Trezor Suite® – Getting Started™ Developer Portal

What is Trezor Suite?

At its core, Trezor Suite is the official desktop and web application for managing Trezor hardware wallets. It provides wallet management, transaction history, portfolio tracking, and secure signing flows for supported assets. The Suite is the recommended user-facing integration point for most hardware-wallet interactions. :contentReference[oaicite:1]{index=1}

Developer overview

The developer experience splits into two common integration patterns:

• Embed Trezor Connect in a web app to let users sign transactions and provide account authorization via the device.
• Extend or contribute to Trezor Suite itself — build Suite packages, plugins, or improved UX components using the Suite monorepo and documentation. :contentReference[oaicite:2]{index=2}

Architecture (high-level)

Typical elements you'll encounter:

Trezor device

The hardware wallet stores seed & private keys and performs cryptographic signing on-device.

Trezor Suite

The Suite acts as a rich UI layer and orchestration engine for signing flows, coin discovery, and portfolio tracking. You can download and verify official Suite builds from the Trezor site. :contentReference[oaicite:3]{index=3}

Trezor Connect

Trezor Connect is the recommended JavaScript SDK for web and Electron apps. It exposes endpoints for public keys, address derivation, transaction signing, and authentication operations. Use Connect for simple web wallet integrations and third-party dApp interactions. :contentReference[oaicite:4]{index=4}

Quick start — what you need

1. A Trezor hardware device (Model One / Model T / Safe 7).
2. The latest Trezor Suite or the Connect SDK for web use. :contentReference[oaicite:5]{index=5}
3. Developer tools: Node.js, a modern browser, and for Suite contributions, a local monorepo clone from the official Trezor GitHub. :contentReference[oaicite:6]{index=6}

Example: Trezor Connect (minimal web example)

Install or include the SDK and call a simple public-key request. This example shows the canonical JavaScript flow for a web wallet.

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

// initialize (web) — options can vary by environment
TrezorConnect.manifest({
  email: 'dev@example.com',
  appUrl: 'https://your-app.example'
});

// request account public key
async function getAccount() {
  const response = await TrezorConnect.getPublicKey({
    path: "m/44'/0'/0'/0/0",
    coin: 'BTC'
  });

  if (response.success) {
    console.log('xpub / pubkey:', response.payload);
  } else {
    console.error('Trezor Connect error', response.payload.error);
  }
}

Notes & best practices for Connect

• Always use the manifest API to identify your app to the Connect popup.
• Prefer explicit derivation paths and coin identifiers to avoid accidental mixed-network operations.
• Design UI flows for the asynchronous device confirmations — keep UX non-blocking and informative.

Security & verification

When integrating with hardware wallets, follow these essentials:

• Verify downloads: only use Suite binaries from the official site or verified GitHub releases and follow the published verification instructions. :contentReference[oaicite:7]{index=7}
• Never transmit seeds: seeds and private keys must remain on-device. Signing-only flows keep sensitive material isolated.
• Be phishing-aware: users can be directed to lookalike pages. Emphasize correct domain names and verification steps in your UX.

Deprecations & migration notes

Note: Trezor has published changes and deprecations around legacy components—review the official deprecation notes if your integration relies on older bridges or libraries. :contentReference[oaicite:8]{index=8}

Contributing to Trezor Suite

If you plan to extend Suite itself:

• Fork and clone the official repo on GitHub to begin; follow the monorepo README and package conventions. :contentReference[oaicite:9]{index=9}
• Use the Suite docs for package-level guidance and local development commands. :contentReference[oaicite:10]{index=10}
• Respect the project’s security checklist and review policies when submitting PRs.

Testing & CI

For reliable integrations, build automated tests that mock Trezor responses where possible and keep a small set of integration tests that exercise actual hardware (marked and gated in CI to avoid exposing private keys).

UX guidance (developer to product handoff)

Work closely with product/UX to ensure:

• Flows show clear device prompts and statuses.
• Retries and error messages map to actionable steps (e.g., “Reconnect device”, “Open Trezor Suite”, “Confirm on device”).
