Trezor Bridge — The secure gateway to your hardware wallet
Trezor Bridge connects your browser and your Trezor hardware device with a private, reliable and verified channel. Use Trezor Bridge to manage cryptocurrencies, sign transactions and keep private keys offline. Designed for speed, privacy and seamless integration.
Private & local
Trezor Bridge establishes a local gateway so your private keys never leave your device. The bridge is a local, secure service running on your system.
Verified connection
Every session between your browser and your Trezor is cryptographically verified. Trezor Bridge enforces endpoint authenticity and tamper-free communication.
Cross-platform
Available for Windows, macOS, and Linux. Trezor Bridge is lightweight, auto-updating and integrates with major wallets and browser apps.
How Trezor Bridge works
Install local bridge
Install Trezor Bridge on your computer. The installer creates a small local service that listens only on your machine and never exposes remote ports.
Connect device
Plug in your Trezor hardware wallet. Trezor Bridge detects the device and pairs it to authorised browser sessions through a secure handshake.
Sign securely
Use your favourite web wallet to create transactions. The bridge forwards requests locally, your Trezor displays details and requires physical confirmation to sign.
Security and privacy
Trezor Bridge is intentionally minimal: it acts purely as a local gateway. It never uploads your seed, your private keys, or transaction signing material to the cloud. All cryptographic signing happens on the device. The bridge supports robust update verification and signed firmware to defend against tampered software.
