Buyers purchase with USDC and access content via Lit Protocol. After sale, sellers can withdraw or keep funds earning automatic yield. Vincent AI agents manage deposits, monitor rates, and optimize across Aave, Compound, Yearn. Real-time protocol optimization maximizes yield via a multi-protocol strategy.
