Trezor Suite® – Getting Started™ Developer Portal

Overview

Trezor Suite provides a secure, user-friendly interface and APIs for interacting with hardware wallets. Whether you are building desktop apps, web integrations, or backend services that require secure signing and transaction workflows, the Trezor Suite Developer Portal covers the essentials: installation, API usage, sample code, and security best practices.

Keywords (for reference): Trezor Suite, Trezor Suite, Trezor/Suite, Trezor Suite, Trezor Suite, Trezor/Suite

Quick Start — Install & Connect

Download Trezor Suite — Obtain the latest Trezor Suite binary or run the web Suite depending on your platform.
Connect your device — Use a supported USB cable and unlock your Trezor device.
Enable Developer Mode — In Suite settings, toggle developer features to access extended APIs and debug logs.

Once connected, the Suite exposes endpoints and SDKs that let your app request public keys, create transactions, and sign payloads using the user's Trezor device. The typical flow follows: initiate request → user confirms on device → Suite returns signed response.

APIs & SDKs

Trezor Suite supports multiple integration layers:

Web SDK — Use the browser-based API for web apps that interact with the Suite via the native messaging bridge.
Desktop integration — Electron and native apps can communicate with Suite through IPC or the provided libraries.
Command-line / Headless — Scripts and CI processes may use the CLI tools for automated signing (with appropriate security constraints).

Sample: Request public key (pseudo-code)

// initialize connection to Trezor Suite
const suite = await TrezorSuite.connect();
// request a public key from a specific BIP32 path
const pubkey = await suite.getPublicKey("m/44'/0'/0'/0/0");
console.log(pubkey);

Integration Patterns & Examples

Common integrations include:

Wallet connectors — Abstract Trezor Suite as a connector module in multi-wallet frontends.
Transaction relays — Use Suite for signing while broadcasting transactions through your own node or third-party relayer.
Authentication — Implement hardware-backed authentication by having users sign nonces with their hardware wallets.

Example: Sign a transaction

const tx = { to: "0xabc...", value: "1000000000000000000" };
const signed = await suite.signTransaction(tx);
// broadcast signed.rawTransaction to the network

Always display clear, human-readable descriptions for any action that will be confirmed on the device. Users must be able to verify the purpose of every signature they approve.

Security Best Practices

Security is fundamental when integrating with Trezor Suite. Follow these guidelines:

Never transmit private keys or seed phrases. Trezor Suite keeps private keys on-device; design your architecture so secret material never leaves the hardware wallet.
Use explicit user consent. Any signing operation should require confirmation on the physical device.
Keep dependencies up to date and validate any third-party libraries that interact with the Suite APIs.
Implement origin checks for web integrations so only trusted origins can request signing operations from the Suite bridge.

Developer Tools & Debugging

Developer mode unlocks verbose logs and diagnostic tools. Use the Suite logs to trace message flows and confirm that your requests are well-formed. For CLI integrations, redirect logs to files and rotate them securely.

When debugging, keep these tips in mind:

Reproduce issues with test-wallets and never use production seed phrases during development.
Capture HID or WebUSB traces when device communication fails; these traces help identify connection and transport errors.
If you encounter signing mismatches, verify the exact BIP paths, address encoding, and chain-specific parameters.

Frequently Asked Questions

1. What platforms does Trezor Suite support?: Windows, macOS, and Linux desktops are supported along with a web-based Suite experience. Mobile support is limited — prefer desktop or web integrations for developer flows.
2. Can I automate signing in CI?: Automating signing in CI is strongly discouraged unless using dedicated hardware with strict physical security and manual confirmation is still enforced. Use test accounts and never store production seeds in CI.
3. How do I request transaction details so users can verify them?: Provide structured, human-readable fields (destination, amount, fees, memo) with your signing request. Suite will display these on the device for confirmation.
4. Where can I find SDK documentation?: Refer to the Developer Portal and the SDK reference included in the Suite distribution. The docs include code examples, API signatures, and transport details.
5. What should I do if a user loses their device?: Advise them to recover using their recovery seed on a new Trezor device or compatible wallet. Encourage users to keep recovery seeds secure and to revoke or rotate any dependent credentials as necessary.

Conclusion

The Trezor Suite Developer Portal is designed to accelerate secure wallet integrations. By following the quick start, leveraging the provided SDKs, and observing security best practices, you can offer a reliable hardware-backed signing experience to your users.
