# Solidity API

|
|
## Context
|
|
|
|
_Provides information about the current execution context, including the
|
|
sender of the transaction and its data. While these are generally available
|
|
via msg.sender and msg.data, they should not be accessed in such a direct
|
|
manner, since when dealing with meta-transactions the account sending and
|
|
paying for execution may not be the actual sender (as far as an application
|
|
is concerned).
|
|
|
|
This contract is only required for intermediate, library-like contracts._
