BIP39 describes the implementation of a mnemonic sentence.
It consists of two parts: generating the mnemonic and converting it into a binary seed.
The English-language wordlist for the BIP39 standard has 2048 words, so if the phrase contained only 12 random words, the number of possible combinations would be 2048¹² = 2¹³², and the phrase would have 132 security bits.The first 4 letters of each word be used to complete the full word. You can search your full word via the this link.

If you misplace your private key or your hardware wallet becomes damaged, having a recovery seed phrase will allow you to regenerate your private key and get your crypto back. Otherwise, without a backup, your chances of recovering your lost coins are pretty slim.
A seed phrase (also known as mnemonic code or mnemonic seed phrase) is a collection of words that allow access to a cryptocurrency wallet and shouldn’t be confused with a “private key”. With that in mind, here are the 25 best metal seed phrase storage options in the market:
The Billfodl is hands down one of the best options for seed phrase backup. This stylish and portable case, built out of solid steel, is designed to resist fire and water with ease. According to the spec sheet, Billfodl is capable of withstanding temperatures that are more than double that in an average house fire, can resist shocks of up to 1 million volts, and is designed to be completely immune to rust.
These features make Billfold virtually indestructible and if stored in a secure location, one of the best ways of keeping your seed phrase secure. In addition, Billfodl is very easy to set up – simply slide the first four letters of each of the 24 mnemonic seed phrase words into the metal case. Once done, close the case by screwing in the top screw.
Billfodl, used in combination with a quality crypto hardware wallet such as Ledger Nano X, for example, is the premier crypto security solution your money can buy in 2023-2024.
Cryptosteel Capsule is another premium seed phrase storage solution sold by Ledger, the leading cryptocurrency wallet manufacturer. It offers similar protection as Billfold, just in a different form factor. To set up the Cryptosteel Capsule, you need to slide the first four letters down the central rod. You can use an included separator to separate each of the 24 recovery words.
Cryptosteel Capsule is made out of 303 and 304-grade stainless steel and is capable of resisting temperatures of up to 2500 °F (1400 °C). Moreover, the all-metal capsule can withstand up to 150,000 N of pressure.
To accomodate the needs of cryptocurrency users who take their security very seriously, Trezor sells a bundle of five Cryptosteel Capsules in combination with their flagship crypto hardware wallet, Trezor Model T.

Blockplate 24 is a rugged metal wallet that is engineered to safeguard seed phrases. It is a low-tech but highly durable product, similar to Steelwallet, and can withstand prolonged use without succumbing to wear and tear. The wallet is composed of a double-sided stainless-steel plate, on one side it has a 24-word seed phrase engraved, and on the other side, an engraved QR code.
The plates of the Blockplate metal wallet are constructed of 304 grade hardened stainless steel, a material that is highly resistant to water, fire, and physical damage. This makes the wallet an effective tool for protecting your private keys from a wide range of potential threats. One thing to note is that the Blockplate metal wallet does not come with an automatic center stapler.
X-SEED Pro is a highly durable and secure device made by SecuX, engineered to safeguard seed phrases and private keys. It is designed to withstand a wide range of environmental factors, including water, weather, moisture, and fire, and can withstand temperatures of up to 1454°C or 2649°F.
The wallet's stainless-steel plates are treated to resist corrosion, ensuring that the engraved letters remain legible and remain intact in any climate. The wallet's thickness of 6mm makes it resistant to high-pressure impacts and will only break under severe impact. The wallet boasts a sleek and compact design, making it easy to carry and transport. The X-SEED Pro metal wallet is priced at $89.
Coinplate Alpha is a metal seed phrase backup device constructed out of German stainless steel. This ensures that the device is resistant both to water damage and corrosion, and can withstand temperatures up to 1,400 degrees Celsius (2,500 degrees Fahrenheit).
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.
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.

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.
All specifications of the Trezor Keep Metal are described below:

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.
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.
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.
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.
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.
