Overview

This node interacts with blockchain networks via QuickNode RPC endpoints to retrieve the current gas price on the blockchain. It is useful for scenarios where you need to know the current transaction fee rate to estimate costs or optimize transaction timing. For example, a user can use this node to fetch the current gas price before sending a transaction to ensure they pay an appropriate fee.

Use Case Examples

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

Output

JSON

• resource - The resource type, here it is 'blockchain'.
• operation - The operation performed, here it is 'getGasPrice'.
• result - The raw gas price result from the blockchain in hexadecimal format.
• timestamp - The ISO timestamp when the data was retrieved.
• gasPriceWei - The gas price in wei (smallest unit of Ether).
• gasPriceGwei - The gas price converted to Gwei (1 Gwei = 10^9 wei), a more human-readable unit.

Dependencies

• Requires QuickNode API endpoint URL as credential for RPC calls.

Troubleshooting

• If the node returns an error indicating 'QuickNode API error', verify that the QuickNode API endpoint URL credential is correctly configured and active.
• If the gas price result is missing or malformed, ensure the blockchain network is reachable and the RPC endpoint supports the 'eth_gasPrice' method.
• Invalid JSON or network errors may occur if the QuickNode service is down or the network connection is unstable.
