Overview

This node interacts with blockchain networks via QuickNode RPC endpoints to estimate the gas required for a given transaction. It is useful for developers and users who want to predict the gas cost before sending a transaction on the Ethereum blockchain or compatible networks. For example, before executing a smart contract call or token transfer, users can estimate the gas to ensure they provide enough gas for the transaction to be processed successfully.

Use Case Examples

1. Estimating gas for a token transfer transaction to ensure sufficient gas is provided.
2. Estimating gas for a smart contract interaction to avoid transaction failure due to out-of-gas errors.

Properties

Output

JSON

• resource - The resource type, here it is 'blockchain'.
• operation - The operation performed, here it is 'estimateGas'.
• result - The raw result returned from the QuickNode API.
• timestamp - The timestamp when the data was retrieved.
• estimatedGas - The estimated gas amount required for the transaction, parsed as an integer.
• estimatedGasHex - The estimated gas amount in hexadecimal format.

Dependencies

• QuickNode API endpoint URL credential

Troubleshooting

• Invalid JSON format in the Transaction Object input will cause an error. Ensure the JSON is correctly formatted.
• API errors from QuickNode will be surfaced with the error message from the API response.
• Network or connectivity issues may cause request failures; verify the QuickNode endpoint URL and network connection.
