In today’s rapidly evolving digital landscape, protecting your cryptocurrency assets is not a choice — it’s a necessity. Trezor™ Bridge plays a crucial role in this process by serving as the communication layer between your Trezor hardware wallet and your computer. Whether you're sending Bitcoin or managing Ethereum tokens, Bridge ensures a secure, private link between your browser and device.
Trezor Bridge is a background service that enables communication between your Trezor hardware wallet and supported web interfaces, such as Trezor Suite Web and third-party apps like MetaMask (when configured correctly).
It replaces the now-deprecated Chrome extension, offering a more secure, cross-browser, cross-platform communication channel.
