Overview
Trezor Suite is the official desktop and web companion for Trezor hardware wallets. The Developer Portal surfaces the tools and documentation you need to integrate Trezor interactions safely into your applications. This presentation covers the essentials: architecture, getting started, common tasks, testing, and a helpful FAQ for developers.
Getting started
Prerequisites
- Familiarity with JavaScript/TypeScript and modern web tooling.
- A Trezor device (Model T or One) and the latest firmware.
- Node.js installed for local dev tools and examples.
Quick start — connect to Trezor Suite
Follow these steps to open a secure connection from your app to the Trezor Suite or Trezor Bridge:
// Pseudocode
const transport = await TrezorConnect.transport();
const res = await TrezorConnect.getAccountInfo({path:"m/44'/0'/0'/0/0"});
if(res.success) console.log(res.payload.address);
This snippet demonstrates the typical flow: open transport, request data, handle the response and errors. Production code should implement robust error handling and user-friendly device prompts.
Architecture & components
Key building blocks
- Trezor Suite — UI and app flows for end-users.
- Trezor Bridge — native bridge to talk with the device from browsers.
- Trezor Connect — a JavaScript library that exposes signing and read-only device commands.
- Firmware — device-level crypto operations; always verify firmware compatibility.
Security model
Design with the assumption the device is the root of trust. Keep all private keys inside the Trezor device — use the hardware signing endpoints and never export seed phrases programmatically.
Best practices for developers
- Always show clear, localized prompts when asking users to confirm actions on-device.
- Use deterministic paths and clearly document them for users and support teams.
- Keep dependencies minimal — avoid bundling unnecessary crypto code that duplicates device capabilities.
- Test across firmware versions and on both Trezor Model T and One.
- Follow secure upgrade guidance when exposing firmware update flows to users.
Testing & CI
Automated tests should mock the device responses for unit tests and use a small set of manual integration tests with physical devices in your CI pipeline where possible. Use dedicated testnets for signing and broadcasting transactions.
// Example CI step (concept) - run: npm test -- --integration - run: node ./scripts/manual-device-check.js
FAQ
Q: What is the difference between Trezor Suite and Trezor Connect?
A: Trezor Suite is the official app with UI for end-users; Trezor Connect is a developer-facing JS library that allows third-party apps to interact programmatically with a Trezor device.
Q: Can I get users' private keys programmatically?
A: No. Private keys and seeds never leave the device. Use signing methods exposed by the device API instead.
Q: Which networks are supported?
A: The device supports a wide set of chains — consult the official docs for a current list. Test on testnets before production.
Q: Where can I find official documentation and support?
A: The Developer Portal, the official Trezor docs and the Suite repository are the best starting points (links in the right column).
