A hardware wallet can isolate signing keys from a general-purpose computer, but it cannot determine the user's intent. Many losses happen because a valid device signs a malicious or misunderstood transaction.
Blind signing and unreadable contract data reduce this protection. Avoid approving interactions you cannot interpret or independently verify.
Plan for physical damage, loss and inheritance without placing all copies in one location.
A hardware wallet is one layer. Secure browsing, careful transaction review and a recovery plan are still required.
The screen is the security boundary
Verify the destination, amount, network and contract interaction on the hardware device itself.

Recovery remains a human responsibility
The recovery phrase can recreate the wallet without the original device. Anyone who obtains it can control the funds. Keep it offline, test the recovery process safely and never enter it into a website, support form or unsolicited application.Plan for physical damage, loss and inheritance without placing all copies in one location.
Supply chain and setup matter
Obtain devices through a trusted channel, initialize them yourself and verify firmware through official tools. Treat unexpected preconfigured phrases or requests to "synchronize" a wallet as hostile.A hardware wallet is one layer.
