1. Lending Operations
   * USDC deposits
   * Yield generation
   * APY tracking
   * Account management
2. Account Features
   * Real-time APY
   * Interest tracking
   * Total value monitoring
   * Protocol settings

Copy

```typescript
// Lend USDC
const signature = await agent.methods.lendAssets(100); // Lend 100 USDC

// Get account details
const details: LuloAccountDetailsResponse = {
  totalValue: 100.5,
  interestEarned: 0.5,
  realtimeApy: 5.2,
  settings: {
    owner: "wallet-address",
    allowedProtocols: null,
    homebase: null,
    minimumRate: "4.8"
  }
};
```

Copy

```
"Lend 100 USDC to earn yield"

"Deposit USDC into Lulo for interest"

"Start earning yield on my USDC"

"Put my USDC to work in Lulo"
```

Copy

```
// Basic lending
{
  "amount": 100
}

// Alternative format
"100"  // Direct amount input
```

Copy

```typescript
{
  status: "success",
  message: "Asset lent successfully",
  transaction: "5UfgJ5vVZxUx...",
  amount: 100
}
```

Copy

```typescript
interface LuloAccountDetailsResponse {
  totalValue: number;        // Total value in USDC
  interestEarned: number;    // Total interest earned
  realtimeApy: number;       // Current APY
  settings: {
    owner: string;           // Wallet address
    allowedProtocols: string | null;
    homebase: string | null;
    minimumRate: string;     // Minimum acceptable APY
  }
}
```

Copy

```typescript
// Parameters
interface LendParams {
  amount: number;      // USDC amount
  symbol: string;      // Always "USDC"
  account: string;     // Wallet address
}

// Features
- Transaction versioning
- Blockhash handling
- Confirmation tracking
- Retry logic
```

Copy

```typescript
try {
  const signature = await agent.methods.lendAssets(amount);
} catch (error) {
  if (error.message.includes("insufficient funds")) {
    // Handle insufficient balance
  } else if (error.message.includes("slippage")) {
    // Handle price movement
  }
}
```
