STEELWALLET is an offline backup tool for storing your recovery seed. It provides an additional security layer on top of your hardware wallet. With STEELWALLET your seed is protected against fire, water, electrical-shocks, corrosion and pretty much any obstacles nature throws at it.
What's in the Box?
When you order a STEELWALLET you will receive two laser engraved sheets made out of finest stainless A2 / ASIS 304 / SS304 steel, to punch your seed into. Also included is a metal punching pen which makes it easy to punch your seed into the sheets.
What types of private keys can be stored using STEELWALLET?
Steelwallet currently supports the BIP-39 standard which allows you to store 12,18 and 24 word seeds on your STEELWALLET. The words on the BIP-39 word list are chosen so that there is only one possible word if you know the first four letters of that word. It is impossible that there are multiple words that start with the same four letters. That’s why you only need (and only can) punch the first 4 letters of word of your seed onto your Steelwallet.
