Parameters

blockHash

string

REQUIRED

The hash of the block to be traced

object

object

REQUIRED

The tracer object with the following fields:

tracer

string

The type of tracer. It could be callTracer or prestateTracer

callTracer

string

The calltracer keeps track of all call frames, including depth 0 calls, that are made during a transaction

prestateTracer

string

The prestateTracer replays the transaction and tracks every part of state that occured during the transaction

tracerConfig

object

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

The result object which contains the following fields:

txHash

The hash of the transaction being traced

result

An object containing detailed information about the traced 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

output

(Optional) The data which is returned as an output

error

(Optional) The type of error, if any

revertReason

(Optional) The type Solidity revert reason, if any

calls

An array containing information about internal calls made during the transaction. It can also have subcalls

from

The address making the call

gas

The gas limit specified for the call

gasUsed

The amount of gas used during the call

to

The address being called

input

The input data for the call

output

(Optional) The output data of the call

error

(Optional) The type of error, if any

revertReason

(Optional) The type Solidity revert reason, if any

value

The value (in Wei) sent with the call

type

The type of call (e.g., CALL or STATICCALL)

calls

(Optional) The sub-calls associated with the call

value

The integer of the value sent with this transaction

type

The type of the call
