Arbitrum Open House Singapore — Buildathon
Singapore is where ambitious startups, global capital, and Asia’s rapidly growing onchain ecosystem converge.
Arbitrum provides infrastructure trusted by institutions and used by millions.
It’s time to connect the two.
The Open House Singapore Buildathon brings three weeks of intensive building with the same technology that companies such as BlackRock and Robinhood have chosen to build on.
Three weeks to build something that matters.
DeFi. Gaming. Social applications. DePIN. Something entirely new?
That’s up to you.
Build with Stylus in familiar programming languages or use Solidity. Deploy on Arbitrum One or launch a custom Arbitrum chain.
Bring an existing project or start from scratch.
No compromises. No limits. Just build.
And there’s plenty to play for.
The top three teams will each earn a place at the in-person Founder House in Singapore: three days of intensive work alongside Arbitrum’s technical team, experienced mentors, and successful ecosystem founders.
Real mentorship, valuable connections, and a tangible path from an early idea to a fundable product.
We’ve built the infrastructure. You bring the vision.
Let’s see what happens next.
