Developer Portal — Quickstart & Integration Guide

Overview

Trezor Suite is the official desktop & web app for managing Trezor hardware wallets. This developer-focused guide walks through the architecture, common integration paths (Trezor Connect, Suite APIs), setup steps, security considerations, and quick examples so you can integrate Trezor support into your wallet, exchange, or dApp.

What you’ll find in this guide

• High-level architecture and components.
• How to use the Trezor JavaScript SDK (Trezor Connect).
• How to run the Trezor Suite monorepo locally for development.
• Security best practices when talking to hardware wallets.
• 10 official Trezor links for reference and further reading.

Core components

Trezor Suite

Desktop & web application used by end users to manage accounts, sign transactions and access advanced features.

Trezor Connect

High-level JavaScript API and bridge used by third-party apps to request public keys, sign messages and sign transactions using a connected Trezor device.

Trezor Bridge (legacy)

Historically provided native communication; the ecosystem is transitioning so check the official docs for current recommendations.

Developer workflow (quick)

1. Read the Trezor Suite docs and Connect docs (links below).
2. Clone the trezor-suite monorepo from GitHub for local dev and examples.
3. Install dependencies, run the local Suite or Connect demo.
4. Use Connect Explorer to prototype calls safely in the browser.
5. Follow security best practices: never expose private keys, always validate addresses & origins.

Local development: run the Suite

Official monorepo contains the code for Connect, Suite (desktop & web), and mobile clients. Running it locally is the best way to experiment and inspect how Suite interacts with the device and the JS SDK.

git clone https://github.com/trezor/trezor-suite.git
cd trezor-suite
# follow the repo README for install & start scripts

Security: quick checklist

• Use HTTPS for all web endpoints and verify origins when calling Trezor Connect.
• Prompt users for confirmation on sensitive actions and show human-readable transaction summaries returned by the hardware wallet.
• Keep firmware and Suite up to date; check release notes for breaking changes.
• Do not rely on client-side heuristics to verify ownership — prefer device-signed data where possible.

Examples

Simple Trezor Connect example (JS)

Use the official Connect library for common operations (get xpub, sign tx, get address):

import TrezorConnect from 'trezor-connect'

TrezorConnect.getPublicKey({ path: "m/44'/0'/0'" })
  .then(res => console.log(res))
  .catch(err => console.error(err))

Integration tips

Testing

Use a combination of unit tests and an actual device (or emulator) for integration tests. The GitHub repo includes examples and test helpers.

Compatibility

Be mindful of supported coin protocols and signing capabilities. Refer to Trezor Suite and Connect docs for the latest supported chains and features.

Official resources (10 links)

Below are the authoritative Trezor links you’ll want bookmarked while developing. Each is the primary source for that topic.

Best practices & closing thoughts

Design for explicit consent

Always model flows so the device prompts display exactly what the user expects. Device confirmations are the single most important UX & security boundary when integrating hardware wallets.

Keep dependencies up to date

Follow the Suite releases and Connect changelogs. When upgrading, run your integration tests against the new Suite/Connect to catch breaking changes early.

Further reading

Use the official docs and GitHub repo to dig into package READMEs and implementation details — the codebase itself is a powerful reference for patterns and recommended flows.
