    Class MirrorNodeContractCallQuery

    A query that simulates a contract function call using the Hedera Mirror Node. *

    • This query allows you to execute a read-only smart contract call without submitting a transaction
    • to the main network. It's useful for querying contract state or executing view/pure functions.
    • The simulation is performed against the state of the contract at a specific block height.

    Methods

    _fillEvmAddress

    • Parameters

      • client: Client<Channel, MirrorChannel>
      • OptionalrequestTimeout: number

        total timeout for the whole operation in milliseconds, every retry included; defaults to the client's mirror node HTTP retry policy

      Returns Promise<string>

    • POST /api/v1/contracts/call through the client's shared HTTP transport. Retry, backoff and timeouts follow the client's MirrorNodeHttpRetryPolicy (see Client.setMirrorNodeHttpConfig); the body is replayed byte for byte on a retry.

      Parameters

      • client: Client<Channel, MirrorChannel>
      • jsonPayload: object
      • OptionalrequestTimeout: number

        total timeout for the whole operation in milliseconds, every retry included; defaults to the retry policy's totalDeadline, which in turn defaults to client.requestTimeout

      Returns Promise<MirrorNodeResponse>

    • Parameters

      • sender: string

      Returns MirrorNodeContractCallQuery

      Set the 20-byte EVM address of the sender. This method must be used explicitly when working with accounts that have ECDSA keys with aliases, as their EVM addresses cannot be automatically derived and must be retrieved from the Mirror Node API. The EVM address can be filled using accountId.populateAccountEvmAddress(client)
