Overview

This node interacts with blockchain networks via QuickNode RPC endpoints to retrieve the chain ID of the connected blockchain network. It is useful for identifying the specific blockchain network (e.g., Ethereum mainnet, testnets) you are working with, which is essential for ensuring transactions and interactions are conducted on the correct chain.

Use Case Examples

1. Use this node to verify the chain ID before sending transactions to avoid errors caused by interacting with the wrong blockchain network.
2. Retrieve the chain ID to dynamically configure other blockchain-related operations or smart contract interactions in your workflow.

Output

JSON

• resource - The resource type, here it is 'blockchain'.
• operation - The operation performed, here it is 'getChainId'.
• result - The raw chain ID result from the blockchain RPC call.
• timestamp - The ISO timestamp when the data was retrieved.
• chainId - The chain ID as an integer.
• chainIdHex - The chain ID in hexadecimal format.

Dependencies

• QuickNode RPC endpoint URL credential required for API access.

Troubleshooting

• Ensure the QuickNode API credential is correctly configured with a valid endpoint URL.
• If the node throws an error related to the API response, check the network connectivity and the validity of the RPC endpoint.
• Invalid or missing credentials will cause authentication errors.
