Gas Price Monitoring Service

Create a Python service that monitors and reports current Ethereum gas prices in multiple units.

Requirements

Your service should provide functionality to:

1. Connect to an Ethereum node and retrieve the current gas price
2. Convert the gas price from Wei to both Gwei and Ether
3. For EIP-1559 compatible networks, retrieve the recommended priority fee for the next block
4. Return all pricing information in a structured format

Implementation Details

Create a Python module that exports a function get_gas_report() which:

• Returns a dictionary containing:
  • gas_price_wei: The current gas price in Wei (as an integer)
  • gas_price_gwei: The current gas price in Gwei (as a float)
  • gas_price_ether: The current gas price in Ether (as a float)
  • priority_fee_gwei: The recommended priority fee in Gwei (as a float, or None if not available)

The function should handle connection to an Ethereum node provider (you may use any provider configuration that works for testing).

Test Cases

• Calling get_gas_report() returns a dictionary with all required keys @test
• The gas_price_wei value is a positive integer @test
• The gas_price_gwei and gas_price_ether conversions are mathematically correct relative to gas_price_wei @test
• The function successfully retrieves priority fee information when available @test

API

def get_gas_report() -> dict:
    """
    Retrieve current gas pricing information from the Ethereum network.

    Returns:
        dict: A dictionary containing:
            - gas_price_wei (int): Current gas price in Wei
            - gas_price_gwei (float): Current gas price in Gwei
            - gas_price_ether (float): Current gas price in Ether
            - priority_fee_gwei (float or None): Recommended priority fee in Gwei
    """
    pass
