Usage

import { SecuxBCH, ScriptType } from "@secux/app-bch";

First, create instance of ITransport

• Web Usb
• Web Bluetooth
• React Native Bluetooth

Examples

1. Get address by BIP32 path

const address = SecuxBCH.getAddress(
    device,
    "m/44'/145'/0'/0/0"
);

// p2sh address
const address = SecuxBCH.getAddress(
    device,
    "m/49'/145'/0'/0/0"
);

1. sign transaction

const inputs = [
    {
        hash: "b4a0e0afd8bf99b8360a22a091b1601dc5bdbdda1ab2ab2d7e74f60f97a1f4ad",
        vout: 0,
        // for p2pkh, the raw transaction of utxo is needed
        txHex: "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",
