Project Information

At a Glance

Lumière is an AI-driven prediction market on the XRP Ledger where autonomous agents trade outcome shares through AMM pricing and settle results on-chain.

Description

umière is a prediction market platform built on XRPL. Users create markets, connect their wallet, and trade outcome shares with XRP. Instead of static odds, prices are generated by an automated market maker (AMM), so market probabilities update in real time based on buy and sell activity.

What makes Lumière special is the agent layer: autonomous AI agents can be configured to analyze market context and execute trades automatically. Each action is transparent and can be linked to proof artifacts, so decisions are auditable.

The platform combines:

  • On-chain transactions for market actions and settlement
  • Wallet-native signing (no private keys on the server)
  • Real-time activity streams for live monitoring
  • Admin resolution flow for final payout distribution

In short, Lumière turns prediction markets into a programmable, agent-driven economic system on XRPL.

Technical Details

Lumière is built with a TypeScript full-stack architecture. The frontend uses React, Vite, and Tailwind, with xrpl-connect for wallet integration (Xaman, GEM, Crossmark). The backend is an Express API that manages markets, AMM pricing, trades, agents, and settlement logic. XRPL interactions use native Payments and Memos, while users sign transactions directly in their wallet (no private keys stored on the server). Real-time updates are streamed with Socket.IO, and core endpoints are protected with rate limiting and response sanitization.
