Trezor Suite^® – Getting Started^™ Developer Portal

Introduction

Welcome to the Trezor Suite Developer Portal walkthrough. Whether you're building a web wallet, a merchant integration, or an experimental dApp, this guide will get you from zero-to-running. We'll cover hardware basics, local setup, the key libraries and endpoints you’ll use, and — most importantly — where to find authoritative resources and sample code.

Who this is for

Developers with basic familiarity with JavaScript or Rust who want to integrate Trezor hardware wallets into apps. If you manage security-sensitive signing flows, treat the steps below as a checklist to reduce tribal knowledge and avoid common mistakes.

Quick start — Hardware + Suite setup

Before you start coding, get the hardware and official Suite app working. The typical flow is:

1. Unbox your Trezor device and follow the official first-time setup in Trezor Suite.
2. Install Trezor Suite (desktop or web) and confirm firmware is up to date.
3. Familiarize yourself with the Suite UI and with connecting via Trezor Connect if building web integrations.

Practical tips

Device readiness

Always initialize a fresh device for development or use a dedicated test device. For transaction testing use testnets (when supported) and never send real funds while experimenting.

Local environment

For web dev, a modern Node.js LTS version, a simple bundler (Vite/webpack), and the latest Trezor Connect package are recommended. For Suite development, check the monorepo and docs for building the Suite client locally.

APIs & SDKs — what you'll use

Trezor exposes developer-friendly tools and libraries. The main building blocks:

• Trezor Connect — a JS-based bridge for requesting public keys, signatures, and user confirmations in secure flows.
• Trezor Suite docs — guides and package docs for Suite internals and Connect methods.
• Blockbook / backends — for indexing and transaction history when building wallet UIs.

Example: simple Connect usage (web)

<!-- include via npm or CDN -->
<script type="module">
import TrezorConnect from 'trezor-connect';

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

async function getPublicKey() {
  const res = await TrezorConnect.getPublicKey({ path: "m/44'/0'/0'/0/0" });
  if (res.success) console.log(res.payload.xpub || res.payload);
  else console.error(res.payload.error);
}
</script>

Developer workflows

Local Suite development

If you're contributing to Trezor Suite or want deep customizations, clone the Suite monorepo and follow the package readmes. Build systems and linting are included — expect to run local dev servers and follow the repo's contribution guide.

Third-party wallet integration

When integrating Trezor into existing wallets (MetaMask-style flow), rely on Connect for secure user prompts and signatures, and use the recommended backend for chain data. Respect user privacy by asking only the data you need and by requesting permissions clearly.

Release and QA checklist

• Test firmware compatibility across device models.
• Verify flows on all supported OSes and browsers.
• Include clear error-handling for user cancelations and device disconnects.

Security & best practices

Security is non-negotiable. Keep private keys off your servers, use the hardware device for signing, and never log secrets. For UX, make prompts explicit so users understand what they're approving.

Key security rules

• Never request the seed or private key programmatically.
• Use official libraries and keep them updated.
• Validate addresses locally and show human-readable confirmations to users.

Troubleshooting & support

For breaking issues, reproduce with minimal code, check the official docs and GitHub issues, and follow the project's issue templates. When filing bugs, include environment, device model, firmware version, and a reproducible snippet.

Community and reporting

Use the official developer pages and GitHub repositories for reporting and PRs. For urgent device or security concerns, follow the official escalation paths listed on the developer portal.
