|
|

### 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`

|
|
|
|
### 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.
