Welcome — why build for Trezor Suite?
Modern wallets need secure UX
Hardware wallets remain the gold standard for private key storage. Trezor Suite is more than a wallet UI — it's an ecosystem that enables third-party integrations, secure signing, and developer tooling. Whether you're building a dApp, an exchange integration, or tooling for enterprise key management, this portal will give you the foundation and the inspiration to ship faster.

Getting started
Prerequisites
Before you begin, make sure you have:
- A Trezor hardware device (Trezor Model T or Trezor One)
- Latest Trezor Suite or Trezor Bridge installed (for older flows)
- A modern browser that supports WebUSB or WebHID (Chrome, Edge, or other Chromium-based browsers)
- Basic knowledge of key management and cryptographic signing
Quick start: a minimal connection flow
This example shows the conceptual steps your app will take to request access and sign a message via a Trezor device.
// 1. Request device access (WebUSB / WebHID)
const device = await requestTrezorDevice();
// 2. Initialize session and get features
await device.connect();
const info = await device.getFeatures();
// 3. Request user confirmation and sign
const signature = await device.signMessage({ path: "m/44'/60'/0'/0/0", message: "Authorize transaction" });
Notes on consent
Always surface clear, contextual prompts that explain what the device will sign and why. Users must confirm every critical operation on their Trezor device — build your UI to make that flow obvious.
Integration guide
Choose your transport
Trezor supports multiple transports. Your choice affects UX, browser compatibility, and deployment complexity.
- WebUSB — direct browser device access for modern browsers.
- WebHID — for HID-compatible devices and slightly different permission flows.
- Trezor Connect — a hosted SDK method offering a uniform API and fallback transports.
Using Trezor Connect (recommended for fastest integration)
Trezor Connect abstracts transports and provides a secure iframe-based flow. It offers convenient methods to get addresses, sign transactions, and more.
// basic Trezor Connect use
import TrezorConnect from 'trezor-connect';
TrezorConnect.getPublicKey({ path: "m/44'/60'/0'/0/0" })
.then(response => console.log(response))
.catch(err => console.error(err));
Offline & batch signing
For high-value deployments, consider a batched signing model where the host software prepares multiple transactions offline and the operator signs them physically at the device — this limits online exposure and keeps the hardware offline as much as possible.
Security & best practices
Never request sensitive secrets
Third-party apps must never ask users to reveal recovery seeds or private keys. If your flow requires seed export, ensure it's only performed by the user via device UI, never programmatically.
Use explicit consent and minimize scopes
Design APIs and permission prompts with minimal scopes — ask for the exact access you need (signing a single tx, not full account control).
Logging and telemetry
Be cautious with telemetry — never log signatures, raw messages, or private metadata that could allow replay attacks. Aggregate usage metrics instead.
Examples & sample workflows
dApp integration (Ethereum)
For Ethereum dApps, implement the following pattern: request address → present nonce & gas to user → call device to sign → broadcast. Keep gas estimates transparent and show human-readable transaction summaries.
Multi-account management
Allow users to manage derivation paths and label accounts. Expose a UI to switch between accounts, and store only the account identifier (never private key material).
// Example: fetch address and show in UI
const response = await TrezorConnect.getAddress({ path: "m/44'/60'/0'/0/0" });
if (response.success){
showAddress(response.payload.address);
}
Design & UX tips for developer portals
Make consent visual
Use step indicators, clear titles, and short human-readable summaries for each step that the Trezor device will confirm. Visual cues reduce user error.
Onboarding checklist
- Explain device requirements
- Show a sample signed message
- Provide troubleshooting steps and a fallback
Internationalization
Localize all user-facing strings, especially those near security prompts. Mistranslation near a signing confirmation can lead to irreversible mistakes.
Conclusion — ship confidently
Building with Trezor Suite is an opportunity to combine best-in-class hardware security with beautiful UX. Follow the integration patterns in this guide, respect user consent, and provide clear, designer-friendly flows that make crypto safer for everyone.
