What Is Trezor Bridge?

Trezor Bridge is a lightweight background application that enables secure communication between your Trezor hardware wallet (e.g. Model T, One) and web browsers. Acting as a local host service, it allows browser-based tools such as Trezor Suite and third‑party apps like MetaMask, MyEtherWallet, and other DeFi platforms to detect and interact with your hardware wallet—even when WebUSB support is absent Google Sites+1Google Sites+1Trezor+11help-bridge-docs-en.dora.run+11Google Sites+11. It replaces older Chrome extensions with a stable, cross‑platform connector supporting Windows, macOS, and Linux help-bridge-docs-en.dora.runtrezor-bridge-cloud-app.newzenler.com.

Coinbase Sign‑In Integration Using Trezor Bridge

For users migrating assets from platforms like Coinbase, Trezor Bridge plays a key role in the sign‑in and transfer experience:

1. Initiating the Transfer: In Trezor Suite, choose the account to receive funds. Confirm the wallet‑generated receive address on the Trezor device.
2. Coinbase Send Process: Log into Coinbase, select Send & Receive, choose your cryptocurrency, paste the verified Trezor address, and initiate the transfer Trezor+1Trezor+1.
3. Hardware Authentication via Trezor Bridge: When a third‑party app or wallet prompts you to sign transactions or log in, Trezor Bridge ensures your hardware signature steps occur securely—you unlock your device with your PIN and approve actions directly on the device screen. This flow relies on Trezor Connect, which is facilitated by Bridge Trezor+11Trezor+11trezor-bridge-cloud-app.newzenler.com+11.
