Development of a mobile crypto wallet app for iOS

Investing in cryptocurrency is one of the ways to protect your funds from the crisis and inflation. Bitcoin, Ethereum and other blockchain-based assets are not controlled by banks and large corporations, so they can help save money during unstable periods.

To invest without risks, you need to use a reliable intermediary, and since there are no crypto banks yet, only specialized services are available to users – cryptocurrency wallets.

They do not store coins directly, but only ensure the efficient management of their funds in the blockchain network.

In this article, we will talk about how to develop your own crypto wallet for iOS, what technologies are used for this, and what functionality will need to be implemented.

Cryptocurrency wallet for iOS is installed directly on a smartphone and can have a variety of functionality. However, there are some basic tools that ensure its security and user experience, here are some of them:

• Receiving and sending transfers is a functionality that ensures the fulfillment of the main tasks of the wallet.
• Buying and selling – the user should be able to purchase cryptocurrency for fiat or another currency.
• User profile – a personal account that displays the current package of assets, transaction history, source phrases, security settings and other important information.

• Authorization – The authorization functionality is the backbone of wallet security. It performs verification of the entered password, private keys and secret phrases, which open access to the use of assets.
• a QR scanner is an important part of a mobile crypto wallet that allows users to make contactless payments quickly and conveniently.
• Security and protection against DDoS attacks – a feature that protects the user’s assets from unauthorized use.

AVADA MEDIA specialists can implement this and any other functionality for cryptocurrency wallets on iOS. The possibilities of the created software are limited only by the requirements of the customer.

For the production of cryptocurrency wallets for the iOS operating system, two main technologies are used:

• Swift is an open source multi-paradigm programming language from Apple, native to iOS development. They use modern syntactic constructions, provide a high level of code security and reliability.
• Flutter is a cross-platform development kit from Google that uses the same codebase for both iOS and Android apps. That is, a wallet created using this technology will work on two mobile operating systems at once.

It is also worth adding that the creation of a crypto wallet is a complex process that involves a whole team of specialists: marketers, designers, planners, programmers, and QA engineers. Manages technical development PM-manager. He provides feedback to the customer and is responsible for ensuring that the project is implemented in strict accordance with the terms of reference and on time.

The production process can be divided into several main stages. Let’s consider the main ones in more detail.

Stage 1. Analysis and planning

The development of any software, including a cryptocurrency wallet, begins with setting specific tasks and analysis. At this stage, all the information that will be necessary for further production is collected and recorded.

Stage 2. Technical documentation

The technical documentation describes in detail all the characteristics and parameters of the cryptocurrency wallet being developed, the features and implementation plan of the functionality, the blockchains that the project will work with and the technologies that will be used in the production process.

On the basis of the finished document, the timing and cost of software implementation are calculated.

Stage 3. Designing the interface structure

A logical and predictable interface helps a person to easily find the necessary functions already at the first launch of a mobile crypto wallet. This positively affects the user experience and increases the chances that a person will continue to use the product for a long time.

Stage 4. UI design development

The user interface (UI) design forms the first impression of a crypto wallet, so it should convey the values ​​of the product and build the trust of the people who plan to use it to manage their finances.

UI design covers the development of the appearance and interactivity of the project. The colors and fonts that a person sees, the buttons they click on, and the animations they interact with are all parts of the user interface that are created in this step.

Stage 5. Programming

The technical development of a crypto wallet consists of two parts:

• Frontend – The crypto wallet design layout transforms into smart phone-readable code and turns into an interactive user interface that a person can interact with.
• Backend is the development of the server part, which includes the creation of all the functionality and logic of the project. The backend is responsible for working with databases, blockchains, transactions, and so on.

The client and server parts of the crypto wallet closely interact with each other: the frontend receives requests from the user and sends them to the server, where they are processed and sent back to the client with the appropriate result, in a format that is easy to understand.

Stage 6. Testing

QA-engineers, they are also quality assurance specialists, are involved in all stages of the production of a crypto wallet and optimize the production process. In addition, they develop and conduct tests that identify all possible bugs and problems with the functionality of the product for their timely elimination.

Stage 7. Development and support

After deploying a mobile crypto wallet and starting to use it in real conditions, users may find hidden errors.

To fix them, developers are again involved in the project, who identify and eliminate the cause of the bug.

Also, over time, it may turn out that the current capabilities of the crypto wallet are not enough, so the technical specialists continue to work on the project in terms of developing and improving the functionality.
