This article will provide guidance on creating Web3 mobile apps. The project’s targets will be defined, technical documentation will be created, the functions will be determined, the UX/UI interface will be designed, and the technology stack will be chosen, all with examples and additional information. It will also touch on what a Web3 mobile application is and how it differs from conventional ones.

What are Web3 mobile apps?

We all know that Web3 or Web 3.0 refers to a variety of technologies that, over the next ten years, will fundamentally alter the internet. For further details about Web3, you can take a look at this article.

Web3 mobile apps are mobile software applications that make use of one of Web3 technologies, such as blockchain for decentralization, artificial intelligence, neural learning, big data, VR/AR, dimensional interfaces, and distributed computing.

How do Web3 mobile apps differ from Web 2.0 applications?

The architecture of Web3 applications significantly differs from that of Web2 applications. For instance, the website Medium enables users to interact with one another’s content by liking, sharing, and commenting on it. Although Medium appears to be a simple resource as a Web2 application, the architecture uses a variety of technologies:

  • It first needs a place to store posts, user data, comments, likes, tags, and other content. A constantly updated database, such as one on a local server or in the cloud, is required for this purpose.
  • Second, the internal business logic of the website must be defined in Python, C#, Node.js, PHP, or Java. For instance, it should be aware of what takes place when a brand-new user creates an account, posts something, likes it, or leaves a comment.
  • Thirdly, the user interface’s logic must be understood by any external code that is written in JavaScript, CSS, JQuery, HTML, TypeScript, or React. It must specify things like how the user experiences the website and what happens when they interact with each page element, for instance.

With all of this knowledge, you can visualize how a Web2 application works. When you write or publish posts and comments on our site, you can see how Medium works.

Since the data is in a database and the code is kept on an internal server, it is a centralized type of architecture. The creator (owner) of the application controls and partially owns both the code and the data, which raises concerns about the security and privacy of the data.

A centralized server or database that houses user and application data is absent from Web3 applications, in contrast to Web2 applications like Medium, Facebook, Microsoft Word, WhatsApp, Netflix, or PayPal. The P2P anonymous nodes are supported by the technology that uses a blockchain to crowdsource the public server (anonymous internet users).

Additionally, blockchain technology permits the use of smart contracts to automate internal business logic.


This illustration shows how the Web3 application’s backend has changed. What happens to the frontend, do you wonder? Although there are currently few noticeable differences, this will change in the future. Graphical user interfaces (GUI), as we know them today, will be replaced by interfaces for virtual and augmented reality.

How to create Web3 mobile apps?

Custom development is necessary to create a Web3 solution because it’s the only way to give your product respectable security and dependability. To develop a Web3 mobile app, startups should follow the 8 steps below.


Step 1: Initial phase

The first step in any blockchain startup development, including Web3 mobile applications, is to define your project’s concept. At this point, you and the development team meet in person or online to discuss every aspect of the upcoming Web3 solution, including your desired business outcomes and the specifications for the design and functionality.

You must possess the following at this stage:

  • The details of the tasks and goals. Your Web3 application’s business tasks and metrics must be precisely and in-depth described. If the developers have a clear and concise description of what they need to create, their job will be much easier.
  • The project’s description. Significantly, your project’s functions are thoroughly explained as well. It requires figuring out how and why users will use the application. You must also comprehend how your WEB3 application will be monetized.
  • Drafts of applications. These are typically handwritten user interface designs that visually highlight crucial elements to take into account when developing the design.

You should ideally get the descriptions and drafts ready before getting in touch with the developers. Since creating an application is new to you, it won’t be a big deal if you choose not to do it. An excellent developer will assist you in defining it by posing the proper queries and offering relevant examples.

Step 2: Develop the technical documentation

The creation of a software document or technical specification is required for the second stage of a mobile application using Web3 solutions. It serves as a development guide for the upcoming product, outlining the business logic and defining the technologies used, as well as setting deadlines, budgets, and even risks.

Usually, the technical documentation is provided by the product developer in accordance with the client’s report on the project. The technical documentation, however, might be completed by the client. The developer needs the following to create the technical document:

  • To specify the number of users and their roles for the upcoming WEB3 application (buyer, seller, administrator).
  • To provide tools for project execution.
  • To provide the user stream structure.
  • To provide structure for the user interface.
  • To specify the primary application features.
  • To ascertain the architecture of the application.

The development team requests the client’s approval of the technical documentation when it is finished, after which they estimate the project’s budget. The developer will perform a functional decomposition once all the details have been decided upon, divide user streams into tabs and functions, establish their priorities, and create a project development plan. The tasks will be divided into two categories: prime (those that must be implemented in the MVP) and secondary (those that can be added after the MVP has been created or even after the mobile application has been released and deployed).

Step 3: Create the Web3 mobile application prototype

One of the most important phases of development is creating the prototype for the Web3 mobile solution because the success of the project as a whole depends on the interface design. Users will delete the application and never use your product if they dislike the user interface or find it difficult to understand. Additionally, they might provide unfavorable feedback.

To prevent it, your development team must research the competition and the target market to comprehend the preferences and needs of the users and implement them in accordance with the project’s technical documentation and design trends. The procedure typically includes three steps.

  • Creating a paper-based interface design sketch. It will display the key elements of the upcoming project, such as the interaction, logic, and number of tabs;
  • Creating high-fidelity wireframes that depict the design as the users see it. The wireframes aid in visualizing the application design in order for the client and the developers to see how the application will ultimately look.
  • Creating a clickable prototype, or an animated version of the interface design with all the icons, buttons, and transitions. This prototype aids in streamlining user flows and identifying logical holes and technical inconsistencies in the original concept.

Step 4: Approve the final UX/UI design

The UX/UI designers will use the application prototype created in the previous step to help them design each tab. They need to agree on it with the client, and test it in a focus group made up of members of the target audience. The client will consequently get:

  • A model for the application’s navigation.
  • Design of buttons and icons.
  • The contents of the text field.
  • Other visible components.

The time required to develop your design will range from one week to three months, depending on its complexity. If it is a Web3 video game or a virtual environment for the metaverse, the design will take a year or even longer.

Following completion of the design development, you will have:

  • A Web3 solution’s UX wireframe
  • A design for an iOS and Android app
  • A prototype of an interactive application

Step 5: Initiate the development of the application

At this stage, there are several possible outcomes. You could begin by coming to terms with the concept, namely creating the minimum viable product (MVP), which will demonstrate that your concept works and that there is a market for it. This is a good option for clients who want to quickly and inexpensively assess the perspective of their ideas.

Next, you can begin creating the full WEB3 application, which includes all features, integrations, and design options. This is a way to launch products in a market that is cutthroat and where there are competing products. It calls for a high-quality product with attention to detail on par with or better than its rivals. The only way to draw users is by doing this.

Regardless of your decision, the WEB3 application’s developers must create the following:


The user will interact with this area of your WEB3 solution. As an illustration, the following technologies and development tools (technology stack) are used by cryptocurrency wallet developers:


  • Programming languages for the web: Angular.JS, React.JS, and Vue.JS.
  • Programming languages for App: Java, Kotlin for Android, and Swift for iOS.
  • Architecture: MVC, MVP, MVVM, and VIPER for iOS and MVVM for Android.
  • IDE: Android Studio and Xcode for iOS.
  • SDK: iOS SDK and Android SDK.


This component is in charge of the application’s internal logic. It links the interface to the level of data access. Building a cryptocurrency wallet’s backend requires:

  • Smart contracts: Ethereum Virtual Machine or BSC
  • SQL database: MySQL, PostgreSQL, MariaDB, MS SQL, and Oracle.
  • DevOps: TeamCity, GoCD Jenkins, WS CodeBuild, and Terraform.
  • NoSQL database: MongoDB, Cassandra, and DynamoDB.
  • Search engines: Elasticsearch and Apache Solr.
  • Programming language: Java, PHP, and Python.
  • Framework: Flask, Spring, and Symphony.
  • Cache: Memcached and Redis.

Step 6: Test the product

A smooth product launch depends on quality assurance at every stage of development, especially when developing software that deals with money and business user data. To check for various vulnerabilities, testers and QA specialists use manual and automated testing. These tests typically consist of the following:

  • Test for compatibility: Utilizing the developed mobile app on a range of devices and well-known operating systems;
  • Device compatibility testing: Examining how the developed mobile application functions and appears on screens of various sizes;
  • Low-level resource testing: Testing the functionality of the application when the battery is low, the Internet connection is sluggish, etc.;
  • Security testing: Look for weaknesses that could be exploited to compromise the application or cause issues with how it functions.
  • Interface test: Examining the functionality of the menus, buttons, and navigation.
  • Beta test: Focusing groups were first used to study the application and get feedback.

Step 7: Deploy the Web3 mobile application

When a Web3 mobile app is ready, it’s time to publish it on Google Play and the Apple App Store and deploy it to the cloud. However, you must first confirm that your mobile app satisfies the criteria of these app stores and gather information about it.

Support after launch is not required. However, if you want to develop and improve your project, it is strongly advised. Both an internal team and your application developer can be consulted to arrange the support work. The latter option isn’t always an option though because developers might be moved to work on other projects. As a result, you must decide on support in advance. After that, the developers will either start working on your project for a long time or prepare a specific team.

Step 8: Product Support (Optional)

Support after the product launch is optional. But if you want to advance and develop your project, it is highly advised. You have two options for organizing the support work: working with your application developer or using an internal team. The latter choice, however, is not always feasible because developers may be moved to work on other projects. As a result, you must decide on support in advance. After that, the developers will either start working on your project for a long time or prepare a specific team.

How much does it cost to create a Web3 mobile application?

The complexity and scope of blockchain solutions and other IT projects determine their cost. In light of this, it is impossible to predict in advance what the development budget for a given Web3 mobile application should be. For the US, Western Europe, and Eastern Europe, we will only provide an approximation of the price of developing a cryptocurrency wallet in the picture below.
