This method requires appending /nanoreth to your HyperLiquid endpoint URL. Debug and Trace methods are not supported on /evm endpoints. Use /nanoreth instead of /evm to access debugging functionality.

Parameters

block

string

REQUIRED

The RLP encoded block

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

array

Array of transaction trace results with the following fields:

result

object

The trace result object for each transaction

type

string

The type of the call

from

string

The address the transaction is sent from

to

string

The address the transaction is directed to

value

string

The integer of the value sent with this transaction

gas

string

The integer of the gas provided for the transaction execution

gasUsed

string

The integer of the gas used

input

string

The data given at the time of input

output

string

The data which is returned as an output

error

string

(Optional) Error message if the transaction execution failed

revertReason

string

(Optional) Human-readable revert reason when transaction execution failed

calls

array

A list of sub-calls made during transaction execution

type

string

The type of call (CALL, STATICCALL, DELEGATECALL)

from

string

The address the call is sent from

to

string

The address the call is directed to

gas

string

The gas provided for the call execution

gasUsed

string

The gas used by the call

input

string

The call data

output

string

(Optional) The call output data

value

string

The value transferred in the call

error

string

(Optional) Error message if the call failed

calls
