Overview
This document (presentation) is written for developers and technical product owners who want to integrate, extend, or simply understand Trezor Suite® and the Developer Portal. It blends clear steps, best practices, and links to official materials so you can move from first connection to a working integration quickly. The content below uses an organized heading hierarchy (h1–h5) so you can copy-paste it directly into documentation, a website, or a slide deck.
What you will learn
- How to get Trezor Suite running (desktop, web, mobile)
- Developer-specific tools: Connect, SDKs, and the Suite monorepo
- Security and trust principles for hardware wallet integrations
- Testing, packaging, and shipping a developer-friendly integration
Quick start & setup
Step 1 — Prepare your hardware
Unbox and inspect
Confirm device integrity. Treat your Trezor hardware as the root of your trust model: if the physical seal is broken or the packaging looks tampered, stop and contact official support.
Checklist
- Device model correctness (Model One / Model T / other)
- Original packaging and tamper-evidence
- USB cable and adapter if needed
Step 2 — Install Trezor Suite
Use official installers for your platform and verify signatures if you require supply-chain safety. The Suite is available as desktop and web apps—desktop is recommended during development for stability and local debugging.
- Double-click the downloaded installer and follow the OS installer prompts.
- On Linux, use the provided AppImage or package instructions documented in the official repo.
Step 3 — First run & device setup
Follow the guided onboarding: initialize a new wallet or restore from a recovery seed. Take extreme care with recovery phrases—never enter them on a remote or web page not officially provided by the vendor.
Developer tools & ecosystem
The Trezor developer ecosystem includes Connect (browser SDK), libraries in multiple languages, the trezor-suite monorepo, and API docs. Use the documentation and GitHub to explore examples and tests.
Key components
1. Trezor Connect
Browser SDK enabling dApps and web pages to communicate with the Trezor device using a secure channel. Provides user-friendly popups and a consistent UX across integrations.
2. Trezor Suite monorepo
Open-source application that contains the Suite UI, Connect, and platform utilities. Clone the repo to explore how functionality is implemented and to run local dev builds.
3. Documentation site
The technical docs provide package-level references, guides for contributors, and developer-focused pages with code examples and testing instructions.
Security & trust: essential principles
Security is central. The hardware wallet acts as the ultimate root-of-trust for private keys. Integrations must preserve this trust model and never ask users to reveal secrets externally. A few core rules:
- Never transmit recovery seeds over the network.
- Validate firmware versions and provide clear upgrade paths.
- Use official SDKs and signed installers to reduce supply-chain risk.
- Expose only minimal surface area in your integration; rely on the device for signing and key storage.
Best practices for UX & safety
- Provide step-by-step onboarding inside your app with clear callouts when a physical device action is required.
- Use transaction previews, human-readable amounts, and origin metadata so users can verify intent on-device.
- Implement robust error handling for timeouts and device disconnects.
Testing & CI
Automated tests and CI are critical. Use the monorepo tests and join example suites to exercise Connect flows, including simulated device responses where possible. When tests touch physical devices, isolate them as integration tests.
Local development tips
- Run the Suite in dev mode to see logs and network layer activity.
- Mock the device when iterating on UI to speed development cycles.
- Respect rate limits and use test accounts/networks when possible (e.g., testnets for blockchain interactions).
Packaging & deployment
Ship your integration using secure channels, sign release artifacts, and keep users informed about supported versions. Provide a clear rollback and migration plan for breaking changes in SDKs or the Suite.
Troubleshooting common issues
Device not detected
- Check cable & port, try a different USB port or cable.
- On Linux, verify udev rules or required permissions.
- Confirm the Suite version and Connect compatibility.
Transaction signing failed
- Confirm the device firmware is up to date.
- Verify address and amount on the device before signing.
- Check if the blockchain network requires additional fields (e.g., gas limit, nonce).
Conclusion
Integrating with Trezor Suite® means working with a mature, security-first ecosystem. By following the setup, using the official developer tools, and keeping the user’s trust model intact, you can offer seamless and safe hardware-wallet-backed experiences.
