What is a hardware crypto wallet and why should you use one? #hardware #crypto #wallet

When it comes to cryptoasset security, self custody is unquestionably the safest way to protect your digital wealth.

Self custody simply refers to storing and securing cryptoassets by yourself, rather than relying on a third-party to do it for you. One of the most effective ways to protect your private keys, and therefore your cryptoassets, is to transfer your funds to a crypto hardware wallet — also known as a “cold wallet” solution. This is often called a non-custodial wallet, as opposed to a custodial wallet controlled by your exchange or crypto service provider.

What is a crypto hardware wallet? 

A crypto hardware wallet is a physical device that stores the private keys used to access your cryptocurrency offline. If you are still learning about private keys and the cryptography that powers cryptocurrencies, you can check out our article, How do cryptocurrencies use cryptography?

These hardware devices typically look like USB sticks or key fobs and can be thought of as portable pocket vaults that digitally store the important information needed to access your crypto funds. They cost between $50 and $250 and we recommend using one to store your crypto, especially if you do not trade daily on Kraken. A hardware wallet is like a regular pocket wallet: it is something that contains your funds, is accessible only to you, and is far more secure than keeping your funds online.

How does a hardware wallet work?

Most online crypto wallets fall under the category of “hot wallets.” These include mobile wallets, desktop wallets and web-based wallet services. All of these are connected to the internet and store their respective private keys online.

Cold wallets, on the other hand, are completely offline and only connect to the internet if and when the owner chooses to move funds onto or off of the device. No third-party trust is required. You remain solely in control of your funds in a hardware wallet, meaning you have 100% access to your funds at all times no matter what happens in the market.

When you first purchase and use a hardware wallet, a set of secret recovery phrases will be generated from within the device. Should you lose, damage or get locked out of your hardware wallet, inputting the specific recovery phrases in the correct order into a new device will recover your account and any funds you have will be accessible through the new device.

Security tips

To maximize your hardware wallet security, all cold wallet manufacturers strongly advise people to store their devices in safes, locked boxes or places that an intruder would not be easily able to access — just as you would protect any other personal item in your home. 

Be sure to keep your hardware wallet in a safe place at all times and separate your mnemonic key from the actual hardware. This ensures that even if the hardware is stolen or destroyed, you can quickly and easily access your crypto and move it to another device.
