Trezor Suite® – Getting Started™ Developer Portal

Overview

Welcome to the Trezor Suite Developer Portal. This single-file starter gives you human-friendly guidance and copy-paste-ready HTML sections (with <h1> through <h5> examples) so you can prototype documentation pages, developer guides, or an onboarding presentation. The content below blends practical steps, security notes, and integration tips for wallets, dApps, and merchant integrations.

Who is this for?

Engineers building integrations with Trezor hardware and Trezor Suite, technical writers producing docs, and product teams shipping secure wallet experiences. It assumes familiarity with web APIs, npm, and standard crypto concepts like public keys, signatures, and transaction serialization.

Quickstart — Connect & Sign

1. Install Trezor Suite & Tools

Install the Trezor Suite app for desktop or use the web Suite. For development, the trezor-connect JavaScript SDK and the Suite monorepo are primary entry points. Connect your Trezor device via USB or Bluetooth (model dependent), open the Suite, and confirm the device unlock.

2. Minimal web integration (example)

<!-- Minimal SDK usage for a web page -->
<script src="https://connect.trezor.io/9/trezor-connect.js"></script>
<script>
  TrezorConnect.getPublicKey({
    path: "m/44'/0'/0'/0/0"
  }).then(result => console.log(result)).catch(err => console.error(err));
</script>

Notes

Use the official Connect Explorer and the Suite documentation for full API references and message schemas. Always test on a device with non-sensitive testnets or test accounts before production.

Troubleshooting

Ensure firmware is up to date.
Verify the host OS recognizes USB devices and no other process has taken exclusive access.
Check browser console for CORS or content-security errors when using web integrations.

SDKs & APIs

There are several entry points depending on your platform and language: Trezor Connect (JS), library bindings, and references in the Suite monorepo. For advanced integrations consider the Suite packages and the connect explorer.

Recommended SDKs

Trezor Connect — JavaScript SDK for web & Electron apps.
Trezor Suite packages — monorepo for deep Suite integration and UI components.
Community bindings — language-specific wrappers (review for maintenance before shipping).

Best practices

Never transmit raw seed material. The device signs locally; keep the flow off-host.
Validate user intent on-device by prompting meaningful messages for transaction details.
Pin, fingerprint, or passphrase flows should use consistent UX across platforms.

Security Notes

Security is the primary value of using Trezor. Your integration must reflect that by minimizing attack surface and increasing user visibility on transaction details. Follow these rules:

Do

Keep all cryptographic operations on the device.
Provide clear, human-readable transaction details before asking users to confirm on-device.
Use transport-layer encryption for any host-to-backend communication.

Don't

Never store unrecoverable private data on your servers.
Avoid generating recovery seeds outside device-built flows.

Examples & Patterns

Wallet Integration Flow

1) Detect device, 2) Request public key / account discovery, 3) Build unsigned transaction, 4) Ask device to sign, 5) Broadcast via reliable node or provider. Use deterministic derivation paths and show derivation info in UI.

Merchant & Exchange Patterns

For custodial or merchant flows, wrap hardware signing in an air-gapped or HSM + Trezor-assisted signing policy. Log audit trails, and make emergency key-rotation processes auditable.

Testing tip

Automate device-level tests with integration rigs and mock connectors where possible. Remember to include manual device confirmations in acceptance tests.

Official Resources (Quick Links)

Below are curated official links to documentation, guides, and source code. Use them as primary references when implementing integrations.

License & contribution

Most client-side libraries and Suite packages are open-source. Check each repo's license and contribution guidelines before forking or embedding.
