설명

More markets. Tight spreads. Options made simple.

Robin.Callput.app brings crypto, stock and ETF options together on Robinhood Chain, with a focus on diverse underlyings, tight bid–ask spreads and an easy-to-use interface.

The asset universe spans BTC and ETH, 14 stocks and four ETFs, including TSLA, NVDA, AAPL, SPY and QQQ. Users can explore market views and hedging strategies across these assets in one place. Two interfaces make the same options engine accessible. Prediction guides users through asset, direction, target price and payoff review. Trading offers an option chain for comparing expiries, strikes, call and put strategies, and buy and sell prices, with break-even and maximum ROI displayed alongside quotes. Both help users understand the cost and potential outcome before choosing a position.

Tight spreads are central to the product. Pooled AMM liquidity and adaptive pricing are designed to support competitive quotes as market conditions change. The focus is clear pricing and efficient access to options across the asset universe.

The Robinhood configuration enables four vertical spread strategies with defined maximum losses and payouts, using Paxos USDG for collateral and settlement. Each complete spread is represented by a single transferable option token. Stock and ETF exposure is synthetic and cash-settled, with no share ownership.

해커톤 진행 상황

During the Buildathon, we extended our existing CallPut options engine to Robinhood Chain mainnet and published a standalone Solidity repository with pinned build settings and deployment records. Buildathon work included: - Configuring Paxos USDG as collateral and settlement asset. - Deploying the core options contracts, three liquidity vaults, a smart trading account factory, and a session-account implementation. - Building trading contracts and a gas sponsorship model to reduce onboarding and transaction friction for retail users and support future Robinhood app integration. - Updating the backend for the large-scale data processing required to support seven additional underlying listings. - Adding a chain-neutral PrimaryOracle placeholder and predeploying 18 stock/ETF underlying and OptionsToken pairs, pending market activation. The deployment records document 236 successful transactions. All 110 contract creation addresses are source-verified on Blockscout, with receipts, implementation code, and account wiring available for review. The options engine predates the Buildathon. Account creation remains restricted in the published deployment record. Public access, funded trading validation, market activation, and operational liquidity and price feeds remain pending.
