About BIP39 Books
We believe that securing your Bitcoin should not require trusting digital systems.
Our Mission
The Book Cipher is a well-established method: encode information as references to words in a shared book. No electronics. No encryption software. No digital copy of what you are protecting. It works offline, on paper, with no moving parts — which is precisely what a seed backup needs.
We applied this principle to the modern problem of Bitcoin seed phrase backup. The result is BIP39 Books: real, readable books that each contain all 2,048 BIP39 seed words, woven naturally into the text. You encode your seed as a short list of page-line-word numbers. The numbers stay separate. The book sits on any shelf. Nobody knows what you have protected.
No digital footprint. No suspicious hardware. Hidden in plain sight.
