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.
