Smart Contract Security Example

pragma solidity ^0.8.0;

contract SecureExample {
    // This modifier uses OpenZeppelin's secure patterns
    modifier onlyOwner {
        require(msg.sender == owner);
        _;
    }

    function safeTransfer() onlyOwner public {
    // Additional reentrancy guard
    require(!locked, "No reentry allowed");
    locked = true;
    // Transfer logic
    locked = false;
    }
}
