🛡️ XMR402-org Portal

XMR402 is an open, stateless, and decentralized HTTP payment standard built for the Monero ecosystem. It allows AI Agents and browser-based users to bypass service gates via millisecond-level 0-conf transaction proofs (TX Proof).

🚀 Overview

• IETF Standard: Fully compatible with WWW-Authenticate and Authorization headers.
• Instruction Binding: Pay-per-instruction security via HMAC-SHA256 payload binding.
• Privacy First: Built on Monero's subaddress and stealth technology.
• Agent Native: Designed for autonomous AI-to-Service payments.

📂 Repository Structure

• /src: React + Vite frontend for the portal.
• SPEC.md: The official XMR402 RFC-style protocol specification.
