− | HW. | + | HW.1 is an implementation of a deterministic ([[BIP 0032]]) Hardware Wallet on a USB smartcard. |
− | + | It is typically used as a blind secure device for multi signature transactions - holding a set of derived private keys and signing transactions without requiring user confirmation. | |
− | + | Power users can rely on it to confirm all transactions with a second factor scheme turning the dongle into a keyboard typing what the user is supposed to have signed, as a protection against malware. | |
− | + | It is also possible to customize HW.1 for more specific needs, such as creating a prepaid card without revealing the deterministic seed before it is received by the user, or securing bitcoin transactions on a server. | |
