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

object

object

The transaction call object with the following fields:

from

string

The initiating Ethereum address for the transfer, which will be null if not applicable

to

string

The address the transaction is directed to, which will be null if not applicable

gas

integer

The integer of the gas provided for the transaction execution

gasPrice

integer

The integer of the gasPrice used for each paid gas

value

integer

The integer of the value sent with this transaction

data

string

The hash of the method signature and encoded parameters

blockReference

string

The block number in hexadecimal format, the block hash, or tags. The supported tag values include earliest for the earliest/genesis block, latest for the latest mined block, pending for the pending state/transactions, safe for the most recent secure block, and finalized for the most recent secure block accepted by more than 2/3 of validators

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

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

A list of sub-calls, if any

value

The integer of the value sent with this transaction

type

The type of the call
