Trezor Bridge® — Connect Your Trezor to Web Browsers

Trezor Bridge is the official local helper software developed by SatoshiLabs that securely connects your Trezor hardware wallet to web browsers and desktop applications. It acts as a trusted transport layer that allows browser-based apps, such as Trezor Suite Web and compatible web wallets, to communicate with your device while ensuring that private keys and signing operations remain safely on the hardware. Installing Bridge enables a smooth, reliable workflow for everyday tasks — checking balances, signing transactions, and managing accounts — without exposing secret material to the browser environment.

Why use Trezor Bridge?

Modern web browsers restrict direct access to USB devices for security reasons. Bridge solves this problem by creating a secure local channel that web applications can use to discover and interact with your Trezor device. This design minimizes the attack surface: the browser simply requests operations, while the Trezor device enforces user confirmation for any sensitive action, such as approving a transaction or revealing an address. The result is convenience plus strong hardware-backed security where every critical cryptographic operation is performed on-device.

Getting started

Getting started is straightforward. Visit the official start page at trezor.io/start to download the correct Bridge installer for your operating system. Bridge is available for Windows, macOS, and Linux. After installation, restart your browser and open the Trezor-compatible web app, for example Trezor Suite Web at suite.trezor.io. When a connection is requested, Bridge will prompt to authorize the web page; always verify the page’s URL and only approve connections from trusted sites. If you prefer a desktop client, Trezor Suite Desktop bundles device communication and may simplify your workflow.

Security considerations

Security is central to Trezor Bridge’s role. The Bridge process runs locally and does not transmit your recovery seed or private keys to the internet. Critical cryptographic operations happen inside the hardware device, and each operation requires a physical confirmation on your Trezor. SatoshiLabs publishes official Bridge installers and recommends downloading only from trezor.io to avoid tampered or fake binaries. Additionally, regular firmware and software updates include integrity checks and improvements to keep the entire stack secure.

Features & capabilities

Features and capabilities include automatic device discovery, support for multiple Trezor models, encrypted local communication, and integration with popular web wallets and third-party tools that follow Trezor’s API. For developers, Trezor Bridge exposes a stable interface for building integrations while maintaining user consent flows. For everyday users, Bridge enables core actions such as viewing account balances, exporting public addresses for receiving funds, and approving transactions — all with the guarantee that sensitive operations are confirmed on the device screen.

Troubleshooting

Troubleshooting common issues is usually simple. If your browser does not detect the device, make sure Bridge is running and your cable is connected properly. Try reconnecting the Trezor, restarting Bridge, or rebooting your browser. On some systems, browser extensions or strict security settings may interfere; temporarily disabling such extensions or checking firewall settings can help. If problems persist, consult the official support resources at trezor.io/support where step-by-step guides and community-driven assistance are available.

Best practices

Best practices when using Trezor Bridge include only downloading Bridge from the official site, verifying URLs and digital signatures when available, keeping firmware and Bridge updated, and never sharing your recovery seed with anyone. Use the desktop Trezor Suite if you prefer an app that bundles device communication, or use the web suite with Bridge when you need browser-based access. Always verify transaction details on your Trezor screen before confirming — never rely solely on the host application’s display or browser warnings.

Role in the Trezor ecosystem

Trezor Bridge is an enabling piece of the broader Trezor ecosystem. By delivering a secure, local communication channel, Bridge helps users enjoy the convenience of modern web-based wallet interfaces while maintaining the strong security guarantees of hardware wallets. Whether you are a developer integrating Trezor support or a user managing assets, Bridge plays a small but critical role in preserving security without sacrificing usability. For official downloads and detailed installation instructions, visit the Trezor start page at trezor.io/start. To open Trezor Suite Web, navigate to suite.trezor.io. For troubleshooting and support resources, consult trezor.io/support. Always rely on official channels and documentation when installing or updating Bridge, and treat your recovery phrase as the ultimate backup for your wallet. Keep your devices updated and follow official guidance to maintain strong security and long-term access. Today.
