Welcome to the Trezor Suite Developer Portal getting-started guide. This post focuses on practical steps, recommended workflows, and quick code snippets to help you integrate securely with Trezor Suite, develop apps that interact with hardware wallets, and follow best practices for onboarding your users.
Why the Developer Portal matters
Hardware wallet integrations require careful attention to security, user experience, and compatibility. The Developer Portal centralizes official documentation, SDKs, sample apps, and API references so teams can iterate safely and ship predictable integrations for end users. Below are the core areas to focus on when starting.
Core elements you'll use
- SDKs & Client Libraries — official libraries to talk to Trezor devices and Suite.
- API Reference — endpoints, payload formats, and expected responses.
- Sample Apps — real examples showcasing UX flows and error handling.
- Security Guidance — threat models, signing flows, and user prompts.
Quick start: recommended workflow
Step 1 — Explore the official links
Start by bookmarking the official developer resources below to keep a consistent reference while you build.
Step 2 — Install libraries & run sample app
The fastest way to experiment is to clone an official sample repo (see GitHub links above), install dependencies, and run locally. Always run sample apps in a secure environment and avoid exposing private keys.
Example (Node + Trezor Connect)
npm init -y
npm install trezor-connect
node -e "const Connect = require('trezor-connect').default; Connect.manifest({email:'dev@example.com', appUrl:'https://example.com'}); console.log('Ready');"
Design patterns & UX recommendations
When integrating hardware wallet flows into your app, prioritize clarity and predictability:
Keep prompts explicit
Show clear instructions before asking the user to confirm an action on their Trezor device. Include the network, transaction amount, and destination address. This reduces accidental approvals.
Handle device states
Common device states include locked, unverified firmware, or missing trusted host permissions. Provide step-by-step recovery paths and helpful in-app links back to the Developer Portal or Support pages (use the official links above).
Example error pattern
try {
const resp = await Connect.getPublicKey({path:"m/44'/0'/0'/0/0"});
if (!resp.success) throw new Error(resp.payload.error);
} catch (err) {
// Show actionable resolution with link to support
showAlert("Connection failed. Ensure your device is unlocked and Trezor Bridge is running.", "https://trezor.io/support");
}
Security best practices
Security is the raison d'être for hardware wallets. Respect these principles:
- Never request or log users' seed phrases.
- Validate addresses both client- and device-side where possible.
- Keep dependencies up to date and pin versions in CI.
- Show users a link to official support/documentation rather than embedding long instructions in your own site to avoid stale guidance.
Testing & CI
Automate integration tests focused on the communication layer, mocked devices, and user flows. For hardware-in-the-loop testing, label devices used for tests and maintain audit records for firmware versions and device states.
Staging environment checklist
- Use testnet networks where possible to avoid real fund risk.
- Test UX flows with locked / unlocked device states.
- Document every environment variable and dependency for reproducibility.
Common pitfalls and how to avoid them
Assuming universal device availability
Not every user has the same model or firmware. Detect capabilities dynamically and offer fallbacks. Retrieve device features before enabling advanced flows.
Overly verbose instructions
Long-winded prompts tend to confuse users under time pressure. Use concise, step-based instructions and link to the Developer Portal or Support for deep dives (see the "Official links" above).
Wrapping up
The Trezor Suite Developer Portal is a living repository of tools and docs to help you build secure, well-crafted integrations. Bookmark the links above, start with sample apps, and follow the security guidance to protect your users.
