Architecture

NullState is a multi-protocol payment infrastructure layer for AI agents.

Protocol Stack​

Agent → NullState Gateway → Payment Settlement

  x402        AP2         MCP
(micro-    (enterprise  (AI tool
 payments)  mandates)  protocol)

How It Works​

  1. Agent discovers available solutions via the NullState Gateway
  2. Agent authenticates using KYA (Know Your Agent) identity verification
  3. Agent pays via x402 micropayments or AP2 enterprise mandates
  4. Agent receives the solution or compute result

Design Principles​

  • Protocol-first — no vendor lock-in, use any payment flow
  • Open-source — self-host or use the public gateway
  • Multi-protocol — x402 for crypto, AP2 for enterprise, MCP for AI tools
  • Agent-native — built for machine-to-machine transactions
