Before you connect
Questions about Harmonyscan.
The practical details behind the request, access and result.
Does Harmonyscan MCP support Harmony One balances?
Yes, it lets your agent fetch the ONE balance for a single wallet or multiple addresses at once.
Can I use it to check my transaction status?
You can ask your agent to verify if a transaction was successful or check its receipt status using the network data.
How do I get contract source code?
Your agent can pull verified source code and ABIs directly from the Harmony One blockchain using the Connector.
Can it track HRC20 tokens?
Yes, it can list HRC20 token transfer events so you can track specific token movements.
Is there a way to see internal transactions?
This Connector can pull internal transactions, which are often missed by standard block explorers.
Does it provide real-time ONE prices?
Yes, your agent can pull the current market price and total supply for the ONE token.
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.
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.
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.
