GitHub · X · Telegram · Robinhood Chain docs
I build the missing developer layer for Robinhood Chain — an Arbitrum Orbit L2 (gas ETH) with tokenized equities, Uniswap, and Morpho Earn. The repos below are the kit I use to connect, quote, index, and paper-trade NVDA / AAPL / SPY Stock Tokens against USDG.
Stock Tokens are not DTCC shares. They are Robinhood-issued ERC-20s with jurisdictional limits. See Stock Token documentation.
