The Arbitrum Foundation concluded its New York City Founder House on March 8, awarding prizes across five projects selected from a pool of 473 applications. Held March 6 through 8 in New York, the event was part of Arbitrum Open House 2026, a four-city global program with a total prize pool of $1.8 million. Of the 88 teams invited to participate, 55 submitted projects for judging.

Winners and What They Built

Kustodia took first place and $60,000 for building an escrow-style payment system designed to reduce fraud in high-value marketplace transactions. Laytus claimed second place and $40,000 for a prediction market protocol focused on improving pricing accuracy when outcomes are correlated. EqualFi finished third with $20,000 for infrastructure that lets users create permissionless index tokens backed by tokenized real-world assets (assets such as loans, bonds, equities, real estate, and commodities that are represented on a blockchain). EqualFi had already deployed nine tokens on Robinhood Chain's testnet at the time of judging.

Two specialty awards rounded out the top five. Bond.Credit received a $50,000 Robinhood Chain Innovation Award for building a protocol that coordinates AI agents to allocate capital using standardized underwriting. Tilt Protocol earned a $100,000 award through the Founder in Residence track for an AI-driven management layer targeting tokenized RWAs on Robinhood's Layer 2 network. Winning teams were also offered entry into a mentorship program carrying an additional $100,000 in non-dilutive grants.

Two of the five awards went directly to RWA projects, and a third touched adjacent territory in AI-driven capital allocation. That concentration is not coincidental. Robinhood Chain, the lead sponsor among seven headline partners that also included Fhenix, LayerZero, Alchemy, Dune, GMX, and OpenZeppelin, is an Arbitrum Orbit-based Layer 2 blockchain (a network built on top of Ethereum using Arbitrum's technology stack) that launched its public testnet on February 10, 2026. It processed four million testnet transactions in its first week and is built specifically around compliance-embedded tokenized assets. Johann Kerbrat, General Manager of Robinhood Crypto, noted that Robinhood has already deployed roughly 2,000 tokenized stocks and ETF products for European customers. Robinhood has committed $1 million to the Open House 2026 program overall.

On-Chain Context

ARB, the Arbitrum network's governance token, was trading at approximately $0.099 as of March 11, down roughly 96% from its all-time high of $2.39, with a market cap near $590 million. The token price reflects broader market conditions but stands in contrast to continued network growth. Arbitrum holds about 35% of the Layer 2 market by total value locked, with TVL figures ranging from $17 billion to more than $20 billion depending on the measurement period. The network crossed 2.1 billion cumulative transactions in 2025, doubling from one billion in approximately 12 months. On-chain stablecoin supply grew 82% year-over-year to more than $8 billion. RWA tokenization on Arbitrum reached $1.1 billion, an 18-fold increase from 2024, with active loans growing 109% to $1.5 billion.

Regional Relevance: South Asia and Africa

The NYC event follows the Bengaluru IRL Hacker House held in October 2025, one of the first major on-the-ground Arbitrum builder events in South Asia, which distributed $70,000 in prizes. The Foundation's regional growth lead Aditi Chopra described the region's participants, saying that India's builders "move quickly, solve real problems, and set a high bar for product quality." India reports roughly 50% crypto wallet ownership among its online population. The Dubai leg of Open House 2026, scheduled from April 23 to May 14, is geographically accessible to South Asian builders looking for the next opportunity in the program.

The thematic focus of the NYC prizes also lands with practical weight in African markets. Nigeria leads global crypto wallet ownership at 84% of its online population, with South Africa at 66%. Escrow infrastructure (as Kustodia addresses) and accessible capital allocation (as Bond.Credit targets) map directly onto financial infrastructure gaps that have been widely observed across the continent, with blockchain-based tools offering potential paths to broader access. Arbitrum's RWA growth trajectory is especially relevant in markets where blockchain-based access to global equities and bonds represents a concrete improvement over what traditional brokerages offer.

One notable gap: the Open House 2026 four-city tour covers New York, Dubai, London, and Singapore. No African city is included, despite the continent registering the highest crypto adoption rates by wallet ownership of any region globally.

What Comes Next

The London and Singapore events are still ahead in the 2026 calendar. For builders who missed New York, the Dubai event runs April 23 to May 14; application details are available on the official Open House site. The Arbitrum Foundation has described the program as "built for founders who are serious about shipping, not just weekend builders," according to the Foundation's official X account, @ArbitrumDevs. Whether the next round of prizes continues the RWA-heavy thematic pattern will depend in part on which sponsors attach to those regional editions.
