Secure, simple, and smart connectivity between your Trézór hardware wallet and the web environment.
Trézór Bŕidge® is the official communication software developed by SatoshiLabs to link your Trézór™ hardware wallet with browser-based applications such as Trézór Suite. It creates a safe channel that lets your computer and your wallet “talk” to each other while keeping your private keys completely offline.
When you plug a Trézór wallet into your computer, your browser can’t access the USB device directly because of security restrictions. Trézór Bŕidge solves this by running as a small background service that mediates encrypted messages between your browser and the wallet.
Within Trézór Suite, the Bridge enables key features like wallet initialization, firmware updates, and transaction signing. It ensures that every instruction coming from the browser is verified and properly authorized on the hardware device itself.
The Bridge will launch automatically and remain running in the background, allowing smooth interaction with Trézór Suite or compatible third-party wallets.
The entire architecture of Trézór Bŕidge is built on the principle of isolation of secrets. Even though the Bridge handles data exchange, it never gains access to private keys or seed phrases. All sensitive operations (such as signing transactions) are performed inside the hardware wallet itself.
The Bridge is digitally signed by SatoshiLabs, so your operating system can verify its authenticity. Never install versions from unverified sources or emails pretending to offer updates.
The Bridge works with major browsers including Chrome, Firefox, Edge, and Brave. While newer browsers also support WebUSB for direct USB communication, Trézór Bŕidge remains the most reliable option for universal compatibility and long-term support.
WebUSB connections can break after browser updates or OS policy changes, but Bridge runs independently from the browser, ensuring consistent performance for critical operations.
Make sure the Bridge service is running. On Windows, look for “Trezor Bridge” in the system tray; on macOS or Linux, check active processes. If it’s not running, relaunch the application or reinstall it.
Use a different USB cable — some charging-only cables lack data transfer wires. Also try a different port or restart your computer after installing the Bridge.
Always keep Trézór Bridge, Trézór Suite, and firmware up to date. Outdated components can cause connection errors or missing features.
Ensure your browser allows local connections and pop-ups for suite.trezor.io. Clearing the cache or restarting the Bridge service often resolves temporary communication issues.
Trézór Bŕidge is not limited to Trézór Suite alone. Many third-party crypto applications use the same communication layer to enable secure signing and account management. Examples include MetaMask (via Trézór connect API), Electrum, and Exodus.
The Bridge provides a universal interface for these applications to request public keys or sign transactions without ever exposing private data. This flexibility is one of the key reasons for its widespread adoption in the crypto ecosystem.
The Bridge does not collect or transmit personal information to SatoshiLabs. All operations occur locally on your computer. Only anonymous usage statistics may be sent (if you opt-in within Trézór Suite) to help developers improve user experience.
SatoshiLabs continues to evolve Trézór Bŕidge to support new blockchains, operating systems, and web security standards. Upcoming versions are expected to include improved performance and a self-diagnostics dashboard for easier troubleshooting.
With increasing regulatory focus on digital assets and privacy, having a reliable bridge between hardware and software wallets will remain crucial for both individual and institutional users.
Trézór Bŕidge® is the essential link that connects your secure hardware wallet to the dynamic crypto web. It ensures that every interaction with Trézór Suite or third-party apps is authenticated, encrypted, and trustworthy.
Installing and maintaining the Bridge takes only minutes but significantly enhances your security posture. For anyone serious about safeguarding digital assets, Trézór Bŕidge remains an indispensable part of the crypto toolkit.
