  • Type: Warning
  • Contract: D
  • Function name: _function_0xeea4c864
  • PC address: 1038

Description

This contract executes a message call to an address provided as a function argument. Generally, it is not recommended to call user-supplied adresses using Solidity's call() construct. Note that attackers might leverage reentrancy attacks to exploit race conditions or manipulate this contract's state.
