The secure communication channel between your Trezor device and browser
Trezor Bridge is a background service that allows your web browser to communicate securely with your Trezor hardware wallet. It replaces older browser plugins and provides a more reliable, private, and direct connection between your device and supported applications such as Trezor Suite.
Instead of relying on browser extensions that may have compatibility issues, Trezor Bridge runs locally on your computer. This ensures stable performance, automatic device recognition, and improved security when confirming transactions or accessing wallet data.
Trezor Bridge operates as a lightweight background program. When a supported website requests access to your device, the bridge acts as a secure translator between the browser and the hardware wallet.
The system does not automatically expose your device. Each sensitive action — such as signing a transaction — still requires confirmation on the Trezor screen, ensuring user control at all times.
Works across modern browsers without needing special plugins or extensions.
Reduces connection drops and improves communication reliability during transactions.
Prevents direct browser access to sensitive device operations without verification.
Recognizes connected Trezor devices instantly once installed.
Installing Trezor Bridge is straightforward. Users download the correct version for their operating system and run the installer. Once installed, the service starts automatically when needed.
No advanced configuration is required. After setup, compatible platforms like Trezor Suite will detect the device seamlessly when connected via USB.
Trezor Bridge does not store private keys, seed phrases, or wallet data. Its sole purpose is communication. All cryptographic signing remains inside the hardware wallet, which keeps sensitive operations isolated from the computer and internet threats.
This design ensures that even if a system is compromised, attackers cannot move funds without physical access to the device and user approval.
Trezor Bridge is typically required when using web-based wallet interfaces. Desktop applications like Trezor Suite may integrate communication directly, but browser environments rely on Bridge for proper device access.
