Types of Crypto Wallets

Before you order a crypto wallet app in 2025, you should know about the variety. The type of wallet determines exactly how your company will earn. There are several popular options available today, including cold, hot, web, mobile, and other wallets. Let's take a closer look at all the existing types of cryptocurrency wallets in 2025 below!

Hot vs. Cold Wallets

The hot wallets are connected to the Internet, providing fast and convenient use for daily transactions. Mobile, web, and desktop apps are some of them. Whereas, cold wallets provide hardware wallets or paper wallets to store the assets offline, and are much more secure than hot wallets against hacks. It depends on your security needs and usage frequency, and you then have a choice between them.

Custodial vs. Non-Custodial Wallets

Your private keys are stored on the third-party custodial wallets, which the provider of such wallets holds ownership of your funds. They are easy to newbies, but need to trust. In contrast, the non-custodial wallets provide the users with complete control over the keys and crypto and provide privacy and security for that. For instance, you will lose access without a backup phrase and there’s no way to recover your assets.

Single-Chain vs. Multi-Chain Wallets

When talking about single-chain wallets, you should realize that they are compatible with only one blockchain. Bitcoin is just one example of blockchain that single-chain wallets can only support. They're simple but limit flexibility. Multi-chain wallets allow users to manage multiple cryptocurrencies across various blockchains within one interface. This broadens utility for those interacting with different ecosystems, DeFi platforms, or cross-chain apps.

Web, Mobile or Desktop Wallets

Web wallets are accessible from any device but are more exposed to phishing, online threats and other attacks. The use of mobile wallets is convenient for every day and most of these have QR features. Desktop wallets provide advanced features and better security for heavy users, but are less portable.

How to Create a Crypto Wallet App?

Actually, crypto wallet app development is a complex process. It is not enough for you to have coding knowledge to create a perfect wallet in a few months. You must have a professional team and plan the whole cycle properly. Below, we have put together a step-by-step process of cryptocurrency wallet development that you should know about.

Select Your Wallet Format and Core Functions

First, you have to choose the wallet type, either hot or cold, custodial or non-custodial, single chain or multi-chain. Login, currency support, transactions, and QR scanning … define core features. Make sure to align these choices with their audience and market needs. This phase is to provide such a clear vision on top of which further development will be streamlined.

Pick the Most Suitable Blockchain Framework

Choose a framework that complies with your application’s purpose. Solana or Polygon has speed, other lower fees. Ethereum is popular for its smart contracts and each is used for different things. Consider something like transaction cost, scalability, developer tools, etc.

UI/UX Design for an Easy-to-Use Interface

Create your crypto user interface, clean and simple. It must have a user experience that helps them operate as easily as possible. Make navigation clear, make the steps for the transactions minimal, and make the management of the wallet easy. Pick familiar design patterns, conduct yourself responsively, and use smart visual cues.

Develop the Backend and Integrate Smart Contracts

The next task is to build a secure backend to handle wallet operations, transactions, and blockchain communication. You should make wallet integration with smart contracts for decentralized functionality. Use APIs to connect with blockchain nodes and external services.

Implement Robust Security Measures

It's no secret that security is essential in crypto apps. What practices are there? Encrypt private keys, enable biometric authentication, and implement session timeouts. Ensure protection against phishing, injection attacks, and data leaks. Regular audits and compliance with security standards are essential to gain user trust and avoid breaches.

Conduct Testing and Publish on Mobile App Platforms

Test thoroughly across devices to identify bugs and performance issues. Conduct functional, security, and UX testing. Use both manual QA and automated tools. Once stable, publish your app on platforms like the App Store and Google Play.

Crypto Wallet Apps Features to Develop

Undoubtedly, you want a completely unique cryptocurrency app. However, there are a number of mandatory features that should be integrated into every platform. This is what makes a wallet functional and relevant to the expectations of the target audience.

User Login and Identity Verification

This is something that is very important for crypto wallets: they have to be decentralized, and secure user authentication to protect your assets. It follows compliance and minimizes fraud exposure with multi-factor login and KYC/AML checks. So it offers a wide range of biometric options, such as fingerprint or face recognition, to enhance the user experience and prevent unauthorized access.

Multi-Currency Cryptocurrency Support

Your future wallet should definitely support multiple cryptocurrencies. Why is it so? Users are not limited to buying and holding only one type of coin. Your project should support at least the most popular variants, including:

Bitcoin;
Ethereum;
Solana;
Tether.

A multi-currency wallet increases utility, simplifies portfolio management, and saves users from juggling multiple apps.

Secure Blockchain Transactions

With private keys stored securely within the app, all transactions must be encrypted and signed. There is added transaction history, fee previews, and confirmation prompts for transparency and user confidence. Real-time syncing with the blockchain ensures accuracy, while protection against double-spending or replay attacks is a must for maintaining trust and security.

Payment Gateway Connectivity

Integration of payment gateways provides users with ways to buy or sell crypto through cards or bank transfers. This links the fiat and crypto so one can easily use the wallet with or without a technical background. Maintain security and user trust and ensure gateways are licensed and reliable.

Smart Address Handling and Storage

This feature saves often-used wallet addresses automatically and checks transactions automatically. Features are tagged, grouped, and labeled, so it becomes simpler to manage contacts and avoid making mistakes. Verify and checksum validate addresses to detect typos or formats that do not match.

Paper Wallet Compatibility

The support for importing and exporting of paper wallets gives it a lot of flexibility. Paper wallets are a secure way of cold storage; the private keys are stored offline. Letting users scan or manually enter the keys from printed documents to get to the money.

QR Code Recognition and Scanning

Transaction speeds up with QR code among users, as they do not need to input the manual address. It lowers error, and is convenient particularly in retail, or peer to peer payments. Insert a reliable scanner equipped with a variety of wallet formats and dynamic codes.

Auto-Logout for Inactivity

Auto logout ensures that the user can't be given access to the app if he has left it open or unattended. Customize session timeout periods and have sessions automatically timeout if they are inactive. Combine it with re-authentication requirements to reopen the app.

What Factors Influence the Cost of Developing a Crypto Wallet App?

As you might have realized, the idea of creating a cryptocurrency wallet app is considered promising. However, one of the issues worth considering is pricing. Such a project can cost from 20 to 200 thousand dollars. How to determine the exact price? You should consider all the factors that affect the final cost.

The larger your project, the more expensive the development process will be. You should determine in advance what features you want to integrate, what type of application, and more. This will determine the approximate cost of the project.

The Key Factors That Affect the Cost of Wallet Development

App size. The more features and screens your wallet app includes, the higher the development time and cost;
Wallet type. Cold, non-custodial, and multi-chain wallets require more complex architecture, increasing overall expenses;
Number of supported currencies. Each additional cryptocurrency integration adds development hours and blockchain-specific setup;
UI/UX design. Custom, polished design with animations and seamless flows significantly raises the cost compared to basic templates;
Involved team. Larger teams with specialized developers, designers, and QA experts accelerate delivery but increase total budget.
