EVeilM is a PoC EVM Bytecode Obfuscator.
This tool helps you analyze and obfuscate EVM bytecode, enhancing the security of your contracts and protecting your intellectual property.
- Parse and disassemble EVM bytecode 🔍
- Obfuscate EVM bytecode 🦹♂️
To install EVeilM, follow these steps:
- Clone the repository:
git clone https://github.com/tit0uanf/eveilm.git- Navigate to the project directory:
cd eveilm- Install the required dependencies:
pip install -r requirements.txtTo use the EVM Bytecode Obfuscator, follow these steps:
Choose an input method:
$ python eveilm
Choose input method:
❯ Paste Bytecode
Select FileIf you choose "Paste Bytecode", paste the bytecode and enter the contract name:
Please paste the bytecode (might get truncated): 6080604052...
What is the name of the contract ? MyContractImportant
Make sure that the bytecode input contains both Creation and Runtime Bytecode
If you choose "Select File", select the file containing the bytecode under /resources/original:
Choose a file to obfuscate:
USDC.evm
❯ USDT.evm
WETH.evmNote
The obfuscated bytecode will be saved in the resources/obfuscated/<obfuscation_type> directory.
These techniques are PoC obfuscation methods.
ADD Opcode Stack Manipulation: Obfuscates ADD opcodes by introducing additional manipulations.
Function Signature Transformer: Transforms function signatures to hide their name from decompilers.
Control Flow Graph Spammer: Insert random fake control flow paths.
Jump Address Transformer: Obfuscate JUMP and JUMPI opcodes PC destination
