ethereum-bytecode-analyzer

Find contracts in the Ethereum blockchain, analyze its bytecode and filter by JSON custom rules

This project is not ready yet. Work in progress...

Discontinued at the moment. There are already similar tools that I cannot catch up

It supports (or will):

Done

• Bytecode disassembling
• Control Flow Graph (static)
• Control Flow Graph (dynamic/symbolic)
• Keeps a trace of every word used as output/input of any opcode involved in the execution of a function

In progress / partial

• Blockchain navigation
• Ethereum Virtual Machine implemented
• Symbolic execution
• Execution and analysis of all possible paths changing the values of the configured inputs

Future/ Wanted

• Process engine to filter via custom rules
• Can check if there are stack elements at the end of every execution and try to remove the unnecessary operations that introduced them, reducing the gas of deploying and execution
• Reproduce a given transaction from the blockchain and draws a graph with the EVM state in every step, allowing debugging in one go
