# `@secux/app-luna`

> SecuX Hardware Wallet LUNA API

## Usage

```ts
import { SecuxLUNA } from "@secux/app-luna";
```

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

<br />

## Examples
1. Get account address
```
const path = "m/44'/330'/0'/0/0";
const address = await device.getAddress(path);

/*

// transfer data to hardware wallet by custom transport layer
const data = SecuxLUNA.prepareAddress(path);
const response = await device.Exchange(data);
const address = SecuxLUNA.resolveAddress(response);

*/
```

2. Sign transaction
    - transfer asset (MsgSend)
    ```ts
    const signer = {
        path: "m/44'/330'/0'/0/0",
        accountNumber: 12345,
        sequence: 1,
    };
    const params = {
        fee: { uluna: 3000 },
        gasLimit: 12345,
    };
    const send = new SecuxLUNA.MsgSend(from, to, { uluna: 1e6 });

    const { multi_command, serialized } = await device.sign(
        [signer],
        [send],
        params
    );
    const responseList = [];
    for (const data of multi_command) {
        const rsp = await device.Exchange(data);
        responseList.push(rsp);
    }
    const raw_tx = SecuxLUNA.resolveTransaction(responseList, serialized);

    /*

    // transfer data to hardware wallet by custom transport layer.
    const { commands, serialized } = SecuxLUNA.prepareSign(
        [
            { ...signer, publickey: "02acb4bc267db7774614bf6011c59929b006c2554386a3090baff0b3fc418ec044" }
        ],
        [send],
        params
    });
    const responseList = [];
    for (const data of commands) {
        const rsp = await device.Exchange(data);
        responseList.push(rsp);
    }
    const raw_tx = SecuxLUNA.resolveTransaction(responseList, serialized);

    */
    ```
