Along with this update of Cashie, CARV also introduces a new kind of developer stack: one that’s not just programmable, but agent-native. CARV x402 Facilitator: stateful and stateless endpoints for secure verification & settlement.

Cashie is architected around three foundational pillars: x402 Payment → Projects pledge funds via ERC-3009 signature (gasless), CARV ID (ERC-7231) → Maps handles to wallets, enabling verifiable rewards, ERC-8004 Agent → Executes campaigns autonomously (quests, raffles, payouts).
