answer context
How does an autonomous agent pay creators per citation using x402 floats on Arc?
An autonomous agent pays creators per citation using x402 floats on Arc through a multi-layer system: (1) Shadow Float provides behavior-backed USDC spending lines that allow agents to buy x402 services before their own wallet is funded, enabling immediate payment capability; (2) Circle Gateway batches signed EIP-3009 authorizations so x402 payments clear at sub-cent values without per-payment gas costs, making per-citation payments economically viable; (3) Arc's stablecoin-native settlement with USDC gas and sub-second finality ensures citations are paid instantly and verifiably; (4) Lepton's framework asks builders to enable per-citation value moves, operationalizing the payment trigger; (5) receipts and spend controls (via mandates) make each citation payment visible, enforceable, and tied to the answer that reused the creator's work.
