Trezor Suite® Getting Started™ — Developer Portal

Overview

This guide helps developers get started with Trezor Suite and the developer-facing tools surrounding the Trezor ecosystem. It’s written for engineers building integrations, wallets, or services that need to interact with Trezor devices or the Suite application. Expect setup steps, integration patterns, example code snippets, and links to official docs and developer portals.

Why this guide

Developers often want an actionable path: install, connect a device, run a sample integration, and understand the security tradeoffs. This guide condenses that path into an opinionated, easy-to-follow flow.

Getting started: setup & prerequisites

Requirements

• One Trezor device (Model T, Model One, or Trezor Safe series)
• Desktop (Windows/macOS/Linux) or mobile — Trezor Suite supports desktop & web variants
• Latest Trezor Suite build or access to docs.trezor.io for SDKs and docs

Step-by-step

1. Download and verify Trezor Suite — always fetch from the official site and verify signatures when possible.
2. Initialize your device — follow the Suite prompts to create or recover a wallet. This typically takes ~15 minutes for a new device.
3. Enable developer options — for advanced flows you may enable additional logging or developer tools inside the Suite or use testnet configurations.

# example only — replace with official checksum instructions
shasum -a 256 trezor-suite-installer.dmg
# compare against published checksum

Notes about device models

Different Trezor models may have slightly different flows (Model T vs Model One vs Safe devices). When in doubt, check the model-specific docs for initialization and firmware update steps.

Integration patterns

Trezor Connect (browser / third-party integration)

Trezor Connect is the official integration layer that lets web apps communicate with Trezor devices through the Suite or popup flows. Use it for authentication, transaction signing, and retrieval of public keys/addresses.

Basic usage pattern

Typical flow:

1. Load Trezor Connect SDK in your web app.
2. Request the operation (getAddress, signTransaction).
3. Open Suite or a Connect popup to prompt the user.
4. Receive response, handle errors and user rejection gracefully.

import TrezorConnect from '@trezor/connect';

async function getAddress() {
  const response = await TrezorConnect.getAddress({
    path: "m/44'/0'/0'/0/0",
    coin: 'btc',
  });
  if (response.success) {
    console.log('Address:', response.payload.address);
  } else {
    console.error('Error:', response.payload.error);
  }
}

Native & desktop integrations

If you build a desktop application or a daemon, the recommended approach is to rely on the documented Suite APIs or to embed the official Suite as a trusted companion. Avoid rolling your own USB stack for signing — reuse the official libraries when possible to remain up-to-date with device firmware changes.

API examples & snippets

Signing a Bitcoin transaction (high level)

High-level steps for an offline signing workflow:

• Prepare raw transaction without signatures.
• Serialize inputs and outputs and send to device to request signatures.
• Device returns signatures — assemble and broadcast.

# 1. create unsigned tx on your server/app
# 2. call TrezorConnect.signTransaction with serialized inputs
# 3. assemble tx hex and send to network

Handling errors & UX

Always detect and show device states: disconnected, firmware outdated, user rejected, or incompatible model. Offer clear remediation steps inside your UI — point users to firmware update flows or Suite troubleshooting pages.

Security and best practices

Core security principles

Treat the Trezor device as the hardware root of trust. Private keys never leave the device; your code should never attempt to extract seeds or secrets. Use the device to sign operations and validate outputs on-device whenever possible.

Key recommendations

• Always use official SDKs and libraries to interact with Trezor.
• Verify downloads and binaries from official sites.
• Encourage users to confirm transaction details on-device (amounts, addresses).
• Keep your integration up-to-date with Suite & Connect releases.

Privacy considerations

Minimize telemetry and do not log sensitive data. If your app collects analytics, avoid attaching public keys or addresses to user identifiers unless explicitly necessary and consented.

Developer best practices

Version compatibility

Track Suite & Connect versions and perform compatibility checks. Always surface a clear error if a requested API is not supported by the user's device or Suite version.

Testing

Test on real devices and across the models you intend to support. Use testnet environments for signing flows and continuous integration where feasible.

UX

Design flows so users are never surprised: the on-device screen should mirror what the app shows. Use progressive disclosure for advanced developer options and provide safe defaults for users.

Official resources

Below are authoritative Trezor resources you should bookmark; these links point to official documentation, guides and developer portals. Use these as the primary source of truth:

Sample checklist for release

• ✅ Verify you use the latest supported Connect/Suite APIs
• ✅ Test signing flows on real devices
• ✅ Provide clear on-device verification for users
• ✅ Include fallback messaging for unsupported devices
• ✅ Keep direct links to Trezor docs in your support pages

Conclusion

This page is a practical starting point — not a replacement for the official docs. Use the linked official resources for authoritative instructions, security updates, and SDK downloads. When building integrations, default to the official SDKs and never attempt to export secrets from the device.
