answer context
How does Shadow Float let agents buy x402 services before their own wallet is funded, and how are debt, repayment, and blocked-overreach receipts used on Arc?
Shadow Float is a mechanism that enables autonomous agents to obtain behavior-backed USDC spending lines on Arc, allowing them to purchase x402 services before their own wallet is funded. The system operates through three key receipt types: (1) Debt receipts that track the agent's outstanding balance, (2) Repayment receipts that document when the agent settles its obligations, and (3) Blocked-overreach receipts that prevent the agent from exceeding its authorized spending line. These receipts are recorded on Arc's settlement layer, which provides USDC-native stablecoin settlement with sub-second finality, creating an enforceable spend-control framework where agents can operate with provisional credit while maintaining transparent, auditable records of all transactions and repayments.
