Solana Token Explorer — Self-Hosted Solana Tracker API Frontend

A free, open-source backend proxy + frontend UI that wraps the Solana Tracker Data API and gives you a clean, fast interface to search, filter, and analyze Solana tokens — including pump.fun, Raydium, Orca, and more.

What is this?

The Solana Tracker Data API is one of the most complete real-time data sources for Solana tokens. This project is a thin backend proxy (Node.js/Express) that keeps your API key hidden from the browser, plus a full React frontend with:

• Token search with 60+ filters (liquidity, market cap, volume, risk score, holders, bundlers, launchpad, socials, and more)
• Token detail page — price, risk metrics, holder distribution, price changes across all timeframes
• OHLCV chart with multiple intervals (1s → 1w)
• Live trades feed with arb filtering
• Wallet explorer — see all tokens held with USD value
• PnL analyzer — realized/unrealized profit per token for any wallet
• Top Traders leaderboard — sort by total PnL or win rate

Quick Start

1. Get an API key

Sign up at solanatracker.io/data-api and grab your API key.

2. Clone & install

git clone https://github.com/YOUR_USERNAME/solana-token-explorer
cd solana-token-explorer

cd backend && npm install
cd ../frontend && npm install

3. Configure

# backend/.env
SOLANA_TRACKER_API_KEY=your_key_here
PORT=3001
FRONTEND_URL=http://localhost:5173
API_MIN_INTERVAL_MS=1100   # respect the 1 req/sec rate limit

4. Run

# Terminal 1 — backend
cd backend && npm run dev

# Terminal 2 — frontend
cd frontend && npm run dev

Open http://localhost:5173

Deploying to production

Option A — Same domain via nginx (recommended)

Frontend and backend live on the same domain. nginx proxies /api/* to Express:

server {
    listen 80;
    server_name yourdomain.com;

    # Frontend static files
    root /var/www/solana-token-explorer/frontend/dist;
    index index.html;

    location / {
        try_files $uri $uri/ /index.html;
    }

    # Proxy API requests to backend
    location /api/ {
        proxy_pass http://localhost:3001;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Backend .env:

FRONTEND_URL=https://yourdomain.com

Frontend — no extra config needed, VITE_API_URL stays empty.

Build frontend:

cd frontend && npm run build

---

Option B — Different domains (e.g. frontend on Vercel, backend on VPS)

Backend .env:

FRONTEND_URL=https://your-frontend.vercel.app

Frontend — create frontend/.env:

VITE_API_URL=https://api.yourdomain.com

Then build:

cd frontend && npm run build

---

Why a backend proxy?

The API key never leaves your server. The frontend talks to /api/* on your own backend, which forwards requests to data.solanatracker.io with the key in the header. Built-in rate-limit queue (configurable via API_MIN_INTERVAL_MS) serializes all outgoing requests so you never hit 429 errors even when multiple widgets load at once.
