The 25 Best Metal Crypto Wallets for Seed Phrase Storage: Examining Top Picks for 2023-2024

This phrase, which is made up of a group of words, allows you to restore your wallet and access it again in case your wallet is stolen, lost, or deleted from your device. If you lose your wallet's seed phrase, you will never be able to access your wallet again. This is why using a seed phrase storage wallet is vital.

Seed phrase storage FAQs

  • What is the best way to store seed phrases?
  • What is a metal crypto wallet?
  • Are hardware crypto wallets safe?
  • How secure is a 24-word seed?

The bottom line: Invest in a quality seed phrase storage product and hardware wallet to keep your crypto safe and secure

Every cryptocurrency wallet has a seed phrase, usually 12 or 24 words. Anyone with this phrase can access the wallet. In fact, the phrase "not your keys, not your crypto" comes from this very fact. 

While there are several ways to keep your seed phrase safe and secure, the best is to use a metal crypto wallet. Storing the seed phrase offline makes it immune to hacking attempts, which can drastically increase the security of your digital assets.

In this article, we will look at the best crypto seed storage products for 2023-2024 and examine their advantages and potential flaws so you can make an informed decision on the best way of keeping your seed phrase secure.

The Coinplate Alpha has a simple system for backing up a seed phrase. It consists of two stainless steel plates that are split into 24 sections (corresponding to the number of words in a seed phrase) with engraved letters.

 For each word in your seed phrase, you only need to punch in the first four letters using the provided tool. The reason why only four letters of each word are needed is the BIP39 seed phrase design in which only the first four letters are required to unambiguously identify the word they represent. In total, you’ll need to punch in 96 holes to back up a 24-word seed phrase.

One Coinplate Alpha wallet is currently selling for $79. However, if you buy 3 wallets, the “value pack” costs $189, which works out to $63 per wallet. This is a fairly affordable price given the quality of the product itself.

Pros of Coinplate Alpha:

  • Very sturdy construction

13. Chaindeck - Innovative seed phrase backup solution

Chaindeck is a physical seed phrase backup device with a very unique design. This backup solution consists of a deck of 100 cards. The user arranges the deck in a specific order (based on a 3-digit PIN), writes their seed phrase on the side of the deck of cards, and then shuffles the deck to encrypt their seed phrase. Setting up your back up in this way will usually take around 45 minutes if you’re doing it for the first time.

To be clear, the Chaindeck is not a metal seed phrase backup, but we’re still featuring it in this article since it’s a physical method for backing up your seed phrase. The cards are made out of professional-grade card stock, which means that the Chaindeck is not a suitable option if you’re worried about water or fire damage. 

We appreciate the innovative design of the Chaindeck and this way of backing up a seed phrase is more resistant to theft (since it takes some time to decipher the deck) than the designs implemented by most metal seed back up solutions.

It’s difficult to justify the $100 price tag of the Chaindeck since it’s just a deck of cards at the end of the day. Still, it might be worth buying if you appreciate the novelty and design of this seed phrase back up solution.

Pros of Chaindeck:

  • Innovative and aesthetically appealing design
  • Deciphering the seed phrase takes time, giving you an opportunity to respond if your Chaindeck is stolen

Cons of Chaindeck:

  • Not resistant to fire or water damage
  • Price is too high for what you’re getting

You can now hold on to your 24-word seed in an offline backup with style, defending you against flood, fire, or whatever else comes your way.

Physical offline seed word storage devices are a great way to protect your assets. Instead of writing your precious seed words on a piece of paper, which can be easily destroyed, use a physical device to protect yourself from disasters. We are also hoping this incentives you to get your seed words off of the Cloud. The Cloud might be the worst way to store your seed words as Clouds have been known to be compromised from bad actors within the company and also bad actors that social engineer their way into your Cloud account. After snooping around for a bit, they come across your seed words and steal all of your funds. That is fun for no one.

Each Metal comes with a neatly organized set of character tiles. All you do is insert the first 4 letters of each word into place, and slide the cover back. You can then rest assured that our high quality marine grade 316 stainless steel will keep your seed safe against all the elements.

Perfectly well suited for complementing your Blockstream Jade.

Bid farewell to fragile paper seed phrase recovery and embrace the stainless steel construction that optimally secures your crypto. The material used originates from the aerospace industry, known for its durability and modern appearance. Resistant to fire, water, and physical damage, the Trezor Keep Metal provides unparalleled protection. Additionally, careful consideration has been given to minimize the chance of errors. With the simple four-letter input system, a convenient marker pen, and a box for optimal grip, you can place each letter accurately time and time again.In summary: Whether you're saving for a house, children, grandchildren, or your retirement, the Trezor Keep Metal optimally protects your crypto.

The 12 words vs. 24 words backup method:The Trezor One model used a standard 24-word seed. However, the Trezor T and Trezor Safe 3 models had a standard 12 words. Therefore, Trezor has chosen 12 words as the new standard for their products. Trezor argues that a 12-word backup is almost as secure as a 24-word backup. However, almost all other hardware wallets have set 24 words as the default. Since the 24 words can be used in both situations, we sell them. There is no quality difference between the 12 and 24-word backups.

Seed phrase storage FAQs

  • What is the best way to store seed phrases?

The best way to store seed phrases is by using offline methods that prioritize security. Some common options include hardware and paper wallets. The most secure way to store a seed phrase is to engrave your seed phrase on a metal plate (what metal crypto wallets are, essentially), providing physical durability and protection against fire and water damage.

  • What is a metal crypto wallet?

A metal crypto wallet, often referred to as a "metal backup," is a physical storage solution for cryptocurrency seed phrases or private keys. It involves engraving or etching these sensitive cryptographic keys onto a piece of metal, usually stainless steel or titanium. This provides durable protection against various potential hazards like fire, water damage, and physical wear and tear. Metal crypto wallets are a secure way to back up your crypto assets and ensure their long-term safety.

  • Are hardware crypto wallets safe?

Yes, hardware crypto wallets are considered one of the safest ways to store cryptocurrency. They are designed to keep your private keys offline, protecting them from online threats like malware and phishing attacks. Hardware wallets often require physical confirmation for transactions, adding an extra layer of security.

  • How secure is a 24-word seed?

A 24-word seed phrase is highly secure when generated correctly. It provides a vast number of possible combinations, making it extremely resistant to brute-force attacks. The strength of a 24-word seed lies in the entropy it offers, which is a measure of randomness. As long as you keep your seed phrase confidential and use secure storage methods like hardware wallets, metal backups, or encrypted digital storage, it is considered a very robust and secure way to safeguard your cryptocurrency assets.
