This RPC method is included in the Free Trial with limited usage. Upgrade your plan to get full access and higher limits. Learn more on our pricing page.

Please note that all debug_trace methods can be used for blocks after 22207818, while arbtrace_ methods can be used on blocks prior to 22207816. Block 22207817 cannot be traced but is empty.

Parameters

blockHash

string

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, prestateTracer or stylusTracer

callTracer

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

prestateTracer

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

stylusTracer

The stylusTracer is specific to Arbitrum for tracing Stylus contracts

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

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

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)

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)

value

The integer of the value sent with this transaction

type

The type of the call
