BlueWallet is a non-custodial wallet that specializes exclusively in Bitcoin and supports Lightning Network technology. Its functionality includes a wide range of features for ease of use and implements many modern functions of bitcoin wallets. In addition, special attention is paid to simplifying the interface in order to make it accessible to beginners.

Experts in the field of cryptocurrencies have studied BlueWallet and evaluated its capabilities from basic to advanced. The aspects of usability, security and privacy were considered. Like many wallets designed for exchange, BlueWallet is available in almost all countries where it can be found in app stores. It is aimed at a global audience and supports more than 20 languages, including Chinese, Japanese, Portuguese, Spanish, Indonesian, Russian, Ukrainian, Italian, German, Swedish, Norwegian, French, Danish and Turkish. In addition, users have the ability to display the value of their bitcoin assets in more than 20 currencies.

Setting up a wallet

Blue Wallet provides the user with freedom of choice and does not impose a specific procedure for setting up. When the application is first launched, the user is presented with a simple screen where he can start the process of creating a wallet by clicking the "Add Now" button. There is no unnecessary information on this screen, which may not seem informative enough for beginners.

After clicking the "Add now" button, the user is given the opportunity to enter the wallet name and select the type: Bitcoin or Lightning. This can cause confusion for unaccustomed users, since there is no obvious connection between Lightning and Bitcoin in the interface.

When creating a new wallet, BlueWallet prompts the user to write down the 24 initial recovery words. This method is standard for most bitcoin wallets and is an important part of ensuring the security of user funds. However, some aspects of this process can be improved for a more user-friendly experience.

On the initial word recording screen, BlueWallet starts the word counter at 0, which may seem unusual to ordinary users. However, there is no mention of the risks associated with misspelling or loss of these words, and there is also no process for verifying the spelling of words by the user. This can lead to potential security issues.

The application also does not allow you to take screenshots of the initial words to prevent them from spreading undesirably. This is important to protect the privacy and security of users. In addition, although when opening the "Get" tab in the wallet, a warning appears about the need to create a backup copy of the source words, it is recommended to include more explicit reminders about this at all stages of creating a wallet.

Some advanced options, such as choosing the address type, are available only when activating the advanced mode in the application settings, which may be inconvenient for some users and disrupt the unified wallet creation process.

Overall, BlueWallet provides a simple and intuitive wallet creation process, but some aspects, such as explicit security reminders and convenient word validation features, can be improved to provide a better user experience, especially for beginners.

Lightning Wallet

The Lightning Network (LN) is a scalable second-tier solution designed to speed up transactions and reduce fees on the Bitcoin network.

Although Lightning technology is still in the experimental stage and requires certain technical skills to set up, BlueWallet makes the process of using LN more accessible. Users can easily set up a wallet and start sending or receiving lightning-fast payments. It is important to note that the Lightning wallet in BlueWallet is custodial, which means that users do not have full control over their funds. However, it's a great way for beginners to get to know Lightning Network technology.

In addition, BlueWallet provides access to the "Lapps Marketplace", a carefully selected list of applications and services that use lightning-fast payments. This allows users to explore the various possibilities of using LN and find useful applications that meet their needs.

Thus, BlueWallet provides an easy and convenient way for users to start using lightning-fast payments and explore the opportunities provided by Lightning Network technology.

Watch-only Wallet

BlueWallet offers a "watch-only mode" feature that allows users to check the balance and transactions of their wallet without importing the private key, thereby avoiding the possibility of initiating transactions. This provides an additional layer of security, since the private key is not imported, and the wallet can only be used to view data.

To create a BlueWallet-only wallet, the user needs to import the xpub key from an existing wallet. This process requires exporting the xpub account and then importing it into a new account. It is important to note that in order to use the wallet for viewing only, you must delete the original BlueWallet account, since the application does not support access to wallets for viewing only through a separate login.

Although this process is not the easiest, it provides the user with the ability to use the wallet only for browsing in BlueWallet with an additional layer of security.

Special transaction fees

The BlueWallet wallet provides users with the ability to set up a transaction fee manually, which allows you to control the speed of transaction confirmation and avoid overpayment. This is especially useful in situations where flexibility in choosing a commission is required.

Users can set their own transaction fee, expressed in Satoshi per byte, starting from 1 Satoshi per byte. In addition, the "Allow commission increase" function is available in the advanced settings of the transaction screen. This allows you to change the transaction fee after its broadcast and before its confirmation. This is useful if the user has chosen too low a commission or changes his mind about the desired transaction speed. For example, if a commission of 5 satoshi per byte is selected, but the transaction is still not confirmed after an hour, you can increase the commission to 10 Satoshi per byte to increase the priority of the transaction.

In addition, BlueWallet supports the "Child-Pays-For-Parent" (CPFP) function, which allows you to increase the sender's commission by paying the difference. This can be useful if the sender has set a very low commission and the user wants to speed up the confirmation of the transaction.

Thus, these features allow users to flexibly manage transaction fees in BlueWallet, ensuring control and efficient use of funds.

Package fees

Batch processing of bitcoin transactions, where a single transaction can contain multiple destination addresses, is an effective way to save on fees and improve user privacy. BlueWallet has successfully implemented this feature, making it available to end users.

When creating a transaction in BlueWallet, the user can easily add multiple recipients and specify the amount he wants to send to each of them. This allows for efficient cost management and reduces the number of transactions required, which ultimately leads to savings on fees.

In addition, using this feature can help to increase user privacy. For example, one of the recipients may be assigned a wallet managed by the user himself, which creates the illusion of multiple transactions and complicates tracking the flow of funds. This is a technique known as coin connection, which helps to improve the privacy and anonymity of users on the bitcoin network.

Thus, BlueWallet's batch transaction processing feature not only saves on fees, but also improves user privacy, making the wallet more attractive to experienced bitcoin users.

Safety

BlueWallet offers a variety of security features that ensure the protection of user funds and their privacy:

1. Mnemonic Recovery Phrase: You don't need to worry about saving a separate private key for each public address. BlueWallet uses a 24-word mnemonic recovery phrase that allows you to recover your funds in the event of a lost phone or a forgotten PIN.

2. Biometric Authentication and Encryption: Users can use biometric data to unlock, delete and export a wallet or to sign a transaction. In addition, BlueWallet supports wallet encryption with an additional password, providing an additional layer of security.

3. An additional password to unlock a fake wallet: You can set an additional password to unlock a fake wallet, which provides an additional level of protection in case of an attack or unauthorized access.

4. Privacy: BlueWallet provides several features to ensure user privacy, such as trap wallets, the use of HD wallet addresses to prevent address reuse, and the ability to sign and broadcast transactions offline to mask an IP address.

5. SSL and VPN: Users can connect to their full Bitcoin nodes through a secure and private connection using SSL and VPN. 

6. Multi-wallet Architecture: BlueWallet supports a multi-wallet architecture to separate UTXOs and keep user assets private. 

7. Development of advanced Privacy features: The development team is working on more advanced privacy features such as Payjoin and coin control to further protect users.

Overall, BlueWallet offers a wide range of security and privacy features, making it a reliable choice for storing and managing bitcoins.

Technical support

Although support is not directly related to wallet functions, it plays an important role in the overall user experience. A support team that responds quickly and efficiently to user requests can significantly improve the experience of using a wallet.

Despite the lack of real-time chat, the support team is always in touch and provides all the necessary information in an understandable form. There is also a support section on the site where you can find answers to all popular questions and find an email address to contact the BlueWallet team.

This shows that BlueWallet pays attention to the quality of customer service and strives to provide a positive experience for its users. Responsive and informative support can be a key factor in choosing between different wallets, and in this case, BlueWallet takes care of its users.

Conclusion

BlueWallet is an impressive wallet with an extensive set of usability features, including many of the latest advances in the Bitcoin protocol, such as Native SegWit, RBF (and CPFP), Lightning wallets and support for hardware wallets with PSBT. This makes it one of the most complete wallets on the market.

However, despite all its advantages, BlueWallet still has some disadvantages in the user interface. Although the wallet makes significant efforts to create a simple and user-friendly interface, sometimes the user experience can be confusing. Some steps in UX can be simplified or removed altogether to make the process more intuitive.

In addition, users sometimes encounter errors in the interface when flipping between wallets or when importing a wallet in view-only mode. These issues may be small, but they are still important for the overall user experience, and probably need to be fixed.

Overall, BlueWallet is a strong wallet with extensive features and a user-friendly interface, but there are some aspects that can be improved for a smoother and more enjoyable use experience.
