Trezor Suite® – Getting Started™ Developer Portal

A pragmatic walkthrough for developers integrating with Trezor Suite and Trezor hardware. Includes setup, API basics, security tips, and links to official resources.

Introduction

Welcome! If you're building integrations with Trezor hardware wallets or embedding Trezor Suite® features into your application, this guide gives you the practical "getting started" steps — from installing the Suite to using Trezor Connect APIs and best practices for secure integrations.

Official resources (quick reference)

Bookmark these official pages — they will be your primary references while developing and testing:

• Trezor Suite — official page
• Trezor Suite documentation (developer docs)
• Trezor Connect overview
• Trezor Connect — GitHub
• Download & verify Trezor Suite
• Congrats & Start page — getting started
• Getting to know Trezor Suite — user guide
• Device-specific: Trezor Safe 5 setup
• Trezor Suite — Google Play
• Trezor Suite — App Store

1. Prerequisites — what you need

Before integrating with Trezor Suite or Trezor Connect, make sure you have:

• A supported Trezor device (model compatibility is documented in the guides).
• Trezor Suite installed on your desktop or the mobile app for testing flows.
• Basic web development environment (Node.js, npm/yarn) and a local HTTPS dev server if you plan to use Trezor Connect in-browser (popups require secure contexts).

Download & verify

Always download Suite and any firmware from official sources and verify signatures as described on the Trezor site. This prevents tampered installers and fosters safe testing.

2. Quick install & run (developer steps)

Install Trezor Suite

Follow the official download & verify steps and install the desktop app (recommended) or run the web app. Connect your device via USB or Bluetooth (device dependent).

Local dev with Trezor Connect

To try Trezor Connect in a quick prototype, install the NPM package and serve your app over HTTPS:

npm install trezor-connect
# in your code
import TrezorConnect from 'trezor-connect';

TrezorConnect.init({ connectSrc: 'https://connect.trezor.io/8/' });

When you call `TrezorConnect.getPublicKey` or `TrezorConnect.signTransaction`, a secure popup will open and the user will confirm on-device. For production, always use the latest recommended `connectSrc` and follow the security guidance in the docs.

3. Example: Get public key (JavaScript)

Minimal example to request an xpub or single public key:

import TrezorConnect from 'trezor-connect';

async function getKey() {
  await TrezorConnect.init({ manifest: { email: 'dev@example.com', appUrl: 'https://yourapp.example' }});
  const result = await TrezorConnect.getPublicKey({ path: "m/44'/0'/0'/0/0" });
  if (result.success) {
    console.log('Public key:', result.payload.publicKey);
  } else {
    console.error('Trezor error:', result.payload.error);
  }
}

Notes

• Always set a `manifest` when initializing to comply with Connect requirements.
• Use strict path derivation and show valid descriptions in your UI so users recognize requested operations.

4. Security best practices (non-negotiable)

Trezor hardware provides a very high standard for private key protection. As an integrator you must not undermine that:

• Never request private keys or attempt to transmit sensitive user secrets to your servers.
• Use on-device confirmation flows for signing — do not try to emulate or shortcut user confirmation.
• Enforce HTTPS and Content Security Policy (CSP) for web apps that use Connect popups.
• Offer users clear, human-readable descriptions of transactions (amount, destination, network fees) before calling sign APIs.

5. Troubleshooting checklist

Common issues

• Popup blocked — ensure browser allows popups from your host and `connect.trezor.io` is reachable.
• Device not recognized — check USB cables, try Trezor Bridge if using older setups, update firmware if suggested.
• Signature mismatch — double-check the transaction fields you sign; show full human-readable summary to the user.

6. Where to go next (advanced topics)

Once you have basic public-key and signing flows working, explore:

• Connecting Suite features like portfolio and swap integrations.
• Using the Connect library in mobile/web hybrid flows if you support WalletConnect or similar.
• Contributing back to open-source Trezor projects on GitHub (issue reports, integration examples).

7. Example integration pattern (server + client)

High-level flow

1. Client requests an unsigned transaction payload from your server (server prepares network-specific fields).
2. Client invokes Trezor Connect sign function; user confirms on device.
3. Signed transaction is returned to the client and posted to your server (or broadcast directly).

// pseudo
Client -> GET /tx-prepare -> Server
Client -> TrezorConnect.signTransaction(tx)
Trezor -> user confirms -> signedTx returned
Client -> POST /broadcast signedTx -> Server broadcasts

Conclusion

Integrating with Trezor Suite and Trezor Connect is straightforward when you follow the official docs, keep your dev environment secure, and honor the on-device confirmations. Use the 10 official links at the top of this article for downloads, developer docs, and platform-specific guides.
