What is Hardware Wallet?

A hardware wallet is a non-custodial wallet and is considered a secure way to personally store crypto. Typically looking like a USB stick, a hardware wallet is usually offline but connects via USB or bluetooth to an online device when making transactions. Although technically connected to the internet at times, it's still considered a cold — or offline — wallet as transactions are signed "in-device." This means the transaction has been signed offline prior to being broadcast to the blockchain via the internet. Due to this security feature, malware is unable to sign these transactions — or view your keys.
