What Is Trezor Bridge?

Trezor Bridge is the official desktop middleware developed by SatoshiLabs to serve as a secure channel between your Trezor hardware wallet (e.g., Model One, Model T, Safe 3/5) and web browsers or desktop applications like Trezor Suite, MyEtherWallet, MetaMask, and Electrum. It handles USB communication, encryption, and protocol translation—ensuring seamless and safe interaction without relying on legacy browser extensions Google Sites+6trezooroio009+6site-bridge.dora.run+6.

How Trezor Bridge Works

• REST & WebSocket proxy: It facilitates JSON-RPC API calls between browser or desktop app and the device.
• Access control: Only whitelisted applications may connect to it, reducing the risk of unauthorized access.
• Encryption layer: All USB data is encrypted and integrity-checked, preventing tampering or man-in-the-middle exploits.
• Auto-update engine: Verifies signatures and downloads new versions automatically help-bridge-trezor.gorgias.help.

Security & Privacy Considerations

• Cryptographic integrity: Signed and verified against PGP keys managed by SatoshiLabs, ensuring authenticity.
• Open-source code: The Bridge is open-source, allowing community and professional audits for backdoors or vulnerabilities.
• Redundancy with Fallbacks: In case of Bridge issues, Trezor Suite uses WebUSB or WebHID as temporary alternatives.
• Deprecation strategy: Transitioning the Bridge logic into Suite means tighter integration, fewer attack surfaces site-bridge.dora.run+12Trezor+12Trezor+12.
