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 40 Compute Units.

---

Parameters

blockNumber - String - Required - The block number as a string in hexadecimal format.

object - Object - Required - The tracer object with the following fields:

• tracer - String - The type of tracer, options are: callTracer ,prestateTracer or flatCallTracer.

  • 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 trackers every part of state that occurred during the transaction.

  • flatCallTracer - String - The flatCallTracer is a specific type of tracer that provides a flattened view of all calls made during transaction execution. It offers a simplified output compared to the standard callTracer, making it easier to analyze complex transactions.

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.
