Cryptocurrency Wallet Development: All You Need To Know

Updated: 16 May, 2024

By 2030, the global market for cryptocurrency payment apps is expected to exceed $2.108 million, growing at an annual rate of 18.52% over the next eight years, according to Research and Markets.

This represents a 290% increase from 2022, driven largely by the growing use of cryptocurrencies, improved security of crypto apps, and the cost savings they offer. Seeing the future potential and business opportunities in cryptocurrency, many companies have already started investing in digital crypto projects.

In this guide, our team explains the basics of creating a crypto wallet app for your business. You’ll learn about the main types of crypto wallet apps, the key features they need, and a step-by-step plan to help you build a scalable and functional crypto application.

Crypto App Wallet: Definition & Benefits

A cryptocurrency wallet app is a software designed to manage crypto assets’ ownership, transfer, and storage. Unlike standard digital wallets, it doesn’t hold a user’s coins. Instead, it holds the keys to access these coins, which are stored on public blockchain networks.

Essentially, crypto wallet apps act as digital managers that store users’ public and private keys and track their cryptocurrency balance in one place. When stablecoins, non-fungible tokens (NFTs), or other crypto assets are transferred to the wallet, their ownership is linked to the wallet’s address.

Cryptographic keys are crucial for verifying user addresses and conducting transactions, making security a top priority. This is where developing a custom crypto wallet app becomes important.

Cryptocurrency wallet development ensures the security of your digital currencies, offers better control over cryptocurrencies, and provides a smooth, user-friendly experience.

Once you decide to build a cryptocurrency wallet app, it’s crucial to plan every detail of the development process. Let’s explore the types of crypto wallets and the essential features to include in your custom application.

What Are the Types of Crypto Wallets?

The functionality and technologies needed for developing a crypto wallet app depend largely on the type of wallet you choose. Therefore, the first step in creating a crypto wallet is to determine which type best suits your app’s features, project requirements and needs:

Cold Wallets (Hardware Wallets

These are physical devices designed to store cryptocurrency offline. Cold wallets offer extra security by keeping private keys completely isolated from the internet, making them more resistant to online hacks or breaches.

Hot Wallets 

These are software-based wallets that stay connected to the internet. Hot wallets provide easy access to cryptocurrencies, making them ideal for active trading or frequent transactions. However, they are less secure than cold wallets due to the continuous internet connection.

Hybrid Wallets

These combine elements of both cold and hot wallets. They typically store the majority of funds offline (like a cold wallet) for added security, while keeping smaller amounts online for easy access and transactions (like a hot wallet).

Choosing the right type of wallet is just one part of creating a secure cryptocurrency wallet app. Identifying the essential features and technologies for your application will help you develop a cost-efficient and competitive solution for crypto payments. Let’s review the key features that can enhance the performance of your cryptocurrency platform.

Essential Features in Crypto Wallet Apps

Planning the app’s functionality is crucial for shaping your future crypto wallet’s structure. It also helps you understand its use cases and identify its advantages over existing market alternatives.

Here are the most fundamental features to include in crypto applications, whether you’re creating a custom digital wallet app or even building your own crypto casino:

User Authentication

Ensuring that only authorized individuals can access the wallet is essential. This feature is crucial for meeting various crypto compliance standards such as AML and KYC. Implementing secure user authentication is technically complex and requires expertise in the latest authentication protocols and security standards. Common methods include secured login credentials, biometric authentication, and multi-factor authentication (MFA) to prevent unauthorized access.

Support for Multiple Cryptocurrencies

Multi-currency apps have a competitive edge over single-currency wallets like those for Bitcoin or Ethereum. Integrating various currencies enhances the usability of your digital wallet app, making it more versatile and functional. Additionally, multi-currency wallets allow users to diversify their portfolios, benefiting both businesses and customers.

Secure Blockchain-Based Transactions

Prioritize the security of on-chain transactions and other cost-related operations when developing a crypto application. Security measures include encrypting sensitive data, verifying user accounts and signatures, and integrating blockchain security protocols. With the help of blockchain professionals, you can identify the essential security components for your project. These experts will help you build a secure, functional, and efficient crypto wallet for your business and customers.

Integration with Payment Gateways

This feature allows users to make payments directly from their crypto wallets using integrated external payment processors or gateways for cryptocurrencies. These crypto-based technologies function similarly to standard payment processor gateways and bank credit card systems, simplifying transactions without compromising security.

Efficient Address Management

Effective address management helps users track and identify wallet addresses easily. Beyond the technical aspects, developers must ensure the system offers a convenient design and user-friendly experience for managing crypto addresses.
