Trezor Suite® – Getting Started™ Developer Portal

A pragmatic, developer-first walkthrough for integrating with Trezor Suite — setup, SDKs, APIs, security best practices, and ready-to-run examples.

On this page

Overview

The Trezor Suite® Developer Portal is designed to accelerate integrations that interact with Trezor hardware and the Trezor Suite application. This guide walks you from initial setup through secure integration patterns and provides concrete code examples you can copy and run.

Quick fact: Trezor Suite is the official desktop and web application for managing Trezor hardware wallets; developer resources and API references are available on the official Trezor docs site. See the official docs in the Resources section below. :contentReference[oaicite:2]{index=2}

Prerequisites & Setup

1. Hardware & Software

Get a supported Trezor device (Model T or latest Safe series). Install Trezor Suite (desktop or web) and confirm firmware is up to date before attempting integration. Always verify downloads from the official Trezor website or GitHub. :contentReference[oaicite:3]{index=3}

2. Developer Tools

  • Node.js (LTS) and npm/yarn
  • Basic knowledge of WebUSB / WebHID where applicable
  • Familiarity with Ethereum/BTC signing flows if building wallet integrations

3. Official docs

Bookmark the official Trezor Suite documentation and developer pages — they contain API references (e.g., Trezor Connect), SDK guidance, and security notes. Links are repeated in the Resources section and embedded throughout this article for convenience. :contentReference[oaicite:4]{index=4}

Architecture & Integration Points

Trezor Suite + Host App Interaction

Integration with Trezor typically happens in one of two ways:

  • Via Trezor Connect: a stable API for third-party wallets and dApps to request signatures, public keys, and authentication without exposing private keys. :contentReference[oaicite:5]{index=5}
  • Direct Suite Integration: for deep integrations (for example, building a plugin or embedding Suite UI), consult the Suite docs for architecture and packaging details. :contentReference[oaicite:6]{index=6}

How messages flow

Typical flow: user action → host app calls Trezor Connect or Suite API → device prompts user to confirm on the hardware → signed data returns to the app → transaction broadcast. Keep this chain auditable and user-facing confirmations clear.

Best integration tip

Treat the hardware prompt as the ground truth: always display the same human-readable details the device shows so users can verify correctness before confirming.

SDKs & Examples

Trezor Connect quick start

Trezor Connect gives you a simple JavaScript API. Install it via npm and initialize it inside your app; then request operations like `getPublicKey`, `signTransaction`, or `ethereumSignMessage`. Example snippet: 

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

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

const res = await TrezorConnect.getPublicKey({ path: "m/44'/60'/0'/0" });
console.log(res);

Integration examples

  • Wallet: request xpubs and show a read-only account view
  • DApp: sign messages and transactions without ever taking keys off-device
  • Merchant integration: verify merchant payment addresses using hardware verification

Bundling with Trezor Suite

If you aim to contribute to Suite or ship a custom build, the Suite docs explain the monorepo layout, packaging, and UI conventions. Consult the official docs frequently while developing. :contentReference[oaicite:7]{index=7}

Security Best Practices

Principle: minimize attack surface

Keep key operations on the hardware. Never export or log private keys. Use hardware verification dialogs to confirm human-readable transaction fields. These rules preserve user trust and reduce liability.

Manifest & origin policies

When using Trezor Connect, provide a clear `manifest` with a valid email and app URL; this enables the Trezor team to contact you about abuse and helps users verify the authenticity of your integration.

Supply chain hygiene

Download Suite and firmware only from official channels and verify signatures where provided. If you ship an integration, include clear instructions for users to verify they’re interacting with the official Trezor Suite or your verified integration. :contentReference[oaicite:8]{index=8}

UX & security

Present transaction details in plain language. Avoid truncating critical fields that the device shows. If an operation modifies spending amounts or fees, show before-and-after comparisons.

Troubleshooting & QA

Common integration hiccups

  • Device not detected: ensure browser permissions for WebUSB/WebHID and that Suite is not blocked by an OS driver.
  • Stale firmware: prompt users to update firmware in Suite before proceeding.
  • Signature mismatch: verify canonical serialization and chain parameters on both ends.

Logging & user support

Log non-sensitive operation metadata (timestamps, operation type, network) to help debug while never logging keys or sensitive payloads. Provide users a one-click "report issue" utility that includes diagnostic metadata (not private data).

FAQ

Can I use Trezor with mobile dApps?

Yes — Trezor has mobile-compatible flows (e.g., mobile Suite and WalletConnect support). Evaluate whether your user base needs walletconnect-style bridges or direct Suite interactions.

Is Trezor Connect the recommended path?

For most third-party apps and dApps, Trezor Connect is the easiest and safest path to requesting signatures and public keys. For deep product integrations or contributions to Suite itself, follow Suite’s developer docs. :contentReference[oaicite:9]{index=9}

Resources & Official Links

Below are official references you should keep open while building. (The main Trezor Suite documentation is the primary technical source.)
