## 🤖 Prompts

### 💬 Example Prompts for Claude, ChatGPT, or Other AI Assistants

These prompts demonstrate how to interact with the MCP server through natural language when integrated with AI assistants:

#### 💱 **Token Operations**

```
"What's my XPL balance?"

"Send 5 XPL to 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb9"

"Check the status of transaction 0x123...abc"

"Estimate gas for sending 100 XPL to this address"
```

#### 📊 **Network Analysis**

```
"Show me the current gas price on Plasma Network"

"Get the latest 5 blocks from the network"

"What's the current network status?"

"Show me network information including block height"
```

#### 💼 **Wallet Management**

```
"Get my wallet nonce and balance"

"Show all token balances in my wallet"

"Request testnet XPL from the faucet"

"Calculate the cost of a transaction with current gas prices"
```

#### 🔧 **Smart Contract Interaction**

```
"Get information about token at address 0x..."

"Send a custom transaction with data payload"

"Estimate gas for a contract interaction"

"Check if a transaction was successful"
```

### 🔧 Integration Tips for AI Assistants

When using these prompts with the MCP server:

1. **Always specify addresses** in full format (0x...)
2. **Use decimal amounts** for XPL (e.g., "10.5" not "10500000000000000000")
3. **Check gas prices** before large transactions
4. **Verify balances** before attempting transfers
5. **Monitor transaction status** after sending
