Trezor Suite® – Getting Started™ (Developer Portal)

Overview

Welcome to the Trezor Suite® – Getting Started™ Developer Portal. This page gives a concise, practical introduction for developers and integrators who want to work with the Trezor Suite environment. Whether you're building wallets, integrations, or developer tools, the Trezor Suite docs and APIs provide secure device interactions, transaction signing, and account management. Throughout this guide we mention Trezor Suite, Trezor/Suite and trezor suite to emphasize integration points and common search terms.

What you will learn

• How to prepare your environment for Trezor Suite development.
• Basic flow: connect, enumerate, request public keys, and sign transactions.
• Where to find SDKs and sample code for Trezor/Suite usage.
• Best practices for secure integrations with trezor suite devices.

Prerequisites

Before you start, make sure you have:

1. A supported Trezor device and latest firmware.
2. Access to the Trezor Suite desktop or web client for testing.
3. Node.js (LTS recommended) for running sample apps and SDK examples.
4. Familiarity with web USB / native bridge approaches if you use Trezor/Suite across platforms.

Reminder: this guide references Trezor Suite and Trezor/Suite and trezor suite for clarity and searchability.

Quick start (code example)

The example below shows a minimal flow to request a public key and ask the device to sign a message. Replace placeholders with your environment-specific values.

// pseudo-code / simplified example
import { connect } from 'trezor-connect';

async function start() {
  await connect({ manifest: { email: 'dev@example.com', appUrl: 'https://your.app' } });
  const res = await connect.getPublicKey({ path: "m/44'/0'/0'/0/0" });
  if (res.success) {
    console.log('pubkey', res.payload.publicKey);
  } else {
    console.error('error', res.payload.error);
  }
}
start();

Note: in many environments, Trezor Suite or Trezor/Suite will proxy device communication. Use the official SDKs or libraries shown in the Trezor Suite developer docs for reliable integration.

API & SDKs

The Trezor/Suite ecosystem provides several libraries and SDKs for web and native apps. Use platform-specific bindings for better UX: web USB or bridge for browser apps and native bindings for desktop apps. When referencing the API, always verify compatibility between your chosen SDK and the installed Trezor Suite version.

Security best practices

Security is the core of the Trezor Suite and trezor suite design. Follow these principles:

• Never log sensitive responses from the device.
• Use manifest and app identification when initializing Trezor/Suite connections.
• Request the minimum required permissions for any transaction or key action.
• Validate all user-facing data before requesting signing on the device.

Troubleshooting tips

If the device does not appear in Trezor Suite, try:

• Restarting the Trezor Suite application and reconnecting the device.
• Ensuring the device firmware is up-to-date and unlocked.
• Confirming browser permissions for Trezor/Suite (web USB) or bridge connectivity.

These basic checks will resolve most common connection issues when working with Trezor Suite or trezor suite integrations.
