Even the best hardware wallets are only electronic devices, and their lifespan is limited the same as with smartphones, laptops, or TV sets. For this reason, securing a recovery seed phrase backup is of paramount importance. Unfortunately, most people only create a backup to sign off on a hardware wallet setup checklist and write down the mnemonic seed phrase on… a piece of paper.

You don’t have to be an expert to notice that a sheet of paper isn’t a durable medium, especially if the crypto seed backup won’t be needed in years to come. How, in these circumstances, should we ensure proper crypto phrase storage? That’s what this article is.

What Is a Seed Phrase?

The Importance of seed phrase (alternative name mnemonic phrase) comes from the fact that it’s a combination of words that allows easy access to a cryptocurrency wallet. Every crypto wallet is based on this principle, regardless of whether it’s a Bitcoin or Ethereum wallet, or recovery seed words for any other crypto.

The hardware wallet seed generated during the first configuration is most often composed of a 12 or 24 word mnemonic recovery sequence, which is a user-friendly representation of a complicated private key. It follows that from the very beginning you should set up a safe method for seed phrase recovery, which means entering the designated words on a new hardware wallet device or app to recover access to your assets. Keep in mind that every person, who finds out the recovery seed phrase words can use them to take over the cryptocurrency portfolio. That’s why it’s crucial to implement safe seed phrase storage.

Crypto Seed Phrase – More Important than a Hardware Wallet

Though it may seem obvious to experienced crypto enthusiasts, it’s worth remembering that the seed phrase is more important than the wallet itself. If a modern smartphone lifespan is estimated to be three to five years, it’s wrong to assume that a hardware wallet will serve us for decades, and possibly centuries. A simple cracked screen will make it difficult for the user to access his or her Bitcoin. Moreover – the device could get lost or stolen.

On the other hand, if you have access to crypto recovery phrases, it only takes minutes to recover a Bitcoin wallet on a new device. To explain in simple terms, it’s like a backup key to a lock. If you have a backup key, you can enter. If you don’t – the door will remain locked FOREVER and you will never be able to get inside again. Always store your recovery seed phrase offline.

Store Recovery Seed on Paper

Writing down the sequence of words on a piece of paper is the simplest way to create a recovery phrase backup on your own. If the backup is created correctly (without third persons having access to it and ensuring the seed is never leaked online), you can consider it safe. Nonetheless, the problem of paper’s low durability is a key issue – especially in the scenario of sensitive data storage.


  • cheap
  • easy to prepare
  • easy to hide


  • low medium durability
  • zero resistance to water, fire, and other dangers

Seed Phrase Splitting

Splitting a seed phrase is a method that is often recommended by people who have no knowledge about security. We strongly advise against such an approach!

Check out the contest we organized together with Wasabi, where we proved that revealing several words from the recovery seed phrase can result in someone hacking it in no more than a few hours. That’s why it’s crucial to keep your seed away from prying eyes, locked in a device like the Cryptosteel Cassette or the Cryptosteel Capsule.

Keep in mind that there are special systems for seed splitting that actually enhance your security – one such method is the Shamir Secret Sharing method, created by the famous cryptography expert.


  • none if used by simply dividing the seed
  • boosts security when used in tandem with the seed-splitting systems like the Shamir Secret Sharing (SSS) method


  • highly dangerous
  • the more parts, the greater the risk of them falling into the wrong hands
  • false sense of security

There are, however, companies that specialize in wallet access recovery based on incomplete seeds, although this is a very costly and time consuming process. Additionally, there’s no guarantee of success.

Record Seed Phrase on Pen Drive or Storage Device

Storing a recovery seed phrase on digital media makes it easy to prepare any number of backup copies. Nonetheless, keep in mind that neither pendrives nor memory cards are designed as media for safe data storage over extended periods of time. Additional protection by encryption is a good idea to consider. Still, this doesn’t solve the issue of limited durability due to the potential for mechanical damage, water damage, or bitrot (data corruption resulting from decay over time).


  • low price
  • easy to hide


  • limited lifespan
  • lack of protection against mechanical, water, fire, and other types of damage

Protection Offered by Metal Wallet Type Devices

The Cryptosteel Capsule and the Cryptosteel Cassette are out-of-the-box type devices, meaning they’re ready to use immediately after taking them out of the package. What sets them apart from the competition is that you don’t have to invest in additional tools or spend time manually stamping characters onto steel plates or worry about the quality of the materials used to produce them.

  • these backup devices are practically indestructible – they’re fireproof, waterproof, and impervious to mechanical damage and other potential threats. This makes it a very secure seed phrase backup solution.
