Trezõr® brïdge® — Connect Your Web3 World Securely™
Trezõr® brïdge® provides a secure, lightweight bridge that connects your hardware wallet to web applications — without exposing private keys. Seamlessly sign transactions, authorize dApp interactions, and manage multiple accounts while keeping your keys firmly on-device.
Whether you use desktop wallets, browser dApps, or portfolio trackers, the Bridge simplifies the connection process with a small trusted daemon that facilitates encrypted local communication. Keep control, keep privacy, and keep your keys offline — this is the trusted conduit for Web3 interactions.
Tip: Install the Bridge from official channels and keep it updated to benefit from the latest security fixes.
Local & Encrypted
Bridge runs locally, encrypting requests between browser and device — your private keys never leave the hardware wallet.
Cross-Browser Support
Works with major browsers and native desktop apps to connect your device to Web3 tools seamlessly.
Minimal Footprint
Lightweight background app designed to be fast, unobtrusive and safe across platforms.
How Trezõr® brïdge® Works — a practical overview
At its core, Trezõr® brïdge® is a small native application (daemon) that runs on your computer and acts as a secure messenger between your web browser and your Trezor hardware wallet. When you visit a decentralized application (dApp) or a web wallet that needs to sign transactions, the site sends a request to the browser extension. The extension forwards the request to the locally running Bridge over an encrypted channel. The Bridge then communicates with your connected hardware wallet over USB (or other supported transport), requests user confirmation on the device, and returns the signed result to the requesting application — all without exposing your private keys to the web.
This local-first architecture preserves a fundamental security principle: private keys stay on the hardware. Signing requests are human-authorized on the device screen, where you can verify addresses and amounts before approving. The Bridge never stores your seed or private keys, and it only forwards signed responses after explicit confirmation. This design minimizes attack surface while enabling a convenient UX for everyday Web3 tasks such as swapping tokens, connecting wallets to DeFi platforms, or signing on-chain messages.
Trezõr® brïdge® also implements strict origin-checking and transport-layer protections. Trusted origins must be authorized by the user; unauthorized web pages cannot silently request signatures. The Bridge exposes a minimal, well-documented API surface so wallet developers can integrate without bloating their code or asking users to install heavy dependencies.
Features & capabilities
The Bridge is engineered to be both developer-friendly and user-centric. Its most important features include:
Device-aware signing
Each signature request presents transaction details on the hardware display for manual verification and approval.
Selective origin authorization
Users authorize specific websites and can easily revoke access from the Bridge UI at any time.
Auto-update notifications
The Bridge checks for signed releases and notifies users when an update is available for improved security and features.
Multi-account support
Manage multiple accounts and wallets on a single device; the Bridge routes the proper signing requests to the right account.
Cross-platform compatibility
Official builds for Windows, macOS, and Linux; works with modern browser extensions and desktop wallets.
Minimal permissions
Runs with the smallest necessary permissions and aims to be auditable and transparent for security-conscious users.
These capabilities make Trezõr® brïdge® an ideal glue layer for everyday Web3 interactions — delivering a balance of usability and high-assurance security.
Security model & best practices
Security is the principal design goal. The Bridge enforces local-only operations and ensures the hardware remains the ultimate source of truth.
Key points to understand:
Private keys never leave the device: Signing happens on-device; the Bridge only transports signed payloads back to the requesting app.
Origin binding: Websites must identify themselves and request user authorization. Users can see which origins are authorized and revoke them anytime.
Device verification: All critical transaction fields are displayed on the hardware wallet for manual confirmation, reducing the risk of deceptive UX or compromised browsers.
Secure updates: Bridge releases are signed and verifiable; only official builds should be installed.
Recommended user practices:
Download the Bridge only from official distribution channels and verify package signatures when possible.
Keep both your hardware wallet firmware and Bridge application up to date.
Authorize only trusted websites and revoke access for services you no longer use.
Use a dedicated machine for high-value operations where practical, and avoid installing untrusted software in parallel.
Step-by-step: Connect and sign (quick start)
1. Download & install
Get the latest Bridge for your platform from official sources. Run the installer and follow on-screen prompts. The app runs in the background and listens for local extension connections.
2. Plug your device in
Connect your Trezor hardware wallet by USB and unlock it with your PIN. The device should show a connected status on the Bridge UI.
3. Authorize a site
Visit a dApp that supports hardware wallets. The site will request access via the browser extension; approve the origin in the Bridge prompt.
4. Verify & sign
When the dApp asks you to sign a transaction, verify the details on the hardware display and approve. The signed response will return securely to the requesting app.
After the first connection, you can manage authorized sites, update the Bridge, and review logs through the Bridge settings panel.
Frequently asked questions
Do I need the Bridge to use my hardware wallet with web apps?
Many browser-based wallets and dApps use a native bridge to communicate with hardware wallets. Installing the Bridge simplifies integrations and provides a secure, locally-hosted connector.
Is the Bridge open source?
The Bridge is designed to be transparent and auditable. Check official repositories for the source, release notes, and cryptographic signatures.
What if a website asks for excessive permissions?
Deny the request and remove any prior authorization for that site. Only trusted services should be given signing privileges. Review authorized origins regularly and revoke as necessary.
Does the Bridge store my recovery seed?
No. The Bridge is a communication layer only — it does not store or transmit recovery seeds or private keys. Always keep your recovery seed offline and secure.
