Everyone's reading this for the $115K prizes. We are reading it because Robinhood Chain is now a first-class citizen alongside Arbitrum One, with AI as a featured track. Tom Lee just said ETH has a "critical role in managing agentic-AI." This hackathon is that thesis being built in public. TradFi rails + agent economy on Ethereum infra. The pieces are moving faster than CT realizes 🙏📖

Three-week build cycle > weekend sprint. Better chance to ship something real.

what the GTM support looks like day to day vs the technical mentorship?

Replying to @arbitrum
The combination of technical support, GTM guidance and a path to Founder House makes this Buildathon worth watching.

3 weeks of sharpening MVPs for a shot at $115k split N ways, and the real flex is "spots to Singapore" doing more legwork than the prize pool. hope the GTM support includes a lesson in never announcing "novel AI x tokenization" with a straight face.

Three weeks of workshops, four feedback sessions, and one line item called "Builder Speed Dating." Somewhere a founder is about to pitch a tokenomics model to someone they just swiped right on.

Buildathons are quietly one of the better hiring funnels in the space. Three weeks of shipping in public says more than any interview loop, and a founder house in Singapore lands right where APAC engineering talent has been consolidating.

Three weeks and $115,000 in prizes can produce strong prototypes. Production readiness requires a different scorecard. Teams should prove authority controls, recovery, operating ownership and sustainable unit economics before the demo becomes infrastructure.

Incredible opportunity for early-stage teams! As we scale @Trestle_DeFi across @Arbitrum, @Base, and @0xPolygon , we know firsthand how vital this ecosystem support is. Good luck to all the founders building the future of finance! 🚀🛠️

the product and gtm layer is where most buildathons underinvest. shipping code is only half the test; teams should leave knowing who will use it twice after incentives end.

3 Weeks is tight but $115K makes it interesting. Good luck to the teams!

The strongest buildathon teams will leave with more than a pitch: a narrow product, a live contract and one transaction users can complete end to end.

The product and GTM support could be more valuable than the prize pool. I’d ask each team to leave with one live user workflow, a baseline, and evidence that the prototype improves completion or cost. That would make the buildathon a test of demand, not just a demo day.

are already-live Robinhood Chain projects welcome if we bring a new experiment? we’ve been building digital works with holder participation; product feedback would be especially useful.

Registering an idea for Robinhood Chain: a machine that stays fixed. Prototype has been in testing for fifteen years.
