Privacy-first connection
Bridge runs locally on your machine. It never transmits private keys or transaction secrets to external servers — it only forwards secure commands between your browser and device.
Trezor Bridge
Secure connection for your crypto wallet
Connect your Trezor hardware wallet safely — every time.
Trezor Bridge is a lightweight, open-source connector that creates a secure, private channel between your Trezor device and browser-based wallets and apps. Fast installs, minimal permissions, maximum control.
End-to-end security
Encrypted local transport — your private keys never leave the device.
Instant pairing
Connect once and use any compatible app without repeated setup.
Automatic updates
Quiet, secure updates keep compatibility and security current.
Open & auditable
Public source code, independently auditable for transparency.
Why Trezor Bridge?
Compatibility with major wallets
Works seamlessly with popular wallet applications and browser-based services that support Trezor’s standard APIs.
Verified & signed releases
Installations are code-signed and checksummed so you can verify authenticity before running — a small step that prevents compromise.
How it works — in three steps
1
Install Bridge
Download and run the installer for your OS. Bridge runs as a lightweight background service.
2
Connect your Trezor
Plug in your device and unlock it. Bridge pairs the browser and hardware over a local, encrypted channel.
3
Approve actions on-device
All sensitive operations (signing, key export) require manual confirmation on the Trezor device itself.
Security highlights
- Local-only transport — no cloud key storage.
- Code-signed installers and release checksums.
- Minimal permissions: only communicates with browsers and Trezor devices.
- Open-source codebase for community review.
FAQ
Is Bridge required to use my Trezor?
For most browser-based wallet integrations on desktop, Bridge is required to provide a secure, standard interface. Mobile and certain apps may use alternative connection methods.
Can Bridge access my private keys?
No. Private keys never leave the hardware. Bridge only relays encrypted commands; signing happens on your device.
How do I verify the installer?
Every release includes a cryptographic checksum and a digital signature. Follow the documentation steps to verify signatures before installation.
Does Bridge run on startup?
By default it may run as a background service to enable instant device detection. You can change startup behavior during installation or in settings.
