Ethereum Signature Database

Hi there,over the course of a few months I’ve worked on a project called Etherface, an Ethereum Signature Database similar to 4Byte to decode function, event and error signatures. Unlike 4Byte however, it has two key features:

• It scrapes signatures 24/7 by itself without any user input by crawling / polling sites where Solidity code can be found (GitHub, Etherscan and 4Byte*)
• Provides source code associated with signatures, i.e. GitHub repositories and Etherscan URLs where these were scraped from to better understand what a given function, event or error signature might be used for

The project itself is open source and currently has scraped ~1.8 million unique signatures, more than 4Byte and samczsuns database. For what it’s worth I plan to provide these signature back to 4Byte at some point but for now all these signatures can be queried here. Hopefully this becomes handy for some people :)

* Technically 4Byte doesn’t provide source code, so only signatures are retrieved from there
