Google built A2A for agent coordination. Stripe built ACP for checkout. Coinbase built x402 for micropayments. But before any agent can pay, hire, or act — it needs to prove it's compliant. That's Layer 0.
The agentic economy is exploding in 2026. MCP has 97 million SDK downloads per month. x402 has processed 140 million transactions. Microsoft AGT has 9,500+ tests.
But every single one of these protocols has a fatal flaw: they assume the agent is already trusted. They assume Layer 0 exists. It doesn't.
CSOAI built Layer 0. We certify agents with Ed25519-signed Watchdog Certificates backed by BFT Council consensus. We enforce policies in real-time across 30 frameworks. We govern cross-border compliance across 6 jurisdictions. We verify payments with compliance pre-checks before x402, ACP, AP2, or MPP execute.
We're not just a compliance tool. We're the operating system for agent trust.
