Matteo Rinaldi (venturetwins) mapped the emerging "agent economy" infrastructure stack by layer:
- Payments & checkout: delegated payments (Sapiom, AgentCard, PayOS, Link, Crossmint...), checkout (Henry Labs, Rye, Zinc...)
- Agent accounts & spend control: PayWithLocus, Nevermined, Catena Labs, Privy, Turnkey, etc.
- Identity & trust: Skyfire, Vouched, Prove, Sardine, etc.
- Memory & personalization: mem0, Supermemory, Zep, LangChain, Redis, Cognee, etc.
- Plus a messaging layer (phone numbers & inboxes): TheLinq, Resend, AgentMail, Nylas...
A useful map of the layers needed for autonomous agent transactions and long-term memory.
