Trezor Suite® – Getting Started™ Developer Portal

A compact, richly colored developer-facing presentation that walks engineers, integrators, and security teams through connecting, developing, and shipping with the Trezor platform.

Overview

Purpose

This document is a portable HTML presentation for engineers and product teams who want to get started with the Trezor Suite developer experience. It is written to be copy-pasteable into a slide generator or used directly as a reference page. The goal is to make onboarding fast and to highlight the developer tools, workflows, and security guardrails that matter most.

Who should read this

Developers, devops engineers, product managers and security reviewers who will integrate hardware wallet support, implement signing flows, or use Trezor’s tools in their wallets and services.

How to use this file

Open in a browser for a colorful single-page presentation. Use the headings (h1–h5) to break into slides in any HTML-aware slide tool (e.g., Reveal.js or PowerPoint via HTML import).

Prerequisites

What you'll need

Developer account and keys

Register for developer resources on Trezor’s Developer Portal and keep your API keys and test accounts in a secure vault. Perform development on testnets whenever possible before hitting mainnet.

Install & Setup

Installing Trezor Suite

Download and install Trezor Suite for desktop from the official site, or use the web version at suite.trezor.io. For development prefer the desktop app when USB passthrough is needed.

Command-line tools

Some common packages you'll encounter:

Quick setup commands

npm init -y
npm install trezor-connect
# or
pnpm add trezor-connect

Load trezor-connect in your web or electron app and initialize it as documented in the SDK README for the exact configuration values.

Connect a Device

USB and WebUSB

Trezor devices use USB/HID or WebUSB connection channels. In browsers, WebUSB allows direct communication; in desktop and Electron apps the Trezor Bridge provides a secure channel. Always use the official Trezor Bridge for legacy browsers.

Basic connection flow

  1. Install Trezor Suite or Trezor Bridge.
  2. Plug the device in and confirm the on-device prompt.
  3. Initialize or unlock the device (enter PIN if set).
  4. Use trezor-connect to request allowed methods (getPublicKey/signTx/etc.).

Sample connection snippet

import TrezorConnect from 'trezor-connect';

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

const resp = await TrezorConnect.getPublicKey({
  path: "m/44'/0'/0'"
});

This initializes the library — the device will ask the user to confirm key export on the screen.

Developer Resources

Primary documentation

Use the official developer docs for reference on message formats, transport options, and firmware compatibility. Bookmark the Trezor Developer Portal and GitHub repositories for the latest examples and issue trackers.

Community and support

For questions use GitHub issues, community forums and the official blog for announcements. When filing bugs, attach logs and clear reproduction steps. Maintain a tight feedback loop between device firmware and SDK releases.

APIs & SDKs

Trezor Connect (Web + JS)

Trezor Connect provides a high-level API to invoke device operations (getPublicKey, signTransaction, signMessage, etc.). It handles transport, popup flows, and manifest enforcement.

Low-level protobuf / transport

Advanced integrations may use the raw protobuf messages to implement signing flows or to support custom coin logic. Use these only if you have deep familiarity with the device protocol and cryptographic operations.

Versioning concerns

Always check SDK release notes and firmware compatibility matrices before upgrading. Use semantic version pinning and testing lanes to avoid breaking users in production.

Examples & Code Snippets

Sign a message

// Example: signMessage with trezor-connect
const result = await TrezorConnect.signMessage({
  path: "m/44'/0'/0'/0/0",
  message: 'Hello from Trezor!'
});

if (result.success) {
  console.log('signature', result.payload.signature);
}

Signing a transaction (high level)

High-level signing usually requires preparing inputs, outputs and passing common transaction fields to the device. For complex coin types consult the SDK docs and provided helpers for serialization.

Pro tips

Security Best Practices

Least privilege & explicit consent

Request only the exact operations you need. Show human-readable summaries of transactions and ask for on-device confirmation for critical operations. Treat the hardware wallet as the single source of truth for private keys.

Key management

Do not store private keys on servers. Use hardware signing flows for custody. When you use derived keys, follow the recommended BIP standards and store derivation paths with user accounts.

Auditing & logging

Keep signed operation logs (not raw secrets) and timestamp verification events. When interacting with user devices, record the minimal set of metadata needed for debugging while respecting user privacy.

Testing & Deployment

Testnet and CI

Run integration tests against testnets and in CI environments that can simulate or attach Trezor devices (or hardware emulators). Automate smoke tests that include device connectivity and signing for critical flows.

Rollout strategy

Canary rollouts and staged feature flags help reduce risk. Monitor crash rates and user support volume when releasing SDK or workflow changes that touch device interactions.

FAQ & Troubleshooting

Device not recognized

Check cable quality, USB ports and Trezor Bridge installation. Ensure the user has unlocked the device and accepted the connection prompt.

Signature mismatch

Confirm derivation paths and address formats. Confirm that the device firmware and SDK versions are compatible.

Where to file issues

Use the Trezor GitHub repos or the official support channels. Provide OS, firmware, SDK versions and a minimal reproduction case.
