Parameters

transactionHash

string

REQUIRED

The transaction hash that needs to be traced, encoded in hexadecimal format

object

object

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

timeout

string

A string of decimal integers that overrides the JavaScript-based tracing calls default timeout of 5 seconds

Returns

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

calls

An array containing information about internal calls made during the transaction

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

value

The value (in Wei) sent with the call

type

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

calls

The sub-calls associated with the call

value

The integer of the value sent with this transaction

type
