Fetches real Aave V3 APY data (currently showing 5.13% for WAVAX)
Simulates subnet yields with realistic 2-6% bonuses over C-Chain rates
Calculates optimized cross-chain yields automatically
Updates every 30 seconds for market-responsive data

2. Cross-Chain Yield Comparison

Comprehensive comparison tool showing yield differences across chains:

C-Chain (Aave V3) yields with green indicators
Subnet yields with blue indicators
Yield differences (up to +3.78% identified)
Risk assessment (Low/Medium/High)
Optimal chain recommendations

3. WAVAX Deposit Functionality

Allows users to deposit WAVAX into Uniswap V2 liquidity pools:

Integrates with Trader Joe (Uniswap V2 fork) on Fuji
Two-step process: Approve WAVAX → Deposit to pool
Creates WAVAX/AVAX liquidity pair
Includes slippage protection (1%, 2%, 5% options)

4. Portfolio Management

Tracks user positions and performance across protocols:

Real-time token balance display
Yield performance tracking
Total portfolio value calculation
Easy rebalancing decisions

🔧 Technical Implementation

Core Components Architecture

YieldDataCard Component

// Component receives a token address as prop
const YieldDataCard: React.FC<YieldDataCardProps> = ({ tokenAddress }) => {
  // Gets data from Web3Context (global state)
  const { tokenYieldData, updateAaveData, isConnected, chainId, refreshTokenData, provider } = useWeb3();
  
  // Local state for subnet data and loading states
  const [subnetData, setSubnetData] = useState<SubnetYieldData | null>(null);
  const [isLoadingSubnet, setIsLoadingSubnet] = useState(false);

Button Functionality:

Refresh Button: Calls refreshTokenData() to fetch latest yield data from contracts
Update Cross-Chain Button: Triggers updateAaveData() to update on-chain Aave data
Request Subnet Data Button: Uses AWM to request fresh subnet yield information

WAVAXDepositCard Component

const WAVAXDepositCard: React.FC = () => {
  // Initialize Uniswap service when provider is available
  useEffect(() => {
    if (provider && chainId === 43113) {
      const service = new UniswapDepositService(provider);
      setDepositService(service);
    }
  }, [provider, chainId]);

Button Functionality:

Approve Button:

const handleApprove = async () => {
  setIsApproving(true);
  try {
    // Calls ERC20 approve function on WAVAX contract
    const txHash = await depositService.approveWAVAX(depositAmount);
    toast.success('WAVAX approved successfully!');
    setIsApproved(true);
  } catch (error) {
    toast.error(`Approval failed: ${error.message}`);
  } finally {
    setIsApproving(false);
  }
};

Deposit Button:

const handleDeposit = async () => {
  setIsDepositing(true);
  try {
    // Calls Uniswap V2 Router addLiquidityETH function
    const result = await depositService.depositWAVAX(depositAmount, slippageTolerance);
    if (result.success) {
      toast.success('WAVAX deposited successfully!');
      // Reset form and refresh balance
      setDepositAmount('');
      await loadWAVAXBalance();
    }
  } catch (error) {
    toast.error(`Deposit failed: ${error.message}`);
  } finally {
    setIsDepositing(false);
  }
};

Service Layer Architecture

Web3Context (Global State Management)

// Connects to MetaMask and initializes contracts
const connectWallet = async () => {
  const browserProvider = new BrowserProvider(window.ethereum);
  await browserProvider.send('eth_requestAccounts', []);
  const accounts = await browserProvider.listAccounts();
  setAccount(accounts[0].address);
  setIsConnected(true);
  setupContract(browserProvider);
};

// Refreshes token yield data from contracts
const refreshTokenData = async (tokenAddress?: string) => {
  const tokensToRefresh = tokenAddress ? [tokenAddress] : supportedTokens;
  for (const token of tokensToRefresh) {
    try {
      // Primary: Try comprehensive data method
      const [apyBps, tvl, liquidityIndex, lastUpdate] = await yieldHubContract.getAaveDetails(token);
      const optimizedAPY = await yieldHubContract.calculateOptimizedAPY(token);
    } catch (error) {
      // Fallback: Use individual methods
      const apyBps = await yieldHubContract.getAaveAPY(token);
      const tvl = await yieldHubContract.getAaveTVL(token);
    }
  }
};

Auto-Refresh Mechanism:

useEffect(() => {
  if (!autoRefresh || !yieldHubContract) return;
  const interval = setInterval(async () => {
    await refreshTokenData(); // Refresh every 30 seconds
  }, 30000);
  return () => clearInterval(interval);
}, [autoRefresh, yieldHubContract]);

SubnetService (Cross-Chain Data)

// Gets comprehensive yield data including subnet information
async getComprehensiveYieldData(tokenAddress: string): Promise<SubnetYieldData | null> {
  try {
    // Try to get real Aave data from YieldHub
    const [apyBps, tvl, liquidityIndex, lastUpdate] = await this.yieldHubContract.getAaveDetails(tokenAddress);
    const optimizedAPY = await this.yieldHubContract.calculateOptimizedAPY(tokenAddress);
    
    // Get simulated subnet data (fallback until AWM is fully deployed)
    const simulatedSubnetData = await this.getSimulatedSubnetData(tokenAddress);
    
    return {
      tokenAddress,
      tokenSymbol: tokenInfo.symbol,
      subnetAPY: simulatedSubnetData.subnetAPY,
      aaveAPY: apyBps,
      optimizedAPY: optimizedAPY,
      // ... other properties
    };
  } catch (error) {
    // Fallback to fully simulated data
    return await this.getSimulatedSubnetData(tokenAddress);
  }
}

UniswapDepositService (DeFi Integration)

// Deposits WAVAX into Uniswap V2 liquidity pool
async depositWAVAX(amount: string, slippageTolerance: number = 2): Promise<DepositResult> {
  const signer = await this.provider.getSigner();
  const contractWithSigner = this.routerContract.connect(signer);
  
  const amountWei = ethers.parseEther(amount);
  const avaxAmountWei = ethers.parseEther(amount); // 1:1 ratio
  
  // Calculate minimum amounts with slippage protection
  const slippageMultiplier = (100 - slippageTolerance) / 100;
  const minTokenAmount = BigInt(Math.floor(Number(amountWei) * slippageMultiplier));
  const minAVAXAmount = BigInt(Math.floor(Number(avaxAmountWei) * slippageMultiplier));
  
  // Execute the deposit transaction
  const tx = await contractWithSigner.addLiquidityETH(
    UNISWAP_V2_CONFIG.WAVAX_ADDRESS,
    amountWei,                    // WAVAX amount
    minTokenAmount,               // Minimum WAVAX (slippage protection)
    minAVAXAmount,               // Minimum AVAX (slippage protection)
    await signer.getAddress(),    // LP tokens recipient
    deadline,                     // Transaction deadline
    { value: avaxAmountWei }     // AVAX to pair with WAVAX
  );
  
  return { success: true, transactionHash: tx.hash };
}

Smart Contract Integration

Primary data fetching method:

const [apyBps, tvl, liquidityIndex, lastUpdate] = await yieldHubContract.getAaveDetails(tokenAddress);

// Fallback for reliability
if (primaryMethodFails) {
  const apyBps = await yieldHubContract.getAaveAPY(tokenAddress);
  const tvl = await yieldHubContract.getAaveTVL(tokenAddress);
}

Cross-Chain Messaging (AWM):

// Request subnet yield data via AWM
const requestId = await yieldHubContract.requestSubnetYield(tokenAddress, { value: fee });

// Track request status
const status = await subnetService.getRequestStatus(requestId);
