Trezor Suite®
Official Desktop & Web Crypto App™ — Getting Started

Overview — Why Trezor Suite Matters

Trezor Suite is the official desktop and web app that works with your Trezor hardware wallet to provide a secure, full-featured crypto management experience. With Trezor Suite, your private keys never leave the device: the Suite builds transactions, the device displays human-readable transaction details, and the user approves signatures on the hardware. This separation of duties reduces major attack surfaces and helps ensure funds remain under the user’s control.

Whether you are setting up Trezor Suite for the first time, adding multiple accounts, or integrating a plugin for custom workflows, the Suite is designed to make secure operations clear and repeatable. The rest of this page covers step-by-step setup, plugin guidance, security architecture, advanced user workflows, privacy considerations, troubleshooting, and a final checklist to keep your account safe.

Preparing to Use Trezor Suite

Before beginning, gather your Trezor device, the provided USB cable, a trusted computer (or the desktop Suite installer), and paper for recording your recovery seed. Trezor Suite provides a guided experience, but your physical seed and PIN are critical to long-term access—write the recovery seed down by hand, store it offline, and treat it as the ultimate backup.

If your security needs are advanced (organization custody, high-value holdings), consider separating duty: one person handles device operations, another manages seed custody, and auditors use watch-only accounts. Trezor Suite supports watch-only modes to enable secure auditing without exposing signing keys.

Install & Set Up Trezor Suite

Installing and initializing Trezor Suite is straightforward. Choose the desktop client for a self-contained experience or the web client for easy access. Both provide the same on-device security model. The steps below will get you up and running with Trezor Suite.

  1. Install Suite: Run the Suite installer for your OS or open the web client on a trusted browser. The Suite is the control center for device initialization and account management.
  2. Verify Device: On first connection Trezor Suite will instruct you to verify that your device is authentic. Do not skip this verification — Trezor Suite can perform attestation checks that help confirm the device is genuine.
  3. Create PIN: Choose a secure PIN to protect physical access to the device. The PIN is required each time you connect your Trezor to Suite.
  4. Generate Recovery Seed: Your Trezor will generate a 12- or 24-word recovery seed. Write these words down in order and store them offline. Confirm a selection of words when Suite prompts you.
  5. Add Accounts: In Trezor Suite add accounts for the blockchains you want to use. Install per-coin modules on the device where required — Suite will manage this process.

After these steps, Trezor Suite is ready to sign transactions on your behalf while keeping keys secure on the device. Proceed to the plugin section if you plan to extend Suite with custom modules or connectors.

Plugin & Connector Integration for Trezor Suite

Trezor Suite is plugin-ready: organizations and advanced users can add local plugins or connectors that extend functionality — for example, internal accounting integrations, custom market data feeds, or enterprise signing policies. Plugins should be designed to respect the Suite security model: they may prepare or analyze transactions but must not attempt to access private keys or bypass on-device approval.

Common plugin use-cases

How to safely add a plugin

  1. Develop the plugin to run as a local, sandboxed process and avoid elevated privileges unless necessary.
  2. Ensure the plugin communicates with Trezor Suite over well-defined, documented local APIs and uses authenticated IPC channels where possible.
  3. Keep the plugin code auditable and sign the installer so users can verify authenticity.
  4. Never implement functionality that requests or stores the recovery seed or private keys — all signing must happen on the hardware device via Suite’s transport layer.

Below is a small plugin skeleton (example) showing how a local plugin could post messages to the Suite UI. This is illustrative only — adapt securely for production.

// Example (pseudo) plugin: local connector
// - listens for a Suite websocket or IPC endpoint
// - supplies market data or policy decisions
// - never handles private keys or seeds

const net = require('net');
const socket = net.connect({ path: '/tmp/trezor-suite-plugin.sock' });

socket.on('connect', () => {
  socket.write(JSON.stringify({ type: 'plugin.register', name: 'acct-exporter' }));
});

socket.on('data', (raw) => {
  const msg = JSON.parse(raw.toString());
  if (msg.type === 'request.accounts') {
    // fetch accounts from local DB and respond (watch-only data)
    socket.write(JSON.stringify({ type: 'accounts.response', accounts: [] }));
  }
});
      

Design plugins to be optional — Trezor Suite should operate fully without them. Keep plugin communication local and authenticated, and consider enterprise packaging and code-signing for distribution.

Core Features of Trezor Suite

Unified Portfolio

Trezor Suite aggregates balances and transactions across supported blockchains, giving you a clear picture of your holdings without exposing sensitive data.

Transaction Signing & Verification

Suite constructs transactions and the Trezor device displays human readable details — amount, recipient, and fee — requiring manual confirmation to sign.

Manager & Firmware

Install coin modules, apply verified firmware updates, and check device health using the Suite manager to keep the device authentic and up to date.

Watch-only Modes

Export XPUBs to create monitoring-only accounts for auditors and integrations without exposing signing capabilities.

Security Architecture

Trezor Suite follows a security-first model: private keys are generated on-device and never leave it. The Suite and any plugin may prepare data, but signatures are produced only by the hardware device after you verify details on its display. This model mitigates host-based threats and enforces explicit user approval for sensitive actions.

Additional protections: signed firmware updates, device attestation, PIN protection for physical access, and optional passphrase-protected hidden wallets. Combine these controls with secure seed storage and responsible software hygiene for a robust security posture.

Advanced Workflows & Enterprise Recommendations

For enterprise or high-value personal custody, Trezor Suite supports advanced patterns: air-gapped signing, multisig setups, audited watch-only exports, and plugin-enforced approval policies. Use a hardened signing workstation, retain multiple offline seed backups (ideally metal), and document recovery and rotation procedures. Trezor Suite can be part of a layered custody plan combining organizational controls, role separation, and periodic audits.

When integrating plugins for enterprise, ensure code signing, internal reviews, and secure distribution channels so that only authorized builds run in production environments.

Privacy Considerations

Trezor Suite minimizes telemetry by default and performs portfolio calculations locally. When using third-party market feeds or exchange partners, you may disclose limited metadata to those services for pricing and routing. If privacy is a primary requirement, configure Suite to limit telemetry, use trusted or local market sources, and consider routing traffic through privacy-preserving networks.

Note: blockchain transactions are public; Suite protects keys and reduces metadata leakage but cannot anonymize on-chain activity entirely. Use privacy-focused techniques and services as needed.

Troubleshooting

Device not detected

Try a different USB cable and direct port. Restart Suite and the device. On some OSs, give permission to the Suite app. If issues persist, try another computer to rule out host problems.

Firmware update interrupted

If update fails, follow Recovery mode instructions in Suite. You may need your recovery seed to restore — never proceed to restore without the seed available.

Seed restore problems

Ensure words are entered in exact order and spelling. If you used a passphrase originally, provide it during restore to access the correct wallet.

Plugin errors

If a plugin misbehaves, disable it and restart Suite. Only run audited and signed plugins in production. Review logs and isolate problematic builds.

Frequently Asked Questions

Can I use Trezor Suite without a device?

You can use watch-only mode with exported public keys, but sending or signing transactions requires a connected Trezor device.

Is it safe to add plugins?

Plugins can be safe if designed to respect the Suite security model. Use signed, audited plugins and avoid any plugin that requests seeds or private keys.

What if I lose my seed?

If you lose the seed but have the device, generate a new seed and transfer funds. If both device and seed are lost, funds cannot be recovered.
