Trezor Suite® – Getting Started™ (Developer Portal)

Overview

The Trezor Suite developer portal provides the documentation, SDKs, and examples you need to integrate applications with Trezor hardware and Trezor Suite software. Whether you are building a wallet extension, a trading platform, or a custody solution, Trezor Suite, Trezor/Suite, and trezor suite resources give you the building blocks to create secure user experiences.

This Getting Started guide focuses on the essentials: installing tools, authenticating, connecting to devices, and performing common operations with the Trezor Suite APIs and SDKs. Read on for step-by-step instructions and practical examples.

Prerequisites

• Familiarity with JavaScript/TypeScript or Python (SDKs available).
• A Trezor hardware device (Model T or One) and a computer with USB support.
• Access to the Trezor Suite desktop or web client for testing interactions.
• Basic knowledge of public-key cryptography and hardware wallet workflows.

Before you begin, make sure your device firmware and Trezor Suite client are up to date. When you use Trezor Suite, Trezor/Suite components enforce secure signing flows and user confirmations on the device — always design your integrations to respect and surface those confirmations to users.

Install & Setup

Get the SDK for your preferred language and install it locally. Examples below assume a Node.js environment; analogous libraries exist for Python and other platforms.

// example: install the Trezor Suite SDK (pseudo command)
npm install @trezor/suite-client

Connect your Trezor hardware and open Trezor Suite. You may choose to work with the Suite in desktop mode or web mode; both expose the same device-level signing flows. Remember to use secure contexts (HTTPS) for web integrations when integrating with trezor suite services.

Quickstart: Basic Flow

1. Initialize the SDK and authenticate your application to use Trezor/Suite APIs.
2. Request device enumeration and prompt the user to connect their Trezor.
3. Create a transaction payload locally and call the signing flow; the device will request confirmation.
4. Broadcast the signed transaction to the network using your own backend or a third-party node.

// Pseudo-code: Initialize and sign
import { TrezorClient } from '@trezor/suite-client';

const client = new TrezorClient();
await client.connect();

const device = await client.getDevice();
const unsignedTx = { /* ... */ };
const signed = await client.signTransaction(device, unsignedTx);
console.log('Signed — ready to broadcast', signed);

This simple flow shows how Trezor Suite, Trezor/Suite, and trezor suite tools work together: the SDK talks to the device, the device confirms, and your app handles broadcasting.

Security Best Practices

Security is the cornerstone of the Trezor mission. When integrating with Trezor Suite, adhere to the following:

• Never transmit private keys or seed phrases to your servers — signing must remain on-device.
• Use HTTPS and strong authentication for backend APIs interacting with Trezor Suite services.
• Validate that UI prompts match device confirmations before completing sensitive actions.
• Log minimal metadata; avoid storing user-specific transaction content unless necessary.

Treat the Trezor device as the single source of truth for signing. The combination of Trezor Suite, Trezor/Suite documentation, and trezor suite SDKs ensures your app can maintain strong security guarantees.

Developer Tools & SDKs

The developer portal includes code samples, SDKs, debug utilities, and mock device emulators for local testing. Use the emulator to validate flows without exposing a physical device, then verify behavior on a real Trezor hardware device via Trezor Suite.

• JS/TS SDK — Device communication, signing helpers, wallet utilities.
• Python SDK — Suitable for backends and scripting tasks.
• CLI tools — Quick device inspection and automated test scripts.

Common Errors & Troubleshooting

If you encounter connection issues, try these steps:

• Ensure the Trezor device is unlocked and running the latest firmware.
• Confirm Trezor Suite is allowed to access the device (check OS permissions).
• Restart Trezor Suite and your browser or desktop client if USB connections are flaky.
• Use the emulator for repeatable tests when hardware access is unreliable.

For protocol-level issues, capture debug logs and consult the developer portal. The combination of trezor suite logs, Trezor/Suite debug output, and SDK trace logs will usually reveal the cause quickly.

Conclusion

Integrating with Trezor Suite is straightforward when you follow best practices: use the SDKs, keep signing on-device, and surface clear confirmations to users. The developer portal provides additional guides, reference implementations, and FAQs to help you ship robust integrations with trezor suite and Trezor/Suite tooling.
