• Well-documented integration points
• Strong security model and user consent flows
• Active community and open-source tooling

Official resources

Always cross-check integration details on the official developer documentation: https://suite.trezor.io.

Quickstart — get running in 10 minutes

Prerequisites

Before beginning, make sure you have:

• A Trezor hardware device (Model T or One)
• A modern browser (Chrome, Edge, Firefox)
• Node.js v16+ and npm/yarn
• Basic familiarity with command-line tools

Step 1 — Visit the official portal

Open the Developer Portal and Suite to review the latest SDKs and docs: https://suite.trezor.io. The portal is the canonical distribution point for downloads, release notes, and API references.

Step 2 — Install the JavaScript SDK

Most web integrations use the official JavaScript libraries. Install with npm:

npm install @trezor/connect @trezor/suite-web

Minimal example

// index.js
import TrezorConnect from '@trezor/connect';

async function run(){
  const response = await TrezorConnect.getPublicKey({ path: "m/44'/0'/0'/0/0" });
  if(response.success) console.log('pubkey', response.payload);
  else console.error('error', response.payload);
}
run();

For reference and the most up-to-date libraries, consult: https://suite.trezor.io.

Developer Portal structure

Documentation areas

The Developer Portal typically organizes content into:

• Getting started and quickstart guides
• API references and SDK downloads
• Security whitepapers and model descriptions
• Release notes and versioned changelogs

Where to find roadmap & changelogs

Release notes, security advisories, and roadmap entries are maintained in the official portal — start at the Hub: https://suite.trezor.io.

APIs & SDKs

Trezor Connect

Trezor Connect is the canonical API layer that exposes device operations to web/native applications. It wraps device protobufs and manages transport (USB, WebUSB, Bridge). Typical operations include key derivation, signing, and device management.

Common endpoints / methods

• getPublicKey — derive a public key for a path
• signTransaction — request a signature for a transaction payload
• cipherKeyValue — perform device-backed encryption/decryption
• wipeDevice / resetDevice — device lifecycle operations

SDK languages

Primary SDKs are maintained for JavaScript / TypeScript. Community wrappers exist for other languages; always verify with the official portal before production use: https://suite.trezor.io.

Transport and connectivity

Trezor uses WebUSB, Trezor Bridge (native helper), or USB HID. The SDK abstracts these details so your app code can remain transport-agnostic.

Security model — principles & best practices

Hardware-backed keys

Private keys never leave the hardware device. The developer's role is to orchestrate signed requests and to ensure UX prompts are clear for users. For in-depth security principles, consult the portal: https://suite.trezor.io.

Best practices

1. Never send raw private keys to remote servers.
2. Keep signing requests minimal — avoid unnecessary data exposure.
3. Use path derivation standards (BIP32/BIP44/BIP39) appropriately.
4. Present clear transaction details to users before signing.
5. Implement rate-limiting / request validation on backends that coordinate with devices.

Secure UX patterns

Ensure the user confirms each high-risk action on the device. Provide human-readable descriptions and visual confirmations in your app while leaving cryptographic attestation to the device.

Example integrations and recipes

Connect a web dApp

Below is a practical recipe for integrating Trezor Connect into a browser dApp. The flow: (1) request connection, (2) get public key, (3) build transaction, (4) ask device to sign.

// simple-dapp.js
import TrezorConnect from '@trezor/connect';

async function connectDevice(){
  const res = await TrezorConnect.openWallet();
  if(!res.success) throw new Error('failed to open wallet');
}

async function getAddress(){
  const pk = await TrezorConnect.getPublicKey({ path: "m/44'/60'/0'/0/0" });
  return pk.payload;
}

async function signTx(tx){
  const sig = await TrezorConnect.signTransaction({
    inputs: tx.inputs,
    outputs: tx.outputs,
    coin: tx.coin
  });
  if(sig.success) return sig.payload; else throw new Error(sig.payload.error);
}

Server-side considerations

Servers should treat devices as stateless signers. A safe pattern: server prepares an unsigned transaction payload and sends it to the client; the client requests a signature from the device and returns the signed transaction to the server for broadcast.

Link back to the portal

Always validate your implementation against the current API reference: https://suite.trezor.io.

UX & UI guidelines

Show meaningful data

When requesting signatures show exact amounts, recipients, and fees. Where possible, standardize how you display addresses and amounts so users can easily verify them before confirming on the device.

Error handling

Graceful error handling includes clear user messages, retry paths, and guidance for device connectivity issues (e.g., reconnect USB, open Bridge). The official troubleshooting documentation is a good reference: https://suite.trezor.io.

Testing, CI and release considerations

Simulators and test devices

Use emulators or dedicated test devices for CI to avoid exposing production hardware. When writing system tests, simulate device responses when possible to keep pipelines deterministic.

Version pinning

Pin SDK versions in your package manifest and maintain a changelog that tracks the official portal releases: https://suite.trezor.io.

Troubleshooting common issues

Device not detected

Check device firmware, USB cable, browser permissions, and whether Trezor Bridge is installed (if required). Consult the official troubleshooting docs: https://suite.trezor.io.

Signature mismatch

Confirm the transaction inputs/outputs and derivation paths. Make sure the device firmware and SDK are compatible (version mismatch is a frequent cause).

Example: small embed component (HTML + JS)

Embed-ready snippet

Drop this snippet into a page to provide a minimal "Get Public Key" button integrated with Trezor Connect. This code assumes you've installed the official library and served it appropriately.

<button id="getPk">Get Public Key</button>
<pre id="out"></pre>

<script type="module">
  import TrezorConnect from 'https://cdn.jsdelivr.net/npm/@trezor/connect/lib/esm/index.js';
  document.getElementById('getPk').addEventListener('click', async () => {
    try{
      const res = await TrezorConnect.getPublicKey({path: "m/44'/60'/0'/0/0"});
      document.getElementById('out').textContent = JSON.stringify(res, null, 2);
    }catch(e){
      document.getElementById('out').textContent = e.message;
    }
  });
</script>

Verify example behavior against official docs: https://suite.trezor.io.

Legal, licensing & compliance

Open-source components

Trezor tools often leverage permissive open-source licenses. When distributing software that integrates with Trezor Suite, comply with the license terms of any SDK and the project’s contribution guidelines available on the portal: https://suite.trezor.io.

Security disclosures

Follow responsible disclosure processes if you discover vulnerabilities; the portal and official channels list contact methods for reporting security issues.
