Overview

This node interacts with the QuickNode API to retrieve the token balance of a specified Ethereum address for a given token contract. It is useful for blockchain developers, analysts, or applications that need to monitor or display token balances on the Ethereum network. For example, it can be used in wallet applications to show users their token holdings or in automated scripts to track token balances for multiple addresses.

Use Case Examples

1. Retrieve the token balance of an Ethereum address for a specific ERC-20 token contract.
2. Monitor token balances for addresses in a portfolio management tool.

Properties

Output

JSON

• resource - The resource type, here it is 'token'.
• operation - The operation performed, here it is 'getTokenBalance'.
• result - The raw result returned from the QuickNode API call, typically the token balance in hexadecimal format.
• timestamp - The timestamp when the data was retrieved.

Dependencies

• QuickNode API endpoint URL credential

Troubleshooting

• Ensure the Ethereum address and contract address are correctly formatted and valid hexadecimal strings starting with '0x'.
• If the QuickNode API returns an error, check the API endpoint URL and credentials for correctness and validity.
• Invalid JSON or malformed parameters will cause the node to throw errors; verify input parameters carefully.
