Queries do not change the state of the smart contract or require network consensus. The information is returned from a single node processing the query. Query Signing Requirements
  • The client operator account’s private key (fee payer) is required to sign this query
Query Fees
  • Please see the transaction and query fees table for the base transaction fee
  • Please use the Hedera fee estimator to estimate your query fee cost
