Find Solidity engineers shipping Ethereum

The list above ranks the most-starred public Solidity repositories tagged with the Ethereum topic, drawn from the public GitHub graph. Across 331 matching repositories, the contributors are a tight cluster of engineers with both Solidity chops and real Ethereum experience.

That overlap is rare. Most Solidity engineers haven’t shipped Ethereum, and most Ethereum maintainers don’t write Solidity. The people on this list’s contributor graph are the ones who do both.

Refolk turns this list into a search. Ask for “Solidity Ethereum maintainers hiring” or “Solidity engineers shipping Ethereum in 2025” and Refolk returns a ranked shortlist with the commits, profiles, and projects behind each name.

How this list is built

Refolk searched GitHub for public Solidity repositories tagged with the Ethereum topic, ranked them by stargazer count, and kept those with at least 25 stars. The list refreshes once a day.
