Introduction — Why Trust Matters (H2)

Trust is the foundation of any wallet integration. When building on top of a hardware wallet ecosystem such as Trezor Suite, developers must prioritize secure key handling, transparency, and reproducible builds. This developer portal sample distills the key steps — from installation and pairing to API usage and recommended integration patterns.

Overview — What this guide covers (H3)

This single-page presentation contains:

  • Clear setup steps for both users and integrators.
  • Practical introductions to Trezor Connect and the JavaScript SDK.
  • Best practices for security, UX, and testing.
  • Troubleshooting tips and 10 official Trezor links for deeper reading.

Getting started: Download & Install (H3)

Point your users to the official Trezor Suite download for desktop or to open the web app. Desktop provides the most controlled environment for development and testing, while the web app is useful for quick trials and demos.

Step-by-step setup (H4)

  1. Download Trezor Suite and install it on your development machine.
  2. Connect a Trezor device and follow the on-screen initialization steps (firmware and wallet backup).
  3. Enable developer mode or connect via Trezor Connect for integrations from web apps.

Using Trezor Connect (H4)

Trezor Connect is the standard browser-to-device bridge. It exposes a well-documented API to request signatures, read public keys, and more — without exposing private keys to your app. Use it to keep UX smooth while keeping cryptographic operations fully isolated on the device.

Sample flow (H5)
// Example: basic connect flow (pseudo-JS)
import TrezorConnect from 'trezor-connect';
TrezorConnect.init({manifest:{email:'dev@you.com',appUrl:'https://your.app'}});
const response = await TrezorConnect.getPublicKey({path:"m/44'/0'/0'"});
if(response.success){ console.log(response.payload); } else { console.error(response.error); }

SDKs & packages (H3)

Trezor maintains JavaScript packages and other libraries useful for building integrations. Review package READMEs in the suite monorepo and use the Connect explorer for the latest calls and examples.

Integration patterns (H4)

Recommended approaches:

  • Web apps: Use Trezor Connect and a server-side signing workflow for high-value operations.
  • Desktop apps: Use native Suite or embed the Suite webview for consistent UX.
  • Third-party wallets: Use the documented public APIs and follow versioning & compatibility guidance.

Security & Trust (H3)

Prioritize these principles: least privilege, reproducible builds, hardware-only signing, and clear user prompts. Never send private keys to remote services or logs.

User experience for secure flows (H4)

Helpful UX patterns: concise confirmation text, explicit transaction details (amount, fees, recipient), and clear warnings for unknown requests.

Testing and QA (H3)

Test on real hardware frequently. Use release notes & changelogs to track breaking changes. Add automated tests that mock the Connect responses where possible and keep an extra manual-testing checklist for firmware interactions.

Troubleshooting (H3)

Common problems:

  • Device not recognized — check cable, USB permissions, and firmware update status.
  • Connect initialization errors — verify manifest details and CORS settings on embedding origin.
  • Unexpected firmware prompts — follow official recovery/firmware steps as documented.

Conclusion — Shipping with confidence (H3)

Integrating with Trezor Suite gives your product access to a hardened signing environment. Follow official docs, validate every release against the Suite updates, and use the links in the resources to stay current.
