Trezor Suite is the trusted application for securely managing cryptocurrencies with your hardware wallet. This guide walks you through setup, plugin integration, security best practices, advanced workflows, and day-to-day usage so you can confidently manage assets with Trezor Suite.
Throughout this guide you’ll find practical steps and plugin examples to help Trezor Suite integrate with your personal workflow or organization. The content below covers everything from first-time setup to enterprise-grade custody patterns.
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.
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.
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.
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.
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.
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.
Trezor Suite aggregates balances and transactions across supported blockchains, giving you a clear picture of your holdings without exposing sensitive data.
Suite constructs transactions and the Trezor device displays human readable details — amount, recipient, and fee — requiring manual confirmation to sign.
Install coin modules, apply verified firmware updates, and check device health using the Suite manager to keep the device authentic and up to date.
Export XPUBs to create monitoring-only accounts for auditors and integrations without exposing signing capabilities.
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.
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.
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.
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.
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.
Ensure words are entered in exact order and spelling. If you used a passphrase originally, provide it during restore to access the correct wallet.
If a plugin misbehaves, disable it and restart Suite. Only run audited and signed plugins in production. Review logs and isolate problematic builds.
You can use watch-only mode with exported public keys, but sending or signing transactions requires a connected Trezor device.
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.
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.
