Cryptosteel is the premier backup tool for optimal offline storage of private keys, passwords and wallet recovery seed phrases without any third-party involvement.
It 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 to survive extreme conditions and unthinkable 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.
