Trust — Trezor Suite® Getting Started™ — Developer Portal

A concise developer-facing guide: integrate, test, and ship with Trezor Suite and Trezor Connect

Getting Started — Overview (h2)

Why Trust Matters (h3)

Trezor emphasizes trustless, auditable, open-source security. For developers that means you can inspect firmware, client code, and Suite integrations, which is crucial when building wallets, dApps, or services that hold user funds.

Quick setup checklist (h3)

  • Download and verify Trezor Suite (desktop or web) and connect your device.
  • Read Trezor Suite developer documentation and the Trezor Connect API references.
  • Work in a testnet or use delegated signing flows for integration tests.

Initial steps for developers (h4)

Start by creating a test flow: install Suite, open the Developer section, and experiment with Trezor Connect demo pages. Use the official docs and example code (below) to wire Connect into your app.

Minimal Trezor Connect example (h4)

<!-- Trezor Connect quick init (cdn) -->
<script src="https://connect.trezor.io/9/trezor-connect.js"></script>
<script>
TrezorConnect.init({ manifest: { email: 'dev@example.com', appUrl: 'https://your.app' }});
async function getPublicKey(){ 
  const resp = await TrezorConnect.getPublicKey({ path: "m/44'/0'/0'", coin: 'btc' });
  console.log(resp);
}
</script>
Notes on example (h5)

Always use the latest Connect release for security and follow the docs to choose the right `manifest` and `path` values.

Integration tips (h3)

Prefer the hosted Connect build for quick testing; for production, pin the version you trust and audit changes when you upgrade. Use the Suite docs and firmware docs as the canonical references for compatibility and supported coins.

Documentation structure (h3)

Official docs are organized into Suite (frontend/integration), Firmware (device internals), and Connect (API). When building an integration, consult Suite docs for UX patterns, Connect docs for API payloads, and Firmware docs for signing formats and path derivation.

Testing & CI (h4)

For CI, mock sign flows or use headless `trezorctl`. Keep secrets out of CI logs — signing must occur on hardware in integration tests where possible. Version pin firmware and Suite dependencies to protect reproducibility.

UX & Onboarding (h4)

Match Suite’s onboarding expectations: users must verify device authenticity and complete device setup. If your app requests signing, clearly show what the user signs and why — transparency builds trust.

Example: signing flow UX (h5)

1) Present the transaction summary. 2) Call Connect to create a signing request. 3) Wait for device presence and user confirmation. 4) Validate response and show final result.

Trezor Connect API — essentials (h2)

Connect exposes methods like `getPublicKey`, `signTransaction`, `ethereumSignTransaction`, and `ethereumSignMessage`. Each method has specific parameters and coin-specific signing logic — rely on official docs for exact schemas.

Best practices (h3)

// Example: simplified getPublicKey using async/await
const resp = await TrezorConnect.getPublicKey({ path: "m/44'/0'/0'" });
if(resp.success) {
  console.log('xpub:', resp.payload.xpub);
} else {
  console.error('Error', resp.payload.error);
}

Security & Trust — policies (h2)

Open-source + Auditable (h3)

Trezor’s code and firmware repositories are public on GitHub; changes are auditable and community-reviewed. Use official GitHub forks/releases for reproducibility.

Supply chain and purchase safety (h4)

Purchase only from official channels. Inspect packaging and firmware signatures, and verify the Suite download checksum when required. If in doubt, contact official support.

Responsible disclosure (h5)

If you discover a security issue, follow the project's responsible disclosure guidelines (usually via security contact on the repo or vendor support) rather than public disclosure.
