Welcome to the Trezor Suite® – Getting Started™ Developer Portal. This guide is designed for engineers, integrators, and curious developers who want to build secure, user-friendly applications that interact with Trezor hardware wallets. The Developer Portal centralizes documentation, SDK downloads, API references, and example projects to accelerate development and lower friction when integrating wallet interactions. Whether you are building a desktop wallet, a mobile app, or an embedded service, this portal collects pragmatic guidance, quickstarts, and operational best practices to get you into production quickly.

Begin by creating a developer account and registering an application in the portal. Registration provides you with an application identifier and access tokens that allow sandbox testing against simulated devices. The portal includes a sandbox environment so you can test flows such as device discovery, firmware checks, and signing transactions without risking real funds. It also features a complete changelog, release notes, and migration guides for major API and SDK updates. Make sure to follow developer policies and stay current with the migration guides when upgrading SDK versions. [TREZOR-DEV-KEYWORD]
Explore the SDKs available for multiple platforms: TypeScript for web and Electron apps, Python for scripts and backend services, and Rust for performance-critical or embedded scenarios. Each SDK package includes installation instructions, a quickstart example, and a test suite you can run locally. The TypeScript SDK exposes a high-level API that abstracts USB, WebUSB, and WebHID interactions so you can focus on user flows instead of low-level transport details. The Python SDK is great for server-side signing coordination and offline transaction assembly. The portal documents compatibility, peer dependencies, and canonical usage patterns so you can pick the SDK that best fits your stack. [TREZOR-DEV-KEYWORD]
Security is foundational. Use the portal’s security checklist to implement device attestation, verify firmware integrity, and prompt users for on-device confirmations for sensitive operations. The portal explains the recommended cryptographic flows, including how to derive keys using standard BIP paths for supported cryptocurrencies and how to implement multi-signature setups. Keep private keys off your servers; use Trezor to sign on-device and only transmit signed payloads. The documentation also outlines how to validate device attestation and how to display on-device messages so users can confirm intent. [TREZOR-DEV-KEYWORD]
The Developer Portal includes several example integrations to speed up implementation. Look at a sample Electron wallet that implements account discovery, transaction building, and broadcasting. There is a mobile demo showcasing QR-based transaction transfer and a backend service example that uses the Python SDK to assemble transactions and request signatures via a user-driven flow. Example code snippets demonstrate proper error handling, device reconnection logic, and graceful fallbacks when devices are unplugged or when permission prompts are dismissed. These examples are intentionally small and modular so you can copy, adapt, and extend the pieces that match your product architecture. [TREZOR-DEV-KEYWORD]
Testing and compliance are covered thoroughly. Find unit tests and integration tests for common flows, plus recommended patterns for mocking hardware during CI runs. Compliance notes include guidance on handling personally identifiable information (PII), data retention policies, and GDPR considerations for EU-based services. The portal also points to third-party audit reports and security assessments that validate the implementation recommendations. Follow the portal’s release policy for cryptographic libraries and keep an eye on CVE alerts relevant to dependencies. [TREZOR-DEV-KEYWORD]
Performance and UX matter. The documentation explains best practices for minimizing latency during device interactions, such as batching operations, reducing round trips for signing, and prefetching account metadata. There are sections on crafting clear on-device messages so users can confidently confirm actions, and on designing fallbacks for users with limited connectivity. The portal’s UI kit provides components for status indicators, device prompts, and transaction previews that keep interfaces consistent and accessible. Consider staging UX flows with usability testing to refine wording and reduce user errors. [TREZOR-DEV-KEYWORD]
If you need deeper help, the portal hosts community forums, an issue tracker, and direct support channels for registered developers. Use the forum to search for similar integration questions or to share pull requests for the example projects. The issue tracker allows you to report bugs with reproduction steps. Enterprise customers have additional SLAs and a dedicated support contact for migration and customization assistance. There's also a roadmap section where major planned features and timelines are published so integrators can plan accordingly. [TREZOR-DEV-KEYWORD]
Release management guidance makes updates safe and predictable. Maintain compatibility by following semantic versioning and deprecation notices provided in the portal. Use the sandbox to test migrations before rolling out changes to production. There are scripts to automate firmware checks and to alert users in-app when device firmware requires an update. The portal also includes a step-by-step rollout checklist to minimize disruption during major version changes, and sample automation to send staged feature flags to controlled cohorts.

Finally, make sure to follow the community code of conduct and licensing terms when using or contributing to SDKs. The portal clarifies license types for each SDK and external dependency, and it gives guidance on contributing back improvements. The goal of the Developer Portal is to empower developers to build secure, intuitive, and robust applications that leverage Trezor hardware for strong, user-controlled key management. Build responsibly, prioritize user safety, and avoid designing flows that request or transmit private keys off-device. [TREZOR-DEV-KEYWORD]
