Secure Gateway Bridge for Trezor Web3 Ready

Encrypted local channel

Trezor Bridge sets up an encrypted channel between your device and desktop apps so signing requests are relayed securely and keys stay on the hardware.

Cross-platform support

Available on Windows, macOS and Linux, Trezor Bridge is built to be a cross-platform connector for every Trezor user.

Reliable device detection

The Bridge improves device detection and connection stability so Trezor Suite and dApps talk to your Hardware Wallet® consistently and quickly.

Download & verify

Always download Trezor Bridge from official sources. Look for clear branding ("Trezor Bridge") and secure HTTPS to avoid phishing downloads. Verification prevents tampering and helps keep your hardware wallet secure.

Install & grant permissions

Run the installer for your OS and accept the minimal permissions requested. Bridge runs as a local service that listens for connections from Trezor Suite and authorized apps.

Connect your device

Plug your Hardware Wallet® into USB and open Trezor Suite or a supported Web3 app. The Bridge will automatically forward requests between the app and the device.

Approve on-device

Approve pairing and transactions on your Trezor device screen. Trezor Bridge never exposes private keys — it only moves signed requests between local apps and the hardware device.
