Trezor Suite® Developer Portal: Unlock Secure **Hardware Wallet** Integration.

Access the official **Trezor API**, comprehensive documentation, and robust **open-source** tools to build the next generation of **non-custodial** applications.

**Security** and Trust: The Foundation of Every **Trezor** Integration.

The **Trezor Suite** acts as the definitive interface for the **Trezor hardware wallet**. Integrating with our platform means inheriting a decade of proven **cryptocurrency security** expertise. We provide a seamless, audited gateway for applications to request transaction signing without ever exposing the user's **private key** or **recovery seed**. Our commitment to **open-source** development ensures transparency, which is vital for maintaining developer and user trust in the **Web3** space. Integrate with us to assure your **user base** that their digital assets are protected by the highest standard of cold storage technology and the latest **Trezor firmware**.


Your Path to **Trezor API** Mastery and Fast Integration.

A. Trezor Connect (Web Integration)

The fastest route for **dApp** and **exchange** integration. This lightweight **JavaScript library** handles all communication with the device and the **Trezor Suite** background process, ensuring secure, multi-platform operation. Includes support for **Ethereum** and **ERC-20** tokens.

See **Trezor Connect** Docs

B. Trezor Python Library (Backend/CLI)

Ideal for developers building **backend services**, advanced scripting, or custom desktop utilities. Provides deeper control over **Trezor** device operations, including signing complex **Bitcoin** transactions and low-level communication for enterprise integration.

**Indexing** and **Compliance**: Building for Speed and Trust

To achieve rapid **indexing** on search engines like **Microsoft Bing**, developers must focus on high-quality, non-stuffed content and strong semantic HTML. Ensure all documentation and code examples are clear, original, and use technical terminology accurately.

**SEO Note for Bing:** Utilize **IndexNow** and submit your sitemap via **Bing Webmaster Tools**. Bing prioritizes sites with high quality, authoritative, and fresh developer **documentation**. Avoid generic "keyword stuffing" by naturally integrating terms like **Trezor Suite**, **API**, and **hardware wallet** into headings and descriptive text, providing *real value*.

The **Open-Source** Community: Support & Contribution

The success of the **Trezor** ecosystem depends on our developers. All core libraries and **firmware** are fully **open-source** (MIT/GPL licensed). Engage with the **Trezor Developer Forum** for direct technical support. We encourage you to contribute to our GitHub repositories, report vulnerabilities through our **Bug Bounty** program, and help shape the future of **hardware wallet** interaction. Access the latest **Trezor** **API documentation** and **changelogs** here.


Frequently Asked Questions (FAQs)

Yes, the primary **Trezor Connect** and all associated client-side libraries are completely **open-source** and free for all developers to use in their applications. Our goal is to promote widespread **hardware wallet** security.

The **private key** never leaves the **Trezor hardware wallet** device. The **Trezor Suite** or **Trezor Connect** only relays the unsigned transaction to the device for signature, which must be physically confirmed by the **user** on the device display.

Our tools natively support **Bitcoin**, **Ethereum**, **ERC-20** tokens, and a wide array of other **cryptocurrencies**. The official **API documentation** provides a full, up-to-date list of supported **Trezor firmware** assets and new coin integrations.

You can use the **Trezor Emulator** for most integration and testing phases. However, a physical **Trezor hardware wallet** is always required for final production-level testing and security assurance.

After successful integration, submit your application for review to the **Trezor Partner Team**. Compliance with all **security** best practices and a positive **user experience** are key requirements for certification.
