What is a hardware wallet?
A hardware wallet is a physical vault designed to offer safe storage for your cryptocurrency private keys. These specially designed hard drives usually connect to your computer or smartphone via USB and, because you keep them offline, provide cold storage for your coins and tokens.
Hardware wallets contain a range of security features to protect your digital currency keys.
They’re protected by a PIN and often include other security measures, such as a screen for viewing transaction details and buttons on the device for manually verifying transactions.
There are essentially two separate parts to a hardware wallet. The first part is a desktop, mobile or web client that’s connected to the Internet and performs nearly all the basic features of an ordinary hot wallet.
This software wallet creates the transactions but cannot sign them – which is where the second part, the physical hardware wallet that contains your private keys, comes in. The transaction must be sent to your offline hardware wallet, verified by you and signed by the device before it can be completed.
Hot or Cold?
A hot wallet
is any wallet that has an active connection to, or is hosted, on the Internet. These wallets are more abundant than cold wallets and are often more user friendly. Thanks to their connection to the Internet, moving funds in and out of these wallets is quick and easy. Unfortunately, this ease of use also comes with disadvantages, such as making them susceptible to hackers, phishing scams and other vulnerabilities. Examples of hot wallets include those offered by exchanges or web wallets such as MyEtherWallet.
A cold wallet refers to any wallet stored offline. Cold wallet storage can refer to a number of methods, such as creating a paper wallet with a QR code, storing a wallet on an air-gapped computer (disconnected from the Internet) or using a hardware wallet. While considered more secure than a hot wallet, cold wallets are often slow to use, require a physical object and can be damaged in ways hot wallets cannot. Hardware wallets are a particular type of cold wallet, popular for their additional security and redundancy features.

Why use a hardware wallet?
Why would you want to choose a hardware wallet over a desktop or online wallet? The main advantage of hardware wallets is simple: they’re widely considered to provide the most secure storage option for crypto coins and tokens.
Unlike web wallets and desktop software wallets, which are exposed to risks like hacking, malware and phishing scams, hardware wallets provide offline storage. Your coins will be safe even if your computer is hacked – your private keys are stored securely in your hardware wallet, not on your PC – and lost or stolen wallets are PIN protected.
In addition, if you lose your wallet, you can restore your coins by using your recovery seed. This is a unique passphrase that you can write down and store in a separate place. This recovery seed allows you to recover your funds if something goes wrong.
There have been a myriad of well-publicised examples of hackers and cybercriminals stealing coins from exchanges and hot wallets, so opting for a hardware wallet is all about peace of mind. If you’re planning on storing a large amount of crypto for any length of time, moving them into a hardware wallet could be well worth your while.
How to choose a hardware wallet
If you’ve decided that offline storage in a hardware wallet is the best option, the next step is actually choosing a wallet. There are several reputable options available, so make sure you consider the following factors when deciding which one is right for you:
Security features. How secure is the wallet and what features does it offer? Is it secured by a PIN? Does it include its own screen? Can you verify transactions by manually pressing buttons? Have there ever been any reported instances of security breaches involving the wallet?
Ease of use. Consider how easy the wallet is to set up and use. If you don’t completely understand the processes involved, there’s always the very real risk of losing some or all of your funds. With this in mind, make sure the wallet makes it as simple and straightforward as possible to keep track of your crypto holdings.
Supported currencies. Check the fine print to make sure all the coins and tokens you want to store are actually supported by the wallet you’re considering using.
Supported operating systems. Is the device compatible with the operating system you’re running on your computer or smartphone?
How you actually access your crypto. Hardware wallets usually come with their own hot wallet, which is typically a browser extension or web wallet. Many devices also allow you to interact with your crypto holdings using a third-party wallet – for example, if you were storing Ether (ETH) on a Ledger Nano S, you could manage your tokens using either the Ledger Wallet Ethereum app or the third-party wallet MyEtherWallet.
Back up and restore. Read up on the process required to back up your wallet and restore your coins if something goes wrong. Is this easy to do and will it increase the level of security for your funds?
Price. This is an important factor for many as hardware wallets are not free. Compare the prices of competing wallets, including exchange rates and shipping costs if buying from an overseas provider, to get a better idea of which option offers the best value for money.
Portability. This may not be an important feature for all users, but if you want to transport your wallet with you, consider how easy it would be to carry around on a day-to-day basis.
Independent reviews. Do your research to find some independent reviews of any wallet you’re considering. What do those reviewers list as the wallet’s pros and cons? What problems (if any) have they had when using it and do they recommend it?
By considering these important features, you’ll have a much better idea of which hardware wallet is right for you.

More tips when using a hardware wallet
Keep the following tips in mind to help ensure the security of your crypto coins and tokens:
No wallet is 100% secure. If you want to ensure the safety of your funds, the buck stops with you. The most secure wallet in the world is useless if you don’t properly follow wallet set-up or security instructions, so exercise caution at all times.
Only buy from a reputable seller. Only buy hardware wallets direct from the manufacturer or authorised reseller since buying a second-hand wallet puts you at risk of hacking and theft. For example, in one well-publicised case, a Reddit user reportedly had his life savings stolen after buying a used Ledger wallet to store his crypto.
Keep private details private. You should never disclose your hardware wallet’s secure PIN and your crypto private keys to anyone.
Don’t lose your recovery seed. You need your recovery seed to access your crypto coins if your wallet is lost or stolen, so make sure you write this seed on a piece of paper and keep it safe. Better yet, write it on two or three pieces of paper and keep them all in separate but secure places.
If you’re smart about how you manage your funds, a hardware wallet can provide safe storage for your digital currency. The initial outlay of NZ$100 or more may be a stumbling block for some, but if you value peace of mind then this upfront cost could be well worth it.
