Everyone is talking about ACP, UCP, and WebMCP.
OpenAI + Stripe built ACP. Google built UCP with Walmart, Visa, Mastercard. Chrome + Edge + W3C built WebMCP.
Big names. Massive resources. Real traction.
But they all solve the same problem: how an AI agent completes a purchase.
None of them answer the question that comes before:
→ How does an agent know it can TRUST the site it's about to transact with?
→ What stops an agent from executing on a phishing site?
→ Who proves what the agent actually did — and makes that proof public and verifiable?
→ What happens when an agent touches Stripe, Gmail, or ClickUp at 3am while you're asleep?
This is the gap. And it's not small.
It's called Web Agent Bridge (WAB).
Here's what makes it structurally different from everything else in the space:
——
/ / → Agent reaches checkout
→ Agent verifies trust → operates within governance → proves what it did → then reaches checkout
These aren't competing layers. WAB sits above all of them.

What WAB has shipped :
Ed25519-signed manifests + DNSSEC trust — cryptographic proof that a site is who it claims to be, at the protocol level, not just TLS
️ Agent Governance Layer — permission boundaries, human approval gates, kill switch, HMAC tamper-evident audit chain. An agent literally cannot exceed what you defined, even at 3am
⚓ ATP (Agent Transaction Primitive) — signed intent contracts, idempotent transactions, Ed25519-verifiable receipts. Public verification with zero authentication required. The buyer, seller, auditor, and court can all verify what happened — without trusting WAB
Ring 4 Trust Handshake — an 8-step cryptographic handshake protocol for sovereign AI agents. Already tested live by VEXR Ultra v4, which completed 3 cryptographic verification tests in under 100ms
ShieldLink — cryptographically signed links for banks and payment processors. Anti-phishing at the link level, before the user even clicks
⚡ Zero-Config Adoption — npx wab-init auto-detects Next.js / Nuxt / SvelteKit / Astro / Laravel / WordPress and scaffolds everything in under 60 seconds
Truth Layer + Reality Anchor — cross-site fact verification with weighted consensus to eliminate LLM hallucinations about prices, availability, and ratings
✅ 445/445 tests passing

To put this in context:
The agentic commerce market is moving fast.
AI-referred traffic to US retail sites grew 1,200% while traditional search declined 10%. Coinbase's x402 processed 165 million agent transactions in its first months.
Every major player is racing to define how agents buy.
But nobody has defined how agents TRUST — and how transactions become PROVABLE.
That's the layer WAB is building. And it's already live.

The tagline shifted this week from:
"The open AI↔Web protocol"
To:
"The trust + transaction layer for agentic commerce."
That's not a rebrand. That's a positioning statement that places WAB above every commerce protocol in the stack — as the infrastructure that makes all of them trustworthy.
