What does a hardware wallet actually do?
A hardware wallet is a device designed to help manage the private keys used to authorize blockchain transactions.
Your assets live on the blockchain
A wallet does not hold coins the way a physical wallet holds cash. It manages the keys that let you authorize actions for blockchain addresses. A hardware device can help keep those keys separate from an everyday computer or phone.
Signing is the important moment
When sending assets or interacting with an application, a wallet signs a transaction. Review the recipient, network, amount, and permissions before approving. The exact review and signing experience depends on the device, software, asset, and application.
Control comes with responsibility
A hardware wallet does not remove phishing, malicious transactions, or backup risks. Learn the recovery process, keep your backup private, and use only verified software. Check a product’s published security information and compatibility before choosing it.
