x402 changes how agents move value. But it doesn’t solve trust. As AI agents begin interacting with external tools, financial systems, and each other, trust can no longer be assumed. Most function-calling today still relies on blind execution by providers. But that breaks down in autonomous, high-stakes workflows. Our x402 extensions introduce trustless compute for agent workflows. Every function returns a cryptographic proof of correct execution from a TEE or secure runtime so agents can verify results without exposing private data or internal logic, independently validate before acting, and safely chain untrusted components.
