Hardware Wallet Definition

A blockchain hardware wallet is a small physical device that crypto investors use to store their assets. Furthermore, a hardware wallet offers some of the best preventative security measures against falling victim to a hack. Also, hardware wallets allow users to store a variety of crypto assets offline without constant connection to the internet. Accordingly, some people refer to a hardware wallet as cold storage.

Hardware wallets come in a variety of different shapes and sizes. However, they’re all fairly small devices. Most hardware wallets are no smaller than a USB stick and not much larger than a standard credit or debit card. Ultimately, the primary utility of a hardware wallet is to provide crypto investors with the utmost security and convenience for storing their assets. 

Other Types of Crypto Wallets

Hardware wallets are a type of crypto wallet. Below, we’ll briefly differentiate the definition and use cases of hardware wallets alongside other types of crypto wallets.

Hot Wallets: A crypto wallet with a continuous connection to the internet.

  • Browser Wallet (e.g., MetaMask)
  • Mobile Wallet (e.g., TrustWallet)
  • Built-In Exchange Wallet (e.g., Binance)

Ideal Use Case: Many frequent investors and regular traders will use hot wallets to store a small percentage of their holdings. Although hot wallets carry increased risk with an internet connection, they offer convenience, flexibility, and the general consensus that hot wallets offer sufficient security for trading. The majority of the exploits of hot wallets are not a result of security failures from within the wallet. Instead, hackers have gained access to users’ information using phishing emails or other malicious attacks.

Different Types of Crypto Wallets.

Cold Wallets: A crypto wallet that does not require any or continuous access to the internet, either as a physical device or downloaded software.

  • Hardware Wallet (e.g., Ledger)
  • Desktop Wallet (e.g., Electrum)
  • Paper Wallet

Ideal Use Case: Cold storage wallets offer the best security for preventing hacks and theft of funds. In addition, unlike some hot wallets, cold wallets will always be non-custodial. This means that users have control and access to their funds at all times. Traders and investors tend to use cold wallets for storing the majority of the funds they won’t use or need for trading. A common practice amongst traders is trading with a set amount of funds in a hot wallet and transferring any profits straight into cold storage.

Another analogy of hot and cold wallets is thinking of them as your regular wallet and bank account. People carry small amounts of cash around for spending but keep their life savings in secure storage.

Top Hardware Wallets

When comparing the security features of different cold storage wallets, hardware wallets will often come out on top. Also, many hardware wallets use two-factor authentication (2FA) as an additional precautionary measure. Below, we’ll discuss some of the top physical hardware devices for crypto storage currently available on the market.

Ledger SAS

Ledger SAS launched its Ledger device series in 2014. Its Ledger device range is arguably the most popular hardware wallet selection available, with substantially more Google and Amazon reviews than other leading hardware wallet brands. In particular, Ledger Nano S was one of the first crypto hardware wallets to launch. Ledger Nano S includes a micro-USB cable to connect the device to a desktop or laptop. Here, the users can install up to three different applications (depending on the size of the applications) and can store more than 5,500 different types of cryptocurrencies and non-fungible tokens (NFTs). At under $75, Ledger Nano S offers an affordable, easy-to-navigate introduction to blockchain hardware wallets. 

In addition, Ledger offers Ledger Nano X with Bluetooth connectivity and a much larger capacity to its sister wallet. Further, Ledger Nano X is able to host up to 100 applications alongside the same compatibility of cryptocurrencies as Nano S (5,500+). Both Ledger Nano S and Nano X are compatible with more than 50 other wallets and include a PIN code and 24-word recovery (seed) phrase. 

Ledger Nano S vs Ledger Nano X

Although Ledger is known as one of the longest-standing crypto hardware wallets in the industry, a compromise on its central management system made in July 2020 has knocked its reputation in some peoples’ eyes. None of the users’ assets or devices were directly affected. However, the hackers gained access to Ledger’s customers’ data, including names, email, and home addresses. Subsequently, some of Ledger’s customers fell victim to phishing attacks resulting in the theft of funds after that. Nevertheless, many people still choose to invest in Ledger hardware wallets for their security, ease of use, and brand identity.


The Trezor wallet range may not have the same amount of reviews online. However, the pioneering hardware wallet company was the first to invent the crypto hardware wallet. After Trezor was established by SatoshiLabs in 2013, they launched its Trezor Model One in 2014. Furthermore, the portable and convenient hardware wallet offer investors the utmost security for storing their crypto assets. Plus, Trezor promises users will be set up and ready to go in just ten minutes with their easy-to-follow intuitive user interface (UI).

Trezor Hardware Wallet Range

Being shy of $90, Trezor Model One offers more than 1,000 different cryptocurrencies storage. Further, storage of non-fungible tokens (NFTs) is also possible by installing a third-party app. Also, presenting users with a monochrome interface with two pushbuttons, Trezor Model One incorporates an innovative security protocol by SatoshiLabs, promising the highest security protocols to protect users’ funds. Trezor also offers Trezor Model T, which offers compatibility with nearly twice as many coins.

Benefits of Having a Hardware Wallet

So, now that we’ve answered “what is a hardware wallet?” and discussed some of the top hardware wallets available, let’s look at some of the advantages of using a hardware wallet.

Multiple hardware wallets from various brands such as Ledger and Trezor.

First, using a hardware wallet means that all assets are kept offline, removing the large vulnerability of an internet connection. Offline storage removes the risk of online hacks and attacks. However, it is worth bearing in mind that if you were to open a phishing email that automatically triggers a keylogging or key capturing attack, a hacker would be able to view every button pressed on your keyboard. As a result, this means that a hacker could see the password used for your hardware wallet. It is critical to the security of one’s funds to be wary of opening any suspicious emails. 

Another benefit of using a hardware wallet is the full accessibility to funds at any time. By offering more security than online hot wallets, hardware wallets are the safest place for crypto investors to store the majority of their holdings. In addition, most of the hardware wallets available are extremely portable and convenient. For people wanting to cross borders or move abroad with their wealth, hardware wallets offer a more suitable and cost-effective alternative than cash in the bank, gold bars, or other physical deflationary assets. 

Exploring What is a Hardware Wallet – Summary

Crypto hardware wallets offer the most secure form of storage for cryptocurrencies and non-fungible assets. Often referred to as “cold storage,” hardware wallets allow users to store their assets offline without a connection to the internet. Furthermore, there are a variety of different types of hardware wallets. Various brands are pioneering innovative security solutions for offline cryptographic storage, from biometric authentication to self-destruct mechanisms.
