Arbitrum Open House Dubai: Online Buildathon

Dubai stands at the crossroads of global innovation and ambition.
Arbitrum delivers the infrastructure powering millions of users and institutions worldwide.

Now, the two converge.

The Open House Dubai Buildathon invites developers, creators, and founders to build with Arbitrum — the most scalable and secure Layer 2 ecosystem in Web3.

Weeks of focused building.
One purpose: to turn ideas into reality.

DeFi. Gaming. Social. Tools.
Or something entirely new.

Build with Stylus or Solidity.
Deploy on Arbitrum One or your own Orbit chain.

Bring an existing product or start from scratch.
No barriers. No limits. Just build.

Top projects will gain exposure to the Arbitrum ecosystem, connect with regional leaders, and join a global network of builders defining the next wave of onchain applications.

We’ve built the infrastructure.
Now it’s your move.
