Software wallet vs hardware wallet

The difference isn’t only what they look like. One of the most important differences is where transaction signing happens.

With a software wallet, the keys live on the device running the wallet.
That makes access convenient — but the same device is also exposed to apps, websites and other software.

A hardware wallet creates separation. The interface can live on your phone while the private key remains on dedicated hardware.

With United Network, that dedicated hardware is the card.
You review the transaction on your phone and tap the card to authorize it.
The signing happens on-chip. Your phone handles the interface.
Your card handles the key.

That separation is the point of hardware security.
