How It Works – OLD

Holds Up to 10 Keys (500 Characters)

While most other products on the market only store two keys, the patent-pending Crypto Seed Capsule™ is designed to hold up to ten (10) keys, each on its own stainless steel strip. Each strip can hold a 12 word seed phrase of 4 characters each and up to 50 characters in total. By simply using two strips (100 characters in total) it can accommodate any 13, 18, 20, 24 & 25 word BIP39 recovery seed phrase.

Future-Proof & Mistake Proof
The capsule is both future-proof and mistake-proof. If your keys change or you make a mistake punching them you can purchase new strips for only $15.

Additional Storage for Valuables
There is also additional storage space inside the capsule for other valuables such as gold and silver coins; jewelry and documents. For safe-keeping the capsule is designed to fit in a standard 3” x 5” x 24” safe deposit box or a wide range of personal safes.

Crypto Seed Capsule Holds Up To 10 Keys


To stamp your seed phrase words you’ll need a metal letter stamping die kit. We recommend the ARTIPOLY Number & Capital Letter Stamp Set in the 3 mm size. You can purchase it from Amazon. You’ll also need a hammer – nothing fancy any kind will do.

With the Crypto Seed Capsule it’s easy to stamp your words. Just follow the 4 simple steps shown and listed below:

Step 1 – Insert a stainless steel seed phrase strip into the stamping guide block.

Step 2 – Position a metal letter stamping die in the center of the box on the stamping guide block. Then use a hammer to stamp the character into the stainless strip. Repeat until your entire recovery seed phrase is embossed into the strip.

Step 3 – Remove one of the end caps and insert the strips into side of capsule. Note: For extra security insert the strips with words facing inward so no one can read them.

Step 4 – Screw on the end cap to secure the strips in place.


Watch the video for a few tips on how to space your seed letters and words evenly on the stainless steel strips before inserting them into the capsule:

Letter Spacing – For optimum letter spacing on a seed word align the middle of the last letter in the word to the left side of the inner box.

Word Spacing – For spacing between seed words align the middle of the last letter in the word to the right side of the left outer box.
