Overview

This node interacts with the Infura blockchain API to retrieve the current gas price on the Ethereum network. It is useful for scenarios where you need to estimate transaction costs or optimize transaction fees based on the current network conditions. For example, a user can use this node to fetch the latest gas price before sending a transaction to ensure it is processed promptly without overpaying.

Use Case Examples

1. Fetching the current gas price to display in a dashboard for Ethereum transaction fees.
2. Using the gas price data to dynamically set transaction fees in a smart contract interaction workflow.

Output

JSON

• gasPriceWei - Current gas price in wei (hexadecimal string)
• gasPriceGwei - Current gas price converted to Gwei (decimal number)
• metadata
  • network - The Ethereum network used (e.g., mainnet, rinkeby)
  • operation - The operation performed, here 'getGasPrice'
  • timestamp - Timestamp when the data was retrieved
  • infura_endpoint - The Infura API endpoint used for the request
  • raw_response - The raw response data from the Infura API

Dependencies

• Infura API credentials including network, project ID, and optionally project secret

Troubleshooting

• Ensure that the Infura API credentials are correctly configured and valid, including the network and project ID.
• If the node throws an error about unknown operation, verify that the operation parameter is set to 'getGasPrice'.
• If the response is empty or malformed, check network connectivity and Infura service status.
