# debug\_traceCall

Returns the number of possible tracing results by executing an eth call within the context of the given block execution.

This method will use `80` [Compute Units](https://docs.validationcloud.io/v1/about/billing).

***

## **Parameters**

`object` - Object - The transaction call object with the following fields:

* `from` - String - The address the transaction is sent from
* `to` - String - <mark style="color:red;">Required</mark> - The address the transaction is directed to
* `gas` - Integer - The integer of the gas provided for the transaction execution
* `gasPrice` - Integer - The integer of the gasPrice used for paid gas
* `value` - Integer - The integer of the value sent with this transaction
* `data` - String - The has of the method signature and encoded parameters

`blockReference` - String - <mark style="color:red;">Required</mark> - The block number in hexadecimal format, the block hash, or tags: `"earliest"`, `"latest"` or `"pending"`.

`object` - Object (Optional) - The tracer object with the following fields:

* `tracer` - String - The type of tracer, options are: `callTracer` or `prestateTracer`.
  * `callTracer` - String - The callTracer keeps track of all call frames, including depth - calls, that are made during a transaction.
  * `prestateTracer` - String - The prestateTracer replays the transaction and tracks every part of state that occurred during the transaction.
* `tracerConfig` - Object (Optional) - The object to specify the configurations of the tracer.
  * `onlyTopCall` - Boolean - When set to true, this will only trace the primary (top-level) call and not any sub-calls. It eliminates the additional processing for each call frame.

## **Returns**

`result` - An array of transaction objects for that block, each containing:

* `txHash` - The transaction hash of the transaction
* `result` - An object containing detailed information about the traced transaction
  * `beforeEVMTransfers` - An array representing EVM transfers that occurred before the execution of the transaction
    * `purpose` - (Optional) The purpose of the EVM transfer
    * `from` - (Optional) The Ethereum address initiating the transfer
    * `to` - (Optional) The Ethereum address receiving the transfer
    * `value` - (Optional) The value of the transfer, specified in hexadecimal format (Wei)
  * `afterEVMTransfers` - An array representing EVM transfers that occurred after the execution of the transaction
    * Optional fields are the same as `beforeEVMTransfers` above
  * `from` - The address the transaction is sent from.
  * `gas` - The integer of the gas provided for the transaction execution.
  * `gasUsed` - The integer of the gas used.
  * `to` - The address the transaction is directed to.
  * `input` - The data given at the time of input.
  * `value` - The integer of the value sent with this transaction.
  * `type` - The type of call.
* `calls` - A list of sub-calls.
