EDB 以太坊单合约交易调试工具

Idea

在刷题的时候遇到一类JOP(Jump-Oriented-Programming)的题目,fuzz或者调试这类题目缺少简单易用的工具,由此开发了一个简单的调试工具EDB(The Ethereum Debugger),利用debug_traceTransaction的rpc调用实现调用复现,目前仅支持单合约调试,由于关闭了Memory下载,因此大部分情况下不会出现geth崩溃的问题(参考QWB2020线下赛EthGaMe),Memory采用手动模拟实现,缺点是跨合约指令较为繁琐,目前没有精力全部模拟,只支持单合约交易的调试

环境要求

  1. python >= 3.6
  2. 开启debug_traceTransactionRPC调用的以太坊网络,推荐ganache
  3. pip install -r requirements.txt
  4. Windows平台没有经过测试,建议在Linux和macOS系统使用

说明

  1. 修改config.py中的ENDPOINT_URI
  2. 执行python edb.py TXHASH

调试命令

  1. n [delta]: 执行下一条或下delta条指令,可以为负数
  2. r: 顺序执行直到下一个断点或结束
  3. rb: 逆序执行直到上一个断点或起始
  4. b op=sha3;sta[-2]=0x100: 下条件断点,可用条件如下: a. op: 操作码 b. sta[xx]: 栈元素 c. sto[xx]: storage元素 d. pc: pc指针
  5. p mem|sto|sta: 打印全部Memory或Storage或Stack,限制大小可以在config.py中修改
  6. x mem[a:b]|sto[k]|sta[k]: 打印Memory或Storage或Stack上特定位置的数值
  7. db i: 删除第i个断点
  8. g step: 跳转到step位置
  9. j: 打印当前跳转栈
  10. ws k: 向后执行直到stack[k]的元素发生变化,用于追踪栈上元素来源
  11. q: 退出
