SecuX Hardware Wallet ETH API

Usage

import { SecuxETH } from "@secux/app-eth";

First, create instance of ITransport.


Examples

  1. Get address derived by given BIP44 path.
const address = await device.getAddress("m/44'/60'/0'/0/0");

/*

// transfer data to hardware wallet by custom transport layer.
const buffer = SecuxETH.prepareAddress("m/44'/60'/0'/0/0");
const response = await device.Exchange(buffer);
const address = SecuxETH.resolveAddress(response);

*/
  1. Sign legacy transaction (EIP-155).
const { raw_tx, signature } = await device.sign(
    "m/44'/60'/0'/0/0",
    {
        nonce: 0,
        to: "0xD080156885651fADbD6df14145051b934660a748",
        value: 1e10,
        chainId: 1,
        gasPrice: 1e6,
        gasLimit: 25000
    }
)

/*

// transfer data to hardware wallet by custom transport layer.
const { commandData, rawTx } = SecuxETH.prepareSignEIP155(
    "m/44'/60'/0'/0/0",
    {
