Trezor Suite® — Getting Started™ Developer Portal

Build secure hardware wallet integrations quickly — SDKs, API reference, code samples and best practices for connecting to Trezor Suite.

Welcome, developers 👋

Whether you're building a desktop wallet, browser extension, exchange integration, or custody product, Trezor Suite gives you battle-tested building blocks for secure crypto operations. This portal focuses on quickstarts, secure patterns, sample code, and performance tips — all designed to help you launch faster and safer.

Bridge & WebUSB
Secure Signing
Account Management
Testnet Support

Getting started — 3 steps to integration

1. Setup your environment

Install Trezor Suite SDK, set up Node.js, and enable WebUSB or Bridge for local dev.

2. Connect and enumerate

Discover connected Trezor devices, request user permission, and securely open a session for signing flows.

3. Sign transactions

Use recommended message formats and deterministic transaction builders to create signatures verified by the device.

Quick code sample

// Sample: connect & get public key
import Trezor from 'trezor-suite-sdk';
async function getXpub(){
  const device = await Trezor.connect();
  const xpub = await device.getPublicKey("m/44'/0'/0'");
  console.log(xpub);
}

This quick sample demonstrates the minimal flow: connect, request xpub, and close the session. Full examples are available for React, Electron, and pure Node.

Best practices & security

  • Never transmit private keys or seeds over the network — use the Trezor device to sign offline.
  • Always validate user prompts and show transaction details clearly before requesting a signature.
  • Use the latest firmware compatibility matrix and pin device model checks on critical flows.
  • Support testnets and feature flags to allow safe development without mainnet funds.

Docs & resources

This portal contains:

  • Full API reference (endpoints, params, and response shapes).
  • SDK downloads and changelogs for JS, Python, and Rust.
  • Tutorials: build a web wallet, add exchange withdrawals, integrate multi-sig.
  • Sample apps on GitHub with ready-to-run demos and CI configs.

Frequently Asked Questions

  1. Q: Do I need a physical Trezor device to develop?
    A: For full testing and signing flows, yes. Emulators and test mocks are available for unit tests.
  2. Q: Which networks are supported?
    A: Bitcoin, Ethereum and major EVM chains, plus various altcoins. See the compatibility matrix in the API docs for details.
  3. Q: Can I use Trezor Suite in Electron?
    A: Yes — we provide Electron-ready SDK examples and packaging recommendations for native integration.
  4. Q: How are firmware updates handled?
    A: Firmware updates are signed and verified by the device. Integrations should detect outdated firmware and guide users to update in Trezor Suite.
  5. Q: Where can I report a security issue?
    A: Use the responsible-disclosure channel listed on this portal. We prioritize security reports and will respond with remediation steps.
