Welcome to this guide on Trezõr® brïdge®, your secure link between web interfaces and your Trezõr® hardware wallet. This page introduces how it works, how to install it safely, how to use it, and best practices to keep your crypto assets secure.
Trezõr® brïdge® is a lightweight software tool that enables encrypted communication between your Trezõr® hardware wallet and supported browser-based wallet interfaces (e.g. Suite Web or third‑party dApps). It acts as a trusted intermediary, allowing commands (e.g. “sign transaction”, “get address”) to pass securely—while ensuring your private keys remain on the hardware device and never exposed to your computer’s browser environment.
Think of brïdge® as a secure translator that sits locally on your machine. It mediates all interaction but doesn’t hold or process sensitive key material itself.
Modern web browsers enforce strict security and sandboxing, which often blocks direct USB access or hardware device communication. brïdge® bridges that gap by offering a local service (running on localhost) which the browser can securely talk to.
Some reasons brïdge® is still relevant:
brïdge® operates entirely on your local machine. It listens on a local port (e.g. 127.0.0.1) and does not send data over the internet. Web wallet interfaces talk to brïdge®, and brïdge® talks to your hardware device via USB (or other supported channel). This ensures that very little (if any) of your data leaves your system except encrypted payloads meant for the hardware wallet.
When a web wallet requests an action—say, “get public key” or “sign this transaction”—that request travels via brïdge® to the hardware. The wallet interface can display information (amounts, recipient addresses), but the actual confirmation and signing happen on the Trezõr® device screen. brïdge® ensures the request is properly formatted, but it never has the ability to forge or alter the core cryptographic operations.
For any operation that could change state—especially signing a transaction—your Trezõr® device will show a prompt with details (amount, fee, target address). You must approve manually on the hardware device for the action to execute. This ensures that even if your computer is compromised, no transaction can go through without your physical consent.
Follow these steps to install brïdge® securely:
trezor.io/start or the verified download page.Once your device is plugged in and brïdge® is active, supported web wallets should display a "Connect Hardware Wallet" option. When selected, a handshake sequence occurs: the wallet asks brïdge® to identify the device, then proceeds to request public addresses, transaction history, or other queries.
After connection, the wallet can query account balances, transaction history, token holdings, and more. These are read-only operations, generally safe and non‑destructive. brïdge® relays those read requests to the device and returns the responses for display.
When you initiate a “Send” operation, the wallet packages a transaction message and sends it via brïdge® to your Trezõr® device. The hardware displays the transaction details (recipient, amount, fee) and requests your confirmation. Only after your approval is a cryptographic signature generated, and the signed transaction returned via brïdge® to the wallet for broadcast to the blockchain network.
Beyond basic sends/receives, brïdge® supports more advanced operations depending on wallet/dApp compatibility:
Here’s a checklist if your device isn’t recognized or fails to connect:

Trezõr® is evolving its software architecture. In newer versions, the desktop/mobile Trezõr® Suite often integrates connectivity features directly, reducing or eliminating the need for a separate brïdge® service. Users migrating to updated software should uninstall legacy brïdge® installs to avoid conflicts.
Nonetheless, understanding the role of brïdge® remains important for working with web interfaces, older browsers, or legacy setups. As browser APIs mature, future equivalents may shift toward WebUSB / WebHID, local secure APIs, or browser-embedded modules—but the principles of secure hardware-mediated signing will endure.
Trezõr® brïdge® is the critical secure link that allows your hardware wallet to communicate safely with browser-based wallets and decentralized apps. It lives locally, mediates encrypted requests, and ensures that your private keys never leave the device. Every transaction or sensitive action demands your physical confirmation on the device itself.
While desktop or mobile Suite apps may reduce reliance on brïdge® in the future, for web-based workflows it remains indispensable in many environments. Use the installation and usage practices laid out above, adopt strong security habits, and always double-check what’s happening on your device before you approve anything.
With proper setup and vigilance, you can confidently “Connect Your Crypto Securely™” using Trezõr® brïdge®.
