SecuX Hardware Wallet XRP API

Usage

import { SecuxXRP } from "@secux/app-xrp";

First, create instance of ITransport

• Web Usb
• Web Bluetooth
• React Native Bluetooth

Examples

• Get address of bip44 path

const address = await device.getAddress("m/44'/144'/0'/0/0");

/*

// transfer data to hardware wallet by custom transport layer.
const data = SecuxXRP.prepareAddress("m/44'/144'/0'/0/0");
const response = await device.Exchange(data);
const address = SecuxXRP.resolveAddress(response);

*/

• Sign transaction

let payment = {
    TransactionType: "Payment",
    Account: "rD17Ez7fBpuwVp6smfjYhPKD3pwiN5QGKX",
    Destination: "rGNitVptpmpCNYC23LbQ9yfCnAf1Z6gq7X",
    amount: 1e6
};

// fetch data from XRP api
const { BroadcastClient } = require("xrpl");
client = new BroadcastClient(["wss://s1.ripple.com"]);
await client.connect();
payment = await client.autofill(payment);

// sign
const raw_tx = await device.sign("m/44'/144'/0'/0/0", payment);

/*

// transfer data to hardware wallet by custom transport layer.
const { commandData, serialized } = SecuxXRP.prepareSign("m/44'/144'/0'/0/0", {
    ...payment,
    SigningPubKey: "026771406ace54da2cae8b168862697ca35bc3db56c90f4270adb307ac9a38fe9c"
});
const response = await device.Exchange(data);
const raw_tx = SecuxXRP.resolveTransaction(response, serialized);

*/

// broadcast
await client.submit(raw_tx);
