![]() SafePal S1 Hardware Wallet adopts an air-gapped signing mechanism for better security. How does SafePal S1 utilize the Air-gapped signing technology? This type of signing is usually done through QRcode communication, which uses image recognition technology and thus does not rely on any internet or external signal. The Air-gapped signing mechanism is a technology to enable crypto transaction signing without using any radio frequencies or physical connection. What is the air-gapped signing mechanism? ![]() Air-gapped signing mechanism becomes a new option for a hardware wallet to communicate with the external environment without exposing the seed to any online environment. Radio-frequencies and USB connections are often considered not secure enough because they still potentially expose the connection with the hardware wallet to an internet-accessible environment. There are different ways to communicate between the hardware wallet and the software end, such as Bluetooth, NFC, USB connection, QRcode, etc. With the help of external software, a hardware wallet is able to receive an unsigned transaction from the software, sign the transaction, and then transmit the signature to the external software, so that the software can broadcast to the blockchains. Some use desktop applications, some use web clients, and some use mobile Apps. To realize these purposes, a lot of hardware wallets are connected with special external software for crypto management purposes. Furthermore, users also need a user-friendly interface to view the most updated balance and manage crypto assets. In order to execute a transaction, a hardware wallet needs a secure way to interact with the external environment so that it can sign and approve a transaction and transfer the signature to the blockchain. This means that a hardware wallet cannot access the internet, pull data from the blockchain, or automatically update the balance.
