Top 3 Crypto Hardware Wallets


If you own any type of cryptocurrency or digital assets like NFTs then making sure they are secure and inaccessible to hackers and thieves should be paramount. Would you share your bank account PIN with someone else? Ofcourse not, however this is effectively what you're doing when you buy and hold crypto on an exchange like Binance or Coinbase.

Crypto transactions occur on a blockchain using public and private keys. These keys can be called the crypto equivalent of a bank account number and internet banking login details respectively. The former is something you can share with others to receive funds in your account. But your private key is more like the key to your secret safe. Whatever’s in it is only safe for as long as you do not share its key with someone else. The private key gives you access to your crypto funds that are always stored on a blockchain.

When you sign up to these exchanges, a "hot" wallet is created for you. This in turn creates your public/private key pair and interacts with the blockchains to display the right amount of cryptocurrencies you own. This is very convenient and allows you to immediately start trading without having to worry about how you're going to store your assets, however because the exchange has your private key - they are the ones who are controlling access to your funds. Even if you don't actively trade but are looking to hold assets long-term, keeping them stored on an exchange, web(e.g. MetaMask) or mobile(e.g. Coinbase Wallet) wallet is not the best idea as these are constantly connected to the internet and therefore potential targets to hackers.

There are 2 main types of crypto wallets, "hot" and "cold" wallets. Let's see the difference.

Hot vs Cold Wallets

Hot Wallets

More user-friendlyAlways connected to the internet and blockchain
Easy to complete transactionsPrivate keys stored on internet-connected application
ConvenientAlways exposed to hacks and threats

Hot wallets should be used for small day-to-day transactions, not long-term storage or holding large amounts of crypto.

Cold Wallets

More secureHarder to use
Not connected to the internet(offline)Funds are difficult to access
Impossible to hackCan be lost

Cold wallets are a better, more secure option, they oppperate in an offline mode and so cannot be hacked over the internet - just be sure not to physically lose you wallet. You can still make transactions from offline wallets all while keeping your private keys off the internet. Hardware wallets secure your keys using security element (SE) chips to reduce the possibility of attacks on the wallet. These are the same chips used to secure biometrics in your passport.
