🔑 If you’ve been using a Trezor hardware wallet for a few years, you’ve likely encountered Trezor Bridge — the background software that once enabled your browser to “talk” securely to your Trezor Model One or Model T. In this up-to-date guide, we’ll explain exactly what Trezor Bridge was, why it was needed, and what has replaced it in 2025.
Trezor Bridge (also known as trezord) was a lightweight daemon/application developed by SatoshiLabs that facilitated encrypted communication between a Trezor hardware wallet and web-based applications. It ran silently in the background and allowed browsers (especially those without native WebUSB support, like Firefox) or third-party wallets to detect and interact with your connected Trezor device.
Introduced in 2018 as a replacement for the old Chrome extension, Trezor Bridge solved a major problem: browsers increasingly restricted direct USB access for security reasons. The Bridge acted as a trusted local proxy, ensuring private keys never left the hardware wallet while still enabling seamless signing of transactions.
Before modern WebUSB became widespread:
Without Trezor Bridge, users would see errors like “device not found” or “Bridge not running” when trying to access suite.trezor.io/web or legacy wallet.trezor.io.
As of recent Trezor Suite updates, the standalone Trezor Bridge is officially deprecated and should be uninstalled. SatoshiLabs now bundles the required communication layer (called nodeBridge or an embedded bridge) directly inside the Trezor Suite desktop application.
Key advantages of the new approach:
If you still have the old standalone Bridge installed, it can actually interfere with the latest Trezor Suite versions. Official recommendation: uninstall it completely and rely on Trezor Suite.
1. Download the official Trezor Suite desktop app from trezor.io/trezor-suite (recommended for maximum privacy and features).
2. For quick browser access, use Trezor Suite Web with Chrome/Edge (WebUSB) or run the desktop app in the background.
3. Always verify downloads using the official PGP signatures provided on the Trezor website.
Using the desktop Suite eliminates the need for any separate Bridge while giving you native support for more coins, firmware updates, and advanced features like CoinJoin privacy tools.
Absolutely. Trezor devices remain one of the most audited and trusted hardware wallets on the market. Private keys never leave the device, all communication is encrypted, and the open-source codebase allows independent security researchers to verify its integrity. By moving away from the standalone Bridge, SatoshiLabs has actually streamlined and hardened the connection process.
Remember: Your cryptocurrency is only as secure as your seed phrase backup. Store it offline, never digitally, and consider enabling a passphrase for an extra hidden wallet.
No. The standalone version is deprecated. Use the latest Trezor Suite desktop app, which includes the required connectivity layer automatically.
This usually occurs if an old standalone Bridge is still installed and conflicting. Uninstall the old Bridge via the official guide and restart Trezor Suite.
Yes — in Chrome or Edge (with WebUSB). For Firefox or maximum reliability, simply run the Trezor Suite desktop app in the background; it provides the necessary bridge functionality.
No. SatoshiLabs recommends removing it to avoid conflicts with newer Suite versions. Follow the uninstall instructions here: trezor.io/learn/a/deprecation-and-removal-of-standalone-trezor-bridge
Yes. Most modern integrations now use WebUSB or the embedded bridge from Trezor Suite. Keep Suite running or use a compatible browser.
Always download directly from trezor.io or suite.trezor.io. Verify file signatures when possible.
