Billfodl vs. Cryptosteel vs. Cryptotag Zeus comparison

A metal crypto wallet allows users to securely back up their seed phrase in case they lose access to their wallet. If you combine a hardware crypto wallet with a metal seed phrase backup solution, you can achieve a very high degree of security for your cryptocurrency holdings. 

One of the biggest reasons to use a seed phrase backup made out of metal is because these solutions can withstand much more damage than a paper backup. For example, if your house catches fire, a paper backup can be easily destroyed. Meanwhile, a good quality metal backup device is able to withstand even extreme temperatures.

When it comes to fire resistance, all the three solutions featured in this article can easily withstand the temperatures that are reached during the average house fire. A house fire can reach temperatures of up to 815°C (1500 degrees Fahrenheit), and all the metal crypto wallets featured in this article can handle a temperature of up to 1400°C. The Cryptotag Zeus is even more resistant to heat damage, as it can handle up to 1665°C

Please keep in mind that the prices cited in this article are sourced from the manufacturer’s websites at the time of writing. You might be able to find these devices for a better or worse price depending on which store you buy the device from, sales and other factors.

Prices found on manufacturer’s website as of April 2024.



The Billfodl is a seed phrase backup solution constructed out of 316 marine-grade stainless steel. The Billfodl can be used to back up a seed phrase of up to 24 words. It has 24 sections, with each fitting four characters (you only need the first four characters of each word to recover a wallet). The user simply slides in the characters in the correct order — the process is intuitive and shouldn’t take too much time.

The Billfodl can easily resist the average house fire, as the device can handle temperatures of up to 1400°C. The stainless steel that the Billfodl is made from is also resistant to corrosion, so you don’t have to worry about water damage. 

One of the best features of the Billfodl is its price. You’ll usually be able to find it for $100, which is a great deal for an easy-to-use and extremely sturdy seed phrase backup solution.

Cryptosteel Cassette

Cryptosteel Cassette

As you can probably tell, the Cryptosteel Cassette and Billfodl are based on the same design. One of the differences between the two is that the Cryptosteel Cassette is built from 304 stainless steel, while the Billfodl is built from 316 stainless steel. 

The difference between the two is that 316 stainless steel is slightly more resistant to corrosion, while 304 stainless steel is slightly more resistant to heat. However, both of these materials are extremely effective at keeping your seed phrase safe from the most common types of damage.

Unless you can get the Cryptosteel Cassette at a very good price, it doesn’t really make sense to choose it over the Billfodl. Both devices are extremely similar in terms of design and construction, but the Cryptosteel Cassette is substantially more expensive.

Cryptotag Zeus

Cryptotag Zeus

The Cryptotag Zeus differs from the previous two backup solutions featured in this article since it’s built out of titanium and not stainless steel. Instead of using letter blocks that slide into slots, the Cryptotag Zeus comes with a tool that allows users to punch in four numbers that represent each word in the seed phrase. Each word in the BIP39 standard word list can be referred to with 4 digits (there’s 2048 possible words in total).

If you are especially worried about heat damage, the Cryptotag Zeus is the best option out of the three solutions featured in this article, as it can withstand temperatures of up to 1665°C. Meanwhile, the Billfodl and Cryptosteel Cassette can handle up to 1400°C (which is admittedly still substantially higher than the average house fire).
