## Aliases
- Mythril
- Mythril Classic
- Symbolic Execution Analyzer
## Definition
Mythril 是基于符号执行Symbolic Execution的智能合约安全分析工具由 Consensys 开发。它通过将合约函数参数替换为符号变量,系统性地探索所有可能的执行路径,寻找可能导致资产损失或合约异常的状态。
## Key Features
- **符号执行**:不依赖具体输入值,遍历所有路径
- **深度扫描**:适合关键合约的深度分析(比 Slither 慢但更深入)
- **多种漏洞检测**:整数溢出/下溢、时间戳依赖、访问控制、逻辑漏洞
- **生成攻击场景**:自动生成可触发漏洞的交易序列
## Usage
```bash
# 基本分析
myth analyze src/MainContract.sol --solc-json mythril-config.json
# 高级配置
myth analyze src/MainContract.sol \
--execution-timeout 300 \
--max-depth 30 \
-o json > mythril-results.json
# 配合 Truffle
mythril truffle compile
mythril analyze --truffle
```
## Mythril vs Slither
| Dimension | [[Slither]] | [[Mythril]] |
|-----------|-------------|-------------|
| Method | AST-based static analysis | Symbolic execution |
| Speed | Fast | Slow |
| Depth | Surface-level | Deep path coverage |
| False positives | Low | Higher |
| Best for | Initial scan, high-confidence bugs | Critical functions, complex logic |
## Limitations
- 执行超时限制(通常 5-10 分钟)
- 路径爆炸问题(复杂合约分析不完整)
- 外部依赖处理有限(需要 mock
- 已被 MythX 商业化版本部分替代
