Trezör® Bridge® — Connect Your Web3 World Securely™

Trezör® Bridge® is a lightweight, trusted connector that enables hardware wallets to interact with modern Web3 applications — safely, predictably, and with clear user consent. It acts as the secure bridge between your physical wallet and the decentralized services you rely on, whether you are checking balances, signing contracts, or confirming a multi-step transaction.

At its heart, Bridge focuses on one thing: giving users explicit control over how their private keys are used. Unlike cloud-based key storage or browser-subsidized cryptography, hardware wallets keep keys offline. Bridge ensures those keys are never exposed to the web by mediating every request and making confirmations visible and tangible to the user.

This page explains how Bridge works, why it matters, and how to get started immediately.

Why a bridge is essential for secure Web3

Web3 apps are diverse and dynamic: decentralized exchanges, NFT marketplaces, decentralized identity providers, and on-chain games all need a reliable way to request signatures from users. A hardware wallet without a trusted connector would require awkward manual steps — copying signatures, pasting payloads, or trusting unvetted browser extensions. Trezör® Bridge® simplifies that flow with a single, audited component that translates web requests into device-secured prompts.

• Seamless: Bridge removes friction while preserving security guarantees.
• Transparent: Every request is shown on device and in the desktop UI before signing.
• Audited: Built with clear code and a small trusted surface to minimize risk.

How Bridge protects your keys (in plain language)

When a Web3 site asks to sign a transaction, Bridge receives the request but never accesses your private key. The signing operation happens inside the hardware wallet itself. Bridge performs three essential roles:

1. Discovery and device management — it finds connected Trezör devices and shows human-readable names.
2. Request translation — it maps a web application's raw request to the wallet's signing format.
3. User consent UI and verification — it displays the transaction summary so you can confirm what you are signing.

That last piece — explicit user verification — is critical. Bridge forces a simple contract: the device signs only what you approve. No hidden fields, no background approvals, no surprises.

Getting started — a quick checklist

To start using Bridge with your hardware wallet and favorite Web3 apps, follow this short checklist. Each step is designed to minimize risk while getting you up and running quickly.

Best practices for safe usage

Bridge is a security tool, and like all security tools, its benefits depend on how you use it. Adopt these habits to maximize safety:

• Keep Bridge and your device firmware up to date — updates close security gaps and add protections.
• Only approve requests you initiated — if you see an unexpected prompt, cancel and investigate.
• Use official sources — download Bridge only from the official site or links you trust.
• Be cautious on public networks — when using shared computers, prefer a trusted environment.

What to expect when a site requests a signature

When a Web3 app asks for a signature through Bridge, here's the simple sequence you'll observe:

1. The site requests connection and transaction information.
2. Bridge opens a local connection and asks you to choose a device and account.
3. The hardware wallet displays the transaction details for review.
4. After explicit confirmation on your device, the wallet signs the payload and Bridge relays the signature to the web app.

This flow ensures that even if a web page is malicious, it cannot sign transactions without a physical confirmation. Bridge acts as the local gatekeeper.

Advanced features

For power users and integrators, Bridge offers additional capabilities:

• Developer-friendly APIs for local testing and secure integration.
• Support for multiple device types and accounts, enabling teams and power traders to manage several wallets simultaneously.
• Detailed logs to help audit activity locally — logs are stored on your machine and are not transmitted externally.

Privacy considerations

Bridge is built with privacy in mind. It only relays the specific requests you approve and does not collect or transmit your private keys, seed phrases, or sensitive account metadata. Transactions themselves are public by design once broadcast to the chain, but Bridge limits what metadata leaves your device and computer.

Troubleshooting — common questions

Device not detected? Try a different cable, confirm Bridge is running, and ensure your system recognizes USB devices. On some systems a driver or permission adjustment may be required.

App can't connect? Make sure the web application is using a supported API and that you authorized the connection in Bridge. Refresh the page and re-initiate the connection if necessary.

Worried about malicious pages? Cancel any suspicious prompts. If you think your machine may be compromised, move your device to a clean environment and verify using known-good systems.

How to install (concise)

Installation is straightforward: download the official Bridge installer for your operating system from the trusted source, run the installer, and follow on-screen instructions. After installation, start Bridge (it usually runs as a background helper), plug in your hardware wallet, and open a supporting Web3 app.

For step-by-step guidance and official documentation, the recommended starting point is trezor.io/start, where clear links and verified downloads are published. Always prefer official sources to third-party downloads to reduce exposure to tampered packages.

Why trust Bridge?

Trust is earned through transparency, small attack surface, and repeatable security practices. Bridge is intentionally minimal: it doesn't hold keys, it exposes a limited API surface, and it is designed to produce reproducible, auditable behavior. Combined with device-side confirmations, this makes a strong defense-in-depth for Web3 interactions.

Use cases — who benefits most?

Bridge is useful for:

• Everyday users who want to interact with Web3 marketplaces or DeFi safely.
• Developers building dApps who need a predictable local signing interface during development and testing.
• Teams and institutions that use hardware wallets for treasury management and need reliable desktop integration.

Wrapping up — a secure connection to your Web3 life

Trezör® Bridge® is an intentionally simple, highly secure helper that allows hardware wallets to do what they do best: keep private keys offline while enabling real-time, trusted interactions with web services. When used together with hardware verification and sensible operational practices, Bridge reduces attack surfaces and gives users clear control over every signature they produce.
