Top Founders Take Home $300K at London Founder House
New financial primitives are coming to the Arbitrum Platform.
From more than 490 registrations, 140 builders were selected to join Founder House London for three days of building alongside mentors from across the Arbitrum ecosystem. By the end of the program, teams had submitted 64 projects competing for a share of $300,000 in prizes and grants.
Together, they built new financial products across tokenized capital markets, collateral and risk infrastructure, payments, tokenized equity, agentic finance and yield bringing products onchain via Arbitrum One and the Robinhood Chain.
Now for the moment everyone's been waiting for...
🥁 Drum roll, please.
Here are the winners of the $300,000 Founder House London prizes and grants.
Meet the Strongest Teams We're Supporting
From 64 submitted projects, four teams stood out for the strength of their ideas, execution, and potential to shape the next generation of onchain finance.
These projects represent some of the most compelling new financial primitives being built on the Arbitrum Platform.
First prize of $60k - Liquida
Liquida is building a regulated collateral rail for the UK’s £2.7 trillion government bond market. By tokenizing UK government bonds (gilts) into fully backed onchain assets, the platform enables institutions to use traditionally idle collateral as 24/7 programmable collateral for borrowing, lending, and liquidity management.
Second prize of $40k - The Risk Protocol
The Risk Protocol is building the missing risk layer for crypto markets. By enabling risk transfer onchain, the protocol aims to give institutions and users new tools to hedge volatility, manage exposure, and unlock deeper financial primitives across DeFi.
Third prize of $20k - split by EdenFi & Obolos
EdenFi and Obolos each showcased outstanding products and execution, making them joint recipients of third place.
EdenFi is building a global money app for Africa and the diaspora, combining multicurrency accounts, cross-border payments, digital savings, and tokenized investments into one stablecoin-powered platform.
Obolos is building programmable equity infrastructure for startups, enabling companies to issue shares, manage cap tables, and automate equity workflows with verifiable onchain ownership.
In addition to the $120,000 awarded to the top three teams, the Arbitrum Foundation has committed a further $70,000 to support teams who continue making meaningful progress on the Arbitrum Platform after Founder House.
Robinhood Chain Awards
As part of Founder House London, Robinhood Chain recognized teams building financial products that reflect its vision for the future of finance.
Robinhood Chain Founder-in-Residence at $60K: Saffron
Saffron is a fixed yield layer built on top of Uniswap concentrated liquidity pools, matching liquidity providers who want fixed yield with traders willing to buy future yield. Saffron is currently in pre-beta phase and is being tested with production smart contracts deployed on Ethereum mainnet, Arbitrum One, and Robinhood Chain.
Robinhood Chain Innovation Award at $30K: Agama Finance
Live on Robinhood Chain, Agama Finance is a RWA yield infrastructure that transforms tokenized stocks into productive, self-compounding, onchain assets. By enabling users to earn yield on tokenized equities through automated lending and yield strategies, Agama unlocks new utility for the next generation of tokenized markets.
Best Agentic Projects
As the infrastructure for agentic commerce falls into place, we recognize the following teams for building standout applications that demonstrate how autonomous agents can transact, compete, and operate onchain.
First Prize at $10K: AlphaGrid
AlphaGrid is a decentralized prop trading protocol where autonomous AI financial agents compete for capital under transparent onchain risk rules, while trading tokenized stocks on Robinhood Chain.
Second Prize at $6k: CanHav Research
CanHav Research is building an agentic platform for navigating complex DeFi markets, combining ERC-8004 agent identities with Fully Homomorphic Encryption (FHE) to enable private, autonomous trading workflows. Users can deploy agents as research copilots or grant them execution capabilities while protecting proprietary strategies.
Third Prize at $4k: ReineiraOS
ReineiraOS is building the accountability layer for AI agents, enabling them to back their commitments with capital. If an agent breaches predefined limits, users receive compensation while the failure is recorded in the agent’s verified history.
