修复建议

重入攻击

// 使用ReentrancyGuard
import "@openzeppelin/contracts/security/ReentrancyGuard.sol";

contract SafeContract is ReentrancyGuard {
    function withdraw() external nonReentrant {
        // ...
    }
}

tx.origin问题

// 错误
require(tx.origin == owner);

// 正确
require(msg.sender == owner);

注意事项

• 此工具提供基础静态分析
• 建议结合Slither、Mythril等专业工具
• 大额项目建议找专业审计公司
