Dependence on predictable environment variable

  • Type: Warning
  • Contract: Unknown
  • Function name: _function_0xe9874106
  • PC address: 1285

Description

In the function '_function_0xe9874106' the following predictable state variables are used to determine Ether recipient:

  • block.coinbase

Ether send

  • Type: Warning
  • Contract: Unknown
  • Function name: _function_0xe9874106
  • PC address: 1285

Description

In the function '_function_0xe9874106' a non-zero amount of Ether is sent to an address taken from storage slot 0. There is a check on storage index 0. This storage slot can be written to by calling the function 'fallback'.

There is a check on storage index 1. This storage slot can be written to by calling the function 'fallback'. There is a check on storage index 1. This storage slot can be written to by calling the function 'fallback'.

Exception state

  • Type: Informational
  • Contract: Unknown
  • Function name: fallback
  • PC address: 356

Description

A reachable exception (opcode 0xfe) has been detected. This can be caused by type errors, division by zero, out-of-bounds array access, or assert violations. This is acceptable in most situations. Note however that assert() should only be used to check invariants. Use require() for regular input checking.

Integer Overflow

  • Type: Warning
  • Contract: Unknown
  • Function name: _function_0xe9874106
  • PC address: 1216

Description

A possible integer overflow exists in the function _function_0xe9874106. The addition may result in a value higher than the maximum representable integer.
