# trace\_callMany

### Parameters

1. List of trace calls with the following parameters:
   1. `Object` - The transaction call object with the following:
      * `from`(optional): the address the transaction is sent from.
      * `to`(optional): the address the transaction is sent to.
      * `gas`(optional): Integer of the gas provided for the transaction execution. eth\_call consumes zero gas, but this parameter may be needed by some executions.
      * `gasPrice`(optional): Integer of the gasPrice used for each paid gas.
      * `value`(optional): Integer of the value sent with this transaction.
      * `data`(optional): Hash of the method signature and encoded parameters. For details see [Ethereum Contract ABI in the Solidity documentation](https://docs.soliditylang.org/en/latest/abi-spec.html).
   2. `Type` of trace - choose 1 of the following options:
      * `"trace"` - Provides an ordered trace of the instructions.
      * `"stateDiff"` - Provides information detailing all altered portions of the Ethereum state made due to the execution of the transaction.
      * `"vmTrace"` - Provides a full trace of the VM’s state throughout the execution of the transaction, including for any subcalls.
2. `Quantity` or `tag` - choose 1 of the following options:
   * A hexadecimal block number.
   * `"earliest"` - the earliest/genesis block.
   * `"latest"` - the latest mined block.
   * `"safe"` - the latest safe head block.
   * `"finalized"` - the latest finalized block.
   * `"pending"` - the pending state/transactions.
