Overview

Trézór Suite is the official desktop and web companion application for Trézór hardware wallets. It combines a modern interface with hardware-backed key management so you can manage multiple accounts, view portfolio balances, sign transactions securely, and interact with supported decentralized applications — all while your private keys remain protected in your Trézór device. This guide explains the full lifecycle: from installation and initial setup to everyday workflows, advanced features, security best practices, and troubleshooting.

Why Trézór Suite?

The Suite acts as an orchestration layer: it builds transactions, fetches public blockchain data, and displays account information — but crucially, the secret signing operation happens inside your Trézór hardware. That separation reduces risk: even if your computer is compromised, attackers cannot extract private keys. Trézór Suite provides a polished UX that lowers barriers for newcomers while offering power-user controls for advanced custody and enterprise use.

Before you begin

Prepare a secure environment before you install: use a trusted desktop machine, have a reliable USB cable, and pick a private place for the initial setup. Keep a physical medium for recording your recovery seed (paper, dedicated seed card, or a metal backup). Avoid public networks for critical setup steps and firmware updates.

Installation (Desktop & Web)

Desktop installation

Download the Trézór Suite installer for your OS (Windows, macOS, Linux) and verify integrity where possible.
Run the installer and follow platform prompts to grant necessary permissions.
Launch Trézór Suite and create a local profile. Profiles store UI settings but not private keys.

Web usage

The web version provides similar functionality via a browser interface. When using the web app, ensure you are on the official domain and that your browser is up-to-date. The Trézór device will still require physical confirmation for any signing action.

Initial device setup

Connect your Trézór hardware wallet to the computer using a data-capable cable.
Follow the Suite prompts to initialize a new device or restore from an existing recovery seed.
Choose and confirm a strong device PIN — this prevents casual physical access.
Write down the recovery seed exactly as shown on the device; store copies offline in separate secure locations.

Do not save your recovery seed digitally, photograph it, or enter it on websites. Your seed is the only true backup of your accounts.

Adding accounts & managing assets

After initialization, use Trézór Suite to add accounts for the blockchains you hold. The Suite supports popular networks and many tokens. Add an account, then receive a small test deposit to confirm your addresses match on both the Suite and your device screen.

For Bitcoin: use coin control features where available to manage UTXOs.
For Ethereum and EVM chains: Trézór Suite shows token balances and contract interactions.
For new tokens: add them via the Suite’s supported token interface if available.

Transaction workflow

Trézór Suite constructs unsigned transactions and sends them to your Trézór device for signing. Always verify the displayed recipient, amount, and fee on your hardware screen before approving. This is the final and authoritative confirmation step.

Create the transaction inside the Suite.
Review the transaction details in the Suite.
Confirm the same details on the Trézór device screen.
Device signs the transaction securely and Suite broadcasts it to the network.

Security best practices

Security is layered — device protections, software integrity, and user practices matter equally. Follow these guidelines:

Only install the Suite from official sources and verify checksums where possible.
Never disclose your recovery seed or PIN; the Suite or support will never ask for them.
Verify transaction details on the hardware device, not just the Suite UI.
Keep firmware and Suite software up-to-date via official update channels.
Use a secure environment (trusted machine and network) for high-value operations.
Consider metal backups for recovery seeds to withstand fire and water damage.

Advanced features

Passphrase-protected hidden wallets

Optional passphrases act as an additional secret (a 25th word) that derives hidden wallets. They provide plausible deniability and stronger privacy, but they also introduce operational complexity — losing a passphrase is equivalent to losing access to that wallet.

Multisignature & enterprise workflows

Trézór devices can be used in multisig setups where transactions require multiple independent signatures. For organizational custody, adopt role separation (preparer, approver, signer) and document procedures for firmware updates, co-signer rotation, and emergency recovery drills.

Integrations & dApp connections

The Suite supports secure integrations with selected decentralized applications. When connecting third-party apps, review requested permissions carefully and ensure you only approve expected actions on the device. Prefer read-only or limited-scope connections when possible.

Privacy considerations

While keys are secure, network-level metadata (IP addresses, timing) can affect privacy. If privacy is critical, use privacy-preserving practices: segregate machines, use VPNs or onion routing, avoid address reuse, and consider running or using trusted nodes.

Backup & recovery

The recovery seed is the single point of truth for restoring funds. Create multiple offline copies and distribute them across geographically separate secure locations if appropriate. Periodically perform a recovery drill on a spare device to validate procedures.

Troubleshooting common issues

Many problems are environmental. If the Suite cannot detect your device: try a different USB cable, confirm the device is unlocked, restart the Suite, and reboot your machine. Firmware update failures often result from interrupted connections — retry on a stable machine. If you suspect a compromised environment, stop and move to a trusted machine.

When to seek support

Contact official support if you encounter tampering signs, unexpected device prompts, or firmware anomalies. Never share your recovery seed with support. For critical incidents, follow documented incident response procedures and, if part of an organization, escalate internally per your custody policy.

Practical checklist before sending large transactions

Confirm the device firmware is updated and genuine.
Verify Suite version and check for recent advisories.
Test small transfers first to confirm recipient addresses.
Ensure network connectivity and that no proxy or VPN is interfering (unless intended for privacy).
Double-check recipient addresses on the hardware device screen.

Trézór Suite empowers secure crypto management by combining a modern user interface with hardware-backed cryptographic guarantees. Adopt layered defenses, maintain disciplined operational practices, and treat your recovery material with the utmost care — these habits will protect your assets today and years into the future.
