The seed phrase acts as a key that unlocks the cryptocurrency wallet. 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.

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.

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.

14. 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

Buy Chaindeck

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.

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

With the abundance of hacking attempts and stories of stolen digital assets, it should be obvious to anyone by now that investing in security is mandatory to keep your crypto safely tucked away from any malicious actors.

A combination of quality seed phrase storage and a cryptocurrency wallet is an unbeatable combination that offers improved security, portability, easy backup, and recovery options. In addition, it eliminates the need for third-party crypto handlers, which prevents your crypto from being tied up in the event of a cryptocurrency exchange going under (such as in the case of FTX). As such, it is a very important part of investing in crypto.

Now that you’ve examined the best seed storage options, you can check the best crypto hardware wallets to create a crypto security kit that best suits your needs. While having a quality crypto phrase storage and hardware wallet is very important, it is worth learning about other methods that can help you secure your crypto.
