Introduction

This is frok from Hydro-SDK-Wallet

Basic Usage Guide

This package requires React and Redux.

Step1: install npm package

npm i @jeonggonmun/exnomy-wallet

Step2: Wallet Reducer

The store should know how to handle actions coming from the wallet components. To enable this, we need to pass the WalletReducer to your store.

import { createStore, combineReducers } from "redux";
import { WalletReducer } from "@jeonggonmun/exnomy-wallet";

const rootReducer = combineReducers({
  // ...your other reducers here
  // you have to pass WalletReducer under 'WalletReducer' key
  WalletReducer
});

const store = createStore(rootReducer);

Step3: Wallet Component

To make the wallet logic work. We need to mount the Wallet and WalletButton components into your app. They should be mounted into Provider(see more details about Provider in react-redux). When the components is initialized, some monitors will start to work as well. They are monitoring the web3 wallet status(not installed, locking, account changed), ledger status(locked or not), and balances of all available addresses. You can config wallet through props. See more datials in the api section below.

import React from "react";
import { Provider } from "react-redux";
import { Wallet, WalletButton } from "@jeonggonmun/exnomy-wallet";
import { store } from "./store";
import "@jeonggonmun/exnomy-wallet/index.css";

class App extends React.Component {
  render() {
    return (
      <Provider store={store}>
        // ... your components
        <Wallet nodeUrl="https://ropsten.infura.io" />
        <WalletButton />
      </Provider>
    );
  }
}

Step4: Use Account

We can get the current selected account by using selector functions.

import React from "react";
import { connect } from "react-redux";

class App extends React.Component {
  signMessage = async () => {
    const { currentAccount } = this.props;
    const signature = await currentAccount.wallet.signPersonalMessage("test message");
    //console.log(signature);
  };

  render() {
    return (
      <div>
        <button onClick={this.signMessage} />
      </div>
    );
  }
}
export default connect(state => {
  return {
    currentAccount: getSelectedAccount(state)
  };
})(App);

Selectors

Methods to get data from redux store.

  • getAccount(state, accountID) Return the corresponding account
  • getSelectedAccount(state) Return the selected account
  • getAccounts(state) Return all available accounts

Action creators

These functions are redux action creators. You need to dispatch the result to store.

  • selectAccount(accountID, type) Change Selected Account
  • unlockBrowserWalletAccount(accountID, password) Unlock a browser local wallet
  • showWalletModal() Show the wallets modal
  • hideWalletModal() Hide the wallets modal

Account functions

When we get an account from redux store, we can call some functions of account.wallet object.

Send Transaction (eth_sendTransaction)

/**
 *  Draft transaction
 */
const tx = {
  from: "0xbc28ea04101f03ea7a94c1379bc3ab32e65e62d3",
  to: "0x0000000000000000000000000000000000000000",
  nonce: 1,
  gas: 100000,
  value: "0x0",
  data: "0x0"
};

/**
 *  Send transaction
 */
const txId = await wallet.sendTransaction(tx);

Sign Personal Message (personal_sign)

/**
 *  Draft Message Parameters
 */
const msgParams = [
  "HYDRO-AUTHENTICATION" //message
];

/**
 *  Sign personal message
 */
const signature = await wallet.signPersonalMessage(msgParams);

Send Custom Request

/**
 *  Draft Custom Request
 */
const customRequest = [
  "eth_getTransactionReceipt", //method
  ["0x452817c981809fb7fab716dc84114b97c9ad2542c72fb9ed2c64d79e1bddb937"] //params
];

/**
 *  Send Custom Request
 */
const customResponse = await wallet.sendCustomRequest(customRequest);
