Trezor Suite® – Getting Started™ Developer Portal

Welcome to the Trezor Suite® Getting Started™ Developer Portal. This quick guide helps developers onboard to the Trezor Suite® developer ecosystem, explore SDKs, connect to testnets, and learn best practices for integrating hardware wallet support into applications. Whether you're building a browser extension, mobile app, or web wallet, this guide covers the essentials: registration, authentication, sandbox testing, and secure transaction workflows.

Overview

The Trezor Suite® Developer Portal provides APIs, SDKs, and documentation to integrate with Trezor devices and the Trezor Suite client. Use the portal to obtain API keys, download SDKs, and read implementation guides. Key resources include the Trezor Connect library, device protocol references, message signing guides, and best practices for secure handling of user accounts and transaction signatures.

Quick Start — Step by Step

1. Create a Developer Account: Sign up on the Developer Portal and verify your email to access keys and sandbox environments.
2. Get API Keys: Request sandbox API keys for testnet operations. Use these keys in development only; rotate them before going to production.
3. Install SDKs: Install Trezor Connect or the official SDK for your platform. Typical install commands are shown below.

// Javascript (npm)
npm install --save trezor-connect
// or import via CDN for quick prototyping

Important: During development, always use test networks and do not use mainnet keys or real seed phrases. Follow the hardware wallet UX patterns recommended in the portal documentation to ensure user trust and security.

Example: Initialize Trezor Connect (web)

import TrezorConnect from 'trezor-connect';

TrezorConnect.init({
  manifest: {
    email: 'dev@example.com',
    appUrl: 'https://your-app.example'
  }
});

TrezorConnect.getPublicKey({path: "m/44'/0'/0'/0/0"})
  .then(response => console.log(response))
  .catch(err => console.error(err));

Best Practices

• Keep all private keys and recovery seeds only on the device — never transmit or store them on servers.
• Use the latest SDK versions and subscribe to developer portal release notes for security updates.
• Implement clear and transparent UI prompts for every hardware action: show amount, recipient, and fees before asking the user to confirm on-device.
• Adopt rate limiting and key rotation for production API keys.

Sandbox and Testnets

The Developer Portal supplies sandbox endpoints that mimic production but run against testnets. Use these to fully validate signing flows, address discovery, and account restoration before moving to production. Ensure your integration supports simultaneous multiple-account discovery and error handling for device disconnection, firmware mismatches, and user cancellations.

Security Checklist

• Validate firmware version on device and prompt for updates when necessary.
• Never log sensitive payloads — mask and redact addresses and transaction details in logs.
• Use TLS everywhere and certificate pinning for mobile apps where feasible.
• Provide clear recovery instructions and educate users about social engineering risks.

Developer Tools & Debugging

The portal includes diagnostic tools for device connection logs, a sandbox transaction visualizer, and sample apps that demonstrate common integration patterns (send/receive, multi-sig, and account discovery). Use these resources to speed up QA and reduce regressions.

Support & Community

If you run into hardware or integration issues, the Developer Portal lists official support channels, Slack/Discord community links, and a tracker for SDK issues. When reporting bugs, include sanitized logs, SDK version, device model, and firmware revision to help engineers reproduce and resolve issues faster.

Onboarding Checklist (Summary)

1. Register on Developer Portal and confirm email
2. Request sandbox API keys
3. Install SDK and run sample app
4. Test on hardware device using testnet
5. Follow security checklist and move to production

Frequently Asked Questions (FAQ)

1. What is the first step to build with Trezor Suite® Developer Portal?

Create a developer account on the Developer Portal, verify your email, and request sandbox API keys. From there, install the official SDK (like Trezor Connect) and test with a Trezor device on a testnet.

2. Can I use the same API keys in production and sandbox?

No — sandbox keys are for testing only. Generate and rotate production keys for live environments to maintain security and access controls.

3. Do I need physical Trezor hardware to develop?

While some emulators exist, testing on real hardware is strongly recommended to validate user flows, device firmware behavior, and on-device confirmations. Emulators can help early development but cannot replace hardware tests.

4. How should I handle user recovery phrases in my app?

Never collect or transmit recovery phrases. If a user needs to restore an account, instruct them to perform restoration directly on their Trezor device. Provide guidance and UX that makes it clear you never ask for seeds.

5. Where can I get help if I'm stuck?

Use the Developer Portal’s support resources: documentation, community channels, issue tracker, and contact forms. When filing an issue, include SDK version, OS, browser, device model, and firmware to speed up assistance.
