The Essential Link Between Your Trezor Device and the Digital World
Trezor Bridge is a lightweight, secure communication layer developed by SatoshiLabs that enables your Trezor hardware wallet to interact seamlessly with web applications, desktop software, and cryptocurrency platforms. Without Trezor Bridge, your device cannot communicate with online services — making it a critical component of the Trezor ecosystem.
Trezor Bridge acts as a secure messenger between your physical Trezor hardware wallet (Model T or Model One) and supported web interfaces like Trezor Suite Web, MyEtherWallet, MetaMask (via WalletConnect), and other dApps. Unlike traditional software wallets that expose private keys to the internet, Trezor Bridge ensures that sensitive cryptographic operations are performed exclusively on the hardware device — never on your computer or browser.
Introduced in 2018 as a replacement for the older Trezor Chrome extension, Trezor Bridge runs as a background process on your operating system (Windows, macOS, Linux) and facilitates encrypted communication through local sockets. This design eliminates browser-specific vulnerabilities and improves compatibility across different platforms and applications.
Installing Trezor Bridge is straightforward and takes less than 2 minutes:
Pro Tip: Always download Trezor Bridge from trezor.io or suite.trezor.io. Third-party sources may distribute malware disguised as legitimate software.
The most common use case for Trezor Bridge is with Trezor Suite — the official desktop and web application for managing your crypto portfolio. When you connect your Trezor device:
Beyond Trezor Suite, Trezor Bridge powers connectivity with dozens of popular platforms:
If your Trezor device isn’t detected, try these steps:
| Issue | Solution |
|---|---|
| “Bridge not running” error | Restart Trezor Bridge from system tray (Windows) or menu bar (macOS) |
| Device not recognized | Try a different USB cable/port. Use original Trezor cable. |
| Firewall blocking connection | Allow trezord.exe or trezord in Windows Defender/macOS firewall |
| Outdated version | Download latest Trezor Bridge from trezor.io |
SatoshiLabs continues to improve Trezor Bridge with each release. Recent updates include:
The long-term vision includes native WebUSB integration to eventually reduce reliance on background processes, though Trezor Bridge will remain essential for maximum compatibility and security on desktop environments.
Trezor Bridge is more than just software — it's the trusted gateway that keeps your cryptocurrency safe while enabling full interaction with the blockchain world. By handling communication locally and keeping private keys isolated on your hardware device, Trezor Bridge represents a gold standard in cryptocurrency security architecture.
Whether you're a Bitcoin HODLer, an Ethereum DeFi enthusiast, or an NFT collector, Trezor Bridge ensures your assets remain under your control — always.
Download Trezor Bridge today from trezor.io and experience hardware-grade security for all your digital assets.
Beyond basic connectivity, Trezor Bridge supports advanced cryptographic functions such as:
For developers building dApps, Trezor Bridge exposes a JSON API over local HTTP (port 21325). Example connection:
{
"service": "trezord",
"path": "/trezord",
"version": "2.0.31"
}
Full API documentation is available at github.com/trezor/trezord-go.
While both enable hardware wallet connectivity, Trezor Bridge offers superior third-party integration and open-source transparency. Ledger requires proprietary apps, whereas Trezor Bridge works with any compatible web interface.
