If you’ve decided to self-custody some or all of your digital assets, it’s absolutely critical that you use every available measure of protection to safeguard your holdings. When used correctly, hardware wallets are an excellent way to store and safeguard your coins.
If you’re reading this there’s a good chance you already know what a hardware wallet is, but you may have some additional questions about how hardware wallets work or why they’re more secure than web- or software-based wallets. Ahead, we’ll explain these and many other lingering questions about these offline hardware marvels that protect your assets like no other method. If you’re not caught up on wallets, check out our deep dive choosing a Bitcoin wallet and the different types of crypto wallets available.
What are hardware wallets?
Hardware wallets securely keep a crypto user’s private keys in offline or “cold” storage, meaning they are not connected to the internet, except when a user must briefly connect them to a computer to complete a transaction (more on that later.) Software- or web-based crypto wallets are “hot”, or permanently online, which gives hackers more potential attack vectors through which to steal your funds. Because of this, hardware wallets are nearly universally considered to be a very safe option for keeping crypto assets out of the wrong hands.
Newer or more casual crypto users might not want to bother thinking about things like private keys or custody, so many cryptocurrency exchanges handle wallet services on behalf of account holders (known as a custodial wallet). However this means you’re trusting your private keys to a third party. Hardware wallets, on the other hand, allow users to take the security of their private keys into their own hands with a physical piece of equipment. Most often resembling USB thumb drives, hardware wallets have a small variance of form factors and features, and their sole purpose is to sign cryptocurrency transactions offline and safeguard a user’s private keys.
How do hardware wallets work?
Hardware wallets can be thought of as highly stripped-down computers that exist only to perform a few basic but essential functions, often containing little more than one or two buttons and sometimes a small screen. On their own, hardware wallets have no way of connecting to the internet, which means it’s virtually impossible for hackers to access their contents. When a user is spending crypto, swapping, or otherwise sending and receiving assets to/from any wallet, the transaction must be “signed” using their private key. With a hardware wallet, transactions are signed within the device itself through what’s called a crypto bridge, a simple piece of software that facilitates a hardware wallet’s connection to the blockchain.
When a user connects their hardware wallet to a PC, the crypto bridge transfers unsigned transaction data to the device. The hardware wallet then signs the transactions via the private key and uploads them back to the bridge, which broadcasts them to the rest of the blockchain network as complete. At no point in this process does a user’s private key leave the hardware wallet.
Why do people use hardware wallets?
Generally, hardware wallets are favored by more security-minded crypto users, or those with a great deal of assets to protect. This preference is a testament to the high level of security a hardware wallet offers those who wish to handle custody themselves. In fact, crypto best practices in general say you should never store large amounts of cryptocurrency in an online “hot” wallet, owing to security concerns.

Best practices when using a hardware wallet
For the most part, using a hardware crypto wallet merely requires some good old-fashioned common sense along with standard crypto security tips.
Be careful with where you get your hardware wallet
Only buy a hardware wallet from a reputable manufacturer, and it should go without saying, but never buy a used hardware wallet. Most hardware wallets include a clearly visible security feature like a holographic sticker to alert the buyer if the device has been tampered with. If anything looks out of place, do not use it.
Always triple check and test addresses when transferring large amounts of crypto
Even though a hardware wallet is considered the most secure way to store your private keys, generally accepted crypto security best practices still apply. Never send a large amount of crypto between wallets before verifying the receiving address with a small test transfer, and don’t transact with any unknown wallet addresses. If your hardware wallet has a screen, always be sure the recipient’s address on your computer screen matches up with what the wallet is displaying before initiating a transaction.
Safeguard your wallet AND seed phrase
You’ll also want to keep your hardware wallet in a safe place, as well as the recovery seed phrase. A seed phrase, also known as a recovery phrase, is a series of 12-24 randomly generated words used as an emergency backup recovery method in case a wallet is lost, deleted or otherwise destroyed. Seed phrases should be protected with the same degree of caution as your private key, as both will give whoever has them complete access to your holdings. Write down your secret phrase on a piece of paper or make another non-digital record.
Protection against the elements
Even when keeping your assets offline, you’ll need to keep them safe from the elements. Right next to hackers and scammers, fire and water are the two biggest threats to safeguarding your crypto assets. Its a great idea to use a fire and water-proof seed phrase protector like hodlr. At the very least, keep your hardware wallet and seed phrases stored in a fireproof safe.
Using multiple wallets for multiple use-cases
We mentioned that one potential drawback of a hardware wallet is its lack of accessibility for users who frequently pay for purchases with crypto. Fortunately, there’s nothing stopping you from utilizing multiple wallets. In fact, there are many benefits to doing so.
A hardware wallet can be thought of sort of like the bank’s vault, where stacks of gold bars and big bags with dollar signs on them are kept behind a giant steel door. Great for security, but not so great for spending. Using a mobile wallet in tandem with a hardware wallet gives users the best of both worlds, making it easy to access funds without compromising on security.
With a mobile app like the BitPay Wallet, users can securely store smaller amounts of crypto for everyday spending. It’s a dead-simple way for active crypto spenders to get the most out of their holdings. It’s one of many safe and convenient ways BitPay offers users looking to convert crypto to cash, along with the BitPay Card, or by purchasing gift cards with crypto from one of our hundreds of partner merchants.
Additionally, if you’re a die-hard devotee to DeFi and Web3 or just interested in exploring these growing ecosystems, a dApp-integrated wallet like MetaMask can be another useful addition to your crypto wallet stack.
