const path = "m/44'/714'/0'/0/0";
const address = await device.getAddress(path);

/*

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

*/

2. Sign transaction

const { raw_tx, signature } = await deivce.sign(
"m/44'/714'/0'/0/0",
{
to: "bnb17jr3n9xaxm92fp5dznuazql2c2x6ypw2gvuvmy",
amount: 1e18
}
);

/*

// transfer data to hardware wallet by custom transport layer
const data = SecuxBNB.prepareSign(
"m/44'/714'/0'/0/0",
