Trezor Bridge - Secure Connection Between Wallet & Browser

Trezor Bridge is the lightweight local software that has historically acted as the secure messenger between your Trezor hardware wallet and web browsers or the Trezor Suite desktop app. It runs on your computer, establishes an encrypted local channel to your device, and ensures websites and apps can talk to your Trezor without exposing private keys or signing operations to the internet.

Security first

Trezor’s security model means private keys never leave the device and every transaction must be confirmed on the physical Trezor. Bridge itself limits exposure by creating a local-only encrypted connection and verifying device authenticity before passing requests along — so even if a computer is compromised, an attacker still needs physical access and your PIN/passphrase to move funds. For these reasons on-device confirmation, PIN protection, passphrase support, and secure firmware updates are core defenses.

Benefits at a glance

  • Seamless browser integration: Bridge makes web wallets and dApps detect your Trezor reliably across Chrome, Firefox and Edge without manual driver fiddling.
  • Local-first communications: No sensitive keys or signing operations are sent over the internet — Bridge facilitates local, encrypted handshakes only.
  • Plug-and-play: Once installed, Bridge runs in the background and automatically connects your device when plugged in, simplifying daily use.

Advanced usage tips

  • Use Trezor Suite + Trezor Connect: Trezor Suite’s recent updates introduced a Trezor Connect popup for interacting with third-party wallets directly from the Suite/web apps — useful for combining convenience with hardware-level security. Multisig transaction hashes can now be reviewed on-device for greater auditability.
  • Passphrase & view-only wallets: Enable a passphrase for plausible deniability or create view-only wallets for monitoring addresses without exposing signing capabilities. Recent Suite improvements let you manage passphrase visibility more easily.
  • Keep firmware & Suite updated: Always update device firmware and Suite/Bridge installers from the official site to get the latest security and compatibility fixes. The changelog shows frequent firmware releases that improve features and safety.

New features & lifecycle notes

Trezor Suite has been evolving rapidly: recent updates add third-party integration popups, improved multisig support, and device authenticity checks. At the same time, there is an official deprecation notice for the standalone Trezor Bridge — users are encouraged to move to the current Trezor Suite workflows to avoid compatibility issues with future releases. If you still have standalone Bridge installed, follow the official guidance to uninstall and migrate.

Quick install & safety checklist

  1. Download Bridge/Suite only from the official Trezor site.
  2. Verify checksums where provided and keep firmware updated.
  3. Use PIN + optional passphrase, and confirm every transaction on the device screen.

Trezor Bridge (and the broader Suite ecosystem) is designed to combine the convenience of browser-based wallets with the hard security guarantees of a hardware wallet. Migrate to the supported Suite path, keep things updated, and use on-device confirmations and passphrases for the strongest protection.
