Introduction — what this guide covers

This guide explains how Trézór Bŕidge® acts as the secure gateway between your desktop (browser or Trézór™ Suite*) and your hardware wallet. You'll learn how to safely install Bridge, initialize your device, manage crypto accounts inside the Suite, apply firmware updates, and handle common problems without compromising your keys or recovery seed.

Key concepts (brief)

  • Trézór Bŕidge® — a small background app that enables a secure local connection between your machine and the hardware wallet.
  • Trézór™ Suite* — the desktop app/web interface for managing wallets, accounts, and firmware.
  • Recovery seed — 12- or 24-word phrase that restores your wallet; never store it digitally.
  • PIN & passphrase — local device access controls; PIN protects the device UI, passphrase creates hidden wallets.

Before you begin — security checklist

Follow these steps before installing Bridge or initializing your Trézór device:

  • Use a trusted machine (avoid public or shared computers).
  • Ensure OS and browser are updated to recent, stable versions.
  • Download software only from official, verified sources (bookmark the official site).
  • Prepare an offline medium to record your recovery seed (metal or paper backup).
  • Temporarily disable unneeded remote access and screen sharing to avoid leaks during setup.

Installing Trézór Bŕidge® (step-by-step)

Windows

  1. Download the Windows installer from the official Trézór page.
  2. Run the installer and grant administrative permissions when prompted.
  3. Allow any driver installs; after installation Bridge will run as a background service.

macOS

  1. Download the macOS .dmg and open it.
  2. Drag the Bridge app to Applications and run it. macOS may request that you approve it under System Preferences → Security & Privacy.
  3. Grant any permissions required for USB access.

Linux

Linux users can install via official packages, snaps, or through their distribution's package manager. Ensure udev rules are installed and applied so non-root users can access USB devices. Example commands are available in the Suite or the official docs.

Security tip: verify checksums or signatures when available and never run untrusted binaries. If in doubt, re-download from the official vendor site.

First connection and initializing in Trézór™ Suite*

  1. Connect your hardware wallet to the computer using a quality data cable; the device should show a welcome screen.
  2. Open Trézór™ Suite* — it will detect Bridge and prompt you to connect the device.
  3. Choose to create a new wallet or recover an existing seed. For new wallets, the Suite will walk you through generating a recovery seed, writing it down, and setting a PIN.
  4. After initialization, add accounts for the cryptocurrencies you want to manage (BTC, ETH, ERC-20 tokens, etc.).

Creating and protecting your recovery seed

Your recovery seed is the ultimate backup. Best practices:

  • Write the words legibly on the supplied recovery card or a durable medium.
  • Create multiple physical backups and store them in geographically separated secure locations (bank safe deposit, home safe, trusted custodian).
  • Consider a steel backup device for fire/water resistance.
  • Never photograph or upload your seed. Do not type it into any online form or save it digitally.

Using crypto in Trézór™ Suite*

Trézór™ Suite* provides a wallet interface to view balances, manage accounts, and send/receive transactions. Key points:

  • Transactions must be approved on the hardware wallet screen. This is the canonical confirmation step — always verify amounts and destination addresses on the device display.
  • Keep your Suite app up to date — updates may include UX improvements and security patches.
  • Test your workflow with a small transaction first to confirm you understand the send/receive flow.

Firmware updates — proceed with care

Firmware updates are critical for security. When prompted to update:

  • Confirm the prompt appears on the device screen and proceed only through the official Suite or verified installer.
  • Do not interrupt power during an update.
  • If an update fails or the device shows a recovery screen, follow the official recovery procedure — do not enter your seed into untrusted tools.

Advanced security options

PIN policies

Choose a PIN that is memorable but not guessable. The PIN is entered on the device itself to reduce exposure to host keyloggers.

Passphrase (optional)

Using a passphrase creates a hidden wallet derived from your seed + passphrase. This adds plausible deniability and a second factor but also increases the risk of irretrievable loss if you forget the passphrase. Document your passphrase practice securely (e.g., mnemonic pattern) if you choose to use it.

Multisig and enterprise setups

For large holdings consider multisig solutions (multiple hardware wallets across different locations) and formal custodian or legal arrangements. Multisig reduces single-point failure risk but is more complex to manage.

Troubleshooting Bridge & Suite connectivity

If your device isn’t detected, follow these steps in order — test after each:

  1. Confirm Trézór Bŕidge® is running (system tray / Activity Monitor / service list).
  2. Try a different USB cable and a different port — prefer a direct motherboard port over hubs.
  3. Restart your browser and the Suite app. Reboot the computer if necessary.
  4. Disable browser extensions that may block local requests (privacy/network extensions).
  5. Reinstall Bridge from the official package and reapply udev rules on Linux.
  6. Inspect OS device manager for driver issues on Windows.

Common error: "Device not recognized"

Often due to bad cables, incompatible USB ports, missing drivers, or Bridge not running. Replace the cable, switch ports, restart Bridge, and reinstall if necessary.

Common error: "Firmware recovery required"

This appears when a firmware update was interrupted or corrupted. Use the official recovery steps. If unsure, contact official support and avoid entering your recovery seed into unknown software.

Backup & recovery strategies

Plan for loss scenarios proactively:

  1. Record the recovery seed at device setup and verify legibility.
  2. Store at least two secure copies in separate locations.
  3. For highest security, pursue multisig or geographically distributed custody.
  4. Test your backups periodically by restoring to a secondary device (use a test wallet / small amounts first).

Operational security checklist

  • Never disclose your recovery seed or PIN to anyone — official support will never ask for them.
  • Verify software and downloads via official channels only.
  • Use the device screen to confirm transactions — the device display is the source of truth.
  • Keep your OS and applications patched to reduce malware risk.
  • Consider a dedicated machine for large-value management or air-gapped workflows when feasible.

Developer notes & integrations

Developers integrating with Trézór devices should use official libraries and keep credentials and private keys off host machines. Use Bridge as the local connector during development, and test integrations in staging environments with small amounts before production rollout.

Glossary

Suite
Desktop or web application for account management, firmware, and transactions.
Recovery seed
Word list that restores wallet state on compatible devices.
Passphrase
Optional secret adding an additional derivation layer to seeds to create hidden wallets.

Checklist before you finish

  • Trézór Bŕidge® installed and running
  • Device initialized and PIN set
  • Recovery seed recorded securely in primary and secondary locations
  • Firmware updated to the latest official release
  • Small test transaction performed and verified on the device

When to contact official support

Contact official Trézór support if you encounter hardware tampering concerns, unrecoverable firmware errors after following official recovery steps, or unexpected prompts for your seed outside of the Suite. Official support will never request your seed or full passphrase.

Final notes & recommended next steps

Using Trézór Bŕidge® together with Trézór™ Suite* gives you a secure, practical desktop workflow for managing crypto. Prioritize seed safety, apply firmware updates promptly through official channels, and run small test transactions after setup. For significant holdings, consider multisig and diverse custody strategies. Above all—treat the recovery seed as your last line of defense.
