Please review their action plans below:

1) igetgames has applied to start work (Funders only: approve worker | reject worker).

I've used IDA Pro for years and have recently been exploring Ghidra and it's rapidly growing ecosystem. This is a cool bounty and I'd love to give it a shot!
2) alagla has been approved to start work.

since Python is not supported for plugins in ghidra. I'll check how feasible is it implement a Java plugin. then build that in a separate repo maybe.

Learn more on the Gitcoin Issue Details page.

Ghidra plugins are only built with java. there's no python plugin support.

Hi @igetgames and @alagla, thank you for your interest in this bounty. Could you describe a bit more about your plan to solve this issue?

@alagla , my understanding is that Ghidra supports Jython, or alternatively ghidra-bridge can be used. If both solutions are not good, I am ok if the solution does something like:

• evm-cfg-builder exports the CFG in a json (or another format)
• the ghidra plugin loads the info, and displays it

[hackphobic]

@montyly correct me if i'm wrong, it seems to me Ghidra won't be able to load and analyze an evm bytecode without building an internal representation of that first. neither Jython or ghidra_bridge has the functionality to do that.

I can attempt a Java plugin that consumes .dot files from evm-cfg-builder and process the data in natively.

I'll start working when I get accepted on gitcoin.
Thanks

Hello, I wonder what is the status of this issue. I've built a Ghidra module for disassembling EVM bytecode and creating the CFG via evm_cfg_builder in https://github.com/adelapie/ghidra-evm. It would be great to receive feedback.
