## Features

-   **Transaction Building:** Create buy and sell transactions with pre-defined instruction discriminators.
-   **On-Chain Monitoring:** Subscribe to logs and account updates via websockets.
-   **Transaction Analysis:** Decode and analyze transactions using a provided IDL.
-   **Bonding Curve Analysis:** Parse on-chain bonding curve state and compute token prices.
-   **Token Operations:** Retrieve token information, prices, holders, transactions, and liquidity.
-   **User Operations:** Track user's created tokens, trading history, and liquidity positions.

## Installation

Install the SDK using pip:

```bash
pip install pumpfun-sdk
```

    )

if __name__ == "__main__":
    asyncio.run(monitor_program_activity())

### Transaction Analysis

This example demonstrates how to decode a transaction using a provided IDL file. The SDK now uses `load_pump_idl` from `pumpfun_sdk.idl` for loading IDL definitions.

```python
#!/usr/bin/env python
"""
Transaction Analysis Example for pumpfun_sdk.

This script demonstrates how to:
- Load a raw transaction from a file.
- Decode the transaction using a provided IDL.
- Print the decoded instructions.
"""

import asyncio
from pumpfun_sdk.utils import decode_transaction_from_file
from pumpfun_sdk.idl import load_pump_idl

async def analyze_transaction():
    # Replace these with actual file paths
    tx_file = "path/to/transaction.json"
    idl_file = "path/to/idl.json"

    print("=== Analyzing Transaction ===")
    try:
        # This function uses the custom IDL file if provided, otherwise falls back to the built-in Pump Fun IDL.
        await decode_transaction_from_file(tx_file, idl_file)
    except Exception as e:
        print(f"Error analyzing transaction: {e}")

if __name__ == "__main__":
    asyncio.run(analyze_transaction())
```
