The trusted link between your Trezor hardware wallet and browser — protecting your digital assets.
Trezor Bridge® is a lightweight communication tool created by Trezor (by SatoshiLabs) to connect your Trezor hardware wallet with supported desktop browsers and applications. It serves as a secure channel allowing your wallet to interact with web interfaces such as Trezor Suite.
Trezor Bridge® replaces older browser extensions, providing a simpler, more reliable, and more secure experience. It operates in the background and establishes a direct connection between your physical wallet device and web-based crypto tools.
With the rapid growth of decentralized finance (DeFi) and Web3 wallets, security remains a top concern. The year 2025 has seen an increase in phishing websites and compromised browser extensions. By using Trezor Bridge®, you bypass these risks entirely.
Setting up the Bridge is easy and takes less than five minutes:
Trezor Bridge® offers far more than a simple communication channel — it’s an essential security layer that strengthens how your hardware wallet interacts with the online world.
The Bridge supports modern browsers such as Chrome, Edge, Brave, and Firefox. Unlike outdated extensions, it operates independently of browser APIs, ensuring reliability across updates.
Once installed, Bridge automatically detects your connected Trezor device. This discovery process uses encrypted local communication to ensure no data leaks or device impersonation.
The Trezor development team regularly updates Bridge to patch vulnerabilities and improve compatibility with the latest operating systems and browsers.
You don’t have to open or manage the Bridge manually. It runs quietly in the background, maintaining an active, secure connection to Trezor Suite whenever needed.
When you plug your Trezor wallet into your computer, the Bridge detects the hardware device
via USB and creates a secure local connection to your browser. Your browser communicates with
the Bridge through a local HTTP server (e.g., localhost:21325), which only accepts
verified requests from trusted origins.
Every transaction you initiate on Trezor Suite is sent securely through this channel, prompting confirmation on your physical Trezor device. The private key never leaves your wallet, making it virtually impossible for hackers to intercept.
If you encounter problems while connecting your device, try these steps:
Trezor Bridge® adheres to the latest encryption and data security protocols. It doesn’t collect or transmit any personal information. All interactions occur locally between your computer and the hardware device.
In 2025, Trezor introduced enhanced compatibility for macOS Sonoma and Windows 11, along with native support for Trezor Safe 3. The latest version of Bridge also integrates tighter sandboxing to prevent local port hijacking attacks.
Future updates aim to include:
If you ever need to remove or reinstall Trezor Bridge®:
The process will not affect your wallet data or stored cryptocurrencies — all assets remain safely within your Trezor hardware device.
Trezor Bridge® is more than a simple software utility; it’s the digital handshake that ensures your hardware wallet and online tools communicate securely. Whether you’re managing Bitcoin, Ethereum, or hundreds of supported tokens, Bridge guarantees that all operations remain encrypted, verified, and trustworthy.
In 2025, with increasing cyber threats, having a dependable and transparent communication layer like Trezor Bridge® is essential for any serious crypto user.
