All your questions about SATONA

No. SATONA is a physical medium designed to back up the information in a BIP39 recovery phrase in binary form.

No. SATONA stores no digital assets. The plate contains only the binary representation of the recovery information you choose to record.

The kit includes one solid-brass SATONA plate, one automatic centre punch, two tips, one premium magnetic box, one instruction leaflet and one QR code providing access to the SATONA instructions.

SATONA can encode up to 24 BIP39 words: words 1–12 on the front and words 13–24 on the back.

An exchange platform may hold the keys needed to access assets on behalf of users. With a non-custodial wallet, users control their own keys. When the wallet uses a recovery phrase, that phrase can generally restore access on a compatible wallet.

A custodial wallet is a service where a third party holds or controls the keys used to access assets. Users therefore depend partly on that provider to access their funds.

With a non-custodial wallet, users retain control of their keys and are directly responsible for protecting the recovery phrase and other information needed to restore the wallet.

A hardware wallet is a device designed to hold and use private keys while limiting their exposure to connected devices. Ledger and Trezor are well-known examples. They do not serve the same purpose as SATONA.

A hardware wallet holds and uses the private keys required for wallet operations. SATONA is not a wallet: it physically backs up BIP39 recovery information so it can be reconstructed if needed. Their roles can therefore be complementary.

If the wallet uses a compatible recovery phrase and it was backed up correctly, it can generally restore access on a compatible device or wallet. SATONA is designed to preserve that recovery information physically.

SATONA is intended for wallets that use an English BIP39 recovery phrase of up to 24 words. Check your wallet documentation before use; not every wallet uses BIP39.

The English BIP39 list contains 2,048 words, indexed from 0 to 2,047. Since 2,048 = 2¹¹, 11 bits can represent every index.

No. You mark the 11-bit binary index of each BIP39 word, not the word itself.

1 means mark the box; 0 means leave it empty. Each row is the 11-bit binary code of one BIP39 word.

Anyone with your complete recovery phrase could potentially restore the corresponding wallet on a compatible device and access the assets it protects. Treat it as highly sensitive information.

No. Never enter a complete recovery phrase on satona.fr or any other website. For real use, download the BIP39 PDF and work fully offline.

Yes. After downloading the BIP39 list, the complete conversion and marking process can be performed offline; this is the recommended method.

No. SATONA stores no cryptocurrencies, active private keys or electronic wallet. It contains only the binary representation of recovery information you chose to record.

Unscrew the conical end, insert one of the supplied tips, then screw the assembly back together. See the illustrated instructions for the complete procedure.

Centre the tip in the box, press until the punch clicks, then visually check that the mark is clear and that every 1 and 0 matches your source before storing the plate.

Record words 1–12 on the front and words 13–24 on the back, keeping the original order.

The kit QR code opens the SATONA instructions. You can also use the How it works page and download the BIP39 PDF for offline conversion.
