# Optimize DeFi Yield

Comprehensive DeFi yield optimization across protocols with APY tracking, risk assessment, and automated strategy recommendations.

## Usage

When optimizing DeFi yield, implement comprehensive analysis across protocols:

### Required Parameters
- **Capital**: Amount to deploy
- **Risk Tolerance**: low, medium, high
- **Chains**: ethereum, bsc, polygon, arbitrum, all
- **Duration**: Days to farm (7, 30, 90, 365)
- **Strategy**: stable, balanced, aggressive

## Implementation

### 1. DeFi Yield Optimizer

```javascript
class DeFiYieldOptimizer {
    constructor() {
        this.protocols = {
            ethereum: {
                aave: { api: 'https://api.aave.com/v3', type: 'lending' },

### 3. Auto-Compound Calculator

```javascript
class AutoCompoundCalculator {
    calculateOptimalFrequency(params) {
        const {
            principal,
            apy,
            gasCost,
            duration
        } = params;

        const frequencies = [1, 7, 14, 30, 90, 365];
        const results = [];

        for (const freq of frequencies) {
            const compoundsPerYear = 365 / freq;
            const gasPerYear = compoundsPerYear * gasCost;
            const apr = apy / 100;

            // Calculate compound interest with gas costs
            const finalValue = principal * Math.pow(1 + apr / compoundsPerYear, compoundsPerYear * duration / 365) - gasPerYear;
            const netReturn = finalValue - principal;
            const netAPY = (netReturn / principal) * (365 / duration) * 100;

            results.push({
                frequency: freq,
                compounds: Math.floor(duration / freq),
                gasCost: gasPerYear * duration / 365,
                finalValue,
                netAPY,
                profit: netReturn
            });
        }

        return results.sort((a, b) => b.netAPY - a.netAPY)[0];
    }
}
```

## Error Handling

```javascript
try {
    const optimizer = new DeFiYieldOptimizer();
    const result = await optimizer.optimizeYield({
        capital: 10000,
        riskTolerance: 'medium',
        chains: ['ethereum', 'polygon'],
        duration: 30,
        strategy: 'balanced'
    });

    const display = new YieldDisplay();
    console.log(display.displayOptimization(result));

} catch (error) {
    console.error('Yield optimization failed:', error);
}
```

This command provides comprehensive DeFi yield optimization with risk assessment and portfolio allocation strategies.
