supports all printable ASCII characters
passwords are protected, not visible at first glance
store your mnemonic seed in full in 123 characters
small, light, easy to hide and protect
DIY fireproof barrier seal, capsule identification possible
Fireproof up to 1400C/2500F. Shockproof. Waterproof. Stainless.
The capsule features adjustable separators and offers more capacity—123 characters instead of the 96 most other solutions provide—making it an ideal choice for password and seed phrase storage. It comes with a full ASCII character set, supporting random passwords with numbers and symbols. All of the characters are deeply stamped into the tiles to provide maximum longevity.
The capsule can securely store a random password without separators, an unabbreviated 12-word mnemonic seed, or the first four letters of a mnemonic seed made up of 25 word phrases.
The first example shows a random ASCII password stored on the core that is 55 characters long. Considering the unused space, two or more passwords can be stored, split using separators, up to 123 characters long, in total, including WIF, Hexadecimal, and Root Keys.
With the second, you can see an unabbreviated 12-word mnemonic seed phrase. With the remaining space at the top, you can store additional data including passwords, passphrases, or random ASCII strings.
The third example demonstrates a 25-word abbreviated mnemonic seed phrase. Of course, the aesthetically designed capsule is also able to store 20-word Shamir backups and 24-word recovery seeds in their abbreviated forms.
Our aim is to standardise the offline information protection system and provide a solution right out of the box. You don’t need to think or worry about buying additional materials or special tools. You don’t have to learn the hard way how painful engraving metal can be – no specific knowledge or safety equipment is needed. Simply open the pack and get started – everything you need is right there.
We use a classic, easy to read font that will be legible 10 or 1000 years from now. Hand engravings will naturally differ from person to person. Over time, you (or your heirs) may not be able to retrieve the information from a hand-written backup due to style, ambiguity, or decay. Using standardised tiles, you can change, undo, or redo the data you wish to be guarded. Should you make any errors, you can easily correct them.
The usual approach to protecting digital assets is redundant backups, but when the asset itself is of significant value and high liquidity, there is a substantial risk of a backup custodian absconding with the asset.
The cryptographic secret-sharing scheme created by Adi Shamir is an ingenious way to help protect data.
