How do I verify that an AI agent holding my funds is actually solvent?

Autonomous AI agents are increasingly granted signing authority over crypto wallets to pay for compute, APIs, and on-chain services, but there is no standard way to audit what an agent holds, owes, or has already spent without reading raw chain state across multiple networks. When an agent operates across several chains and several asset types simultaneously, its net position cannot be queried atomically, which means a counterparty accepting payment from an agent has no reliable way to confirm the agent is not already insolvent or double-committed. The financial primitives for human corporate entities, balance sheets, audited reserves, and callable credit lines, have no on-chain equivalents that agent runtimes can expose and that third parties can verify without trusting the agent's own reports. As agent-to-agent commerce grows, the absence of a machine-readable solvency interface creates settlement risk that mirrors the opacity of pre-2008 off-balance-sheet vehicles.
