Hardware wallets are used to store crypto assets as a safer alternative to always connected wallets.
The hardware wallet is non-custodial and acts as a two-factor identification tool. Only software connects to the Internet, but not the wallet itself. The signature is generated offline and transmitted to a device connected to the network, on which the required application is already open.
The user is then prompted to confirm the transaction. The signature is generated from the key and transmitted to a device connected to the blockchain. It is impossible to recover the private key from the signature and your funds are protected from interception. So which devices are included in the top hardware wallets?
