What is a Cold Storage Ethereum Wallet?

Cold storage ethereum refers to ether (or the private keys for those funds) that is stored offline.

Ethereum, ERC-20 tokens and other altcoins are more popular than ever, but that popularity has also garnered the attention of hackers.

Unfortunately, cryptocurrencies like ethereum cannot be stored in a traditional bank, so owners of ethereum do not benefit from the safety and insurance that a bank provides.

This means that the owner of ethereum is solely responsible for protecting their own digital funds. This is where cold storage ethereum comes in.

Storing your ethereum offline keeps it safely outside of the reach of hackers. Cold storage options include:

  • USB drive
  • Paper wallet or QR code
  • Physical wallet
  • Hardware wallet

A common concern for someone using a USB drive, paper wallet, QR code, physical wallet or sound wallet is that if any of these items fall into the wrong hands, the private keys are extremely vulnerable.

Because of this, many people who use cold storage methods like a paper wallet or USB drive store that device in a safe deposit box for added security. However, doing so makes it more difficult for them to access the ether when they need it.

A hardware wallet, on the other hand, is widely considered the safest form of ethereum cold storage, and provides ease of use as well.

What is an Ethereum Hardware Wallet?

A hardware wallet stores your digital funds’ private keys in an offline hardware device that you can connect to a computer or smartphone to make transactions.

As cryptocurrencies like Ethereum and Bitcoin have become more common, hardware wallets have become popular as safe, functional, and easily accessible cold storage solutions.

Ether that is stored in a hardware wallet is protected even if the computer you are using falls victim to a hacker or a virus.

The private keys stored on a hardware wallet also can’t be transferred in plaintext, protecting you from malware.

Because hardware wallets require a PIN code to access, it is difficult for a thief to access funds from it even if they steal the device.

ERC20 tokens can also be stored on a hardware wallet, but must be accessed via a software wallet such as myetherwallet.com.

While there are, in theory, ways that a hardware wallet could be compromised (a bug in the firmware or software, a corrupt shipping process or production/assembly system), at the time of this writing, there is no record of a theft from a hardware wallet. Because of this, hardware wallets are commonly accepted as the safest means of cold storage ethereum.

Meanwhile, with easy connectivity via smartphones and computers, hardware wallets provide easy access to your funds when you need them. Hardware wallets seamlessly blends security and protection with ease of use and accessibility.

Let’s take a look at some of the best ethereum hardware wallets on the market.
