Rating of hardware wallets for cryptocurrency: which one to choose in 2024

What is a private key

When a user registers an account with the service, they are provided with two pairs of keys: public and private. They are used to generate the address and sign transactions that confirm the ownership of coins. The password is a set of characters that allows access to the account. If it is obtained by someone else, the owner will lose his savings. It can only be recovered using a mnemonic phrase.

The digital signatures and private key required for payments are generated through the device. It is important to write down the initial word (recovery phrase) on a piece of paper and keep it in a safe place.

How hardware wallets work

To receive coins, you need to generate an address. The process will start in the background, then the identifier is displayed. It is passed to the sender.

If coins need to be sent, the app creates a raw transaction waiting for approval. The unsigned transaction is sent to the hardware cryptocurrency wallet, where it is confirmed with a password. The signature is then returned to the computer, and the transfer is broadcast on the network.

The private key is stored in the device and is not visible to the PC it is used with. This provides security. If the vault breaks, the owner can apply a mnemonic phrase in the form of a 12 or 24 word entry.

Security

Since the introduction of the first hardware crypto wallet for Bitcoin, there have been no reports of hacks or funds disappearing. Hypothetically possible risks are described below:

• Poor software implementation of the random number generator (RNG), which is used to create cryptographic keys for encrypted data transmission. Attackers can crack the keys created by an insecure sensor.
• Bugs in the software itself lead to the disclosure of sensitive information to third parties.
• Introduction of backdoors (malware) during the production or delivery phase.

Limitations

Hardware vaults lack the flexibility of online applications because you have to carry the device with you for every transaction, and connect it to a desktop PC. They are not free and require an investment. If you lose your wallet, PIN or initial recovery password – you won’t be able to access the cryptocurrency.

Sizes

Standalone wallets come in different sizes. Some are 10 centimeters long, others look like flash drives. They are convenient for storage and transportation. Modern models are similar to mini-computers. Individual types are equipped with a touch screen, one or more buttons for convenient operation.

Differences from other type of storage

To use a hardware wallet for cryptocurrency, you need to connect it to a computer, enter a pin code, a passphrase. Carrying out operations is possible only when the device is active. It does not require the installation of additional programs.

Unlike hot, cold wallets store private keys not on the server, but on a special chip of the device. Only the owner has access.

Standalone storage is more difficult to hack, as it is not easy to gain physical access to it. If the device ends up in the hands of an attacker, he will need to enter a pin code and a mnemonic phrase that are known only to the owner. Hot cryptocurrency wallets have inherent vulnerabilities. Although their databases are safe, there have been cases of hacker attacks on such applications and programs, after which users lost assets.

The cost of individual models reaches up to 250 dollars. However, you can choose to buy a cryptocurrency wallet or create a digital vault without investment. Most of the software is free, provided either by third parties or by the cryptocurrency developers themselves.

Ledger

The company is best known for two types of wallets. Leder Nano S is the first model. It has a secure operating system BOLOS, supports 1800 cryptocurrencies and various tokens.

The Nano X version is more popular. This is the second generation of hardware vaults. It is easy to work with, as navigation is done with buttons (left-right), pressing both at the same time acts as “Enter” to confirm transactions.

Security is provided by its own operating system. Personal keys are isolated on a secure chip. A PIN code is required for access. Transactions and changes made to settings are confirmed by pressing physical buttons. The recovery phrase consists of 24 words. This makes it difficult to compromise the device.

The features of the Ledger Nano X are summarized in the table.

Trezor

Developed by the Czech manufacturer SatoshiLabs. Two models are distributed. Trezor One was released in 2011. It has a deterministic structure, which means that it can store an unlimited number of keys (BIP 0032/BIP 0044). It has fewer features compared to the next version.

Where to buy a wallet

Buy hardware storages should be purchased only from official manufacturers and distributors. So you can be sure of the originality of the product.

The features of purchasing autonomous wallets are presented in the table below.

Potential vulnerabilities

Autonomous storage is characterized by reliability, but has hidden vulnerabilities. The main ones are associated with the actions of hackers, unscrupulous suppliers, viruses.

Hacking

Cryptocurrency owners prefer hardware wallets to software wallets because of increased reliability. They offer protection against hacking through a PIN code, which after 3 incorrect attempts is blocked and requires you to enter a seed-phrase. Therefore, it is virtually impossible to hack into such a vault.

Fraudulent vendors

An unscrupulous distributor can counterfeit the device before sending it to the buyer. To protect the authenticity, official manufacturers use a holographic sticker. Its integrity shows that it has not been opened.

You can not use an already configured hardware cryptocurrency wallet. The owner must independently enter the pin code, password, copy the cid-phrase, make a backup copy.

When buying a hardware wallet, it is necessary to make sure that the protective seal is intact.

Compromised cid-phrase

A cryptocurrency wallet must generate a recovery passphrase when set up by the user. It cannot be obtained in advance or with the device.

If the phrase is compromised by a hacker, the hacker will recover the vault and the owner will lose coins.

Viruses

Hardware wallets offer an extra layer of protection against various cyberattacks, malware intrusions on any personal computer. You need to keep your secret key and a copy of it in safe, secure places.

Regardless of the type of storage, there is malware that allows you to change the recipient’s address to an identifier belonging to the attacker. Multi-factor verification will avoid the problem.

Evil maid

This is an attack that physically attacks a device that has been left unattended by the owner. Since the case can be disassembled, it is necessary to establish whether it has been tampered with. Special holograms or epoxy are used for this purpose.

If the owner discovered that the device was damaged, it is necessary to enter a mnemonic recovery phrase to send coins to a new vault with a different password.

5-dollar attack

The name of the vulnerability is associated with physically threatening the owner of an offline vault with a wrench equivalent to the value of $5.

Some cryptocurrency wallets have additional layers of protection added after the PIN. The user can customize the service so that different passwords display separate accounts. For example, do not disclose the amount contained in the account, but show only a small part of the coins.

How to make a hardware wallet for cryptocurrency from a USB flash drive

This method can be used under long-term storage. To create a cold wallet for cryptocurrency on a flash drive is not difficult. It is necessary to consider the process with the Electrum application step by step:

1. Prepare a USB drive with a size of 8 GB or more.
2. Download the open source operating system Tails.
3. Download the Electrum application to your computer. It takes up a small amount of memory.
4. Install the OS on a flash card. This is recommended for maximum reliability.
5. Download the application to the operating system on a USB flash drive.
   

   It is recommended to use this flash drive only as a physical cryptocurrency wallet without downloading other programs and files.

6. Select the type of protection: standard, two-factor, multitasking.
7. Disconnect the computer from the Internet.
8. Conduct further installation offline.
9. Take out the flash drive.
10. Reboot the PC.
11. Check the operation of the operating system without the Internet.
12. Connect the USB to the computer.
13. Go to the flash drive folder and open the service installation program. It will not be able to connect to the Bitcoin network, but it will create a new storage.
14. Conduct a standard installation. The new application will be placed in the OS of the USB drive.
15. Create a strong password.
16. Record and then duplicate the generated 12-word recovery passphrase.

After setting the password and writing the seed phrase, the new physical wallet for cryptocurrencies and BTC on the flash drive is ready to go. Now you can accept and send coins.

If everything is done correctly, a flash drive for storing cryptocurrency will not be inferior to hardware devices in terms of reliability. If you install the application without a boot system, it will have a lower level of security.

Summary

With offline storage, digital assets are under the control of the user. They are protected through pin code, password, recovery phrase.

When choosing a wallet, you should consider the price, list of supported coins, interaction with digital applications and other features.

Regardless of the choice of storage should:

• Make copies of the cid-phrase and place it in a safe place: it serves to recover keys in case of theft, breakage, loss. You should keep a copy in a secure location, preferably not in the cloud or on your computer’s disk.
• Verify addresses before confirming transactions: although attackers cannot remotely hack the hardware vaults that sign bitcoin transactions, they use other methods. For example, cryptocurrency malware changes wallet addresses copied by the user to the clipboard.
• Only buy the device from an official vendor or manufacturer.
• Remember that the seed phrase is generated by the storage itself and should not be received when it is delivered.
