The Capsule

The capsule is 102mm long and has a diameter of 16mm. Despite the small dimensions, it offers more capacity than its predecessor and similar competing products.

Cryptosteel Capsule is made of 100% high-quality German stainless steel, more precisely, steel type 303. The capsule appears absolutely robust and resistant to nearly all circumstances.

It consists of a shell and a core, which are screwed together via a deep steel thread. This thread tightly seals the tiles against external influences.

The Plates

The tiles are mainly character tiles, including all printable ASCII characters (96 different ones), including special characters and numbers.

This achieves 100% coverage for all hardware wallet recovery seeds and 99% coverage for hexadecimal strings of up to 123 characters and random ASCII strings of up to 55 characters. All characters are deeply embossed into the tiles to ensure maximum longevity.

The fonts are large and legible for better utility, and the lowercase letters are provided with a visual distinction. In addition to the character tiles, separator tiles differ in shape from the character tiles and are not punched.

You can use these to separate individual seed words. Additionally, there are some closure tiles. These serve to fix the plates at the end so that they do not slip off the core. Because the number of tiles is random, there is no need to discard the remaining tiles.

You can keep the packaging with the tiles and reuse it if you want to change or expand your capsule.

How CryptoSteel Works?

how Cryptosteel Capsule works

Your desired information can be stored in the capsule in just a few steps. First, you open the capsule by unscrewing the core. At the end of the core, you have to take off a small piece of cloth.

This contains a reminder not to forget the locked tile at the end. Otherwise, the tiles can fall off the core later when you take them out.

Then it is advisable to lay out the characters on a flat surface first. For example, this could be a random password, an unabridged 12-word hardware wallet recovery key, or the first four letters of a 24-word seed phrase.

In this case, the seed words cannot be saved entirely, but the first 4 letters are sufficient to identify a word without a doubt.

Now you can thread these tiles one after the other onto the core and, if desired, also separate the individual words with separator tiles. Finally, a clasp plate is threaded in, and the small bracket is bent through the eyelet at the end of the core.

This means that no plate can slip off the core. If you want to read out the stored information again later, it is advisable not to remove the locking plate. The free space on the capsule’s core should be enough to move the tiles piece by piece and write out the information.

This way, you don’t risk the platelets falling off the core and the information possibly getting lost.

Cryptosteel Setup

Follow these steps to set up your Cryptosteel Capsule for the first time:

  1. Firstly, Cryptosteel Capsule and its parts.
  2. Unscrew capsule: Twist the top cap to remove the core from the capsule.
  3. Remove the informative ribbon.
  4. Use character tiles to arrange your data: Select the tiles from the container provided. I recommend placing each pegment of your crypto seed code in advance on a plain surface and then sliding them easily into the capsule’s core one by one, making the overall process simpler.
  5. If your seed phrase is longer than 12 words, please use only the first four characters of each word for better space management.
  6. Use separators to segment information: You can use separators between words to separate each word on the seed.
  7. Placing the tiles into the core: After your data is set and ready to be stored, start placing them by sliding the tiles into the core. This is the perfect time to double-check your work.
  8. Place and bend the fastener at the end to hold tiles: Bend the tiny eyelet present at the end of the capsule’s core with your fingers to anywhere greater than 90 degrees. Then put it on the core of the capsule, and pull firmly to close it into place.
  9. Finally, Screw the capsule back together.

CryptoSteel Capsule Security

Cryptosteel Capsule is 100% steel – AISI 303 shell, AISI 304 core, and laminae. Grade 304 stainless steel provides the ideal combination of strength, heat tolerance and resistance to wear and corrosion.

In addition, the capsule is fireproof up to 1400 degrees Celsius. In addition, the deep thread hermetically seals the capsule, keeping the information safe even underwater.

The capsule can withstand the impact of even a 9mm bullet. Should the device be crushed, the tiles are connected by a common core, greatly improving data integrity.

It was even tested by a crypto enthusiast who used a 20-ton press with which he could bend the capsule, but no information was lost. So you can imagine the quality and strength Cryptosteel Capsule offers.

Another benefit of the capsule is its small form factor, which makes it unassuming and easy to hide.

Additionally, the codes stored in the capsule are not immediately visible at first impression.

This is useful in many situations where someone might want to quickly look at the data (cameras, airport security, showing off the device to family and friends, etc.).

You can seal the closure if you want to see if someone has read the information inside.
