Trezor Suite® – Getting Started™ Developer Portal

Overview

The Trezor Suite® – Getting Started™ Developer Portal is designed to help developers seamlessly integrate with Trezor hardware wallets, build secure applications, and manage user interactions. Whether you're writing a wallet interface, building exchange integrations, or implementing high-level tools, this portal is your guide.

In this portal you’ll find:

Comprehensive setup guides and environment configuration
Detailed API references and specifications
Code samples in JavaScript, Python, and more
Interactive playgrounds and demos
Community support, issue trackers, and contribution guidelines

We aim to keep this portal colorful, versatile, and developer-friendly. The example site you're reading mirrors the same design approach—clean, modern, and engaging.

Getting Started – Setup & Installation

Before writing code that interacts with a Trezor device, ensure you have the prerequisites properly installed and configured.

Prerequisites

Here’s what you’ll need:

Node.js & npm (v14+ recommended)
Access to a Trezor hardware device (Trezor Model T or One)
Firmware up to date (check Trezor Suite → Settings → Firmware)
Understanding of JavaScript / TypeScript and web communications (HTTP / WebUSB / WebHID / WebSocket)

Installation Steps

Create a new project directory:
```
mkdir trezor-dev && cd trezor-dev
```
Initialize a new Node.js project:
```
npm init -y
```
Install the Trezor Connect library:
```
npm install --save @trezor/connect
```
Set up a simple HTML + JS file to test the connection.

Basic Example

Here’s a minimal example in JavaScript that connects to your Trezor and fetches the public key:

      
        import TrezorConnect from '@trezor/connect';
        TrezorConnect.init({
          connectSrc: 'https://connect.trezor.io/8/',  // adjust version
          popup: true,
        }).then(() => {
          TrezorConnect.getPublicKey({
            path: "m/44'/0'/0'/0/0"
          }).then(response => {
            if (response.success) {
              console.log('Public key:', response.payload.publicKey);
            } else {
              console.error('Error:', response.payload.error);
            }
          });
        });
      
    

This example demonstrates: initialization, requesting a public key, and handling success or error responses. Subsequent calls can include signing, transaction building, and more.

API Reference & Important Endpoints

The Trezor Developer Portal provides a full API reference for the Trezor Connect library, explaining all methods, arguments, return types, and error codes.

Core Methods

init() — initializes the library with options like environment, popup handling, debugging.
getPublicKey(params) — returns a public key for a given BIP32 path.
signTransaction(params) — signs transactions, supporting Bitcoin, Ethereum, and many more.
ethereumSignMessage(params) — sign messages for Ethereum protocols.
cardanoSignTransaction(params) — specialized signing for Cardano network transactions.
wipeDevice(), resetDevice(), applySettings() — device management methods.

Common Parameters

path — BIP32 hierarchical deterministic path (e.g. "m/44'/60'/0'/0/0").
coin — which coin (e.g. "btc", "eth").
inputs / outputs — array of transaction inputs/outputs.
u32, u64, buffer — used in certain signing or firmware operations.

Error Codes & Responses

Each API method returns a uniform response:

On success:
```
 { success: true, payload: { ... } } 
```

On failure:

 { success: false, payload: { error: "Error message or code" } }

The portal includes an error catalog with descriptions for standard error codes (like ActionCancelled, Device_Not_Found, Transport_Struct, etc.) so you can implement proper error handling and user feedback.

Examples & Interactive Demonstrations

Learning by example is often faster than reading documentation. Here we provide code snippets, sandbox environments, and interactive demos.

Browser Example (JavaScript)

Below is a small interactive demo (simulated) that uses colors to indicate state:

Status: Disconnected

Use Cases

Wallet Front‑end Integration: Build React, Vue, or Svelte apps that call Trezor Connect to get keys, sign, verify, etc.
Exchange / Custodial Services: Let your users withdraw crypto via Trezor-signed transactions.
Blockchain Tools: Build explorers, transaction builders, validators, or dashboard tools that integrate hardware wallet security.
Mobile & Hybrid Apps: Use WebUSB / WebHID / Bridge to support Trezor in cross-platform apps.
