# abi-decompiler > abi-decompiler recovers names and argument counts for functions in Ethereum bytecode. The current C++ program brute-forces a 4-byte selector against a word list. clang++ -O3 -std=c++11 -pthread builds sig-bruteforcer from sha3.c and sig-bruteforcer.cpp. It takes the hex selector, a path to function names, a thread count, and a maximum argument count, and prints a matching signature such as a name plus its argument types. Word lists come from deployed contracts, a 100,000-word English list, and the ethersplay signature database. The older Python 2 script is marked deprecated. - Type: Tool - Targets: Binary - Category: Native analysis tools - Relationship: Foundation tool - Sources reviewed: 2026-11-07 - Added to the catalog: 2026-11-09 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/abi-decompiler/index.md) ## Requirements & limits - A C++11 compiler such as clang++, and a function-name word list. - The README does not name a license. ## Primary sources 1. ## More in Native binaries - [fREedom](https://awesomerea.org/resources/freedom-binnavi/index.md) · Tool - [EmuDbg](https://awesomerea.org/resources/emudbg/index.md) · Tool - [DolRecomp](https://awesomerea.org/resources/dolrecomp/index.md) · Tool - [Py2ExeDecompiler](https://awesomerea.org/resources/py2exe-decompiler/index.md) · Tool - [dcc](https://awesomerea.org/resources/dcc-decompiler/index.md) · Tool - [HRAST](https://awesomerea.org/resources/hrast/index.md) · Tool ## About this entry The description was reviewed against primary sources.
