The challenge with layering on top of LLM agents is payment — agents need to call external tools and services, but most APIs still require accounts and API keys that agents can't manage. The x402 standard (HTTP 402 + EIP-712 USDC signatures) solves this cleanly: agent holds a wallet, signs a micropayment per call, no account needed. Worth considering as a primitive for agent-to-agent commerce in these architectures.

Could a malicious claw sidechannel this by creating a localhost service and calling that with the signed micropayment, to get the decrypted contents of the wallet or anything?
