Arbitrum's Open House Heads to Singapore with $115K Buildathon

The Arbitrum Foundation and Robinhood Chain are teaming up to host an Open House Buildathon in Singapore, offering $115K in prizes.

The three-week online buildathon begins on September 14 and will provide early-stage teams with product mentorship and technical support. The top three teams will receive a share of the $70K prize pool, with at least one spot reserved for a project built on Robinhood Chain.

In addition to the Buildathon, the leading teams will also earn places at a three-day, in-person Founder House in Singapore, where they will work with mentors and ecosystem partners to refine their projects. The Founder House will focus on product direction, value proposition, customer discovery, and go-to-market strategy.

The Open House program has already distributed $340K in New York and $300K in London earlier this year, and the Singapore event is part of a larger initiative that aims to support builders globally. Robinhood Chain's stake in the Open House program totals $1 million, with $415K earmarked for the Singapore event.
