The Ownable
contract is a base contract in Solidity that introduces the concept of ownership. It is used to ensure that only the owner of the contract can perform certain actions. This pattern is widely used in smart contracts to manage access control.
Features of the Ownable Contract
- Ownership Transfer: The owner can transfer ownership of the contract to another address.
- Access Control: Certain functions can only be executed by the owner.
- Safety: It prevents the loss of ownership due to errors in contract logic.
Example Usage
Here's a simple example of how to implement an Ownable
contract:
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/access/Ownable.sol";
contract MyContract is Ownable {
function onlyOwner() public view returns (bool) {
return msg.sender == owner();
}
}
In this example, the onlyOwner
function can only be called by the owner of the contract.
