Ethereum decompiler

Panoramix

This is an EVM decompiler.

It's is a fork of the Panoramix original repo that's not maintained actively by its author anymore: https://github.com/eveem-org/panoramix.git

The goal of this fork is to maintain Panoramix in a decent shape, fix some crashes, implement missing opcodes... I also got rid of the "tilde" syntax that was using a custom python encoding and use vanilla Python instead. And I made it a proper python package that can be imported. There is also a better support of timeouts, as instead of stopping entirely we will fallback and print whatever we decompiled even if it's not complete.

The code quality is still not great and the software is complex, it's mostly reserved for advanced users.

Installation

$ pip install panoramix-decompiler

Running

You can specify a web3 provider using the environment variable WEB3_PROVIDER_URI. In this case a local provider was set.

$ WEB3_PROVIDER_URI=http://localhost:7545 panoramix 0x0d94D81FD712126E7f320b5B10537D01d6a01563

You can also provide the bytecode for decompilation.

$ panoramix 6004600d60003960046000f30011223344

Examples

I have decompiled all of mainnet, and make sure to decompile again on the latest Panoramix version from time to time.

You can access decompilations using Oko: https://oko.palkeo.com/

Here is an example for cryptokitties: https://oko.palkeo.com/0x06012c8cf97BEaD5deAe237070F9587f8E7A266d/code/

Caveats

Windows is not supported currently.

Changelog

0.5.0

• Added support for the BASEFEE opcode.
• Updated bytecode database / ABI definitions.
• Ability to decompile the Solidity-generated Panic reverts.
• Lots of simplification / code cleanup.
• Moved to Poetry as the dependency management tool.

panoramix's Issues

wrong log parameters

decompile Wrapped Ether (WETH) contract on main chain.
decompilation = decompile_address('0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2', None)

It gives
log Transfer( address from=amount, address to=caller, uint256 value=recipient) which should be log Transfer( address from=caller, address to=recipient, uint256 value=amount)

I also found the log reco in the trace is strange too.
('log', ('param', 'amount'), 100389287136786176327247604509743168900146139575972864366142685224231313322991, ('param', 'sender'), ('param', 'recipient'))
I guess it should be:
('log', 100389287136786176327247604509743168900146139575972864366142685224231313322991, ('param', 'amount'), ('param', 'sender'), ('param', 'recipient'))

Uncomplete decompilation

Hi,
I was trying some panoramix features when I tried to decompile this smart contract :
https://etherscan.io/address/0x1d3b7e1afcf4afd95f8f28075f2e49a571dedb56#code

Fortunately enough, the owner published the contract source code so I could compare.
I got this result :

I think it's fair to say that the output is a bit short considering the bytecode size and compared to the published source code.
The 'bug' can be replicated on etherscan, as they also use panoramix (the result is even shorter):

https://etherscan.io/bytecode-decompiler?a=0x1d3b7e1afcf4afd95f8f28075f2e49a571dedb56

I have no idea what is going on and I'm sure not competent enough to try resolving this.
I really wanted to open an issue here when I saw that the bug was also occuring on etherscan side, if someone can fix this, it will also benefit etherscan and its numerous users.

https://www.eveem.org/ is down :'(

You define best_score but you don’t really use it. Is this a bug?

Do you want the one with the highest score or the last one with a score？

Well done

Look forward to your reply soon please

Weak documentation

Hi, can you pls provide some documentation on how to get an output from panoramix. I am using subprocess to run the command, and wanting to retrieve decompiled functions form it. Everything is ok except I am getting some strange output.

Code:

@app.route("/", methods=["POST"])
def index():
    try:
        data = flask.request.json
        address = data['address']
        process = subprocess.run(['panoramix', address], capture_output=True)
        print(process)
        return address
    except Exception as e:
        return flask.Response(status=400)

Output I want:

Output I get:

Timeout Error and TypeError

Panoramix Issue

We use python 3.8.13 versions and the environment is Linux Ubuntu20.04

1. Timeout Error

   1. We found that Panoramix often throws timeout exceptions when the number of contract parameters is high in the decompiled expressions. We found that the complexity of algorithm parsing in this part of the code processing logic grows exponentially with the number of parameters, and when the number of parameters is large, the speed of code processing increases greatly, leading to timeout exceptions.

   for a given expression, returns variants of it with each value being 0 or 2^256-1
   
   e.g. for ('ADD', ('mem', 64), ('mem', 256))
        returns
           ('ADD', 0, 0),
           ('ADD', 0, MAX_number),
           ('ADD', MAX_number, 0),
           ('ADD', MAX_number, MAX_number)

   b. 我们在测试这个代码的时候遇到了这类错误

2. TypeError: can only concatenate tuple (not ""int"") to tuple

Decompiled contract contains escape characters to highlight syntax

Panoramix produces decompiled contracts that contain escape characters to make the output look better in terminal, however, when redirecting it to the file, the code is hard to read. Unfortunately, this syntax highlighting is very tightly integrated in current version of panoramix so after a while I gave up on modifying the code. For those like me, who had the same issues I would recommend to strip escape characters out with sed.

panoramix contractAddress | sed 's/\x1B\[[0-9;]\{1,\}[A-Za-z]//g' > decompiled-contract

If anybody else has a better approach or you recommend other decompilation tool, let me know!

I sent some bitcoins to this wrong address. How can I recover it?

Failures running the tool in Windows

I'm having problems running this in Windows. I get a failure to decompile any of the bytecode, as compared with running it on Linux using the same input, which has no problem.

Hi

Panoramix fails to work not in main thread (and does not work in Windows)

ERROR:panoramix.decompiler:Problem with name()
Traceback (most recent call last):
File "/opt/homebrew/lib/python3.9/site-packages/panoramix/decompiler.py", line 177, in _decompile_with_loader
trace = dec()
File "/opt/homebrew/lib/python3.9/site-packages/timeout_decorator/timeout_decorator.py", line 75, in new_function
old = signal.signal(signal.SIGALRM, handler)
File "/opt/homebrew/Cellar/[email protected]/3.9.5/Frameworks/Python.framework/Versions/3.9/lib/python3.9/signal.py", line 47, in signal
handler = _signal.signal(_enum_to_int(signalnum), _enum_to_int(handler))
ValueError: signal only works in main thread of the main interpreter

This happens because panoramix in one place uses timeout-decorator library.
Precisely here in panoramix/decompiler.py

def _decompile_with_loader(loader, only_func_name=None) -> Decompilation:
    ...
      @timeout_decorator.timeout(60 * 3, timeout_exception=TimeoutInterrupt)
      def dec():
        trace = VM(loader).run(target, stack=stack, timeout=60)

timeout_decorator project actually describes this problem here:

Multithreading
By default, timeout-decorator uses signals to limit the execution time of the given function. This appoach does not work if your function is executed not in a main thread (for example if it’s a worker thread of the web application). There is alternative timeout strategy for this case - by using multiprocessing. To use it, just pass use_signals=False to the timeout decorator function:

But just adding use_signals=False would not work as the object is sophisticated enough and can not be pickled which is required by the multiprocessing module

So the full solution to this problem is:

1. pip install wrapt_timeout_decorator

2. add to panoramix/decompiler.py

from wrapt_timeout_decorator import timeout

3. replace

def _decompile_with_loader(loader, only_func_name=None) -> Decompilation:
    ...
      @timeout_decorator.timeout(60 * 3, timeout_exception=TimeoutInterrupt)
      def dec():
        trace = VM(loader).run(target, stack=stack, timeout=60)

with

def _decompile_with_loader(loader, only_func_name=None) -> Decompilation:
    ...
      @timeout(60 * 3, timeout_exception=TimeoutInterrupt, use_signals=False)
      def dec():
        trace = VM(loader).run(target, stack=stack, timeout=60)

This solves the failure to work not in main thread problem and should also solve not working in Windows problem (although I can not test the second statement)

I can submit a pull request, just let me know
