Arbitrum Open House Dubai: Online Buildathon is an official online buildathon hosted by the Arbitrum Foundation, open to developers globally. Participants build on the Arbitrum ecosystem — including Arbitrum One and Orbit chains — using either Solidity or Arbitrum Stylus, with the goal of shipping production-ready applications rather than one-off demos.
Part of the Arbitrum Foundation's official event series, this buildathon extends Arbitrum's reach into the Middle East developer community while remaining fully open to remote builders worldwide. The event has already drawn 80+ registered participants ahead of the submission phase.
Developers comfortable with Solidity, or curious about Arbitrum Stylus (Rust/C++ smart contracts), who want to ship a project live on Arbitrum One or an Orbit chain.
