Welcome. This developer portal landing page condenses the essentials you need to get started with Trezor Suite integrations: connectivity (WebUSB, Bridge, WebBluetooth), SDKs, signing patterns, security checks, UX guidance, and release practices. Links below point to official docs and example repos so you can prototype quickly and securely.
At a glance
Trezor devices provide hardware-backed private key storage for robust signing. The recommended integration flow is: connect device → discover accounts → construct transaction → request signature (on-device) → verify and broadcast. The components you’ll interact with are the device transport (WebUSB/Bridge), the client SDK (trezor-connect or language bindings), and your app UI that mirrors device prompts.
- Transports
WebUSB, Bridge, and WebBluetooth for cross-platform compatibility. - SDKs
Official JavaScript, Python bindings; community SDKs available. - Security
Firmware verification, tamper checks, signing policies. - Support
GitHub, community forums, enterprise contact channels.
Getting started — practical steps
- Read the official docs at Trezor Docs.
- Install Trezor Bridge or use WebUSB for direct browser access.
- Clone example repositories from trezor-suite on GitHub.
- Verify firmware and device authenticity on the Firmware page.
- Build a UI that mirrors device prompts and verifies addresses/amounts in a text-first layout.
- Join the community via Support & Community for help and examples.
These steps will let you prototype a signing flow quickly: discover an xpub, construct a transaction, request a signature, and verify the signed payload before broadcasting.
Integration surfaces & best practices
There are three core surfaces to design for: transport layer, signing API contract, and user verification UX. Treat each as a distinct responsibility and test failures in isolation: transport errors (permission/timeouts), API errors (request/response formats), and UX errors (mismatched values).
Transport
Prefer WebUSB for modern browsers and Bridge for broader OS compatibility. For mobile, see the mobile-specific notes in the docs and consider WebBluetooth or a Bridge-based approach. Always implement graceful reconnect and retry flows.
Signing and verification
Construct canonical, human-readable summaries of transactions in your UI. Mirror the fields that the device will show to the user so they can validate on-device. Never assume the device displays all context; always let users verify addresses, amounts, and fees before signing.
Minimal JavaScript example
Use trezor-connect for quick browser integrations. Below is a minimal snippet showing initialization and a public-key request. Replace manifest values before production.
import TrezorConnect from 'trezor-connect';
TrezorConnect.init({
manifest: { email: 'dev@yourapp.com', appUrl: 'https://your.app' }
});
TrezorConnect.getPublicKey({ path: "m/44'/0'/0'/0/0" })
.then(response => console.log('pubkey', response))
.catch(err => console.error(err));

Security checklist
- Verify firmware checksums and signed releases before trusting device state. (Firmware)
- Never log seed phrases, private keys, or raw seed material. Mask sensitive logs.
- Keep dependencies pinned; monitor changelogs for breaking changes.
- Provide users with clear prompts and allow explicit confirmation on the device for all high-value operations.
UX & accessibility
Design text-first transaction displays (amount, address, fee) and ensure keyboard navigation and ARIA attributes for screen readers. Offer fallback flows such as offline copy-and-verify for low-bandwidth or accessibility-sensitive scenarios.
Release & maintenance
Adopt CI that runs linting, unit tests, and static security scans. Publish clear release notes and migration guides when changing derivation paths or supported networks. Coordinate breaking changes with the community via blog and GitHub issues to reduce disruption.
