Connect Your Web3 World Securely™

Welcome to Trezõr® brïdge®—the official secure channel that connects your Trezor hardware wallet to Web3 apps, your browser, and more. Encrypted, open-source, and battle-tested, Trezor Bridge keeps your keys safe while enabling smooth transactions across platforms.

Why Trezor Bridge Matters

• Encrypted Communication: Bridge ensures all data between your device and browser stays encrypted and secure — private keys remain on-device at all times :contentReference[oaicite:1]{index=1}.
• Universal Compatibility: Works smoothly across major browsers and operating systems — Windows, macOS, Linux, Chrome, Firefox, Edge, Brave :contentReference[oaicite:2]{index=2}.
• No Plug-ins Needed: Eliminates deprecated browser extensions. Everything runs at system level for simplicity and reliability :contentReference[oaicite:3]{index=3}.
• Always Up-to-Date: System-level installer ensures you're always using the latest secure version — no manual patching needed :contentReference[oaicite:4]{index=4}.

How Trezor Bridge Works

Here’s the simplified flow to understand its architecture and security model:

1. Bridge installs as a native background service, typically accessible via 127.0.0.1:21325 or through system tray :contentReference[oaicite:5]{index=5}.
2. When you connect your Trezor device via USB, Trezor Bridge detects and facilitates exclusive communication with browser-based apps :contentReference[oaicite:6]{index=6}.
3. Actions like signing transactions are securely encrypted and physically confirmed on the hardware — private keys never touch your computer :contentReference[oaicite:7]{index=7}.
4. Authorization and confirmation always occur on the Trezor device, leaving no room for remote tampering or key exposure.

Installation & Troubleshooting

Install Steps

• Download Trezor Bridge from trezor.io/start to ensure authenticity :contentReference[oaicite:8]{index=8}.
• Run the installer (Windows/macOS/Linux) and follow prompts.
• Upon launch, connect your device — browsers like Chrome & Edge may bypass needing Bridge thanks to WebUSB support :contentReference[oaicite:9]{index=9}.

Common Issues & Solutions

• If Bridge says “not running,” check for the background process (e.g. trezord) or reinstall via official source :contentReference[oaicite:10]{index=10}.
• Browser issues? Try disabling extensions or using a different browser (Edge often works when Chrome doesn't) :contentReference[oaicite:11]{index=11}.
• Still stuck? Restart your computer, reinstall Bridge, or verify browser permissions for USB access :contentReference[oaicite:12]{index=12}.

Security & Best Practices

• Trust Only the Official Installer: Always download Trezor Bridge from trusted sources — avoid phishing or mimic sites :contentReference[oaicite:13]{index=13}.
• Private Keys Remain Secure: Even if Bridge is compromised, your keys are sealed within your device — all critical actions must be confirmed physically :contentReference[oaicite:14]{index=14}.
• Verify Device Prompts: Never confirm a transaction unless you review its details on the device screen.
• Use Desktop App When Possible: Trezor Suite desktop app bypasses the need for Bridge and offers a streamlined, secure experience :contentReference[oaicite:15]{index=15}.
