How many words can I back up?
SATONA encodes up to 24 BIP39 words: words 1 to 12 on the front and words 13 to 24 on the back.
Is SATONA an electronic wallet?
No. SATONA is a physical backup medium. It does not store any digital assets.
Do I need to engrave the words themselves?
No. SATONA uses each word’s position in the BIP39 list to represent it in 11-bit binary form.
Is SATONA compatible with my wallet?
SATONA is compatible with recovery phrases that use the BIP39 standard.
Can I use SATONA without an Internet connection?
Yes. For a real recovery phrase, the recommended method is to download the BIP39 list and perform the conversion entirely offline.
Why use a metal plate?
A metal plate physically preserves the information needed to reconstruct your recovery phrase on a durable medium.
Should I enter my complete recovery phrase online?
No. Never enter your complete recovery phrase on a website. For real use, download the BIP39 list and work entirely offline.
Are my digital assets stored on the SATONA plate?
No. SATONA stores no digital assets or private key; it preserves only the information needed to reconstruct your recovery phrase.
