import { polygon } from 'viem/chains';

const client = createVarlaClient({
  chain: polygon,
  transport: http(),
});

// Read current pool state
const pool = await client.readPoolSnapshot();
console.log('Supply APY:', pool.supplyAPY);
console.log('Borrow APY:', pool.borrowAPY);
console.log('Utilization:', pool.utilization);

// Deposit collateral (requires wallet)

const varla = client.withWallet(wallet);

await varla.deposit(tokenId, amount);
await varla.borrow(parseUnits('1000', 6)); // Borrow 1000 USDC
