The Trezor Suite Developer Portal is the central hub for building secure wallets, merchant integrations, and experimental applications that interact safely with Trezor hardware wallets. Whether you are prototyping an app to read public keys or developing a custody service, this portal helps you make informed architectural decisions and follow best practices.
Visit the official developer portal here for documentation, SDKs, and integration guides.
Trezor hardware wallets securely store private keys in a dedicated secure element chip. The device only exposes safe operations such as signing, key derivation, and public key export through well-defined host interfaces.
Trezor Suite is the official desktop and web application that communicates with the hardware device, providing users with a polished and secure user interface for managing their crypto assets.
The Developer Portal provides technical resources including API references, SDKs, examples, and best practices to aid engineers, security auditors, and product teams in building on top of Trezor's ecosystem.
Download the official Trezor Suite desktop app for Windows, macOS, or Linux, or use the web app. Complete the device setup following the official onboarding flow.
Use a compatible USB cable and connect your Trezor device. Ensure Trezor Bridge or appropriate WebUSB support is enabled in your browser for web apps.
Access the API documentation and SDK references for JavaScript and backend integrations on the official portal.
Trezor Connect is the most popular JavaScript library for browser-based signing and key management. Initialize the library and request user operations through the device.
// Initialize Trezor Connect
TrezorConnect.init({
connectSrc: 'https://connect.trezor.io/8/',
popup: true
});
// Example: request public key
const response = await TrezorConnect.getPublicKey({ path: "m/44'/0'/0'/0/0" });
if (response.success) {
console.log('Public key:', response.payload.publicKey);
} else {
console.error('Error:', response.payload.error);
}
Use test networks and sandbox wallets to verify your integration. Keep device firmware and Suite versions updated to maintain compatibility.
getPublicKey – Retrieve a public key from the device.getAddress – Obtain cryptocurrency addresses.signTransaction – Request a transaction signature securely.signMessage – Sign arbitrary messages for proof of ownership.Strictly observe rate limits on any remote Developer APIs to avoid service disruptions.
After shipping, continuously monitor SDK updates, device firmware changes, and security advisories. Plan for API key rotation and quick response to security incidents.
Pin SDK versions and review updates regularly, e.g., monthly, with contingency plans for breaking changes.
