Trust the hardware screen
The Trezor device’s screen is your final authority. Even when using Bridge, never accept a transaction until you verify it on the device. The screen prevents man-in-the-middle alterations and shows details the browser may not display. This step is central to hardware wallet security.
Avoid untrusted websites
Only connect your device to reputable web wallets or verified applications. Attackers attempt to mimic wallet UIs or create malicious dApps that request dangerous approvals. If a website asks you to sign unexpected data, disconnect and investigate before continuing.
Limit approvals and signed messages
Some dApps ask for broad contract approvals that permit spending tokens without further confirmations. Prefer one-time approvals and revoke unused permissions. Regularly inspect your wallet’s approved contracts and remove those you don’t recognize or no longer use.
Use a dedicated machine when possible
For high-value operations, consider using a clean, dedicated computer environment. Minimizing software and extensions reduces the attack surface. If you must use a general-purpose machine, keep the OS and browser up to date and run reputable security software.
Local network awareness
Bridge operates locally, but it still relies on the operating system’s USB stack and browser permissions. Do not expose your device to public or untrusted networks during setup. Avoid using Bridge in heavily restricted corporate networks where interception or filtering may alter traffic unexpectedly.
By centering every signing decision around the device screen, avoiding unknown websites, and managing approvals carefully, you maximize the security benefits of Trezor Bridge while maintaining web convenience.
