Trezor Bridge – Official Communication Tool
Trezor Bridge is the software that allows your Trezor hardware wallet to communicate securely with your computer and browser. Without it, your device cannot connect properly to Trezor Suite or supported wallet interfaces. Trezor Bridge works in the background, enabling safe data exchange between your hardware wallet and the app you use for managing your crypto.
What Trezor Bridge Does
Trezor Bridge acts as a secure communication layer. It:
connects your Trezor device to your computer
enables access to Trezor Suite and supported browsers
allows safe transaction signing on your hardware wallet
ensures no private keys leave the device
It does not store your funds or your recovery seed. It simply enables the connection required to manage your wallet.

How It Keeps Communication Secure
Security is handled in several ways:
data is encrypted during communication
transactions must be physically confirmed on your Trezor
private keys remain inside the hardware wallet
Bridge does not access your recovery seed or PIN
Even if your computer is compromised, the hardware wallet still verifies what you approve on the device screen.
Trezor Bridge vs Browser Extensions
Previously, Trezor used browser plugins. Trezor Bridge improves on this by:
offering better stability
supporting more browsers
reducing compatibility problems
avoiding reliance on browser extension stores
Most users now rely on Bridge together with Trezor Suite.
