Find Solidity engineers and maintainers

The list above ranks the most-starred public Solidity repositories, drawn from the public GitHub graph. Across 671 Solidity repositories in the public graph, the maintainers, top contributors, and recurring committers are a powerful signal for where Solidity expertise lives.

Behind every popular Solidityproject is a small group of people who actually shipped it. They’re the Solidityengineers, library authors, and infrastructure builders worth knowing - whether you’re hiring, partnering, or doing technical research.

Refolk turns this list into a search. Ask for “Solidity maintainers hiring”, “contributors to Solidity repos based in Europe”, or “companies whose engineers ship Solidity” and Refolk returns a ranked shortlist with the commits, repos, and profiles that earned each person a spot.

How this list is built

Refolk searched GitHub for public repositories whose primary language is Solidity, ranked them by stargazer count, and kept those with at least 100 stars. The list refreshes once a day.
