# debug\_traceBlockByNumber

Returns the possible tracing result number by executing all transactions in the block specified by the block number with a tracer.

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

***

## **Parameters**

`blockNumber` - String - <mark style="color:red;">Required</mark>  - The block number as a string in hexadecimal format.

`object` - Object - <mark style="color:red;">Required</mark>  - 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 transactions for that block, each containing:

* `txHash` - The transaction hash of the transaction
* `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.
