CARV has integrated the x402 protocol into its Cashie 2.0 system, facilitating the conversion of social interactions into on-chain rewards. This integration allows for verifiable, automated, and privacy-protected transactions. Cashie, initially a social payment tool, is now evolving into a trustless coordination protocol that bridges influence and value. This development is part of CARV's modular agent infrastructure, utilizing CARV ID (ERC-7231), Model Context Protocol (MCP), and Protected Mind updates.
