Robinhood Chain has more than a million token contracts. We can prove about a thousand teams are building on it. Hey Research Lab reads their code, releases and contract deployments and answers one question with evidence: who is still building, and what did they ship? Every claim links to its source. Price is context, never the verdict. Browsing needs no wallet, and nothing on HEY is for sale.
168 pull requests sent to 135 repositories we don’t own, 18 merged so far. When we read a team’s code to check what they shipped and find a bug we can fix, we send the fix: dead explorer links, wrong chain config, block-time maths, stale contract addresses. Each one is the team’s call to take.
