What is Trezor Bridge?
Trezor Bridge is the lightweight, trusted connector that enables your computer and browser to communicate securely with your Trezor hardware wallet. Acting as a secure gateway, this USB bridge mediates all interactions between Web3 apps and your hardware device, ensuring that private keys remain offline while giving you fast, reliable access to account data, transaction signing, and wallet management.
Why a secure gateway matters
In the era of Web3, connectivity should never come at the cost of control. Trezor Bridge preserves user sovereignty by isolating cryptographic operations on your hardware wallet. When an application requests a signature, the request travels through the USB bridge and arrives at your device where it is presented for on-device confirmation. This architecture prevents secret key exposure and reduces attack surface for software-level threats.
Key advantages of Trezor Bridge
- Hardware wallet protection: The USB bridge ensures your private keys never leave the hardware wallet during use.
- Cross-platform compatibility: Works smoothly on Windows, macOS, and Linux; auto-updates optionally for security.
- Fast and stable: Low-latency communication for real-time transaction previews and quick signing.
- WebUSB & native fallback: Supports modern WebUSB-enabled browsers and falls back to secure native protocols when needed.
- Privacy-first: Minimal telemetry, clear permissions, and transparent data handling policies.
How it works — simply and securely
Installation is straightforward: the Trezor Bridge installer creates a secure local connection so your browser can talk to your hardware wallet without requiring full system-level drivers. When a dApp or the Trezor Suite requests access, Trezor Bridge asks for explicit user consent and opens a short-lived channel. All signing operations are confirmed physically on the Trezor device — that is the secure gateway principle in action.
Designed for users and developers
For end users, Trezor Bridge delivers a seamless setup experience and dependable connectivity for day-to-day self-custody operations. For developers, it offers stable APIs, clear documentation, and consistent behavior across environments — enabling secure Web3 integrations without exposing sensitive material.
Pro tip: Always download Trezor Bridge from your official domain. Verify checksums and signatures to ensure authenticity. The secure gateway model only works if the software is genuine.
