Trezor Suite® – Getting Started™ Developer Portal

Overview – Why use Trezor Suite for developer integration?

The Trezor Suite Developer Portal is your official hub for building custom integrations with the powerful Trezor API and SDK. Whether you're developing a web app, desktop wallet or enterprise custody solution, Trezor Suite gives you secure hardware wallet integration with full control and transparency.

By using Trezor Suite you benefit from: hardware-backed private key isolation, open-source SDKs, comprehensive documentation, and deep developer support. The Developer Portal focuses on how to get up and running fast, implement secure signing flows, and build robust integrations.

Quick Start – 3 Steps to a working integration

Step 1: Connect the Device

Install the Trezor Bridge or enable WebUSB in your browser for direct hardware connectivity. Ensure your Trezor device firmware and Suite version are current before continuing.

Step 2: Authenticate & Sign

Use the SDK to request a public key or sign a transaction, with user confirmation on the hardware device. The flow will look like:

const result = await TrezorConnect.getPublicKey({ path: "m/44'/0'/0'/0/0" });
if (result.success) {
  // use result.payload.publicKey
}

Always verify confirmation on the device screen.

Step 3: Integrate & Verify

Integrate the responses into your application logic: verify the signed transaction, handle error codes, and present a friendly UI. You should treat the hardware device as your root of trust and never store raw seeds in your app.

Core Concepts – Secure Key Management & Hardware Wallet Integration

Understanding key concepts is vital for building a safe integration:

Hardware-backed keys: With Trezor Suite your private keys are securely stored on the device and never exposed to your host application.
Deterministic derivation: The Trezor API uses established standards (BIP-32/BIP-39/BIP-44) for predictable wallet paths and integration flows.
Fail-safe UX: Build flows that handle hardware disconnects, user cancellations, firmware updates and errors gracefully.
Telemetry & privacy: Collect minimal telemetry, respect user opt-outs, and never transmit any sensitive material (seeds, passphrases, private keys).

Best Practices – Production-ready Developer Integration

To deliver a high quality integration with Trezor Suite, follow these recommended practices:

Pin firmware verification: In your CI pipeline, verify that the firmware your users install is signed and genuine.
Staged roll-outs: For signing flows, use feature flags and gradual roll-outs to test impact before broad release.
Clear error mapping: Map hardware error codes to meaningful UI messages so users understand what to do next.
Separate UI and hardware logic: Keep your user interface distinct from the hardware logic so you can update flows without risking key-handling code.
Secure backups: Use and recommend secure seed backup workflows, offline storage, and physical media (such as steel plates) for critical flows.

By applying these best practices, your integration with Trezor Suite will be robust, user-friendly, and secure. Keyword: Trezor Suite Developer Portal, Trezor API integration, hardware wallet flow.

Frequently Asked Questions (FAQs)

Q1: What do I need to start using the Trezor API?

You need to install the Trezor Bridge (for desktop) or enable WebUSB in your browser, include the official SDK in your project, connect your Trezor device and follow the quick-start steps. The Developer Portal provides sample code and full documentation.

Q2: Is the Trezor Suite Developer Portal free to use?

Yes – the Developer Portal is freely accessible and contains documentation, sample code, SDK references and best practices for integration with Trezor Suite and the Trezor API. Check license terms for redistribution of SDK components.

Q3: Can I test signing flows without risking real funds?

Absolutely. Use testnets, disposable accounts and the Trezor device in demo or low-value mode to validate your integration. Never expose real seeds in a test environment.

Q4: How do I report issues or request new features for the Developer Portal?

You can open issues or feature requests via the official Trezor Suite SDK repository (on GitHub) or contact the Developer Relations team through the official support channels listed in the portal footer.

Q5: What security practices should I follow when building with Trezor Suite?

Key practices include: never store raw seeds in your application; verify firmware authenticity; prompt user confirmation on the device for every signing operation; handle hardware disconnects and cancellations; use strong PINs and optional passphrases; backup seeds off-line and preferably physically. These practices align with the Trezor Suite security model.
