ORIGINAL 1.2.1 · BIT 1.2.2
New cryptograms use AES-256-GCM authenticated encryption, checking the protected content and authentication tag. This does not mean that all metadata or every older copy has this protection.
No. Protect decryption with up to six participants, requiring everyone or a threshold such as 2 of 3. This policy controls access to the secret; it does not turn a wallet into a Bitcoin multisig wallet.
Both devices process BIP174 v0 PSBTs with P2WPKH inputs and SIGHASH_ALL. They review recipients, amounts, change and fees; approval is bound to that transaction and the signature is verified. Displaying Taproot Bech32m recipients does not mean signing Taproot inputs. Private keys are not exported for signing.
Three attempts trigger a five-minute pause that persists after power loss. This limits attempts on the device, not offline attacks on an exported copy. Use strong credentials and protect your backups.
After decrypting a compatible older unauthenticated copy, create a reinforced version while retaining the secret, credentials and participant policy. Original saves it to NFC; BIT returns it over USB-C and retains biometric templates where applicable. Verify the new copy before retiring the old one.
The guided flow produces a 24-word BIP39 seed using the 2048-word dictionary. Follow the device’s rolls and checks. The menu language does not determine the seed dictionary language.
No Cuvex cryptogram is tied to a particular device. You can decrypt it on any compatible Cuvex device, provided you retain the cryptogram and its required credentials. Cryptograms protected with biometrics can only be decrypted on Cuvex BIT.
Cuvex BIT connects directly to Cuvex Desktop over USB-C. To fully operate Cuvex Original with Desktop, you need Cuvex Mirror on a compatible NFC smartphone, linked to your computer over Bluetooth. Mirror reads and writes NFC cards; sensitive operations are reviewed and authorized on your Cuvex device.
