Trezor Suite® – Getting Started™ Developer Portal

Welcome to the official developer quickstart for Trezor Suite® – Getting Started™ Developer Portal. This landing-style guide is designed for engineers, integrators, and technical product owners who want a clean, practical path from zero to a working integration with Trezor Suite. Follow the concrete steps, copy the code snippets, test locally, and bring secure hardware wallet support to your product.

Get started Documentation

Overview

At a high level, the Developer Portal covers three core areas: setup (installing Suite and connecting devices), programmatic access (APIs, event flows, IPC), and security considerations (device policies, user flows, signing). The content below breaks these into clear tasks you can follow today.

Quick setup (developer machine)

1. Install Suite

Download the latest Trezor Suite desktop or web build. Desktop builds provide full local IPC capabilities needed for advanced developer workflows.

Download Suite

2. Connect a device

Use an official Trezor device (Model T or Model One). Connect via USB and follow the on-screen instructions to unlock the device and allow developer access where prompted.

Connect device

3. Test a call

Run the sample helper (provided below) to confirm IPC/websocket communication with Suite and the hardware wallet.

// sample pseudo-code
await connectToSuite();
const accounts = await listAccounts();
console.log(accounts);

Sample code

4. Inspect logs

Enable developer logs in Suite to monitor events, messages, and transport state. This helps when debugging pairing and signing flows.

Programmatic patterns

There are two main patterns: embedded (SDK / library link) and external (IPC or WebUSB) integrations. The embedded approach is easiest for apps that bundle Suite components; the external approach is preferred when isolating security boundaries between the wallet and your application logic.

Example: to trigger a signing operation, your app calls the Suite RPC endpoint with a prepared transaction payload; Suite prompts the user on-device to confirm the transaction and then returns a signed payload. Use request/response correlation IDs and verify the signature on your backend before broadcasting.

Security best practices

Treat the device as the single source of truth for private key operations. Never export seeds or private keys from the device. Use ephemeral session keys between Suite and your application and validate all device responses cryptographically. If your integration stores any account metadata, store only public addresses and non-sensitive metadata; avoid persisting derivation paths that could leak user structure unless encrypted and consented.

Design flows so that sensitive prompts happen on-device (PIN, passphrase entry) and users always inspect critical details (amount, destination address) on the Trezor screen. Resist automatically approving transactions or creating blind signing experiences without explicit user confirmation.

Developer checklist

Use official library releases and pin versions.
Monitor transport library updates for security patches.
Perform end-to-end tests with a cold-start device regularly.

Code example: simple sign flow

// Pseudo-code example
const tx = buildTransaction({to: '0x...', value: '1000000000000000000'});
const req = await suiteApi.requestSign({tx});
const signed = await waitForSignature(req.id);
verifySignature(signed);

FAQs

1. What devices are supported?

Official Trezor Model T and Trezor One are supported. For development, Model T offers the touchscreen and newest firmware features; Model One remains supported for core signing flows.

2. Can I test integrations without a physical device?

Suite includes a simulator mode for basic flows, but hardware-backed signing and PIN/passphrase interactions require a physical device to fully validate UX and security behavior.

3. Where can I find API reference and SDKs?

Visit the central documentation hub via the main link. Official SDKs and release notes are published alongside reference guides and changelogs.

4. How do I handle passphrase-protected accounts?

Passphrase handling must always happen on-device or via secure input collection. Never ask users to provide passphrases to your backend without clear consent and encryption-at-rest.

5. Who do I contact for security disclosures?

Use the official security contact channels listed in the docs. Follow responsible disclosure guidelines and provide reproducible test cases when reporting vulnerabilities.
