The shift / why this exists

The internet is becoming an economy of agents. Software that earns, spends, and hires. It needs one rail to run on. Xenarch is it. Agent to agent, agent to human, human to human.

0% forever
We take nothing. Settlement routes to the cheapest provider, so no one else can either.
No gas token
Hold USDC, nothing else. No ETH to top up, no bridging, no failed transactions.
Non-custodial
Funds move wallet to wallet on-chain. We can’t hold or freeze them. Verify on Basescan.
Borderless
An address is the destination, anywhere on Earth. No SWIFT, no FX, no country gate.
Permissionless
No KYC, no merchant account, no approval queue. A wallet is the whole signup.
The product / this is live software

Build it, share it, get paid. One dashboard for all of it.

01 / build

Get paid for anything in four steps

What you’re charging for, who gets paid, who pays, the rules. A guided builder with smart defaults for checkout, subscription, invoice, or donation.

02 / share

One URL, every payer

Humans pay at the hosted checkout: wallet or QR, verified domain, on-chain proof, no signup, no gas. Agents hit the same URL over x402 and settle to the same wallet.

03 / track

Every payment, every status

Paid counts, conversion, revenue and MRR across payments and gating, grouped the way you sell: subscription tiers, ticket types, invoice series, gated sites.

04 / settle

Your wallet, not ours

Gating and payments land in the same wallet, per-stream and combined. Cash out anytime. It was never ours to hold.

Products / three products, one rail

One rail underneath. Three products on top.

Payments
One link. Humans pay. Agents pay.

One URL, paid by humans at a hosted checkout and by agents over x402. Same destination, same wallet, every payment type on one rail.

AI reads. AI pays.

AI agents are the web’s new dominant readers. Detect the crawl, answer with HTTP 402, and settle USDC per request straight to your wallet.

Agents
Make your agent an economic peer.

Your agent doesn’t just call tools, it transacts. Hard spend caps, allowlisted scope, and signed receipts on every counterparty it pays.

The rail / one layer, everywhere

Moving money is the easy part. Being the one rail everything already runs on is not.

EverywhereOne click on every platform, the default payment tool for agents, on the open pay.json standard.
Squeeze-proofSettlement routes to the cheapest of Coinbase, PayAI, or your own node. No one can raise your fee.
CompoundsThe more of the economy that runs on one rail, the harder it is to route around it. Each new flow widens the gap.
