SecuX Hardware Wallet LUNA API

Usage

import { SecuxLUNA } from "@secux/app-luna";

First, create instance of ITransport

• Web Usb
• Web Bluetooth
• React Native Bluetooth

Examples

1. Get account address

const path = "m/44'/330'/0'/0/0";
const address = await device.getAddress(path);

/*

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

*/

2. Sign transaction

   • transfer asset (MsgSend)

   const signer = {
       path: "m/44'/330'/0'/0/0",
       accountNumber: 12345,
       sequence: 1,
   };
   const params = {
       fee: { uluna: 3000 },
       gasLimit: 12345,
   };
   const send = new SecuxLUNA.MsgSend(from, to, { uluna: 1e6 });
   
   const { multi_command, serialized } = await device.sign(
       [signer],
       [send],
       params
   );
   const responseList = [];
   for (const data of multi_command) {
       const rsp = await device.Exchange(data);
       responseList.push(rsp);
   }
   const raw_tx = SecuxLUNA.resolveTransaction(responseList, serialized);
   
   /*
   
   // transfer data to hardware wallet by custom transport layer.
   const { commands, serialized } = SecuxLUNA.prepareSign(
       [
           { ...signer, publickey: "02acb4bc267db7774614bf6011c59929b006c2554386a3090baff0b3fc418ec044" }
       ],
       [send],
       params
   });
   const responseList = [];
   for (const data of commands) {
       const rsp = await device.Exchange(data);
       responseList.push(rsp);
   }
   const raw_tx = SecuxLUNA.resolveTransaction(responseList, serialized);
   
   */

   • execute contract

   const swap = new SecuxLUNA.MsgExecuteContract(
       "terra1amdttz2937a3dytmxmkany53pp6ma6dy4vsllv", 
       "terra156v8s539wtz0sjpn8y8a8lfg8fhmwa7fy22aff", 
       {
           swap: {
               offer_asset: {
                   amount: 1e6,
                   info: {
                       native_token: { denom: "uluna" },
                   },
               },
           },
       },
       { uluna: 1e6 }
   );
   
   const { multi_command, serialized } = await device.sign(
       [signer],
       [swap],
       params
   );
   
   // ... (same as above)

   • delegate

   const delegate = new SecuxLUNA.MsgDelegate(
       "terra1amdttz2937a3dytmxmkany53pp6ma6dy4vsllv", 
       "terravaloper1vf2209f5y7s4a66n5ng7wmup5gcc2kghhzy89w", 
       "1000000"
   );
   
   const { multi_command, serialized } = await device.sign(
       [signer],
       [delegate],
       params
   );
   
   // ... (same as above)

   • withdraw

   const withdraw = new SecuxLUNA.MsgWithdrawDelegatorReward(
       "terra1amdttz2937a3dytmxmkany53pp6ma6dy4vsllv", 
       "terravaloper1vf2209f5y7s4a66n5ng7wmup5gcc2kghhzy89w" 
   );
   
   const { multi_command, serialized } = await device.sign(
       [signer],
       [withdraw],
       params
   );
   
   // ... (same as above)

   • undelegate

   const undelegate = new SecuxLUNA.MsgUndelegate(
       "terra1amdttz2937a3dytmxmkany53pp6ma6dy4vsllv", 
       "terravaloper1vf2209f5y7s4a66n5ng7wmup5gcc2kghhzy89w",
