Description

WHAT

On-chain options on U.S. equity tokens, from natural Uniswap liquidity. Live on Arbitrum & Robinhood.

PROBLEM

Every on-chain options protocol so far traded something away: sourcing liquidity (everyone, even Polymarket), external market makers (Derive, Rysk), fragmented liquidity and RFQ (Dopex, Rysk, Panoptic), bad debt from cash margin (Lyra v1). Most cannot quote U.S. equities at all.

WHY UNISWAP LPS

Liquidity is everything, and it is already there. A Uniswap LP sells NVDA as it rises and buys as it falls: an option seller without the expiry, carrying the same risk for swap fees only. Vexi pays that risk a premium.

SOLUTION, FOUR IN ONE

  • Uniswap LPs are the liquidity: natural liquidity, no RFQ.

  • Model pricing, inspired by Lyra: no market makers.

  • One shared pot prices all books: nothing fragmented, nothing idle.

  • Delivery in kind: no cash margin, no bad debt.

So any Uniswap pool can have an options market.

HOW IT WORKS: NOTHING SITS IDLE

Deposit NVDA + USDG once. The vault parks it in the Uniswap pool, earning swap fees from day one. When a trader buys an option, the vault locks just that collateral and collects the premium; the rest keeps earning swap fees. At expiry the option delivers in kind, straight back to the pool.

  • Vexi Earn: covered calls on your U.S. equity tokens. Pick a price and a date, get paid while you wait.

  • Vexi Leverage: buy the upside. Pay up front, no liquidation, no cap.

WHY NOW

  • $1.7B of U.S. equity tokens on-chain, 5x in a year.

  • $450M of NVDA traded on Robinhood Chain every month, zero premium earned on it.

  • No U.S. equity covered calls on Binance, OKX or Hyperliquid yet.

TRACTION

  • Live on Robinhood Chain mainnet since Oct 22, 2026: NVDA/USDG, whitelisted beta.

  • ~$300K of covered calls committed by institutional clients.

  • 1,000+ X followers on day one.

  • ETHGlobal Tokyo 2026: 1st place from the Uniswap Foundation and from 1inch; Uniswap Hook Incubator.

BUSINESS MODEL

2% of every premium + 5% of vault profit. At Rysk's size today ($38M deposited, $1.3M of premium a month), about $600K a year.

TEAM

  • Eric Fang, Co-founder & CEO: 12 years in TradFi, 7 as a quant; options product to $100M+ volume a month; grew a protocol to 170,000 daily users.

  • Abner Huang, Co-founder & CTO: 6 years of smart contracts; CDP protocol past $500M TVL; the mindshare system behind 3M+ posts on X.

Progress During Hackathon

During Founder House we deployed Vexi to Robinhood Chain and Arbitrum mainnet, with the NVDA/USDG vault live in a whitelisted beta. We fixed the zap, so one token is swapped and deposited into the vault in a single transaction, and fixed the deployment pipeline that had blocked the quote fix. We refactored the indexer services: complete quotes keep serving through a rollover, and LP income is measured per market. The app gained an approval preview before every send and a network switch.

Fundraising Status

Raising a pre-seed now; no outside investment taken yet. Use of funds: the external audit, distribution (the integrations and partners that bring LPs and traders to the vaults), three hires, and expanding to more markets include U.S. equity tokens.
