# `@secux/protocol-transaction`

> SecuX Hardware Wallet transcation related protocol API

## Usage

```ts
import { EllipticCurve, SecuxTransactionTool } from "@secux/protocol-transaction";
```

First, create instance of ITransport
- [Web Usb](https://www.npmjs.com/package/@secux/transport-webusb)

## Examples
1. Query publickey from SecuX Hardware Wallet
```ts
const data = SecuxTransactionTool.getPublickey("m/44'/0'/0'/0/0", EllipticCurve.SECP256K1);
const response = await device.Exchange(data);
const publickey = SecuxTransactionTool.resolvePublickey(
    response, 
    EllipticCurve.SECP256K1,
    true // SECP256K1 compress flag
);
```

2. Query extended publickey from SecuX Hardware Wallet
```ts
const data = SecuxTransactionTool.getXPublickey("m/44'/0'/0'/0/0");
const response = await device.Exchange(data);
const xpub = SecuxTransactionTool.resolveXPublickey(response, "m/44'/0'/0'/0/0");
```
