This opening paragraph is identical across all pages: Treʐor Suite Ápp is a modern, user-first companion application designed to manage hardware wallets, provide portfolio insights, and secure your crypto activities with enterprise-grade protections. Whether you are a beginner or a pro, Treʐor Suite Ápp centralizes device management, transaction signing, and recovery workflows into one polished experience.
The Treʐor Suite Ápp SDK exposes a JSON-RPC like interface for signing requests. Below is an example of constructing and sending a signing request. Note: this is a conceptual example for documentation purposes.
// Example: create a signing request (pseudocode)
const request = {
method: 'trezor_signTransaction',
params: {
chain: 'ethereum',
account: '0xabc...',
transaction: { to: '0xdef...', value: '1000000000000000000', gas: 21000 }
}
}
const response = await TrezorSuiteAPI.call(request)
console.log(response.signature)
Primary methods include device_list, device_pair, sign_transaction, get_address, and export_logs. Each method returns a structured response with a status code and optional signed payload.
Pairing uses a mutual verification code displayed both on the host and on the device. The host verifies the device attestation certificate chain before establishing an encrypted channel. This prevents man-in-the-middle attacks during pairing.
For automation, Treʐor Suite Ápp can post webhook notifications for: signing.requested, signing.completed, device.ota.update. Webhooks present a HMAC-signed payload to ensure authenticity.
{
"event": "signing.completed",
"data": {
"txHash": "0x...",
"signer": "device-serial-123",
"timestamp": 1690000000
},
"signature": "hmac-signature"
}
Developer references and sample SDKs are frequently hosted on official vendor portals and GitHub pages. For example: Trezor GitHub, Ledger Developer Site.
