Neroswap: a Privacy-First DEX & CEX Aggregator

How we built a real-time orderbook aggregator across 6 decentralized and centralized exchanges — with no KYC, no custody, and no tracking.

The Problem

If you want to trade Monero or Wownero today, your options are scattered across half a dozen exchanges — each with a different UI, different pair formats, and wildly different prices. Some are decentralized atomic swaps; others are no-KYC centralized platforms. Comparing prices means opening six browser tabs and doing mental math.

Neroswap fixes that.

What Neroswap Does

Neroswap is a real-time aggregator that pulls orderbook and ticker data from six exchanges and displays it in a single, unified dashboard. You can see best prices at a glance, filter by exchange type (DEX vs CEX) or coin (XMR vs WOW), and click directly through to the source exchange to trade.

The exchanges currently tracked are:

  • BasicSwap — SMSG-based atomic swaps for BTC, LTC, XMR, PART, WOW, FIRO, DASH, and more
  • Retoswap — P2P exchange for XMR fiat/crypto pairs, trades settle over Tor
  • Eigenwallet — BTC ↔ XMR trustless atomic swaps via Tor rendezvous
  • Nonlogs — No-KYC Wownero-focused exchange with WOW/BTC and WOW/USDT
  • CexSwap — Spot markets and AMM liquidity pools across 40+ coins
  • AltQuick — No-KYC altcoin exchange with 25+ BTC-quoted markets

Kraken reference prices are used to compute approximate USD values for every pair.

How the Data Pipeline Works

Neroswap runs a fleet of Python scrapers on a dedicated server. Each scraper targets one exchange and runs every 10 minutes via cron:

  1. Scraping — Each script queries its exchange via REST API, gRPC, HTML-over-Tor, or direct RPC. BasicSwap and Retoswap are scraped via local full nodes; Eigenwallet via its Tor onion; Nonlogs, CexSwap, and AltQuick via public APIs.

  2. Normalization — Raw data is transformed into a common JSON schema with fields like pair, price, amount, type (bid/ask), and source.

  3. Sync — The JSON files are rsync'd to a CDN edge server over SSH every 10 minutes, right after the scrapers finish.

  4. Serving — The neroswap.com frontend is a Next.js app using ISR (Incremental Static Regeneration). It fetches the JSON data from the CDN on each request with a 5-minute revalidation window, so the data is always fresh.

  5. Rendering — The frontend computes best bid/ask prices across all sources, applies Kraken USD reference rates, and renders sortable, filterable tables. Every row links back to the source exchange.

Privacy by Design

Neroswap has no user accounts, no cookies, no tracking pixels, and no analytics. There is nothing to log and nothing to sell. The entire site is a read-only dashboard — it never touches your funds or your identity.

All the DEX sources (BasicSwap, Eigenwallet) are fully decentralized with on-chain or cross-chain atomic settlement. The CEX sources (Nonlogs, CexSwap, AltQuick) are all no-KYC platforms. Retoswap trades happen entirely over Tor.

The Stack

  • Frontend: Next.js (App Router), React, TypeScript, Tailwind CSS
  • Scrapers: Python scripts with requests, grpc, and stem (Tor)
  • Data transport: rsync over SSH to CDN, served as static JSON
  • Infrastructure: Systemd services, cron scheduling, PM2 process management
