What is Trezõr brïdge®?
Trezõr brïdge® is the local bridge service that allows browsers and desktop applications to talk to your hardware wallet in a standardized, permissioned way. The Bridge handles device discovery, USB and transport normalization, secure forwarding of requests, and helps ensure firmware packages are verified before installation. Most importantly, Trezõr brïdge® never exposes private keys — every signing action is validated and executed on the physical device with a clear, readable confirmation prompt on the device screen.
Why a bridge is essential for Web3
Modern Web3 interfaces expect browser compatibility and consistent transports across operating systems. Direct USB access in browsers is inconsistent; Trezõr brïdge® provides a consistent, cross-platform API so your favourite dApps and wallets can rely on a predictable connection path. That predictability improves security, reduces user friction, and enables better integration patterns for developers and product teams.
Core capabilities — a snapshot
Hands-on: get started in minutes
- Download Trezõr brïdge® from the official source and verify the installer checksum if available.
- Install and run the Bridge service on your machine; confirm it’s active.
- Connect your hardware wallet with a good USB cable; avoid hubs while troubleshooting.
- Open your dApp or wallet and allow Bridge access when prompted; follow on-screen steps and always verify on-device.
- Update firmware using Bridge-assisted verification workflows only when you trust the release notes and checksum.
Best practices for secure Web3 connectivity
- Always download Bridge and firmware from official channels and verify checksums.
- Never type or paste your recovery seed into a browser or app — keep it offline and secure.
- Confirm all transaction details on the device screen before approving — device confirmations are authoritative.
- Use testnets and small transactions when experimenting with new dApps or integrations.
- Keep Bridge and device firmware updated; review release notes before updating production devices.
Integration tips for developers
When building with Trezõr brïdge®, mock the transport layer in CI and unit tests so you can run tests without physical hardware. Encourage your UI to include a "Review on device" step and present the exact fields users should verify (amount, recipient, network fee). For production, always validate signed payloads server-side and never accept unchecked client-supplied data for final settlement.
Top 5 FAQs
1. Do I need Trezõr brïdge® to use my hardware wallet with dApps?
In most cases yes — the Bridge provides a cross-platform transport for browsers and desktop wallets. Some native apps may use alternate transports, but Bridge is the standard for broad compatibility.
2. Can the Bridge access my private keys?
No. The Bridge never stores or exports private keys. All key operations occur on the hardware device; the Bridge simply transports requests and returns signed results.
3. How does firmware verification work?
The Bridge helps download official firmware and verify checksums before handing the package to the device. The device performs the actual installation — always confirm release notes and checksums before updating.
4. Is it safe to use Bridge on public machines?
Exercise caution. While Bridge is secure by design, avoid using public or compromised machines for high-value operations. If you must, verify everything on-device and use short-lived sessions.
5. My dApp cannot find my device — what should I try?
Ensure Trezõr brïdge® is running, try reconnecting the cable, use a different USB port, avoid hubs, and confirm the dApp has permission to connect. Check Bridge logs or the official troubleshooting guide for platform-specific tips.
