The Secure Connection Between Your Trezor Hardware Wallet and Computer
Trezor Bridge is an essential background software developed by SatoshiLabs that enables seamless and secure communication between your Trezor hardware wallet (Model T or Model One) and web applications such as Trezor Suite, MetaMask, MyEtherWallet, and many other supported dApps.
Trezor Bridge acts as a communication facilitator (a “bridge”) that allows your browser to securely talk to your Trezor device even when websites normally cannot access USB or connected devices due to browser security restrictions.
It runs silently in the background as a local server (usually on port 21325) and translates commands from web pages into instructions that your Trezor device can understand and respond to — all while keeping your private keys safely inside the hardware wallet, never exposing them to the internet or your computer.
Installation is straightforward and takes less than 2 minutes:

Yes — 100% safe when downloaded from the official source. Trezor Bridge never has access to your seed phrase or private keys. All sensitive operations are performed exclusively inside your Trezor device. The software is open-source and regularly audited.
Even in 2025, Trezor Bridge remains a lightweight, reliable, and critical piece of software for anyone who wants maximum flexibility with their Trezor hardware wallet. Whether you’re connecting to DeFi platforms, signing transactions with MetaMask, or simply prefer the web interface, keeping the latest version of Trezor Bridge installed ensures the smoothest and most secure experience possible.
