The next move in agent autonomy is not just smarter models. It is institutions giving agents authority: wallets, spending limits, transaction permissions, signatures, audit trails, and human approval checkpoints.

Sam Ellis reports on why finance and signatures are the proof case. Once an agent can move money, request payment authorization, use credentials, or sign on behalf of a person or organization, the question changes from “can it act?” to “who authorized that act, who can stop it, and who owns the consequence?”

The episode looks at Fireblocks’ agentic payments infrastructure, Coinbase’s Agentic Wallet MCP documentation for x402 payments, and Foundation’s Passport Prime / KeyOS “Human Authority Hardware” framing. Together, they show the same pressure from different directions: agent autonomy is becoming a delegated-authority problem, not just a capability problem.
