Why build with Trezor Suite?
Trezor Suite is the official desktop and web application for managing Trezor hardware wallets — offering secure signing, account management, portfolio tracking, and integrations with many chains and tokens. For developers, the Suite ecosystem provides documented tools, SDKs, and integration patterns that let you safely connect your service to users' hardware wallets.
Tip: Always use the official docs and GitHub repo as your primary sources — and verify downloads from the official site before running binaries.
Quick tour: Developer resources (10 official links)
Below are ten authoritative pages that every Suite developer should bookmark. Each link opens in a new tab and uses the official Trezor color for visual emphasis.
Getting started: local dev checklist
1. Clone the monorepo & install
Start from the official monorepo. Follow the README for prerequisites (Node version, yarn, dependencies) and environment variables required for local dev and testing.
2. Choose your integration approach
There are two common approaches:
- Embed Trezor Connect — use the JS SDK to call `getPublicKey`, `signTransaction`, etc., from your web app.
- Contribute to Suite — create UI/UX or backend improvements inside the Suite monorepo and follow contribution guidelines.
3. Security & testnet workflow
Always test on a non-custodial testnet account first. Use only devices and seed phrases dedicated to development and never reuse real recovery seeds for testing.
Example: basic Trezor Connect flow (web)
This example demonstrates how to request a public key from a user's Trezor device using Trezor Connect. In production, always verify manifest and follow latest Connect docs.
// Minimal Trezor Connect example
import TrezorConnect from 'trezor-connect';
TrezorConnect.init({
manifest: { email: 'dev@example.com', appUrl: 'https://your-app.example' }
});
async function getXpub(path){
const response = await TrezorConnect.getPublicKey({ path });
if (response.success) {
console.log('xpub:', response.payload.xpub);
} else {
console.error('error:', response.payload.error);
}
}
Notes
Replace the manifest values and path with your app's values. Consult the Connect docs for full method signatures and advanced flows like coin-specific signing and message signing.
Best practices & integration tips
Security first
Trezor's value comes from hardware isolation — keep private keys off the host, and only request what you need (no over-privileged requests).
UX patterns
Make the hardware interaction obvious to users: show a progress step for "Connect hardware → Confirm on device → Transaction signed" and handle device errors gracefully.
Keep dependencies updated
Track the official docs and repo for breaking changes (Connect API versions, Suite packaging changes, Bridge deprecation, etc.).
Contributing to Suite
If you plan to contribute code, open issues and PRs in the monorepo and follow the contribution guide. Run tests locally and document the changes in a clear, security-minded manner.
Community & support
Use GitHub Issues for technical questions/bugs and look for official announcements on the Trezor site for major changes. Respect the security policy if you find a vulnerability — follow responsible disclosure.
Common pitfalls
Installing untrusted software
Only download Suite and binaries from the official pages or the verified GitHub. Be wary of lookalike sites or unofficial builds.
Bridge vs. Suite
Historically, Trezor Bridge assisted browser integrations; check the official deprecation/upgrade notes before shipping integrations that rely on standalone Bridge binaries.
Next steps — a 30-day learning plan
- Days 1–3: Read the Suite docs and the Connect guide. Clone the monorepo and run the dev environment.
- Days 4–10: Build a tiny demo app that requests an xpub and displays a derived address.
- Days 11–20: Implement transaction signing for a single network (e.g., Bitcoin testnet or Ethereum testnet).
- Days 21–30: Hardening: add error handling, UI flow improvements, tests, and write up integration docs for your team.
