# QuinEVM [16 solves] [388 points] (Unintended solution)
### Description```Do you even quine bro?
nc chall.polygl0ts.ch 4800```
Do you even quine bro?Nah, I dont. But I solved it :) (Unintended solution)
The objective of this challenge is to create a contract that return itself (quine) and the contract size has to be less than 8 bytes. We have to build the contract with EVM bytecode directly.
### quinevm.py :```python#!/usr/bin/env -S python3 -u
LOCAL = False # Set this to true if you want to test with a local hardhat node, for instance
#############################
import os.path, hashlib, hmacBASE_PATH = os.path.abspath(os.path.dirname(__file__))
if LOCAL:    from web3.auto import w3 as web3else:    from web3 import Web3, HTTPProvider    web3 = Web3(HTTPProvider("https://rinkeby.infura.io/v3/9aa3d95b3bc440fa88ea12eaa4456161"))
web3.codec._registry.register_decoder("raw", lambda x: x.read(), label="raw")
def gib_flag():    with open(os.path.join(BASE_PATH, "flag.txt")) as f:        print(f.read().strip())
def verify(addr):    code = web3.eth.get_code(addr)    if not 0 < len(code) < 8:        return False
    contract = web3.eth.contract(addr, abi=[ { "inputs": [], "name": "quinevm", "outputs": [ { "internalType": "raw", "name": "", "type": "raw" } ], "stateMutability": "view", "type": "function" } ])    return contract.caller.quinevm() == code
if __name__ == "__main__":    addr = input("addr? ").strip()    if verify(addr):        gib_flag()    else:        print("https://i.imgflip.com/34mvav.jpg")```
I solved this challenge with unintended solution
I saw this message in discord : ![](https://i.imgur.com/miGzfuY.png)
They solved it at 11:00 am (HK time), as contracts are deployed in rinkeby testnet, which is public, I explored blocks in a 5 minute timeframe before they solve it
Not much contracts are deployed during in that timeframe, this contract is the only contract that has deployed another contract : 
https://rinkeby.etherscan.io/address/0x03001a67c0841b681266baf4efe2e36896592506#internaltx

This is the contract deployed by that factory contract : 
https://rinkeby.etherscan.io/address/0x0ab5eaef94f507c53c95056eb85b9a2ca90ab2f9#code

It has only 7 bytes, so its likely the quine contract deployed by that team
