SETUP GUIDE
Organize Character Tiles
Spread out the character tiles on a flat surface. The tiles are organized alphabetically with multiple copies of common letters.
Select Your Word Tiles
For each word in your recovery phrase, select the first 4 letters. BIP39 only requires 4 letters to uniquely identify each word.
Load the Core
Stack the character tiles onto the core using the separator between each word. Follow the numbered grooves for proper alignment.
Insert and Seal
Insert the loaded core into the capsule body. Hand-tighten the end cap securely. The capsule is now sealed.
Store Securely
Store your Cryptosteel in a secure location. Consider a safe deposit box or fireproof safe for additional protection.
FREQUENTLY ASKED QUESTIONS
Why only the first 4 letters?
The BIP39 wordlist is designed so that no two words share the same first 4 letters. Four characters uniquely identify every word, saving space while maintaining complete accuracy.
Can the capsule be opened once sealed?
Yes, the end cap unscrews for access. We recommend checking your backup periodically and resealing. The seal is not tamper-evident.
Should I replace my paper backup?
We recommend keeping both. Paper is convenient for access, while Cryptosteel provides disaster insurance. Store them in different locations.
Does it work with passphrases?
The Cryptosteel can store your 24-word recovery phrase and optionally your passphrase. However, storing both together reduces security—consider separate storage.
