What are Hardware Wallets?

Hardware wallets are physical plug-in devices like USB flash drives that store the user’s private keys for cryptocurrency transactions. There is a common misconception that cryptocurrencies are directly stored within the hardware wallets, which is not entirely true.

Hardware wallets only store private keys and have specialized firmware that prevents this cryptographic information, allowing users to access and manage their funds from being accessed and stolen by hackers. But how are they different from desktop and web-based crypto wallets?

Although they are all designed to securely store the public and/or private keys for cryptocurrency transactions, hardware wallets are typically cold wallets that store cryptocurrency offline. In contrast, hot wallets like desktop and web-based crypto wallets are always connected to the internet, which makes them more vulnerable to cyberattacks.

How Crypto Hardware Wallets Work

It’s a common practice for hackers to steal cryptocurrencies by using various methods like spreading ransomware through phishing emails, slipping viruses on users’ computers, taking control of them, gaining access to their software wallets, and stealing their private keys. But that’s possible with internet-connected devices, from which hardware wallets happen to be isolated. That’s one of the main reasons they are considered the best way to secure your digital assets.

Private keys play a crucial role in symmetric and asymmetric cryptography since they represent users’ cryptocurrency ownership, open the lock to your address on the blockchain, and allow you to access your digital assets. They are randomly generated by encryption software and can’t be easily guessed. However, the possibility of them getting stolen is relatively high, so it’s vital to prevent that from happening and store them securely.

Hardware wallets often store them in a protected area of a microcontroller. Before any transaction, private keys must interact with separate devices such as smartphones, PCs, laptops, and more.

Before purchasing a hardware wallet, there are several things you must consider.

    • They come in all shapes and sizes with different inputs, such as USBs, Bluetooth, cameras, etc. Consider buying one that is easy to hold and carry with you.
    • Some hardware wallets only support Bitcoin, while others allow storage of 1000+ cryptocurrencies and tokens, which is a big difference. Check if the hardware wallet you’re about to purchase is compatible with your devices and which operating systems it supports.
    • Not all hardware wallets have backup features or offer two-factor authentication, one of the top features they must have.
    • Make sure to look deeper into the interface and how you can interact with your wallet and access your funds.

What are Hardware Wallets' Benefits

Hardware wallets become more and more popular with each passing day. They have maintained a good track record since they first launched and continue growing in popularity because of these specific advantages.

Hardware wallets become more and more popular with each passing day. They have maintained a good track record since they first launched and continue growing in popularity because of these specific advantages.

  • Super security

Hardware wallets provide the safest storage for your private keys. Since they are not connected to the internet and don’t release private information anywhere near a computer, your private keys will not be hacked or copied. You can also set a PIN and an optional passphrase as an additional layer of security to protect your wallet from being physically used by other people.

  • Immune to computer viruses

Most viruses are designed to attack software wallets connected to the internet. Hardware wallets are immune to viruses that target private keys and send them to hackers.

  • Wallet-to-wallet trading

Some platforms allow users to trade assets straight from hardware wallets while sidestepping the exchange, which saves a lot of time.

  • Many assets, one location

Some hardware wallets make it possible to manage multiple cryptocurrencies simultaneously. Therefore, hardware wallets will do the job for you if you want to work with different blockchains like Bitcoin and Ethereum on the same device.

  • Transaction verification

You can sign and verify transactions through your hardware wallet, reducing the possibility of anyone accessing your device and digital currencies and making transactions without you knowing.

How To Use a Hardware Wallet?

To set up your hardware wallet, you’ll need to connect it to your PC or smartphone using a USB cord or Bluetooth connection and follow the prompts until you get to the PIN code.

Your hardware wallet will generate your PIN code or seed phrase, a list of 12 or 24 “backup words” in a particular order that allows you to access your hardware wallet. This will help you restore access to your keys if your hardware wallet gets damaged or stolen by someone else.

It would help if you memorized that seed phrase to retrieve access to your funds. Remember never to take a picture of it or keep it on your phone or computer. Write them down on paper, save the form in a safe place, or only rely on your memory.

How To Manage Cryptocurrency Using Hardware Wallets?

If you want to receive cryptocurrency, you can use your public crypto wallet address. However, you must communicate with your device through its proprietary apps or websites to trade or send crypto directly from your hardware wallet.

Hardware wallets allow signing transactions physically without the internet. Even when connecting with computers, they never release your private information from the hardware device.

To sign transactions, you’ll need to download the app of your hardware wallet on your PC or smartphone that will communicate with your wallet and provide you with a wallet address, which you must use to send and receive crypto. You will receive unsigned transactions through it, sign them on the hardware wallet without using the internet, then send them back to the program.

Your hardware wallet will generate a “signature”, a transaction message encrypted with your private key, through which you prove your ownership of your private key. Input your PIN code on the device to confirm and verify the transactions, and wait for the confirmation

Hardware Wallet Security Risks

Although hardware wallets are much safer than other options, several things can still go wrong and make them vulnerable to attacks. With that in mind, you need to consider the potential security risks before putting your trust in hardware wallets.


The possibility of hardware wallets getting tampered with during shipping is relatively high. It has happened a lot. Many people have received fake wallets, which resulted in their vital private details getting phished by hackers.

Hardware wallet manufacturers have started using holographic stickers to prove that the wallet was never opened. They have also created web pages allowing customers to check their wallets’ security.

Buying hardware wallets straight from a manufacturer’s website or from trustworthy vendors and technically competent security experts with a good reputation can reduce the risk of wallets getting tampered with. You can also open the device and check for extra elements attached to the circuit board before using it.

Preconfigured Seed Phrase

Bad actors have found a new way to access users’ private keys by sending them already existing seed phrases.

As we’ve already mentioned, when you set up your hardware wallet, it randomly generates a sequence of words known as a seed phrase. The keyword in the definition of the seed phrase is randomly-generated. Therefore, if you receive your hardware wallet with an instruction to initiate it with an already existing preconfigured seed phrase, don’t use it.

Insecure RNG

Although private keys’ security is mainly based on these randomly generated seed phrases, it’s not easy to verify the true randomness of hardware wallets’ RNG (Random Number Generation), which may become insecure after a malicious weakening. Bad actors can recover and recreate the seed phrase generated by an insecure RNG in a few hours.

Imperfect Implementation

The security of your wallet mostly depends on the hardware or software implementation, which is almost impossible to prove. If there are flaws in the hardware or firmware, it may be possible for attackers to gain access to your keys.

Evil Maid Attack

In our case, an evil maid attack refers to an attack on a hardware wallet, resulting in the device being altered in an undetectable way. Once bad actors physically access your device, they can install malware on it if it’s not protected by a passphrase or replace it with an already infected device that looks the same as the real one. If your wallet has PIN protection, you can recover your assets and send them to a new wallet.
