SecuX Hardware Wallet ADA API

Usage

import { SecuxADA, AddressType } from "@secux/app-ada";

First, create instance of ITransport

• Web Usb
• Web Bluetooth
• React Native Bluetooth

Examples

1. Get shelley address

   • base address

   const path = "m/1852'/1815'/0'";
   const address = await device.getAddress(path, AddressType.BASE);
   
   /*
   
   // transfer data to hardware wallet by custom transport layer
   const data = SecuxADA.prepareAddress(path);
   const response = await device.Exchange(data);
   const address = SecuxADA.resolveAddress(response, AddressType.BASE);
   
   */
   

   • reward address

   const path = "m/1852'/1815'/0'";
   const address = await device.getAddress(path, AddressType.REWARD);
   

2. Sign transaction

           index: 1,
           amount: 12663894,
           // for custom transport layer, each utxo needs xpublickey.
           // xpublickey: "c232950d7c27b78542795ce4cad053e8dfaab7679ba5477563be5c60c1a4d0613fc81fd9bb8f30822c1252c29cc6af147831da44fb86acad6c04fcc95700b92b"
