Find Solidity engineers shipping Blockchain

The list above ranks the most-starred public Solidity repositories tagged with the Blockchain topic, drawn from the public GitHub graph. Across 141 matching repositories, the contributors are a tight cluster of engineers with both Solidity chops and real Blockchain experience.

That overlap is rare. Most Solidity engineers haven’t shipped Blockchain, and most Blockchain 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 Blockchain maintainers hiring” or Solidity engineers shipping Blockchain 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 Blockchain topic, ranked them by stargazer count, and kept those with at least 25 stars. The list refreshes once a day.
