data

string

The hash of the method signature and encoded parameters

nonce

string

The number of transactions made by the sender prior to this one

chainId

string

The chain ID of the network

accessList

array

A list of addresses and storage keys that the transaction plans to access

blockReference

string

REQUIRED

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

object

object

REQUIRED

The tracer object with the following fields:

tracer

string

The type of tracer. It could be callTracer or prestateTracer

callTracer

string

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
