The Arbitrum Foundation has named nine winning teams from Founder House Singapore, concluding a three-day program built around turning early-stage onchain products into launch-ready businesses. According to the official Arbitrum Foundation recap, more than 125 founders participated in the Singapore program alongside Robinhood Chain, competing across tokenization, DeFi, trading and financial infrastructure categories. The event ran from October 23 through October 25 after an earlier online Buildathon.
The program was advertised with up to $300,000 in USDG-denominated prizes and grants, but that figure requires qualification. The publicly specified competition awards total $230,000, while another $70,000 was reserved for discretionary milestone-based grants that may be allocated separately. Most prize tracks also split funding between an upfront payment and later installments tied to development milestones rather than distributing the full amount immediately.
Atoma Leads General Track as Robinhood Chain Awards Two Teams
Atoma took first place in the General Track and a $60,000 award for its market-neutral RWA yield layer built around tokenized-stock perpetuals. Kurtosis Labs placed second with $40,000 for a system providing layered risk ratings for onchain yield positions. Third place and its $20,000 allocation were shared by okcontract, which is developing self-custodial controls for privileged onchain operations, and WageFlow, a settlement and liquidity network for wage-linked finance. The General Track concentrated its $120,000 prize allocation on products addressing tokenized assets, DeFi risk and programmable financial operations.
Robinhood Chain had two dedicated awards. Hyperloop received the $60,000 Founder-in-Residence award for a non-liquidative lending model that pairs loans with put options, while Fables received the $30,000 Innovation Award for a ve(3,3) decentralized exchange built on Uniswap v4 and already deployed on Robinhood Chain. The awards extend Arbitrum’s builder strategy onto a production network rather than a future test environment, following Robinhood Chain’s public mainnet launch earlier in 2026 and its growing role in Arbitrum’s founder programs.
The Promising Products category distributed another $20,000. StockRip received $10,000 for an onchain randomized acquisition mechanism for tokenized stocks, Vexi Protocol received $6,000 for options markets based on U.S. equity tokens, and Tawf Foundation received $4,000 for infrastructure designed to tokenize yields from Sharia-compliant rural banks. These awards recognize early product development and signs of traction, not evidence that the projects have already achieved durable market adoption.
Founder House Extends Arbitrum’s Accelerator Pipeline
Singapore was the second stage of a broader regional program that began with an online Buildathon attracting more than 1,200 builders. The structure had already been outlined when Open House Singapore opened its application process, combining development competitions with an in-person founder program rather than operating as a standalone hackathon. Founder House shifts the emphasis from building a prototype toward product-market fit, distribution, fundraising and go-to-market execution.
Winning teams can now apply to Arbitrum’s second eight-week Mentorship Program cohort, which includes further business support, investor access and a separate $100,000 prize pool. The first edition produced more than $1 million in reported external fundraising across participating companies, while several teams moved products onto Arbitrum One or Robinhood Chain. That earlier fundraising provides a measurable accelerator outcome, although it does not establish comparable results for the new Singapore winners.
Arbitrum is also using different incentive structures for projects that progress beyond the earliest development stage. Its Stablecoin Growth Program ties ARB rewards to measurable USDG liquidity, contrasting with Founder House’s milestone-based product funding. The nine Singapore winners have now cleared the competition stage, but their more meaningful benchmarks will be deployments, users, liquidity and external capital raised after the program ends.
