==== Dependence on predictable environment variable ==== Type: Warning Contract: WeakRandom Function name: _function_0xe9874106 PC address: 1285 In the function `'_function_0xe9874106'` the following predictable state variables are used to determine Ether recipient: - block.coinbase -------------------- In file: /inputs/weak_random.sol:47 winningAddress.transfer(prize) -------------------- ==== Ether send ==== Type: Warning Contract: WeakRandom Function name: _function_0xe9874106 PC address: 1285 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'. -------------------- In file: /inputs/weak_random.sol:47 winningAddress.transfer(prize) -------------------- ==== Exception state ==== Type: Informational Contract: WeakRandom Function name: fallback PC address: 356 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. -------------------- In file: /inputs/weak_random.sol:11 prize / totalTickets -------------------- ==== Exception state ==== Type: Informational Contract: WeakRandom Function name: _function_0xe9874106 PC address: 146 A reachable exception (opcode 0xfe) has been detected.
