Introduction to Trezor Bridge
Trezor Bridge is software that allows your browser or desktop apps to securely communicate with a Trezor hardware wallet. It acts as a mediator between web3 applications and your hardware device, forwarding transaction requests while ensuring private keys never leave the device. Using Trezor Bridge, you can safely interact with cryptocurrencies, DeFi platforms, NFTs, and other blockchain applications.
Why you need a bridge
Browsers cannot directly access hardware wallets across all platforms.
Bridge provides a standardized local API for communication between apps and Trezor devices.
Ensures transactions are securely signed on the hardware wallet.
Maintains compatibility for desktop and web3 applications.
Installing Trezor Bridge
Download: Visit the official vendor site using a bookmarked or typed URL. Avoid links in emails or search results.
Verify integrity: Check signatures or hashes if provided to ensure the downloaded file is authentic.
Install: Follow OS-specific instructions for Windows, macOS, or Linux. Grant permissions only for device communication and localhost access.
Run the Bridge: Confirm the background service is running before connecting your hardware wallet.
Connecting your Trezor wallet
Plug in your Trezor device via USB or pair with Bluetooth (if supported).
Enter your PIN on-device. Never type it into any software.
Launch a compatible web3 app and select “Connect Hardware Wallet” or similar option.
Approve connection requests and verify addresses and transaction details on-device.
Security tip: Always verify the transaction amount and recipient address on the device screen. Never rely on the app alone.
Using Trezor Bridge with web3 applications
Open a dApp that supports Trezor hardware wallets.
Select your Trezor device when prompted.
Follow on-device confirmations for all transactions.
Disconnect after use to minimize exposure.
Remember that your Trezor device is the final authority — all approvals must be confirmed physically on the device.
Security best practices
Never share your recovery seed or enter it into any software.
Verify official downloads through checksums or signatures.
Keep firmware and Trezor Bridge up-to-date.
Use a dedicated browser for web3 interactions to reduce risks.
Always confirm addresses, amounts, and contract data on-device.
Troubleshooting common issues
Device not detected
Check the USB cable and port.
Ensure Trezor Bridge is running.
Restart the browser or the computer if necessary.
Transaction fails
Check device firmware and app version compatibility.
Verify transaction details on-device.
Ensure internet connection is stable.
Warning: If addresses or amounts on the device differ from the app, cancel immediately. This could indicate malware or a malicious request.
Advanced features
Support for multiple cryptocurrencies and token standards.
Integration with third-party applications and wallets.
Advanced signing for smart contracts and DeFi interactions.
FAQ
Can I install Trezor Bridge on multiple machines?
Yes. You can install it on any trusted machine. Each installation requires connecting your Trezor device for signing operations.
What if I forget my PIN?
Resetting the device is necessary if you forget your PIN. Recover your funds using your recovery seed.
Is the bridge mandatory?
For some platforms, yes. The bridge ensures cross-browser and OS compatibility. Direct connection via WebHID/WebUSB may work for some setups.
