The Unified Settlement Rail for the Agent Economy

Human and autonomous commerce infrastructure built on Base. Non-custodial settlement in under 2 seconds, zero rolling reserves, and programmable policy guardrails for the agentic era.

The Four Structural Shifts in Global Commerce

Modern commerce is experiencing its largest architectural transition since credit card gateways in 1996. OwnPay is engineered specifically for this convergence.

SHIFT 01

Machine-to-Machine Velocity

Autonomous AI agents make hundreds of programmatic decisions per second. Traditional card rails charge $0.30 fixed tolls per transaction, rendering autonomous sub-dollar micropayments economically impossible.

SHIFT 02

Zero Rolling Reserves

Legacy payment processors lock up 5% to 15% of merchant revenue for 90 days. OwnPay operates on non-custodial direct transfers; funds settle directly to merchant smart accounts in under 2 seconds.

SHIFT 03

Deterministic Intent Settlement

Every transaction is an immutable intent with dynamic FX locking (BDT, USD, EUR, INR) and one-time derived addresses, eliminating address collision and payment ambiguity.

SHIFT 04

Policy-Governed AI Autonomy

Agents transact freely within strictly pre-approved daily spend caps, velocity limits, and mandatory human approval workflows above defined value thresholds.

One Payment Core. Multiple Access Rails.

OwnPay converges human e-commerce interfaces and machine-native autonomous protocols into a single, unified settlement engine.

Human Payment Rail

Retail, POS & Webstore Commerce

Optimized for human customers purchasing goods, paying invoices, and checking out in e-commerce stores.

  • Physical Retail POS Counter with Dynamic QR (EIP-681)
  • Hosted Payment Links (ownpaylab.tech/pay) with fiat currency inputs
  • Seamless Drop-in Webstore Checkout Widget (ownpay-checkout.js)
  • Automated Settlement Splits across multiple partner wallets
Agentic Payment Rail

Autonomous Machine Commerce

Optimized for autonomous AI agents, API monetizers, and machine-to-machine financial execution.

  • 10 Model Context Protocol (MCP) Tools for AI Agent frameworks
  • x402 Pay-per-API micropayments with replay attack protection
  • Multi-key auth with granular scopes (payments:create, agents:manage)
  • Instant Agent Kill-Switch (Freeze/Unfreeze) emergency controls

Universal Intent & Settlement Flow

Both human and agentic payment requests converge deterministically into the same immutable core engine on Base Mainnet.

Institutional-Grade Security Controls

Built with defense-in-depth principles. OwnPay features strictly verified, production-hardened mechanisms without relying on custodial trust.

Non-Custodial Architecture

OwnPay never holds, pools, or custodies merchant funds. Payments settle directly on-chain from payer to merchant wallet.

Cryptographic Wallet Verification

Merchant ownership is verified via EIP-191 personal message signing before high-tier settlement rails are unlocked.

Replay Protection & Idempotency

x402 proofs and payment intent mutations are protected by database-backed idempotency guards preventing double-spends.

Policy Guardrails & Kill-Switch

Autonomous agents operate under strict daily spend ceilings. Merchant admins can freeze an agent instantly via the kill-switch API.

SSRF-Guarded Webhook Tester

Webhook endpoints strictly block localhost, private RFC1918 subnets, cloud metadata (169.254.169.254), and DNS rebinding attacks.

Granular Scoped API Keys

API keys utilize strict scope isolation (payments:create, agents:manage, sandbox:use) with distinct own_test_ and own_live_ prefixes.

Double-Entry Accounting Ledger

Immutable internal ledger records debit and credit pairs for human vs agentic volume with zero unaccounted discrepancy.

Tamper-Evident Audit Logging

Key creations, revocations, agent freezes, policy changes, and KYC events are timestamped and logged for compliance inspection.
