Introduction to Bitcoin and Bitcoin Wallet
Bitcoin is a decentralized digital cryptocurrency based on a cryptographic system. Bitcoin currency can be transferred from user to user on the peer-to-peer bitcoin network, and it does not require any intermediate for the same. On the other hand, a Bitcoin wallet is a software application used to store Bitcoins. Technically, Bitcoins are not stored anywhere, but there is a confidential pin that is given to the owner of the Bitcoin wallet. The wallet owner needs to use that pin to make transactions, and such kinds of pin codes are set for every Bitcoin address saved in the Bitcoin wallet. Moreover, the Bitcoin wallets come in four primary categories; desktop, mobile, web, and hardware.
Understanding Bitcoin Wallets
As we have mentioned above, there are four types of Bitcoin wallets, i.e., desktop, mobile, web, and hardware. Now let us discuss each category one by one.
Desktop Wallets: It gives complete control of the wallet to the user. Desktop wallets also allow users to create a Bitcoin address in order to send and receive Bitcoins. Moreover, Bitcoin Core, Hive OS X, Electrum, etc. are some of the known desktop wallets.
Mobile Wallets: Mobile wallets overwhelm the hindrance of desktop wallets. Mobile wallets can perform all the functions of a desktop wallet, and users can run the mobile wallets in their smartphones. These wallets add-ons more convenience, as users can directly make transactions by using their mobile wallets in their smartphones. Moreover, users can also pay at the physical store by using touch-to-pay” via NFC scanning a QR code.
Web Wallets: This type of Bitcoin wallet enables users to use Bitcoins on any online browsing platform. But, the selection of your web wallet should be sound enough, as it saves the user’s confidential pin online. Coinbase and Blockchain are some of the most popular Bitcoin web wallets.
Hardware Wallets: Hardware wallets are considered as one of the highly secure types of Bitcoin wallets. Users can connect these Bitcoin wallets to the computer by using a USB data port. Moreover, this type of Bitcoin wallet is safe from virus attacks.
Why Is Bitcoin Wallet App Security Important?
No doubt, it is very much essential to keep your Bitcoin wallet safe, as Bitcoin wallets are high-value targets for the hackers nowadays.

Nowadays, cracking simple passwords is not a big deal for hackers. Now the question arises – how do you protect your Bitcoin wallet? Well, the password process needs to be upgraded with two-factor or multifactor authentication. Undoubtedly, it will provide a thick security layer to the Bitcoin wallet.
2. Timed Logout
Timed logout is the next big thing when it comes to the safety features of a Bitcoin wallet. Financial apps need to be enriched with the timed logout feature, as it an essential safety feature for a prosperous cryptocurrency wallet app. Also, it improves the Bitcoin wallet app on the scale of security.
3. Deny Repeated Transactions
Generally, every month people make the same amount of transactions, and traditional financial apps allow the users to perform repeat transactions. In this scenario, hackers can make fraud, as they can easily hack their wallets to make the same transaction again. So, it will be good if the wallet software does not allow repeat transactions, as it reduces the fraud risk to a greater extent.
Brief Overview of Statistics
According to a report conducted by Statista, 23.95 million people all around the globe use Cryptocurrency wallets, which mean approximately 85.80%, and this number increased by 11.34% more in a limited period of time. No doubt, Cryptocurrency wallets are trending, and they contain keys to the monetary value of their users. So, they need to be extensively secure and functionally tested.
In the year 2015, Bitcoin comes to the spotlight at first, and it got a great response from online merchants and resellers, as they use Bitcoins to buy goods and services. Along with time, Bitcoin has become an accessible, reliable, and exotic online currency. Presently, you can use Bitcoins for a variety of purposes, such as buying electronic items, physical goods, hotel bookings, etc.
As you can see, the use of Bitcoins is rapidly taking space in the market, so the Bitcoin wallets need to be correctly tested to ensure wallet quality. Before we talk about testing steps in the Bitcoin wallet, you should know what’s going on in the testing world.
How to Test Bitcoin Wallet Apps?
Nowadays, most of the developers use blockchain API to develop mobile apps that can satisfy the needs of Bitcoin users. Moreover, if you want your Bitcoin wallet to meet the high standards of cryptography, you need to take the testing process seriously. Now let us discuss some of the testing steps that can help you meet the high standards of cryptography.
Bitcoin wallet holds real money so, you cannot perform its testing in production. In this scenario, you can go with the Testnet. The primary purpose of Testnet is to find all the loopholes of an app designed for the use of Bitcoin. Moreover, the transactions initiated on Testnet do not affect the financial value of bitcoins on the mainnet (primary network for Bitcoin transactions).
In some cases, Testnet does not fulfill the testing requirements. In that case, blocks are mined every 10 minutes, and you cannot boost up the process. So, if you want Bitcoins to be mined faster, you should go with the Regression Testing. It gives you complete control over the testing environment so that you can generate bitcoins as per your need by running regmode.
Security is the main regard when it comes to the testing of financial apps. The main aim of testing Bitcoin wallet apps is to examine the blockchain verification and make sure that the basic transaction structure is secure.
Bitcoin Wallet App Vulnerability Analysis
Basically, there are two main approaches when it comes to the vulnerability analysis of the Bitcoin Wallet App.
Static Method of Analysis
- Reverse Engineering
- Manual/Automatic Source Code Analysis
Dynamic Method of Analysis
- Network Traffic Monitoring
- Runtime Analysis
- File Activity Analysis
Importance of Manual Testing
Manual testing is also essential to reduce the risks concerning the device’s software and inaccurate structure of automation testing scripts. The following are some of the aspects that you should keep in your consideration while testing Bitcoin wallet apps manually.
- Jailbreak detection
- Device platform backdoor
Server Side Security
- Server configuration errors
- Loopholes in server code
- Insecure storage of sensitive data on mobile devices
