Welcome to the Trezor Suite Developer Portal. This guide helps you onboard quickly, shows key integration points, and points to reference docs, SDKs, and support channels. Build secure wallet integrations, hardware-backed signing, and custom tooling—fast.
These steps get you from prototype to production in a matter of days for many common wallet flows—account discovery, transaction signing, and multi-account management.
Trezor Suite exposes several integration surfaces to accommodate native apps, browser extensions, and server-assisted flows. Typical integration points are device communication, message signing, and transaction serialization.
Use WebUSB for browser-native flows, or the Trezor Bridge for broader compatibility. Ensure you handle device permissions and timeouts gracefully. Read the security notes in the official docs before attempting production integration.
Signature flows follow deterministic formats; always confirm the signing details on-device. Validate the addresses and amounts in your UI, and mirror device prompts so users can verify before confirming on the Trezor device.
For more technical details, check Technical Docs and the Developer Repositories.
Below is a minimal example that demonstrates connecting to a Trezor device and requesting public key information.
import TrezorConnect from 'trezor-connect';
TrezorConnect.init({
manifest: {email: 'dev@example.com', appUrl: 'https://your.app'}
});
TrezorConnect.getPublicKey({path: "m/44'/0'/0'/0/0"})
.then(response => console.log(response))
.catch(err => console.error(err));
See the full API reference at the official Docs.
Security is central. The following list describes recommended practices when integrating Trezor Suite:
Users interact with their Trezor device for confirmations. Keep flows simple: display the exact transaction summary your app will send and provide clear fallback/error messaging. If the device is disconnected, provide steps to reconnect and recover gracefully.
Ensure your interface is navigable with keyboard only and supports screen readers—many users with assistive tech rely on clear, text-first transaction descriptions.
When releasing integrations, ensure your CI runs linting, builds, and security scans. Keep dependency versions pinned and maintain changelogs so customers can track compatibility with Trezor firmware and Suite releases.
Provide clear migration guides when you change derivation schemes or supported networks. Link to official channels for breaking changes: Trezor Blog.
Curated resources to help you accelerate development:
Engage with other developers, report issues, and find community-maintained samples. Use GitHub issues for repo-specific bugs and contact support for account or enterprise inquiries.
Community channels include forums, Discord, and the official support portal: Support Center.
Trezor maintains JavaScript and Python libraries; community SDKs exist for other languages. Official repos live on GitHub.
Firmware verification steps are documented on the firmware page. Always verify checksums and release signatures before trusting a device.
Yes. Use WebBluetooth or Bridge-compatible approaches and follow the mobile integration notes in the docs.
Gracefully surface device errors, provide clear reconnect instructions, and avoid exposing cryptographic internals to users.
Report security issues through the official Trezor security contact channels listed on the security page.
