---| Rationalization | Why It's Wrong | Required Action |
|---|---|---|
| "Token looks standard, ERC20 checks pass" | 20+ weird token patterns exist beyond ERC20 compliance | Check ALL weird token patterns from database (missing return, revert on zero, hooks, etc.) |
| "Slither shows no issues, integration is safe" | Slither detects some patterns, misses integration logic | Complete manual analysis of all 5 token integration criteria |
| "No fee-on-transfer detected, skip that check" | Fee-on-transfer can be owner-controlled or conditional | Test all transfer scenarios, check for conditional fee logic |
| "Balance checks exist, handling is safe" | Balance checks alone don't protect against all weird tokens | Verify safe transfer wrappers, revert handling, approval patterns |
| "Token is deployed by reputable team, assume standard" | Reputation doesn't guarantee standard behavior | Analyze actual code and on-chain behavior, don't trust assumptions |
| "Integration uses OpenZeppelin, must be safe" | OpenZeppelin libraries don't protect against weird external tokens | Verify defensive patterns around all external token calls |
| "Can't run Slither, skipping automated analysis" | Slither provides critical ERC conformance checks | Manually verify all slither-check-erc criteria or document why blocked |
| "This pattern seems fine" | Intuition misses subtle token integration bugs | Systematically check all 20+ weird token patterns with code evidence |
| 常见误区 | 错误原因 | 必要措施 |
|---|---|---|
| "Token看起来符合标准，ERC20检查通过" | 除ERC20合规性外，还存在20余种特殊Token模式 | 检查数据库中的所有特殊Token模式（缺少返回值、零地址回滚、钩子等） |
| "Slither未发现问题，集成是安全的" | Slither可检测部分模式，但会遗漏集成逻辑 | 完成所有5项Token集成标准的手动分析 |
| "未检测到转账手续费，跳过该检查" | 转账手续费可能由所有者控制或为条件性的 | 测试所有转账场景，检查是否存在条件性手续费逻辑 |
| "已存在余额检查，处理是安全的" | 仅余额检查无法防范所有特殊Token | 验证安全转账包装器、回滚处理、授权模式 |
| "Token由知名团队部署，默认符合标准" | 声誉无法保证行为符合标准 | 分析实际代码与链上行为，不要依赖假设 |
| "集成使用了OpenZeppelin，肯定安全" | OpenZeppelin库无法防范外部特殊Token | 验证所有外部Token调用的防御模式 |
| "无法运行Slither，跳过自动化分析" | Slither提供关键的ERC合规性检查 | 手动验证所有slither-check-erc标准，或记录无法运行的原因 |
| "该模式看起来没问题" | 直觉会遗漏细微的Token集成漏洞 | 系统性检查所有20余种特殊Token模式，并提供代码证据 |
