Trezor Bridge: the secure connection that keeps your wallet safe

Trezor Bridge is the official connector that links your physical Trezor device with Trezor Suite and compatible web apps. By installing Trezor Bridge you get a trusted communication channel so your hardware wallet can sign transactions and verify addresses while keeping private keys isolated on the device. Trezor Bridge is essential if you want a secure wallet connection for day-to-day crypto use.

Cross-platform • Maintained • Verified

Secure connection

Trezor Bridge establishes an authenticated, local connection between apps and your hardware wallet. Trezor Bridge ensures that signing requests are relayed safely to the device and that signed responses come back to the requesting app — all while keeping your private keys on the hardware wallet.

Easy install & compatibility

Download the official Trezor Bridge installer for Windows, macOS or Linux. The Bridge installer manages driver and permission tasks, making it simple to connect your wallet to Trezor Suite and web-based wallets that support Trezor Bridge.

On-device verification

Even with Trezor Bridge connecting the app and device, all sensitive actions require you to confirm details on your Trezor device screen. Trezor Bridge never replaces the need for on-device verification — it only enables it securely.

Developer-ready API

Trezor Bridge exposes a stable interface for third-party wallets and services. Developers can integrate with Trezor Bridge so users can connect their hardware wallets to web apps without compromising security.

Whether you use Trezor Suite, a web-based wallet, or a trading platform that supports hardware signing, Trezor Bridge is the official secure connection that ensures your wallet interactions are safe and authenticated.

How Trezor Bridge works — simple architecture, strong security

Trezor Bridge runs a small, local service on your computer that provides an authenticated channel between applications (like Trezor Suite or browser wallets) and your Trezor hardware wallet. When a wallet or app requests to sign a transaction, Trezor Bridge forwards the request to the device. The device then displays the transaction details on its tamper-resistant screen. You verify and approve on-device; the device produces a signed transaction which is returned through Trezor Bridge to the requesting application. This flow guarantees that private keys never leave the hardware wallet and that the final approval always occurs where the keys reside.

Connection model

The connection model is intentionally clear and secure: application ⇄ Trezor Bridge ⇄ Trezor device. Trezor Bridge takes care of local transport, permissions and driver handling, but it does not have access to private keys. The device itself remains the root of trust and the source of signatures.

Security benefits

Using Trezor Bridge preserves hardware wallet security benefits while making interactions with web apps convenient. Because all confirmations happen on-device and the Bridge simply relays requests and responses, the combined model offers a strong guarantee: you physically confirm actions on the device, while Trezor Bridge provides the reliable, official connection required by modern apps.

Features & benefits — why Trezor Bridge matters

Trezor Bridge delivers several benefits for everyday and advanced users. It simplifies device pairing, provides consistent behavior for apps across platforms, handles driver issues on desktops, and offers a documented interface for developers. With Trezor Bridge you get:

  • Official maintenance: updates and compatibility fixes from the Trezor team.
  • Cross-platform support: Windows, macOS, Linux and browser integrations.
  • On-device confirmations: all sensitive approvals occur on the hardware screen.
  • Developer friendliness: APIs and docs for third-party wallet integrations.
  • Simple troubleshooting: clear steps to restart, reinstall or update Bridge when needed.

Daily use tips

Install Trezor Bridge once and leave the service available while you connect your wallet. Restart browsers after installation. When connecting to a new web app, perform a small test transaction. Always confirm the destination address on the Trezor device screen before approving. Keep both Bridge and device firmware updated for the best security posture.

Troubleshooting & best practices

Common issues with Trezor Bridge are usually simple to resolve: try reconnecting the USB cable, use a different port, restart the Bridge service, or reinstall the official Bridge installer. Disable conflicting browser extensions if browser-based wallets cannot see the Bridge. If problems persist, update your device firmware via Trezor Suite and consult official support resources. Always ensure you downloaded Trezor Bridge from the official site to avoid tampered installers.

Backup reminder

Trezor Bridge is a communication layer — not a backup. Your recovery seed is the only reliable backup of your wallet. Secure your recovery seed offline (paper, metal plate, safe deposit box) and never input it into a computer or online form. Trezor Bridge simply enables secure communications; it does not store or manage your seeds.
