1. What is Trezor Bridge?
Trezor Bridge is an official communication tool provided by Trezor, enabling your hardware wallet to interact with browsers and compatible cryptocurrency apps. If you have ever attempted to manage your coins through a browser extension or an online interface, you’ve likely seen prompts directing you to Trezor.io/start or asking you to download trezor bridge.
Before the introduction of trezor bridge, devices relied on Chrome apps or browser-specific APIs. However, modern browsers like Chrome, Brave, Firefox, and Edge no longer support these legacy systems. Trezor Bridge solves this problem by acting as a secure, universal connection layer.
