HoodScan just finished its first full census of Robinhood Chain open source. We scanned GitHub for everything touching the chain, Robinhood's L2 built on the Arbitrum Orbit stack, and found 71 repositories. Of those, 50 met the bar for the index, and 26 are tier-1: projects built directly for the chain rather than ported to it.
The category split shows where builders see the opportunity. SDKs and Tools lead with 10 indexed repos, DeFi follows with 8, Trading Bots with 7, and RWA and Stocks with 4. AI and Agents plus Chain Core fill out the rest. For a chain whose pitch is tokenized stocks and real-world assets, tooling outnumbering finished apps is what an early ecosystem should look like.
What People Are Building
The top repo in the index is robinhood/faust, with 6,824 stars and a HoodScan Score of 137. The score combines stars, commit activity, tier, and community boosts, a formula we walked through in earlier coverage. Below faust, the curve drops off quickly: most tier-1 repos measure their history in weeks, not years, and star counts in the dozens are normal.
The Recently Listed feed makes that youth concrete. Fresh arrivals like labrinyang/lp-terminal, krillintel/krill, and itsfriedpotato/potatopad hit the index within days of their first public commits. Our indexing notes describe the pipeline: a scan finds a repo, a quality pass runs, and the listing goes live on the board.
Youth is the defining trait here. Most tier-1 repos are weeks old, and several shipped their first release after the chain went live. New L2s usually launch with a long tail of tooling forked from other chains; Robinhood Chain is drawing projects written for it from the first commit, which says more about conviction than any star count does.
Liquidity Arrived Before the Code
The code is not shipping into a vacuum. The Markets tab on HoodScan pulls live Robinhood Chain DEX pools from GeckoTerminal, refreshed every 60 seconds, and the volume is real: USDG did $106M in 24-hour volume, CASHCAT $23M, VIRTUAL $14M, TENDIES $9.6M. That on-chain activity matters for anyone deciding what to build next. Real pools with real fees mean a new protocol or bot has users to serve on day one, which is rare for a chain this young and a big part of why tier-1 repos keep appearing.
Quality control matters at this size, so farmed star-bot repos are filtered out before they ever reach the index. The 50 listed projects reflect actual work. Anyone can add a signal the honest way: Boost is a free +1, one per repo per day, no wallet needed.
The Early Window for Builders
For builders, the math is simple. With 26 tier-1 repos across six categories, most niches are thin enough that a solid project can become the reference implementation in weeks. No dominant aggregator, no standard wallet SDK, no default bot framework yet. The repos that claim those slots first are the ones everyone else will depend on later.
We will rerun the census as the index grows. The scan already surfaced 21 repos that did not make the cut this round, and some will graduate with a few more weeks of commits. The leaderboard updates continuously, so treat the numbers in this post as a snapshot, not a ceiling.
If you are building on Robinhood Chain, get your repo listed early. The ecosystem is young enough that a few weeks of steady commits can move a new project near the front of the leaderboard.
