A simple, secure bridge between your hardware wallet and the apps you trust. Trezor Bridge, also written as Trezor/Bridge or trezor bridge, powers private-key-safe interactions for desktops and browsers.
Trezor Bridge is lightweight middleware that securely connects your Trezor hardware wallet to desktop and browser-based cryptocurrency applications. Where browser support for USB and device access can be inconsistent, Trezor/Bridge provides a stable, cross-platform connection layer. When you plug in your Trezor device, trezor bridge manages device discovery, encrypted communication, and request routing so apps can sign transactions and read public account information without exposing private keys.
Users demand secure, reliable transaction signing. Trezor Bridge isolates the hardware wallet from browser quirks and OS updates, reducing failed connections and confusing prompts. Trezor/Bridge keeps the cryptographic operations on your device and handles only permitted messages, so even when an app needs a signature the signing remains in the trusted device. By using trezor bridge, developers and hobbyists get consistent behavior across Windows, macOS, and Linux without custom USB drivers or browser plugins.
Under the hood, Trezor Bridge runs locally and exposes a secure, authenticated HTTP endpoint only accessible from the local machine. Applications detect and talk to the running Trezor/Bridge service to forward commands to your hardware wallet; the device handles PIN, passphrase, and user confirmation flows. The result: applications receive signed transactions or public keys after you physically confirm actions on the device, and trezor bridge never stores sensitive secrets or transmits them off your computer.
Installing Trezor Bridge is typically a one-click or package manager operation depending on your OS. Once installed, Trezor/Bridge usually launches automatically when you plug in the Trezor device. Keep trezor bridge up to date: updates can include bug fixes, new coin support, and security improvements. If an app can’t find your hardware wallet, verifying that Trezor Bridge is running is the most common troubleshooting step.
Security is core to Trezor Bridge design. The service only facilitates local communication and enforces origin checks so that unauthorized websites cannot command your device. Interactions require physical approval on the Trezor device, protecting private keys from remote compromise. Even when Trezor/Bridge is running, your seed phrase and PIN never leave the hardware wallet. That means trezor bridge enhances usability without trading away the fundamental hardware-based security model.
Developers building wallet integrations appreciate that Trezor Bridge abstracts OS-specific device access details. Standardized JSON-RPC style messaging and clear documentation let apps detect devices, enumerate accounts, and request signatures. Using Trezor/Bridge lets devs focus on UX and transaction flow rather than low-level USB handling. If you’re building tools that interact with hardware wallets, integrating with trezor bridge reduces maintenance overhead and user friction.
