FAQ

Questions Harmonyscan owners ask.

  • 01

    Can I check the balance of multiple Harmony addresses at once?

    Yes! Use the get_balance_multi capability and provide a comma-separated list of addresses (up to 20). The agent will return the ONE balance for each address in a single response.

  • 02

    How do I verify if a specific transaction was successful or failed?

    You can use the get_status capability with the transaction hash. It returns a status code where '1' indicates success and '0' indicates failure, along with any available error messages.

  • 03

    Is it possible to retrieve the source code of a smart contract?

    Yes, provided the contract is verified on Harmonyscan. Use the get_source_code capability with the contract address to get the Solidity source code, compiler version, and optimization settings.
