusion between the blockchain and Bitcoin. Blockchain and Bitcoin were created simultaneously, so they are widely believed to be the same thing. However, we must understand that blockchain is a much broader term. It is the technology that created Bitcoin. While Bitcoin is indeed the first and most famous application of this technology, equating the two is like saying that Google is the Internet.
Blockchain is a decentralized digital ledger technology (DLT) that records transactions across multiple computers so that the records cannot be altered retroactively, without the alteration of all subsequent blocks and the consensus of the network.
This makes blockchain a naturally secure and transparent method of data and transaction recording.&nbsp;
Bitcoin is a type of digital currency based on blockchain technology and used for secure, anonymous, and decentralized financial transactions. The blockchain of Bitcoin acts as a public ledger for all the transactions in the Bitcoin network, thus, it is possible to transfer digital currency securely without the use of intermediaries like banks or governments.&nbsp;
Blockchain technology can be much broader than purely financial transactions. It can be used in different industries with various aims. Nowadays, many businesses are studying how <a href="https://agilie.com/blog/enterprise-blockchain-development-how-businesses-derive-benefits" target="_blank" rel="noopener">enterprise blockchain development</a> can improve their operations.

Here are a few examples:
Healthcare: Blockchain can guarantee the safety of medical records storage and sharing. Thus, they are only available to authorized personnel and patients and lead to quicker diagnosis and treatment.​
Financial Services: Blockchain is a viable solution for international payments, real-time settlements, and improving transaction transparency and security.
Digital Identity:&nbsp; Blockchain can correct identity theft and fraud by adding digital identities that cannot be changed. For example, Estonia's e-Residency program is the first of its kind, a government-issued digital identity that allows entrepreneurs from anywhere in the world to operate and conduct business online in the EU.
Real Estate: Blockchain can simplify property transactions such as sales, leasing, and financing by reducing paperwork and improving transparency.

<h2 dir="ltr">Myth 2: Blockchain Transactions Are Always Anonymous</h2>
A frequent mistake people make about blockchain technology is that it is automatically anonymous to its users. However, the truth is more nuanced. Blockchain transactions are not strictly anonymous but pseudonymous.
Pseudonymity means that a user's identity is not directly tied to their blockchain transactions but rather to a digital pseudonym, typically a public key or a blockchain address. These addresses are like a sequence of letters and numbers, giving privacy but not total anonymity.
In contrast, anonymity would mean that the transactions are entirely disconnected from any identity, even a pseudonym, making them untraceable to the user. Blockchain does not usually provide this level of anonymity because the transaction history of each blockchain address is visible to anyone who accesses the blockchain.
Most blockchains are open ledgers, meaning that all transactions are visible to anyone who wishes to view them. This level of transparency ensures that while users' identities are not directly exposed, their transaction histories and patterns can be analyzed.<span style="font-size: 11pt; font-family: Roboto, sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-alternates: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">

While basic blockchain transactions offer pseudonymity, several enhancements and tools can increase privacy:
1. Mixing Services: Services like CoinJoin allow multiple users to combine their transactions into a single transaction with multiple inputs and outputs. This mixing blurs the traceability of any single coin, making it more difficult to link wallets with identities.
2. Privacy-Focused Cryptocurrencies: Some cryptocurrencies, like Monero and Zcash, are designed specifically to enhance privacy. Monero uses ring signatures and stealth addresses to hide the transactions&rsquo; origins, amounts, and destinations. Zcash allows users to shield transactions completely through its zk-SNARKs technology, which enables transactions to be verified without revealing the sender, receiver, or amount.
3. Use of Multiple Addresses: Users can increase their privacy by using multiple wallets or addresses, dispersing their transactions across several points, which makes it more challenging to link them to a single identity.

<h2 dir="ltr">Myth 3: Blockchains Are Unhackable</h2>
The idea that blockchains are completely unhackable is a frequently held misconception that can cause a dangerous level of complacency in security measures. While blockchain technology does offer robust security features, it is not immune to vulnerabilities. Knowing the security features employed and the situations in which breaches happen is very important for anyone who wants to use blockchain for their business.
Blockchain technology secures data through several mechanisms:
Cryptography: Every transaction on a blockchain is secured using cryptographic algorithms, which ensure that data can neither be altered nor read without the appropriate cryptographic key.
Decentralization: By distributing copies of the ledger across a network, blockchain reduces the risk of a single point of failure that could compromise the entire system.
Consensus Protocols: Blockchains use various consensus mechanisms, like Proof of Work (PoW) or Proof of Stake (PoS), to agree on the validity of transactions. These protocols prevent a malicious actor from changing even a single aspect of the blockchain.
<a class="incut--wrap" style="transition-delay: 0s;" href="https://agilie.com/expertise/fintech/blockchain-software" target="_blank" rel="noopener" aria-label="incut"><img style="height: 344px; width: 778px;" src="https://d3pxw3l8cozu05.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1716281102044.png" width="100%" height="100%" />Learn more about our blockchain software development services.</a>
Despite these security measures, there are scenarios where blockchains can and have been compromised.
<h3 dir="ltr">Scenarios Under Which Breaches Have Occurred</h3>
51% Attacks: This type of attack happens when a single entity gains control of more than 50% of the network&rsquo;s mining hash rate or stake, allowing them to manipulate transactions and potentially double-spend coins.&nbsp;
Code Vulnerabilities: <a href="https://agilie.com/blog/secure-smart-contract-design-best-practices-in-solidity-programming" target="_blank" rel="noopener">Smart contracts</a>, which are self-executing contracts with the terms directly written into code, can contain vulnerabilities. One of the most famous incidents is the DAO attack on the Ethereum network. Hackers exploited a vulnerability in the DAO (Decentralized Autonomous Organization) smart contract code to siphon off one-third of the DAO&rsquo;s funds.
Phishing and Social Engineering: End-user security is often the weakest link in a blockchain system. Phishing attacks can allow attackers access to blockchain assets, bypassing network security measures, to steal private keys or wallet credentials.

Nowadays, blockchain reshapes the functionality of the fintech industry, invoking a significant interest in institutions that work with financial operations directly. We&rsquo;re talking about accounting, which starts integrating blockchain technology to its daily operations.&nbsp;
Accounting is a noticeable area for blockchain innovation due to the significant improvements it can present. Businesses experience growth of interest in secure financial operations. The elimination of a single-point failure and cryptographic encryption can reduce the dependency on the centralized intermediary and protect financial transactions by improving security and economizing protection costs simultaneously. The article analyzes what is blockchain used for in accounting and its benefits.
<h2 dir="ltr" style="text-align: justify;">How Blockchain Is Transforming Accounting</h2>
As a distributed and public ledger, blockchain benefits versatile fintech and business branches due to its possibility to record transactions that cannot be altered. The impact of blockchain in accounting is significant as it eliminates manipulations with records and minimizes human errors. We&rsquo;re going to focus on fraud prevention and error detection capabilities of blockchain in accounting.&nbsp;
<a class="incut--wrap" style="transition-property: all;" href="https://agilie.com/blog/the-role-of-cryptography-in-blockchain-security" target="_blank" rel="noopener" aria-label="incut"><img style="float: left;" src="https://d3pxw3l8cozu05.cloudfront.net/images/f9e66e179b6747ae54108f82f8ade8b3c25d76fd30afde6c395822c530196169-1739370419274.png" width="100%" height="100%" />In this article you can learn how cryptography makes blockchain safe and the consensus mechanisms its work is based on.</a>
<h3 dir="ltr" style="text-align: justify;">Fraud Prevention</h3>
Blockchain undermines the pain point of fraudulent actions through immutability and security.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Immutability
</li>
</ul>
As stated above, the transaction is recorded, while the record is immutable. This is important for accounting to fraud prevention because it makes it difficult for fraudsters to manipulate revenue or conceal expenses.
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Safety
</li>
</ul>
Authorized parties can access a real-time ledger, proving that blockchain can reduce the likelihood of fraudulent reporting. The auditors can cross-check the transactions in real-time, which greatly reduces the risk of any manipulations in the financial statements.
Moreover, with triple-entry accounting, the blockchain makes it hard&ensp;to commit double-entry fraud. Transactions are cryptographically linked and recorded in the distributed&ensp;ledger, making identifying fraudulent actions easier.
<h3 dir="ltr" style="text-align: justify;">Error Detection and Overcoming</h3>
Blockchain helps to identify common human-factor mistakes and helps overcome them via smart contracts and AI integration.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Human Errors within Data Entry
</li>
</ul>
Blockchain helps resolve issues like incorrect figures or duplicate entries. Multiple parties validate the transduction cryptographically prior to recording. Smart contracts will automate the transactions, minimizing human input.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Duplicate Transactions
</li>
</ul>
Blockchain can help prevent accidental duplication of invoices, expenses, or payroll payments based on the correct realization of smart contracts or transaction control systems. The chances of record duplication are reduced as each transaction gets a unique cryptographic signature. Blockchain&rsquo;s task is to ensure a real-time reconciliation by underlining the duplicate entries.&nbsp;
<ul style="text-align: justify;">
<li dir="ltr" aria-level="1">
Transaction Misclassification
</li>
</ul>
Another human error in accounting is assigning the wrong category for revenue, expenses, or&ensp;liabilities, which results in erroneous financial statements. Smart contracts and AI analyze transactions and mark inconsistencies, while the immutable ledger ensures proper classification.
<h2 dir="ltr" style="text-align: justify;">Key Benefits of Blockchain in Accounting</h2>
Accounting organizations can optimize their record processing, minimize fraud, and economize financial input by integrating blockchain technology. Let&rsquo;s analyze the advantages of blockchain in accounting into the following categories.
<h3 dir="ltr" style="text-align: justify;">Transparency</h3>
The blockchain works on the distributed ledger that instantly&ensp;records any transactions and displays them to authorized users. The immutable ledger eliminates the possibility of changes and is deleted once the finance-relevant operation is recorded. Finally, one of the key benefits blockchain brings to accounting is the absence of dependency on centralized units. All the required stakeholders and auditors are independent in verifying transactions.
<h3 dir="ltr" style="text-align: justify;">Security</h3>
Blockchain and accounting are intertwined based on security intensification. Now, let&rsquo;s analyze how exactly blockchain helps accounting improve the security of its operations.&nbsp;&nbsp;
Blockchain assists accounting services in preventing and reducing fraudulent activities due to the cryptographic security mechanisms that protect against unauthorized access. Another way of supporting safety in accounting is securing financial data through advanced cryptographic encryption. Blockchain can prevent unauthorized alterations in the transactions via the consensus mechanisms that verify and record those operations.&nbsp;
Finally, as in blockchain, there is no need to rely on a third party; decentralized storage minimizes the risks of cyberattacks. For instance, Deloitte relies on machine learning in blockchain that helps check, mark anomalies, and set a risk rate for the transaction.&nbsp;
Nevertheless, it is important to remember the existing threats of cyber attacks on the users&rsquo; non-custodial wallets, smart contracts, and network nodes. The intermediary can store data in a centralized server, making it vulnerable to a single-point attack, while in the blockchain, decentralized storage eliminates this single-point failure and reinforces tamper resistance, making the records immutable based on the blockchain hashing.&nbsp;
<h3 dir="ltr" style="text-align: justify;">Efficiency</h3>
Blockchain in accounting applies smart contracts that automate financial transactions. Manual intervention and processing are not required. The ledger facilitates real-time financial reporting, so&ensp;there are no delays in data processing. The distributed nature of the ledger allows auditors to determine if the transaction was legitimate. Overall, blockchain improves the efficiency of accounting services by minimizing the need for repeated data entry, which minimizes human errors.&nbsp;
<h3 dir="ltr" style="text-align: justify;">Cost Savings</h3>
Blockchain minimizes overhead and manual transaction processing by excluding the dependency on third parties and eliminating the need to perform manual audits.&nbsp;
Blockchain favorably affects compliance costs by ensuring automatic alignment with accounting regulations. Finally, blockchain minimizes costs associated with error corrections and fraud detection.&nbsp;
<h2 dir="ltr" style="text-align: justify;">How Can Blockchain Be Used in Accounting?</h2>
Indisputably, the organization specializing in accounting can benefit significantly from integrating a decentralized ledger due to improved security, optimized time, and efficiency in verifying and operating transactions. But what are the practical examples of blockchain in accounting? Let&rsquo;s clarify.
<h3 dir="ltr" style="text-align: justify;">Auditing and Assurance</h3>
Traditional accounting depended on third-party confirmations to check and verify whether the financial record was legitimate. Audits were time-consuming due to manual proceeding and verification. Blockchain functionality is based on the smart contract, which benefits audit compliance. It is possible to pre-program specific financial processes to follow audit rules automatically. Auditors don&rsquo;t have to wait for periodic reports. Instead, they can access data in real time.&nbsp;
<h3 dir="ltr" style="text-align: justify;">Tax Compliance</h3>
Traditional manual tax management faced the challenges of income misreporting or purposeful dedication, which led to tax evasion and non-compliance. Here on, tax audits can be time-consuming to complete.
Integrating blockchain into accounting can eliminate invoice falsification. Smart contracts can automate the process of invoice verification in real-time prior to processing the tax claim. However, the correctness of data depends on the source information checked by the accountants. The immutable ledger ensures no record can be altered, eliminating the manipulation of tax-relevant data. Finally, due to the integration with the API of tax offices, smart contracts can calculate and file tax automatically based on recorded transactions.&nbsp;
<h3 dir="ltr" style="text-align: justify;">Payroll Management</h3>
Payroll management encountered the dilemma of ghost employees who could divert and manipulate funds. Implementing blockchain technology in accounting can eliminate potential fraudulent actions in the following ways. Smart contracts can contribute to payroll automation by the automatic proceedings over the salaries only when the predefined conditions are met. Secondly, in blockchain, the payments will be analyzed only when the ID of the verified worker matches with the work records. The next point is that blockchain ensures the records are tamper-proof, meaning that no insider can manipulate the payroll records.
<h3 dir="ltr" style="text-align: justify;">Supply Chain Finances</h3>
The accounting organizations faced the problem of delayed payments from suppliers. The issue emerged because of the prolonged manual invoice verification. Moreover, manual reconciliation between vendors and clients delayed accounting processing. As blockchain provides real-time reconciliation, it can be integrated to eliminate the presented problems. This translates to real-time transaction recordings, removing the need to carry out manual reconciliation. One of the examples of blockchain in accounting is EY&rsquo;s blockchain analyzer reconciler applied to reconcile and match transactions. The approval of received items stimulates automated payment processing, which eliminates data manipulations, providing accounting with real-time financial tracking.&nbsp;
