## Overview

The WIA DeFi Standard defines universal data formats for decentralized finance protocols, ensuring interoperability across AMMs, lending platforms, yield aggregators, and governance systems. This specification supports Ethereum, BSC, Polygon, Arbitrum, Optimism, and other EVM-compatible chains.

### Key Principles

- **Protocol Agnostic**: Works with Uniswap, Aave, Compound, Curve, Balancer, and others
- **Chain Neutral**: Support for multi-chain DeFi ecosystems
- **Composability**: Enable money lego strategies
- **Real-time**: Support for live TVL, APY, and price data
- **Security**: Built-in validation and audit trails

### Philosophy: 弘益人間 (Hongik Ingan)

> "Benefit All Humanity"

The WIA DeFi Standard democratizes access to decentralized finance by creating universal standards that enable seamless integration, reduce technical barriers, and promote financial inclusion globally.

## Validation Rules

### Pool Validation

```javascript
function validatePool(pool) {
  // Required fields
  if (!pool.version || !pool.standard || !pool.poolId) {
    throw new Error('Missing required fields');
  }

  // Standard version
  if (pool.standard !== 'WIA-FIN-006') {
    throw new Error('Invalid standard');
  }

  // Token validation
  if (!Array.isArray(pool.tokens) || pool.tokens.length < 2) {
    throw new Error('Pool must have at least 2 tokens');
  }

  // TVL must be positive
  if (pool.metrics.tvl <= 0) {
    throw new Error('TVL must be positive');
  }

  // Fee rate must be between 0 and 1
  if (pool.metrics.feeRate < 0 || pool.metrics.feeRate > 1) {
    throw new Error('Invalid fee rate');
  }

  return true;
}
```

### Health Factor Calculation

```javascript
function calculateHealthFactor(position) {
  const totalCollateralETH = position.totalCollateralUSD / ethPrice;
  const totalBorrowETH = position.totalBorrowedUSD / ethPrice;
  const avgLiquidationThreshold = position.liquidationThreshold;

  const healthFactor = (totalCollateralETH * avgLiquidationThreshold) / totalBorrowETH;

  return healthFactor;
}
```

### Impermanent Loss Calculation

```javascript
function calculateImpermanentLoss(priceRatio) {
  // IL = 2 * sqrt(priceRatio) / (1 + priceRatio) - 1
  const il = 2 * Math.sqrt(priceRatio) / (1 + priceRatio) - 1;
  return il * 100; // Return as percentage
}

// Example:
// If ETH price doubles (priceRatio = 2):
// IL = 2 * sqrt(2) / (1 + 2) - 1 = -5.72%
```
