## 📖 Usage Examples

### Portfolio Analysis
```typescript
// Get wallet balance
const balance = await mcpClient.call('portfolio.getBalance', {
  address: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10',
  chain: 'ethereum'
});

// Get DeFi positions
const positions = await mcpClient.call('portfolio.getPositions', {
  address: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10'
});
```

### Strategy Proposal
```typescript
// DCA Event-Aware Strategy
const strategy = await mcpClient.call('strategy.propose', {
  intent: 'dca_event_aware',
  params: {
    asset: 'ETH',
    budgetUsd: 200,
    cadence: '2x/week',
    eventRules: {
      pauseOnUnlock: true,
      maxGasGwei: 25,
      boostOnDrawdownPct: 3
    }
  },
  address: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10'
});
```

### Transaction Execution
```typescript
// Simulate transaction
const simulation = await mcpClient.call('transaction.simulate', {
  intentId: 'dca_event_aware_123',
  txParams: {
    to: '0x1234...',
    value: '100000000000000000',
    gasLimit: '150000'
  }
});

// Execute if simulation passes
if (simulation.ok) {
  const execution = await mcpClient.call('transaction.execute', {
    intentId: 'dca_event_aware_123',
    txParams: simulation.txParams
  });
}
```
