Trezor Suite® – Getting Started™ Developer Portal — Trust & Integration
A practical, developer-first walkthrough to integrate, develop and test with Trezor Suite and Trezor devices. Includes links to official resources and recommended best practices.
Introduction — Why trust matters for developer integrations
Trezor hardware wallets put users in control of private keys; as a developer integrating with Trezor Suite or Trezor devices, your top priorities are preserving that control, minimizing your attack surface, and providing a smooth user experience. This portal-style presentation walks you through the lifecycle: discover, integrate, test, secure, and ship. It’s written for engineers and technical product owners who need practical steps, code hints, and authoritative links.
What you'll achieve
By the end of this guide you'll be prepared to:
- Understand what Trezor Suite provides and where your integration sits in the stack.
- Use Trezor Connect and Trezor Suite APIs to request keys and sign operations securely.
- Follow best practices for verification, signing, firmware compat and user flows.
- Access the official documentation, GitHub repos and developer support channels.
Getting started — quick path to a working integration
1. Prepare your environment
Install the Trezor Suite app for desktop or use the web version during initial testing. Confirm the latest Suite release and verify downloads via signatures. Keep firmware and Suite releases updated during development to avoid incompatibilities.
Tools & accounts
- Developer machine: Linux / macOS / Windows with Node.js (recommended LTS).
- Git and a GitHub account to clone the official repositories for reference and examples.
- A test Trezor device (Model T, Model One, or the new Safe family) and a controlled test wallet for signing exercises.
Pro tip
Use a separate test account and test device. Never use production secrets during development or debugging sessions.
2. Learn the integration surface
The main integration surfaces are: Trezor Connect (JavaScript/Browser bridge), the Trezor Suite APIs, and direct interaction with the device via official libraries in the monorepo. Read the Suite docs and connect docs to learn available features and flows.
Common flows
- Requesting public keys / xpub for watch-only wallets.
- Signing transactions (BTC, ETH, and other supported chains) — using recommended HD derivation.
- Authentication & challenge-response for logins using the device.
Security reminder
All signing should occur on-device; never export private keys from the device. Use the official libraries to ensure your integration benefits from firmware-level protections.
Quick example — request a public key (Trezor Connect)
The code below demonstrates a minimal browser flow using Trezor Connect. This is intended as a starting point — consult the official Connect docs for more advanced options.
// Example: request public key (simplified)
TrezorConnect.getPublicKey({
path: "m/44'/0'/0'/0/0",
coin: "Bitcoin"
}).then(response => {
if (response.success) {
console.log("Public key:", response.payload.xpub);
} else {
console.error("Trezor error:", response.payload.error);
}
});
Notes
Use the official NPM package or include the hosted script as recommended in the Connect docs. Error handling and user prompts are critical — ensure the UI guides users to approve actions on the device.
Best practices — maintaining user trust
Verification & distribution
Always verify Suite installers and release artifacts using the published signatures. For browser-based integrations, prefer the hosted Connect bundles or your own signed assets served over HTTPS with strong CSP headers.
UX design for trust
Display clear device prompts, expected addresses, and transaction details. Make it obvious when a user is being asked to sign a high-value transaction. Never obfuscate the details of a signature request.
Testing
Test across multiple Suite versions and device firmware releases. Use both automated tests (where possible) and manual acceptance testing on a physical device.
Incident response
Prepare procedures to revoke or mitigate faulty releases. Keep communication channels open with Trezor support and the community for coordinated responses to vulnerabilities or UX regressions.
Official resources — 10 authoritative links
Below are direct links to the official Trezor pages, documentation, and repositories that developers should bookmark.
Tip: Bookmark these links and subscribe to release notes for Suite and firmware to keep integrations stable.
Closing — ship with confidence
Integrating with Trezor Suite and devices is a high-value capability: it enables your users to manage and secure crypto natively. Focus on secure request flows, validate user-visible transaction details, use official libraries, and rely on the Suite & firmware release channels to stay compatible.
Checklist before shipping
- Verify downloads and signatures for any Suite or Connect bundles you rely on.
- Run integration tests with multiple firmware versions and device types.
- Provide clear UI language and device-provenance guidance for users.
- Prepare rollbacks and a communication plan in case of urgent fixes.
