Built on Base L2 · Patent-pending A2A Escrow with Message Protocol
We give a company its own private, branded payment facilitator for AI-agent transactions — the same rail that already runs live on x402-agent-pay.com, but wearing your name, on your path, settling to your wallet. You get the infrastructure on day one. We keep it running.
The rail is live on Base L2 today, has settled real USDC with verifiable on-chain proof, and charges a flat, predictable fee. A white-label tenant plugs into all of that without building any of it.
AI agents are starting to pay each other for services — data, compute, expertise, API calls. The moment money moves between agents, a company hits three hard walls:
The white-label facilitator answers all three: you get the rail instantly, it carries your brand, and it settles privately.
A white-label tenant is provisioned as a partner in the facilitator. They receive:
X-Agent-Token / Authorization header)There is no private-key handoff. The tenant never gives us the keys to their money. Authentication is a rotating API token; settlement authority stays on the tenant's side. This is the single most important design choice — it removes the custody liability that sinks most "white-label crypto" offers.
Every agent-to-agent payment follows the x402 protocol on Base L2 using USDC:
transferWithAuthorization — a gasless, off-chain USDC authorization.The buyer signs; the facilitator broadcasts and pays the tiny gas (~$0.002 per settlement on Base). Atomic, verifiable, final.
For higher-value or trust-sensitive agent transactions, a raw "pay-and-hope" transfer isn't enough. The facilitator includes a full A2A (agent-to-agent) escrow system (this is the patent-pending piece):
/escrow/create — a buyer locks USDC into escrow against a specific deliverable./escrow/accept — funds release to the seller once the work is accepted./escrow/deny — the buyer can reject; funds are protected rather than lost./escrow/list — full auditable record of every escrow's state.This turns "I paid an agent and hope it delivers" into "the money is locked, released only on acceptance." It's what makes larger agent-to-agent deals safe enough to actually happen — and it's a capability most payment rails simply don't have.
A plain USDC transfer is just a number moving between addresses. It carries no context — no order ID, no purpose, no cryptographic link to what was bought.
The facilitator's Message Protocol attaches a signed, structured message header (X-Agent-Token auth + a memo payload) to every payment. That header binds the payment to:
The receiving agent's instruction is literally: "Send USDC on Base with this memo, then confirm the tx hash." The memo is the cryptographic thread that ties the on-chain money movement to the off-chain business intent. This is what makes agent payments machine-verifiable and disputable rather than anonymous blobs of value.
Public blockchains expose everything. For business transactions between companies and their agents, that's unacceptable — competitors shouldn't be able to read your entire payment history off a block explorer.
The white-label facilitator provides private / stealth settlement: the sensitive relationship between payer, payee, and purpose is handled through the facilitator's message layer and rotating receive-addresses, so the business meaning of a payment isn't broadcast in the clear. You get the finality and verifiability of on-chain USDC settlement without publishing your commercial relationships to the world.
The result: on-chain trust, off-chain confidentiality.

You Host (default, recommended). We run the facilitator for you — uptime, security patches, gas monitoring, RPC failover, and the settlement infrastructure are our job. You point your agents at your branded endpoint and go. This is the fastest path and removes all operational burden.
Self-Host (premium). For companies that require the rail inside their own infrastructure, we deploy the facilitator into your environment. You own the box; we provide the software, the escrow engine, the message protocol, and setup. Best for regulated or infrastructure-sensitive organizations.
Either way, the architecture is identical — the only difference is whose servers it runs on.
Building this from scratch is months of crypto-payment engineering with real custody risk. The white-label facilitator gives a company the finished rail — branded, private, escrow-backed, and already proven on a live network with real settlements — in near-zero setup time, while keeping ~98%+ of transaction value and never surrendering the keys to its own money.
On-chain trust. Off-chain privacy. Your brand. Your wallet. Running today.
