Trezor Suite® – Getting Started™ Developer Portal

A concise, developer-friendly guide to integrating with Trezor Suite and using the Developer Portal. This post focuses on practical steps, security best practices, and useful links to official resources.

Introduction

Welcome to the Trezor Suite Developer Portal primer. Whether you are building wallet integrations, automation tools, or hardware-assisted signing flows, this guide walks through the essentials: where to start, how to authenticate, sample code snippets, and security considerations. We include ten official links (styled for clarity) to speed up your journey.

Who is this for?

Developers comfortable with JavaScript, TypeScript, or backend languages who want to integrate the Trezor Suite experience into their applications. Familiarity with cryptography basics (keys, signatures, derivation paths) is helpful but not mandatory.

Why use Trezor Suite & Developer Portal?

Trezor Suite provides a secure, user-first interface for managing hardware wallets. The Developer Portal offers documentation, APIs, and tools to integrate Trezor features into web and native apps. Using these resources helps keep private keys off your servers and leverages audited firmware and signing workflows.

Core concepts

Device vs. Suite

The hardware device holds the seed and signs transactions. Trezor Suite (desktop and web) is the UI and bridge that talks to the device. Your integration typically talks to Suite or communicates directly using the Trezor Connect SDK.

Deterministic wallets

Trezor uses hierarchical deterministic (HD) wallets. Your integration should respect standard derivation paths (BIP32/BIP44/BIP84) and avoid exporting private material from the device.

Getting started — step-by-step

1. Explore the Developer Portal

Start by visiting the Developer Portal and official docs to find API references, SDKs, and quickstart guides. Bookmark the official pages — we list them below for convenience.

2. Use Trezor Connect (web integrations)

Trezor Connect is the recommended JavaScript library for browser integrations. It handles device discovery, permissions, and the signing flow. Install it via npm and add the initialization snippet.

// npm install trezor-connect
import TrezorConnect from 'trezor-connect';

TrezorConnect.init({
  manifest: {
    email: 'dev@example.com',
    appUrl: 'https://your-app.example'
  }
});

3. Build a simple signing flow

Example: request an address and sign a message (JavaScript):

const response = await TrezorConnect.getAddress({
  path: "m/44'/0'/0'/0/0",
  showOnTrezor: true
});

if (response.success) {
  console.log('Address:', response.payload.address);
}

const sign = await TrezorConnect.signMessage({
  path: "m/44'/0'/0'/0/0",
  message: 'Authorize login'
});

if (sign.success) console.log('Signature:', sign.payload.signature);

4. Test on emulator and real hardware

Use the Suite's testing tools and the device emulator (if available) before asking users to connect real hardware. This reduces friction and avoids accidental device resets.

Security best practices

Never request private keys

Use the signing APIs; never request that users export their seed words or private keys. Any flow that asks for seed words is malicious and should be reported.

Manifest & origin checks

When using Trezor Connect, register a manifest including an application URL and contact email. During development and production, confirm that your app origin and manifest details remain accurate.

Limit permissions & verify addresses

Ask the device only for the data you need. When building transaction flows, always require the user to verify addresses and amounts on the device screen (showOnTrezor).

Advanced topics

Backend integrations and PSBT

For server-assisted workflows, use partially signed bitcoin transactions (PSBT) and keep signing steps client-side. Your backend can assemble unsigned PSBTs and send them to the client for device signing.

Multi-account & u2f-like flows

If you support multiple accounts per user, store only public keys or XPUBs server-side. Never store private keys. Consider using U2F/WebAuthn for session authentication while leveraging device signatures for transaction approval.

Troubleshooting & support

Common issues

Where to ask for help

Use the official support pages and developer forum for reproducible bug reports. Include logs and a minimal reproducible example when opening issues.

Sample HTML snippet (embed)

Use this snippet to add a quick-start card on your docs page. It uses Trezor Connect's init call and a link to the Developer Portal.

<!-- Quick-start card -->
<div class="trezor-quickstart">
  <h4>Connect your Trezor</h4>
  <button id="connect">Connect Trezor</button>
</div>

<script src="https://connect.trezor.io/8/trezor-connect.js"></script>
<script>
  TrezorConnect.init({manifest:{email:'dev@example.com', appUrl:'https://your-app.example'}})
  document.getElementById('connect').addEventListener('click', async ()=>{
    const r = await TrezorConnect.getFeatures();
    console.log(r);
  })
</script>

Wrap-up and next steps

Integrating with Trezor Suite and the Developer Portal gives your users a safer way to control keys and sign transactions. Start small: implement an address-read and message-sign flow, then expand to transaction PSBT signing and multi-account support. Keep security at the forefront — never request seeds, and require on-device verification for sensitive actions.
