When the blockchain configured properly, it can provide a decentralized solution that reduces the number of intermediaries, increases transparency, and ensures data security and eliminates unauthorized access at the same time. Thanks to this, this technology can be used as a replacement for the traditional base when creating an application architecture for Android and iOS. In this article, we will look at how to create such an application. We also advise you to carefully read our article about TOP 5 BLOCKCHAIN ​​TRENDS OF 2022.

Step 1. Defining the idea

As with any product, an idea is the first thing you need to think about before you start developing your application. At the same time, you must be sure that you really need a blockchain to implement it. So, if you want to create a mobile video game, torrent client, online magazine or aggregator of something, then the blockchain is not needed here, since it does not bring any advantages compared to the traditional approach.

Blockchain technology will be useful in the following cases:

Step 2. Finding a technical partner


Once you have decided what kind of blockchain applications on Android & iOS you plan to create, your next step is to find a developer. You need a technical partner, because creating a mobile application on the blockchain using templates, as is the case with WordPress sites, will not work. Blockchain requires certain knowledge and skills, and also costs 15-30% more.

What to pay attention to when looking for a technical partner is described in the article: «How to choose a software company».

Step 3. Choosing the optimal platform

At the next stage of creating a mobile blockchain application, you need to decide on which blockchain network you want to create your product. The choice must be made based on what properties you need.

Here are some of the most popular options among developers:

Step 4. Development of the application framework

The process of building a blockchain application on Android & iOS is similar to the process of building a house. Before you start laying the foundation, you need to develop an architectural plan that will give you an idea of what kind of house and what you will be building of. The framework of your application is the same architectural plan that you will use to build your software product.

Frameworks depict the basic structure of an application, its appearance, user path, approximate appearance of application screens, and so on. With such a scheme, developers can understand what functionality they need to implement and how long it will take them to do so, which helps to budget the project.

Frameworks development usually requires two steps:

Step 5. Creating the user interface

Once the framework has been created, you can start developing an attractive user interface for your blockchain application. This is a very important stage, since the user experience will depend on it - how the user perceives the interface: pleasant colors, convenient icons, intuitive transitions between screens. Or vice versa: it is not clear what and how to do, small icons that cannot be hit, some kind of toxic color scheme.

Here's what designers should do at this stage:

Step 6. Implementing the application in code


After designing the UI / UX, the process of implementing this design and application business logic in code begins. This usually means implementation at the background (backend) and foreground (application interface) levels. This process may look different depending on several aspects:

This usually involves creating a minimum viable product (MVP), which is used to validate the concept and receive feedback. With this data, the product is being finalized to the release version.

Step 7. Testing and verification


Thorough testing of your blockchain application is one of the prerequisites for developing blockchain applications if you intend to add your product to the listings of the Google Play Store or Apple App Store. These sites necessarily require that the app be tested based on various parameters and criteria, be free of errors (critical) and work well in any use case. In addition, you also need to check the performance of the application under increased load.

This is done by QA engineers, or specialists.

Step 8. Launch and Deployment


Deployment is the last step in the development process. Once the product is ready and passes all tests, it can be registered on such marketplaces as the Google Play Store and Apple App Store. For this you need:

  1. Register on the Google Play Console and Apple Developer.

  2. Fill in the appropriate form for adding an application to the listing.

  3. Pay for registration ($ 25 for Google, $ 99 for Apple) and agree to the user agreement.


After the application gets into the marketplaces, you need to make sure that your product does not lag behind the development of competitors. This will require the maintenance and support of the application, which may include updates to libraries, framework and operating systems, as well as adding new features and making changes to the application based on current business needs.

Step 9. Promotion of the project


For your blockchain application to become popular, you need a marketing strategy that targets your target audience. Here's how much it can cost depending on the promotion channel:
