“Give the AI permission to make one exact payment—not control of your wallet.”

Safe autonomous spending before settlement.
Reliable autonomous execution after settlement.

The control loop

From intent to receipt,
with guardrails at every handoff.

A four-part path designed for autonomous buyers that still need human-grade boundaries.

  1. 01

    REQUEST

    An agent asks for a paid action

    The agent receives a precise x402 challenge before any money moves.

  2. 02

    APPROVE

    Armored Signer approves one exact payment

    The wallet credential stays local while policy binds the approval to the request.

  3. 03

    SETTLE

    GoPlausible settles on Algorand

    The facilitator coordinates the x402 payment group and network settlement.

  4. 04

    DELIVER

    ORA Gate commits and receipts the result

    The purchased action gets a durable receipt that can be replayed safely.

The proof, not a promise

with a receipt that holds.

Reconciliation

The ledger says
exactly what happened.

One transfer, one committed action, no duplicate economic effect.

The design principle

Autonomy without
unbounded authority.

ORA Gate proved one committed message without duplicate execution. That is the boundary: a durable, auditable action lifecycle—not a claim of universal exactly-once behavior for arbitrary external systems.
