Callables.with_hashed_signature()

with_hashed_signature(signature_hash: int) → Callables

Adds a filter to get callables having specified selector (4 bytes of signature hash). Returns a filtered Callables child object. This method can be called on all Callables child classes: Functions and Modifiers.

Functions Example

from glider import *

def query():
  # Retrieve the functions that have 0x70a08231 as selector
  functions = Functions().with_hashed_signature(0x70a08231).exec(100)

  # Return the first five functions
  return functions[0:5]

Output:

[
    {
        "contract": "0x798AcB51D8FBc97328835eE2027047a8B54533AD",
        "contract_name": "IERC721",
        "sol_function": "function balanceOf(address owner) external view returns (uint256 balance);"
    },
    {

Modifiers Example

from glider import *

def query():
  # Retrieve the modifiers that have 0x2ddb862d as their selector
  modifiers = Modifiers().with_hashed_signature(0x2ddb862d).exec(100)

  # Return the first five modifiers
  return modifiers[0:5]
