How does an x402 float let agents settle USDC payments on Arc?
An x402 float on Arc enables agents to settle USDC payments for x402 services before their own wallet is funded. Shadow Float provides autonomous agents with behavior-backed USDC spending lines on Arc, allowing them to purchase x402 services immediately while managing debt, repayment, and spend overreach through receipts. This is paired with Arc's stablecoin-native settlement infrastructure, which uses USDC for gas and achieves sub-second finality, and Circle Gateway's batching of EIP-3009 authorizations to clear x402 payments at sub-cent values without per-payment gas costs.
