Crypto Wallet Hardware: What is it, how does it work? | PortalCrypto

Hardware wallets are physical devices used to store digital keys to crypto assets and are one of the most secure methods of storing cryptocurrencies. Read on to find out what they are, how they work, and why you should use hardware wallets.

What are hardware wallets?

A hardware wallet is a device for storing digital assets offline. Hardware wallets, also known as cold wallets, are offline devices used to store access data for cryptocurrencies or digital assets. They often resemble the USB drives we all know. Hot wallets consist of different types of sub-wallets such as web, mobile and desktop wallets.

While storing your private key or accessing information in hardware wallets can protect your assets from theft, it can be risky if you don’t have a backup. Additionally, users should purchase hardware wallets directly from the manufacturer rather than considering second-hand wallets to prevent devices from being tampered with, which may lead to inefficient use.

How do hardware wallets work?

Hardware wallets require a private key to perform offline transactions. Users must connect it to their computer or other devices to access the private key. A transaction always starts offline using a USB stick, CD, paper or other offline devices. The transaction data is then connected online and securely encrypted before being transmitted over the network. It is important to note that the private key is not transferred to the server during the encryption process, so it is not accessible to hackers.

Advantages and disadvantages of hardware wallets compared to hot wallets


  • Hardware wallets are designed to prevent data intrusion as the private keys of digital assets are well protected even when connected to computers or Bluetooth devices.
  • Web wallets are considered the least secure because they are more exposed to cybercriminals and therefore cybercrime.

Easy to use:

  • Hardware wallets are less convenient to use than hot wallets, as an internet connection is required before transferring currency data to hot wallets for making transactions.
  • Hot wallets are easy to use online. Users do not need to switch between offline and online modes to transact.


  • Hardware wallets are sold at relatively high prices. Therefore, it may be more suitable for more experienced investors who hold a large amount of cryptocurrencies.
  • Hot wallets, on the other hand, are free to use, but are designed to store a smaller amount of coins.

Are hardware wallets safer than hot wallets?

The fact that hardware wallets store digital assets offline makes people believe that they are a safer choice. However, there are a few additional factors to consider before deciding on a type of wallet to use, for example, users who need to track their assets more closely may choose hot wallets as they can be directly connected to the stock exchange. trading, which makes it easier for traders to users to complete transactions.

In short, hardware and asset wallets are good options for storing investors’ access keys to their cryptocurrencies. Trader investment and lifestyle factors should be considered when choosing the best storage method.

Hardware Wallet Security

As mentioned above, hardware wallets are designed to store private keys. They are small, portable and easy to use. The reason they can prevent cyber crimes is because there is no internet connection.

Thus, digital wallets that store security codes and keys on the server are more at risk of being hacked. Meanwhile, hardware wallets store important information on a device that is not accessible to most cyber criminals.

Hardware Wallet Risks

While it is true that hardware wallets are indeed extremely secure, they still come with some risks that you need to be aware of in order to protect your funds. Some of the less reputable wallets may have certain design flaws or software bugs that make them vulnerable to unauthorized access. This is why you should always aim to buy only the best hardware wallets.

It is also possible that the material will be exchanged during its delivery to you. Secure wallets can be replaced by others without your knowledge, or a backdoor is inserted into your real device. If you receive a package that appears to be tampered with in any way, please contact the product manufacturer immediately for advice.

Key Benefits of a Hardware Wallet

Hardware wallets store users’ private keys securely when they are offline. Keys are stored on the device’s microcontroller and cannot be exported in plain text. These wallets have the distinct advantage of being completely immune to potential viruses or hacks where software or exchange wallets are considered vulnerable.

When you need to connect your online wallet, transfer or exchange cryptocurrency, you can log in through a secure system that allows you to validate all device operations. Communication is also secure and encrypted, so your private keys never come into direct contact with potentially dangerous software.

Is it necessary to have a hardware wallet?

Most cryptocurrency exchanges only allow users to trade after registration and lengthy KYC processes. Users can store their digital assets in the wallet of a given exchange, so it is not always necessary to search for additional wallets. However, hardware wallets or cold wallets are great options to increase the security of your assets. More importantly, hardware wallets can reduce the risk of data intrusion and many types of cybercrime, as well as increase security effectiveness.


Hardware wallets are not suitable for inexperienced users. As a rule, a hardware wallet is complicated and includes relatively complex operations and settings that are not suitable for beginners. A hardware wallet user should regularly back up their information in case of loss, theft or destruction.
