Trezor Bridge — Connect Your Web3 World Securely™ 🔐✨

A tiny, trusted bridge that lets your Trezor hardware wallet talk to web apps safely. Use it to sign transactions, manage accounts, and get peace of mind in a noisy web3 world. 🛡️🌐

Why Trezor Bridge? 🤔

Trezor Bridge is designed with clarity and security at its core. It keeps critical keys isolated on your device while providing a clear, auditable channel for browser apps to request signatures and account data. Perfect for developers, power users, and anyone who values self-custody. 🔒

Key features ✨

  • 🔐 Hardware-isolated signing — Private keys never leave your Trezor.
  • 🌍 Cross-platform — macOS, Windows, Linux support.
  • ⚡ Fast & minimal — Lightweight bridge process with minimal overhead.
  • 🧭 Developer-friendly — Clear JSON-RPC endpoints and example flows.
  • 🔍 Transparent prompts — Human-readable screens on-device for every transaction.
  • ♻️ Auto-updates (optional) — Stay current with secure updates.

Install & connect 🚀

Follow these steps to get started. The commands below are illustrative — use official installers for your OS.

1. Download the Trezor Bridge installer from the official site.
2. Run the installer and follow prompts.
3. Plug in your Trezor device and open a compatible web wallet or dApp.
4. Approve the connection on your device screen.

Developer quick example 💻

A very small pseudo-example showing how a dApp requests accounts (illustrative only):

// request accounts (pseudo-code)
const accounts = await trezorBridge.request({ method: 'eth_requestAccounts' });
console.log('accounts', accounts);

Tip: Always verify the transaction details on the Trezor device screen before approving. The device shows amounts, recipient addresses, and gas — that’s your last line of defense. ✅

Privacy & best practices 🕵️‍♀️

Trezor Bridge is a local service that runs on your computer. It does not collect your keys, seeds, or transaction data for analytics. Keep your OS and browser up to date, use strong device passwords, and consider hardware-backed security for extremely high-value holdings. 🛡️

Frequently asked questions ❓

Do I need Trezor Bridge to use my Trezor with web wallets?

Yes. Bridge creates a secure local channel between your browser and the hardware wallet. Some browsers may support direct HID/U2F connections, but Bridge offers the most reliable cross-platform experience.

Is Bridge safe?

Bridge itself is a small local program. The security model relies on your Trezor device showing transaction details and requiring physical confirmation. Never approve transactions you do not expect.
