Architecture

HoodOptions separates product surface from settlement backend so the venue can be demo-reliable today and fully on-chain tomorrow — same UX.

Phase 1 (current demo)

A TypeScript protocol engine mirrors vault shares, reserved capital, opens, and settlement. State persists locally. Markets and USDG use Robinhood Chain registry identities.

Phase 2 (on-chain)

Solidity vault + market contracts on Robinhood Chain bind to USDG and stock token addresses, with oracle round-bound settlement and a permissionless keeper. Full collateral — no liquidations.
