Trezor Suite Developer Portal | Start Your Journey

By Trezor Developer Advocate — Updated:

A practical, hands-on guide for software engineers and integrators who want to build with Trezor: overview, key resources, API touchpoints, and best practices to get productive fast.

Why build with Trezor Suite?

Hardware wallets remain the gold standard for private key security. Trezor's open-source ecosystem — including Trezor Suite, Trezor Connect and firmware repos — lets you integrate secure signing and authentication directly into your apps without exposing users' keys. For developers, this means fewer security tradeoffs and a lean, audited interface for common wallet operations.

Start here: Trezor publishes detailed Suite documentation and developer-focused guides that explain architecture, APIs, and integration patterns. :contentReference[oaicite:1]{index=1}

Core developer building blocks

Trezor Suite documentation (overview)

The Trezor Suite documentation is the canonical starting point for Suite-specific APIs, UI conventions, build scripts and monorepo structure. It explains how the Suite interacts with devices, how to run it locally, and where packages like connect and the Suite frontend live. :contentReference[oaicite:2]{index=2}

Trezor Connect — the bridging SDK

Trezor Connect is the JavaScript-friendly SDK used by countless third-party wallets to perform operations such as retrieving public keys, signing transactions and authenticating users. It exposes a high-level API that opens a secure UI popup and routes operations to a connected Trezor device. If you plan a web or Electron integration, Connect is your primary integration path. :contentReference[oaicite:3]{index=3}

Open source repositories

Trezor and SatoshiLabs maintain active GitHub organizations with Suite, firmware, Connect and tooling repositories. These repos are essential not only for code but for examples, CONTRIBUTING guidelines, and release notes that affect integrations. Exploring the monorepo and linked packages reveals real-world patterns for transaction flows and error handling. :contentReference[oaicite:4]{index=4}

Quickstart checklist (first 20 minutes)

1) Read the Suite docs

Open the Suite docs to understand the repo layout and dev prerequisites (Node, Yarn, Rust toolchain for firmware, etc.).

2) Clone the monorepo

Clone trezor-suite and run the local dev server to see the application in action. This is the fastest way to understand a feature end-to-end.

3) Play with Trezor Connect

Use the Connect explorer and SDK to try basic calls (getPublicKey, signMessage, signTransaction) in a safe environment.

4) Check firmware & security docs

Before shipping a product, read the firmware and security guidelines in the Trezor repos and official disclosure channels. Security recommendations and responsible disclosure practices are documented in the firmware repo.

Best practices for integration

Never manage private keys

Design your app so the Trezor device is always the only place where private keys are present. Use Connect or the Suite API to delegate signing to the device.

Graceful UX for device flows

Account for device prompts, firmware update screens, and user confirmation steps. Provide clear retry and recovery paths if the device disconnects mid-flow.

Versioning & compatibility

Track Connect and Suite versions and test against older firmware when possible. Some UX patterns (popups vs new window flows) may change between versions; follow the official changelogs in the repositories. :contentReference[oaicite:5]{index=5}

10 official links — one-click access

These are curated official resources (docs, repos, guides). Buttons are full-width colored for easy scanning — each opens an official Trezor page or repository.

Sample integration snippet (Trezor Connect)

Use this minimal example as an experiment to open the Connect popup and request a device public key for a BIP44 path. This is for demonstration only — check the latest Connect docs and explorer before production use.

<!-- Include Connect from CDN or npm package -->
<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 getPubKey(){
    const resp = await TrezorConnect.getPublicKey({
      path: "m/44'/0'/0'/0/0",
      coin: "Bitcoin"
    });
    if(resp.success) {
      console.log('Public key:', resp.payload.publicKey);
    } else {
      console.error('Error:', resp.payload.error);
    }
  }
</script>

This snippet assumes Connect v9+ conventions — always confirm the version and parameters in the Connect docs before deploying. :contentReference[oaicite:6]{index=6}

Troubleshooting & community

Common issues

Device not showing up? Check USB permissions, OS drivers, or whether Suite/Connect is in a web context that blocks external popups. Firmware mismatches and deprecated Connect flows are frequent causes of integration breakage.

Reporting bugs & security

When you discover a security issue, follow the private disclosure channels described in the firmware repo and Trezor security docs — do not create public issues for vulnerabilities. :contentReference[oaicite:7]{index=7}

Get involved

Contributions, PRs, and discussions on GitHub help keep the ecosystem healthy. If your product integrates Trezor, consider open-sourcing relevant adapter code and documenting the UX decisions you made for users.
