Context.sol
This is a Solidity file that provides information about the current execution context, including the sender of the transaction and its data. It's used to provide a more secure way of accessing the sender and the data of a transaction, especially when dealing with GSN meta-transactions.
Context
This abstract contract provides secure access to the sender of the transaction and its data.
_msgSender
_msgSender() internal view virtual returns (address payable)
This method returns the sender of the transaction in a more secure manner.
Return Values
- address payable: The address of the sender of the transaction.
_msgData
_msgData() internal view virtual returns (bytes memory)
This method returns the data of the transaction in a more secure manner.
Return Values
- bytes memory: The data of the transaction.
Examples
Usage of Context
This example demonstrates the usage of the Context contract and its methods within another contract.
// This is a contract that inherits from the Context contract
contract MyContract is Context {
function performAction() public {
address sender = _msgSender(); // Securely get the sender of the transaction
bytes memory data = _msgData(); // Securely get the data of the transaction
}
}
