      Backup any 24-Digit alphanumeric password into a grade 304 stainless steel plate which creates a cold and permanent offline backup. This product works with a single center punch tool.

      The Phrase S is unmatched when it comes to stealth and sophistication, it offers added discreteness. Don't underestimate its toughness! It's made to last for a lifetime.

      Unlike our other backups, the steel doesn't have direct laser etched guides, instead it works a removable vinyl sticker. After you have punched your password, you may remove the vinyl and use the recovery acetate to decode it.

      Got any questions?

      The main goal is safety and longevity. By stamping/punching your seedphrase into a piece of grade 304 stainless steel, you are minimizing the risk of an accident that may occur with a piece of paper, such as a natural disaster that may turn your key illegible. It also lowers the chance of hacking: the nature of the backup (a physical object) implies it is not reachable via the Internet or any other digital medium. You immortalize your crypto wallet with a deep cold state solution.

      Why? This method of backup works extremely well for two simple reasons: It makes use of a standardized method (BIP39) and utilizes a high quality material that can last for hundreds of years (stainless steel).

      How? By stamping/punching your seedphrase (which is essentially a very long password that represents your private key) into a super long-lasting piece of steel, you are actively creating a timeless copy of your coins and securing them forever.

      No. You never have to share your key with anyone at any point of the process. We provide the backup solution and the tools needed for each customer to complete it in their own privacy. Our products are 100% trustless and non-custodial. (Privacy)

      This grade of steel is highly durable and prevents any kind of rust/corrosion. It will also withstand high temperatures (1450°C/2642°F) and shock.

      The only way you can leave a mark into the steel is by using specialized tools like a hammer and hardened steel stamps.

      We have put our products to the test:

      Nothing happens. The status of our business does not affect the functionality of the products we sell in any way. The BIP39 standard is open to the public and we just provide a backup solution of it. Once you setup your backup you are the only and true owner of it.
