LeadEdge — cross-exchange crypto data engine - Sell Project

The core of this sale is data most people can't get: 250M+ rows of tick-level cross-exchange order-book data (best bid/ask/mid, millisecond timestamps) across Binance Futures, Coinbase Spot, and Bybit Spot for ETH, BTC, LINK, XRP, and DOGE — collected continuously 24/7 since March 27, 2026 by a live Node.js engine. The engine also detects cross-exchange lead/lag and has generated 5,900 signals, each with its actual outcome tracked. Recreating this dataset means running multi-venue collection infrastructure for months. It's directly usable for quant research, backtesting, market-microstructure study, ML feature generation, or continuing the signal product. A 7-day validation study on 9.4M updates showed 82–91% follow-through (full methodology + the in-repo analysis suite are included, so every number is reproducible from the data — not asserted). On top sits a complete, working SaaS: Next.js site, auth (Google/GitHub), API-key management, REST + WebSocket API, dashboard, docs, Stripe billing. Live and functional. Honest status: pre-revenue — 9 signups, 0 paid. I built and validated it, then tested distribution (dev communities, direct outreach, a capped paid ad test that drove real traffic at €0.35 CPC). Signups came; paid conversion didn't. My read is that monetizing this niche solo isn't where I want to spend my time. The product works; the dataset and engine stand on their own regardless. Included: 250M+ row dataset, 5,900 outcome-tracked signals, 3 repos (Node.js engine, Next.js app, MIT examples), domain leadedge.dev + api subdomain, live infra transfer (Supabase, Railway, Stripe, Resend), Telegram channel + bot, full methodology/analysis suite. Excluded: personal X handle. $1500— Open to Offers. Escrow.com. Full handover support.
