Why build with Trezor Suite Developer Portal?

Developers building secure wallet integrations choose the Trezor Suite Developer Portal because it offers a clean Getting Started path, powerful Trezor API access, and SDKs designed for both desktop and web apps. Whether you're building recovery flows, transaction signing, or multisig integrations, the Developer Portal centralizes API docs, sample code, security guidance, and testnet tools.

Quick start — 5 steps to a working integration

1. Create a Developer Account

Sign up in the portal, generate API keys, and register your app for testing with Trezor Suite sandbox.

2. Install SDK

Install the official SDK (npm or yarn). The Trezor SDK supports hardware communication, signing, and device management.

3. Connect Device

Use the Trezor Bridge or WebUSB with clear onboarding flows—test for USB and WebHID compatibility.

4. Implement Signing Flow

Call the Trezor API to prepare transactions, request a signature, and verify signed payloads. Follow recommended cryptographic verification steps.

5. Test & Submit

Run end-to-end tests on testnet, audit the UX and security prompts, and submit your integration for review if required.

Minimal sample (JavaScript)

// Connect to a Trezor device and request public key (example)
import TrezorConnect from 'trezor-connect';

TrezorConnect.init({manifest: {email: 'dev@example.com', appUrl: 'https://your.app'}});

async function getPublicKey(){
  const res = await TrezorConnect.getPublicKey({path: "m/44'/0'/0'/0/0"});
  if (res.success) {
    console.log('Public key:', res.payload.publicKey);
  } else {
    console.error('Error:', res.payload.error);
  }
}

Security & best practices

  • Always validate signed payloads on the server side and confirm nonces to prevent replay.
  • Use the latest SDK versions and prefer WebHID or Bridge with explicit user consent.
  • Show clear user prompts—display transaction details on both host UI and device screen.
  • Follow recovery and backup guidance—never request seed words from users.
