Environment Variables

# .env.local
NEXT_PUBLIC_STELLAR_NETWORK=mainnet
NEXT_PUBLIC_RPC_URL=https://soroban-rpc.stellar.org
TELEGRAM_BOT_TOKEN=your_bot_token
SMTP_CONFIG=your_email_config

🧠 How It Works

1. Connect Wallet

Support for Freighter and Albedo wallets. Users connect to view their Blend positions across all pools.

2. Position Monitoring

const pool = await Pool.load({ rpcUrl, passphrase }, POOL_ID);
const user = await pool.loadUser(publicKey);
const positions = await user.getPositions();

3. Health Factor Analysis

const calculateHealthFactor = (collateral: bigint, debt: bigint) => {
  if (debt === 0n) return Infinity;
  return Number((collateral * 100n) / debt);
};

Risk Classification:

• 🟢 Healthy: HF > 150%
• 🟡 Warning: 120% < HF ≤ 150%
• 🔴 Critical: HF ≤ 120%

4. Alert System

// Telegram integration
bot.sendMessage(chatId, "🚨 Liquidation risk detected!");
