# Analysis results for test-filename.sol
## External Call To User-Supplied Address
- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `thisisfine()`
- PC address: 661
- Estimated Gas Usage: 643 - 1254
### Description
A call to a user-supplied address is executed.
The callee address of an external message call can be set by the caller. Note that the callee can contain arbitrary code and may re-enter any function in this contract. Review the business logic carefully to prevent averse effects on the contract state.
## Unchecked Call Return Value
- SWC ID: 104
- Severity: Low
- Contract: Unknown
- Function name: `thisisfine()`
- PC address: 661
- Estimated Gas Usage: 1361 - 35972
### Description
The return value of a message call is not checked.
External calls return a boolean value. If the callee contract halts with an exception, 'false' is returned and execution continues in the caller. It is usually recommended to wrap external calls into a require statement to prevent unexpected states.
## External Call To User-Supplied Address
- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `callstoredaddress()`
- PC address: 779
- Estimated Gas Usage: 687 - 1298
### Description
A call to a user-supplied address is executed.
The callee address of an external message call can be set by the caller. Note that the callee can contain arbitrary code and may re-enter any function in this contract. Review the business logic carefully to prevent averse effects on the contract state.
## Unchecked Call Return Value
- SWC ID: 104
- Severity: Low
- Contract: Unknown
- Function name: `callstoredaddress()`
- PC address: 779
- Estimated Gas Usage: 1405 - 36016
### Description
The return value of a message call is not checked.
External calls return a boolean value. If the callee contract halts with an exception, 'false' is returned and execution continues in the caller. It is usually recommended to wrap external calls into a require statement to prevent unexpected states.

- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `reentrancy()`
- PC address: 858
- Estimated Gas Usage: 709 - 1320
### Description
A call to a user-supplied address is executed.
The callee address of an external message call can be set by the caller. Note that the callee can contain arbitrary code and may re-enter any function in this contract. Review the business logic carefully to prevent averse effects on the contract state.
## Unchecked Call Return Value
- SWC ID: 104
- Severity: Low
- Contract: Unknown
- Function name: `reentrancy()`
- PC address: 858
- Estimated Gas Usage: 6441 - 61052
### Description
The return value of a message call is not checked.
External calls return a boolean value. If the callee contract halts with an exception, 'false' is returned and execution continues in the caller. It is usually recommended to wrap external calls into a require statement to prevent unexpected states.
## State change after external call
- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `reentrancy()`
- PC address: 869
- Estimated Gas Usage: None - None
### Description
The contract account state is changed after an external call.
Consider that the called contract could re-enter the function before this state change takes place. This can lead to business logic vulnerabilities.
## External Call To User-Supplied Address
- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `calluseraddress(address)`
- PC address: 912
- Estimated Gas Usage: 335 - 616
### Description
A call to a user-supplied address is executed.
The callee address of an external message call can be set by the caller. Note that the callee can contain arbitrary code and may re-enter any function in this contract. Review the business logic carefully to prevent averse effects on the contract state.
## Unchecked Call Return Value
- SWC ID: 104
- Severity: Low
- Contract: Unknown
- Function name: `calluseraddress(address)`
- PC address: 912
- Estimated Gas Usage: 1055 - 35336
### Description
The return value of a message call is not checked.
External calls return a boolean value. If the callee contract halts with an exception, 'false' is returned and execution continues in the caller. It is usually recommended to wrap external calls into a require statement to prevent unexpected states.

- Estimated Gas Usage: 1138 - 1749
### Description
Anyone can withdraw ETH from the contract account.
Arbitrary senders other than the contract creator can withdraw ETH from the contract account without previously having sent an equivalent amount of ETH to it. This is likely to be a vulnerability.

# Analysis results for test-filename.sol
## Unchecked Call Return Value
- SWC ID: 104
- Severity: Low
- Contract: Unknown
- Function name: `_function_0x141f32ff`
- PC address: 618
- Estimated Gas Usage: 1113 - 35865
### Description
The return value of a message call is not checked.
External calls return a boolean value. If the callee contract halts with an exception, 'false' is returned and execution continues in the caller. It is usually recommended to wrap external calls into a require statement to prevent unexpected states.
## Use of callcode
- SWC ID: 111
- Severity: Medium
- Contract: Unknown
- Function name: `_function_0x141f32ff`
- PC address: 618
- Estimated Gas Usage: 389 - 1141
### Description
Use of callcode is deprecated.
The callcode method executes code of another contract in the context of the caller account. Due to a bug in the implementation it does not persist sender and value over the call. It was therefore deprecated and may be removed in the future. Use the delegatecall method instead.
## Delegatecall Proxy To User-Supplied Address
- SWC ID: 112
- Severity: Medium
- Contract: Unknown
- Function name: `_function_0x9b58bc26`
- PC address: 849
- Estimated Gas Usage: 1176 - 35928
### Description
The contract delegates execution to another contract with a user-supplied address.
The smart contract delegates execution to a user-supplied address. Note that callers can execute arbitrary contracts and that the callee contract can access the storage of the calling contract.

## External Call To User-Supplied Address
- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `_function_0xeea4c864`
- PC address: 1038
- Estimated Gas Usage: 477 - 1229
### Description
A call to a user-supplied address is executed.
The callee address of an external message call can be set by the caller. Note that the callee can contain arbitrary code and may re-enter any function in this contract. Review the business logic carefully to prevent averse effects on the contract state.
## Unchecked Call Return Value
- SWC ID: 104
- Severity: Low
- Contract: Unknown
- Function name: `_function_0xeea4c864`

### Description
The return value of a message call is not checked.
External calls return a boolean value. If the callee contract halts with an exception, 'false' is returned and execution continues in the caller. It is usually recommended to wrap external calls into a require statement to prevent unexpected states.

# Analysis results for test-filename.sol
## External Call To User-Supplied Address
- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `callchecked()`
- PC address: 196
- Estimated Gas Usage: 599 - 1210
### Description
A call to a user-supplied address is executed.
The callee address of an external message call can be set by the caller. Note that the callee can contain arbitrary code and may re-enter any function in this contract. Review the business logic carefully to prevent averse effects on the contract state.
## External Call To User-Supplied Address
- SWC ID: 107
- Severity: Medium
- Contract: Unknown
- Function name: `callnotchecked()`
- PC address: 285
- Estimated Gas Usage: 621 - 1232
### Description
A call to a user-supplied address is executed.
The callee address of an external message call can be set by the caller. Note that the callee can contain arbitrary code and may re-enter any function in this contract. Review the business logic carefully to prevent averse effects on the contract state.
## Unchecked Call Return Value
- SWC ID: 104
- Severity: Low
- Contract: Unknown
- Function name: `callnotchecked()`
- PC address: 285
- Estimated Gas Usage: 1339 - 35950
### Description
The return value of a message call is not checked.
External calls return a boolean value. If the callee contract halts with an exception, 'false' is returned and execution continues in the caller. It is usually recommended to wrap external calls into a require statement to prevent unexpected states.
