RedCarpetHQ is a regulated RWA marketplace that turns film profit participation rights into liquid, tradeable securities.

Investors buy in, trade peer-to-peer on an order-book market, and borrow against their holdings through ERC-4626 lending vaults. We capture 2.5% on every secondary trade. The protocol is built ground-up for agentic trading: no AMM, no matching engine. Bots read the order book and execute trades themselves.
