The Master of All Backups



What is Cryptosteel?

And why do I need one?

Cryptosteel is the premier backup tool for optimal offline storage of private keys, passwords and wallet recovery seeds without any third-party involvement.

Our technology combines the age-old idea of engraving with a DIY assembly format and materials that are stainless, rust-free, acid-resistant and fireproof up to 1200°C/2100°F. Cryptosteel is designed to survive extreme conditions and all kinds of abuse.

With Cryptosteel, your most sensitive information is both hacker-proof and safe from the elements. There is no third party involved in keeping your recovery seed safe. And Cryptosteel beats paper, wood and corrosive metals in terms of durability. Unlike space-age materials, however, it is affordable, non-toxic and hard to detect using next-gen methods of surveillance.

Made out of one single material.
100% 304-grade German stainless steel.

Why this grade of steel over all the others? Easy. 304-grade stainless steel offers the ideal combination of strength, heat tolerance and resistance to wear and corrosion. Even in marine environments, where 316-grade steel is often selected for its extra resistance to corrosion, the bolts, screws and cogs, which require maximum resistance to both corrosion and wear, are made of 304-grade stainless steel. And of course using steel from Germany needs no explanation.

Cryptosteel is Fireproof

Fireproof up to 1200°C / 2100°F.
Cryptosteel beats fire-resistance Class 350-4.

Vault ratings measure the way materials protect what is inside a vault. So a Class 350-4 strongbox can keep paper documents intact for a minimum of 4 hours with temperatures up to 1,093.3°C/2,000°F outside the vault. For Cryptosteel, the fire can burn even hotter and longer with absolutely none of the warping that could put your data at risk. Unlike deliberate sabotage with a blowtorch, which burns 2 to 3 times hotter than most fires, a typical housefire will not distort a Cryptosteel.

Cryptosteel is Waterproof

More than waterproof and resistant to salt water and acids.
Cryptosteel stays strong as steel even under water.

Impervious to plain water and highly resistant to acids and other substances, Cryptosteel’s 304-grade stainless steel offers the optimal combination of strength and durability. While 316-grade steel and other alloys claim higher corrosion resistance in extreme-pH environments, these materials are susceptible to warping, offering less reliable protection against natural disaster. Even in shipbuilding, the parts that require maximum resistance to both corrosion and wear are made of 304-grade stainless steel.

Cryptosteel is Shockproof

Whether the danger is electric or mechanical,
Cryptosteel is built to resist accidents and attacks.

Not only will our steel survive attack and impact, but so will our build. Few materials are as impervious to lightning strikes, microwave bombs, nuclear events and vertical drops as Cryptosteel’s hard-wearing 304-grade German steel, which we use to make all product components. Thanks to our tested design and meticulous in-house assembly, the strength of our top-of-the-line material is transferred into each Cryptosteel unit.

Tested by Users and Experts

Cryptosteel is THE most secure way to back up a cryptographic private key or seed. Cryptosteels give you CCSS Level 3 compliance right out of the box, being impervious to fire, flood, static electricity and even EMPs. I truly believe there is no better alternative.
