This * can later be changed with {transferOwnership}. * * This module is used through inheritance. It will make available the modifier * `onlyOwner`, which can be applied to your functions to restrict their use to * the owner. abstract contract Ownable is Context { address private _owner; event OwnershipTransferred( address indexed previousOwner, address indexed newOwner ); constructor() { _transferOwnership(_msgSender()); } modifier onlyOwner() { _checkOwner(); _; } function owner() public view virtual returns (address) { return _owner; } function _checkOwner() internal view virtual { require(owner() == _msgSender(), "Ownable: caller is not the owner"); } function renounceOwnership() public virtual onlyOwner { _transferOwnership(address(0)); } function transferOwnership(address newOwner) public virtual onlyOwner { require( newOwner != address(0), "Ownable: new owner is the zero address" ); _transferOwnership(newOwner); } function _transferOwnership(address newOwner) internal virtual { address oldOwner = _owner; _owner = newOwner; emit OwnershipTransferred(oldOwner, newOwner); } } * @dev Implementation of the {IERC20} interface. * * This implementation is agnostic to the way tokens are created.

This behavior is nonetheless * conventional and does not conflict with the expectations of ERC20 * applications. * * Additionally, an {Approval} event is emitted on calls to {transferFrom}. * This allows applications to reconstruct the allowance for all accounts just * by listening to said events. Other implementations of the EIP may not emit * these events, as it isn't required by the specification. * * Finally, the non-standard {decreaseAllowance} and {increaseAllowance} * functions have been added to mitigate the well-known issues around setting * allowances.
