Solo execution
We are building a logistics rail for the x402 protocol ourselves
Working system, not slideware. Real money stays gated behind counsel, bank, and audit clearances.

The moment
Agents are becoming buyers.
Jul 2026
x402 goes institutional
x402 — the open protocol for machine payments over HTTP — became a Linux Foundation standard.
40 members
The x402 Foundation
Founding roster includes Visa, Mastercard, American Express, Stripe, Google, and AWS.
100M+
Payments processed
Through the protocol's reference facilitator — almost entirely micro-transactions (~$0.30 average). Invoice-scale money remains the white space.
One hundred million machine payments show the rail runs at machine speed — at an average of about thirty cents each. Invoice-scale money is the white space, and freight invoices are where we live.
Working system, not slideware
The Agent Factoring Rail ran end-to-end on a test chain.
01
An agent negotiates Net-30 terms
priced, signed, bound to an exact terms hash.
02
A factor approves them
through a seam built for factor networks.
03
A named human mints the escrow
agents cannot — the platform refuses them.
04
Delivery evidence verifies
against stored documents, checksums recomputed.
05
Funds release
citing the verification decision, on an append-only ledger.
In the recorded live run, two freight rails reached RELEASED end-to-end on our production billing engine — once straight through on verified delivery documents, and once through a dispute that a second, separately-empowered person resolved on the record. Then we attacked our own gates:
REFUSED · 401
An agent credential attempted the mint. The surface does not recognize software as an approver.
REFUSED · 400
An evidence bundle with fabricated document checksums — refused before any state changed.
EXACTLY ONCE
The mint was replayed. The engine returned the original recorded result — one approval mints one agreement, ever.
18/18
The escrow contract's full test suite on a live local test chain — including a hard refusal to sign on any real-money chain.
Sandbox disclosure: the recorded run uses a test chain, a valueless test token, a deterministic stand-in factor, and fictional parties. Every state transition, policy decision, and refusal is the real platform engine. No real money exists anywhere in the system today — by design, until the production gates pass.
Honesty as the position
What runs today. What is flagged off.
Runs today
- —The rail lifecycle above, end-to-end, on a test chain with a valueless test token.
- —The refusal gates: agent mint, fabricated evidence, replay — each held in the recorded run.
- —The freight operation underneath: production billing, EDI, a customer portal, live loads.
Flagged off
- —Real-money settlement. No production chain signing. No live facilitator against freight invoices.
- —Anything that would move customer or factor funds. Counsel, bank, and audit clearances come first.
Who is building this
A working freight operation, built in-house.
Nettrux is a California 3PL with production systems live today: a billing engine on production accounting, enterprise shipper billing including EDI, an operating factoring workflow, and a customer portal. The agent rail is built on those systems — we are not starting from a deck. Solo execution as of 2026-08-19: we build the rail ourselves.
Why this one holds
Compliance is the design, not the appendix.
- —Humans authorize every mint — agents submit, route, and surface; they never create a financial obligation.
- —Deterministic evidence policy — money moves on verified documents, or it doesn't move and a person rules on the record.
- —Append-only audit ledger — every transition, actor, and guard check, citable by hash.
- —Fiat in, fiat out — no crypto exposure for participants; the chain is evidence and coordination, not settlement.
- —No real money until the gates pass — counsel, banking, and audit sign-off are preconditions, not afterthoughts.
