Saturn

Saturn2022 is an onchain options platform for tokenized stocks, operating on Robinhood Chain. It offers options markets for 17 assets, including SpaceX, SPY, and major technology companies. The platform calculates option premiums directly in smart contracts using Black-Scholes, with spot prices from Chainlink and volatility estimated from the timing of the feed’s updates. Saturn2022 presents this approach as a way to price options without relying on market-maker quotes or offchain pricing services.

Its markets include calls backed by fully escrowed shares, eliminating margin calls and liquidation mechanisms for written options. For users seeking to supply assets, Saturn2022 also provides covered-call vaults: deposits are pooled to support option writing, and premiums are distributed to depositors in USDG. Vault shares are ERC-20 tokens, and users can withdraw assets that are not committed to open positions. The site provides live market data, contract details, documentation, and an app interface. Vaults are listed for assets including SpaceX, NVDA, TSLA, AAPL, and other major stocks; the displayed vaults are live but have no deposits until users contribute.
