Trezor Suite® – Getting Started™ Developer Portal

Overview

Welcome to the Trezor Suite® – Getting Started™ Developer Portal. This page is designed to help developers integrate with the Trezor Suite experience, including connecting a Trezor hardware device to a desktop or web application, interacting with the Suite's public interfaces, and understanding the typical flows for authentication, transaction signing, and state synchronization.

The Trezor Suite environment (Trezor Suite, Trezor/Suite, trezor suite) provides secure, audited device interaction with clear APIs and UX patterns. Use this guide as the first stop when building a Trezor Suite integration or embedding Trezor hardware flows into your product.

Prerequisites

• Basic knowledge of JavaScript/TypeScript and web development.
• A Trezor hardware wallet (Trezor Model T or Trezor One recommended).
• Node.js (LTS) installed for any local development tooling.
• A test network or sandbox environment for signing and broadcasting transactions.

Quickstart — Connect and Sign

The minimal integration flow typically includes: (1) detecting the device, (2) establishing a secure session, (3) requesting device information, and (4) signing a transaction or message. Below is a minimal pseudo-code example to illustrate the flow.

// Pseudo-code: detect + connect + sign
import { connectToTrezor, getDeviceInfo, signTransaction } from 'trezor-suite-sdk';

async function run() {
  const device = await connectToTrezor();
  console.log('Connected to', await getDeviceInfo(device));
  const tx = { /* transaction payload */ };
  const signed = await signTransaction(device, tx);
  console.log('Signed TX', signed);
}

run().catch(console.error);

In production, handle user prompts, device retries, USB/bridge fallbacks, and error states. Test interactions in a controlled environment before broadcasting to mainnet. Remember: the Trezor hardware prompts the user for confirmation on-device for every sensitive action.

Common Integration Tips

1. Respect on-device prompts: Every signing operation requires user approval on the device. Design your UI to clearly instruct users what they'll see on their Trezor.
2. Keep transport resilient: Support WebUSB / Bridge / WebHID flows where applicable. Gracefully handle disconnects and device permissions.
3. Minimal permissions: Request only the minimal information from Trezor Suite or the device required for your flow.
4. Log securely: Avoid logging sensitive payloads. Never log private keys, recovery seeds, or full transaction inputs that reveal secrets.
5. UX consistency: Match the user's expectations from Trezor Suite — security-first, clear confirmations, and transparent transaction details.

The Trezor Suite brand of client (Trezor Suite, Trezor/Suite, trezor suite) has established UI patterns you can mirror to reduce user friction.

Security Considerations

Security is paramount. Always assume hostile network conditions and treat the hardware wallet as the single source of truth for private key operations. Use strong origin checks for web integrations, and ensure local services interacting with the hardware are sandboxed and regularly audited.

When designing your integration, be explicit about how transaction data is prepared and presented to the user. The device will confirm the final details — your role is to ensure users see matching, understandable details both in-app and on-device.

Developer Resources

Use the official SDKs, documentation, and examples to accelerate development. Many common tasks—address discovery, PSBT management, and multisig flows—are covered in sample code. If you need support, check the developer community channels and follow the official update channels for changes to protocols and transports.

Again for clarity: Trezor Suite, Trezor/Suite, trezor suite — include these keywords in your internal search if you are collecting reference materials.
