Blockchain technology has made a breakthrough in the field of secure transactions.

So you can create your own Bitcoin wallet to take the most of growing cryptocurrency’s popularity. This article lets you learn what features to add, what libraries can be used for development, and much more.

What Is Bitcoin Wallet and How to Use It?

The crypto wallet is used to store cryptocurrency and make secure transactions. It uses blockchain records, as well as public and private keys. Most cryptocurrencies have their own wallets, for example, Bitcoin. Others recommend using third parties. To create an app with cryptocurrency payments, you should add integration with the wallet.

Using cryptocurrency wallets offers a large number of advantages. One of the most important ones is anonymity and security. Thus, every transaction creates a new block in the blockchain with complete information about its details. Furthermore, this data is securely protected, so you can only see the transferred amount and address of the wallet. 

All the information recorded in the blockchain cannot be changed later. Also, a digital signature is required before sending a transaction so your cryptocurrency is well-protected from third parties. Thus, using a Bitcoin wallet for payments significantly increases their security. 

There are a few of the most common ways to use crypto wallets, namely: 

  • Payment in stores. There are already many online stores where cryptocurrencies are the official payment method. However, thanks to the startup CryptoPay, you can create a debit card linked to your Bitcoin wallet. With it, you can pay with cryptocurrency in almost any store.
  • Wage payment. BitWage has created a platform that allows you to pay wages in Bitcoin. This method is incredibly convenient for freelancers working in other countries. 
  • International transfers. Using Bitcoin wallets for transfers to other countries can save costs because you do not have to pay massive commissions.
  • Protection against fraud. As we have already mentioned, cryptocurrencies are a very secure payment method. They are even ahead of banking institutions in terms of safety.

The fields of cryptocurrency applications are constantly expanding due to the increased interest in this topic. Thanks to the newest top blockchain startups, cryptocurrencies are now used in FinTech, logistics, retail, and other industries. Moreover, you can also implement a Bitcoin wallet as a payment instrument in ready-made software or include this function when developing a new solution.

Mobile Bitcoin App MVP Features

Most Bitcoin wallets have similar features. Consider them if you want to create your own application. For example, the MVP features of a mobile cryptocurrency wallet include the following: 

  • Authorization. The registration and login must be as secure as possible.
  • Personal account. Here the user can check his balance, make transactions and track the history.
  • Exchange rate. It will help to track the value of Bitcoin relative to traditional currencies.
  • QR scanner. The feature allows quick transfers by code.
  • Trading. Users will need this feature for buying and selling Bitcoin.
  • Push notifications. The user will be notified of new transactions or changes in the exchange rate.
  • Security. Use a password code or biometric data to protect every account.

You should use the appropriate tech stack to make all these features work correctly. Let’s take the example of the application from Blockchain Luxembourg Ltd.

So to create an app, they used the following tech stack: 

  • Java, Clojure, and Node for the backend
  • AngularJS for frontend
  • MySQL – database
  • AngularJS, NodeJS for web apps

You do not need to learn all the technical details yourself. Instead, you can turn to an experienced software vendor who will create an application for you by selecting the most suitable and modern technology.
