Trezor Suite® – Getting Started™ Developer Portal

A concise, developer-friendly walkthrough to integrate & test Trezor Suite — focused on web integrations, UX, and security best practices.

Overview

Welcome to the Trezor Suite Developer Portal guide. This presentation will help you understand key concepts to quickly integrate, test, and ship Trezor-compatible features in your dApp or service. We cover the essentials: architecture, connecting devices, common flows, and developer tips for a smooth Trezor Suite integration.

Who is this for?

Frontend engineers, wallet integrators, and product managers who want to offer secure hardware wallet flows leveraging the Trezor Suite ecosystem.

Quick Start — 6 Steps

  1. Read the Docs: Start at the official Developers page for API references and SDKs.
  2. Install Trezor Suite: Use the Trezor Suite app or web suite to test UI flows with a real device or emulator.
  3. Connect Device: Prompt users to connect via WebUSB or Bridge. Detect devices and present device state early.
  4. Mock Accounts: Create test accounts and implement a sandbox network for signing tests.
  5. Implement UX Patterns: Follow best practices for prompts, clear error states, and step-by-step confirmations.
  6. Security Review: Perform threat modeling, check firmware compatibility, and run user acceptance tests with real devices.

Sample connection snippet

// pseudo-example: request connection to Trezor Suite const {requestDevice} = window.TrezorConnect || {}; if(requestDevice){ requestDevice().then(device => console.log('connected', device)); }

Best practices

  • Never collect sensitive seeds or recovery phrases in your app.
  • Always show human-readable confirmations for transaction details.
  • Gracefully handle device disconnects and firmware mismatches.

Architecture & Integration Patterns

Client-side

The common pattern is a lightweight client which communicates with Trezor Suite or Trezor Connect via WebUSB/Bridge. Keep cryptographic operations on-device where possible.

Server-side

Servers should act as stateless helpers (broadcasting signed transactions, fetching chain data). Avoid storing private keys — the Trezor device signs offline.

Error handling checklist

  • Device not found — provide clear steps to install Bridge/enable WebUSB.
  • Unsupported firmware — show upgrade instructions and link to official firmware page.
  • Timeouts — suggest user re-connect or retry with diagnostics link.

FAQ

Q: What is Trezor Suite and how does it relate to developer work?

Trezor Suite is the official desktop & web interface for Trezor hardware wallets. For developers, it exposes integrations and a flow for connecting devices, signing transactions, and verifying addresses securely.

Q: Do I need a physical device to develop?

While emulators and mocking tools exist, testing on a physical Trezor device is strongly recommended before shipping.

Q: Which connectivity options are supported?

WebUSB, Trezor Bridge, and native integrations via desktop Suite are the primary options. Always offer fallback messaging.

Q: Where can I find API references?

See the official Developers and Docs pages for SDKs, examples, and the latest API references.

Q: How should I display transaction details?

Show amount, recipient, fees, and an explanation of ledger entries. Use short confirmations and require explicit user approval on the Trezor device.
