What You've Accomplished

Throughout this guide series, you've learned how to:

1. Create Smart Contracts:

   • Master Solidity fundamentals and develop contracts optimized for the XOS environment
     (Reference: Creating Smart Contracts)

2. Deploy Smart Contracts:

   • Use development tools like Remix and Hardhat to deploy your contracts to the XOS network (Reference: Deploying Smart Contracts)

3. Verify Smart Contracts:

   • Ensure transparency and build user confidence by verifying your contract source code (Reference: Contract Verification)

4. Interact with Smart Contracts:

   • Execute contract functions and integrate with applications using web3 libraries (Reference: Interacting with Smart Contracts)

Advanced Development Paths

Now that you've mastered the basics, consider exploring these advanced topics:

1. Token Development:

   • Implement ERC-20 fungible tokens for creating currencies or utility tokens
   • Build ERC-721 non-fungible tokens for digital collectibles and unique assets

2. Financial Applications:

   • Create decentralized finance solutions including lending protocols, exchanges, and yield optimization tools
   • Implement secure financial contracts with advanced security patterns

3. AI and Smart Contract Integration:

   • Leverage machine learning for contract optimization and automated testing
   • Develop oracle systems for bringing off-chain data to your contracts

Building a Complete Frontend Application

To create a full-featured decentralized application, you'll need to develop a frontend that connects to your smart contracts. Below is a guide to creating a modern web application using Next.js and TypeScript that integrates with the XOS network.

Project Setup

1. Initialize Your Project

Start with a modern development template:

npx create-next-app@latest xos-dapp --typescript
cd xos-dapp

2. Install Dependencies

Add the necessary blockchain integration libraries:

npm install ethers wagmi viem @web3modal/react @web3modal/ethereum

3. Configure Environment Variables

Create a .env.local file with your configuration:

NEXT_PUBLIC_WALLET_CONNECT_ID=your_project_id_here
NEXT_PUBLIC_ALCHEMY_API_KEY=your_api_key_here

4. Set Up XOS Network Configuration

Create a network configuration file at src/config/networks.ts:

import { Chain } from 'wagmi'

export const xosNetwork: Chain = {
  id: 1267,
  name: 'XOS Network',
  network: 'xos',
  nativeCurrency: {
    decimals: 18,
    name: 'XOS',
    symbol: 'XOS',
  },
  rpcUrls: {
    public: { http: ['https://testnet-rpc.x.ink'] },
    default: { http: ['https://testnet-rpc.x.ink'] },
  },
  blockExplorers: {
    default: { name: 'XOScan', url: 'https://xoscan.io' },
  },
}

5. Launch Development Server

Start your application with:

npm run dev

Access your application at http://localhost:3000 (or your configured port)

Key Frontend Components

Your dApp will need several essential components for blockchain interaction:

Wallet Connection Component

import { ConnectButton } from '@rainbow-me/rainbowkit';

export function WalletConnect() {
  return (
    <div className="wallet-connect-container">
      <ConnectButton label="Connect Wallet" />
    </div>
  );
}

Contract Interaction Component

import { useState } from 'react';
import { useContractRead, useContractWrite } from 'wagmi';
import { contractABI } from '../config/contract-abi';

export function ContractInteraction({ contractAddress }) {
  const [inputValue, setInputValue] = useState('');
  
  const { data: storedValue } = useContractRead({
    address: contractAddress,
    abi: contractABI,
    functionName: 'getValue',
  });
  
  const { write: setValue } = useContractWrite({
    address: contractAddress,
    abi: contractABI,
    functionName: 'setValue',
  });
  
  return (
    <div className="contract-interaction">
      <h2>Current Value: {storedValue?.toString()}</h2>
      <input
        value={inputValue}
        onChange={(e) => setInputValue(e.target.value)}
        placeholder="Enter new value"
      />
      <button onClick={() => setValue({ args: [inputValue] })}>
        Update Value
      </button>
    </div>
  );
}
