How the Story Begins

However, nowadays, having only a website isn't enough to effectively operate a digital business. Therefore, at the Client's request, we proceeded with the cryptocurrency app development project.

It all started when the Client entrusted us to design and develop a landing page. After that, since the results of our work completely satisfied him, he also ordered us to create a fully functional website.

Team Working on the Project

Several Agilie departments had been working closely on the Wallex project. We involved web and mobile developers, QA engineers, and, of course, UI/UX experts in the app creation.

The working process itself was supervised by Sergey Melashich, our senior developer.

UI/UX Challenges & Ideas

We developed the app’s UI/UX from scratch. And the main challenge was to provide the best user experience.

That's why we've resorted to the logic that is most typical for the e-wallet's design. This made the application interface intuitive and user-friendly.

As for the choice of a color scheme, we were guided by both the Client's wishes and the users' expectations.

Development Challenges to Overcome

However, nowadays, having only a website isn't enough to effectively operate a digital business. Therefore, at the Client's request, we proceeded with the cryptocurrency app development project.

Cross-platform development

Our cryptocurrency app development project is based on a cross-platform approach, which is a more cost-efficient solution since the application works on any OS platform. But the coin has a downside.

Above all, the developer must not only understand the technology stack used but also have some knowledge of the operation of iOS and Android platforms. In addition, he should be able, if necessary, to create certain modules in their respective languages.

We did it with a bang and developed a high-performance application that works quickly and efficiently.

Working with multiple cryptocurrencies

The second challenge of the project was that it included multiple cryptocurrencies. Therefore, we had to unify the process of interaction with them.

We also needed to provide a basis for future application scaling so that one could add new currencies with minimal effort.

Interaction with blockchain

We didn't bring up our own nodes and interacted with blockchains through electrum servers. Since these servers only support the TCP protocol, we needed to create an additional proxy service to convert HTTP to TCP.

Primarily, this microservice is responsible for decoding transactions. In addition, it monitors the status of electrum servers to provide smooth interaction with the blockchain.

The complexity of market data processing

Another challenge of our project was the aggregation and processing of cryptocurrency market data and its further transfer to the user. We had to find a way to render all the charts without reducing the application performance.

And our team did an excellent job with this task.

Securing the Wallex app

Any financial application must be well-protected to ensure the security of money transactions. And the Wallex app is no exception.

To maximize the app protection, we've used the most modern encryption methods. Also, we ensured that information about private keys remained inaccessible to the server, which additionally secured the crypto-wallet.

Release of the new 14 iOS

Also, work on the project was complicated by the fact that it coincided with the release of iOS 14 and the update of the NativeScript framework to the 7th version. Consequently, our experts had to consider new and so far little-known system requirements during the cryptocurrency app development process.

Technology Stack Used

Nrwl

TypeScript

NativeScript

Angular

NestJS

PostgreSQL

Redis

Home Screen

The app's home screen displays the most meaningful data, which is the state of the user’s financial account. And the first thing that catches his eye is the total balance in US dollars.

;

Also, the user sees all his crypto-wallets with an indication of the monetary balance on each one. So he gets an idea of his financial status at a glance.

;

Transaction Details

Our application guarantees the best user experience, and therefore any cryptocurrency transaction is simple, clear, and transparent.

;

Among other things, the user is able to access the details of his transactions and see the status of each one. Also, this feature allows him to understand which of them have been successful and which have failed.

;

Exchange

Do you need to exchange cryptocurrency? It's easy! Our application will help you with this.

;

The Wallex app supports all popular cryptocurrencies. And you can freely exchange your funds and move them from one e-wallet to another depending on the type of cryptocurrency.

;

Sending cryptocurrency

The main task of cryptocurrency app development is to create a digital wallet with the ability to send your funds to other users. Undoubtedly, the feature belongs to the key ones.

;

Our Wallex app allows you to do this quickly and safely. The whole process takes a minimum of time.

;

Settings

And the last feature making our digital wallet so convenient is the Settings.

;

You can change the password, passcode, and other parameters as needed. And of course, there is an opportunity to use the Contact Us form at any time you want.
