get-top-traders.js

get-top-traders.js

Scrapes DEXScreener’s “Top Traders” tab for any Solana token and extracts wallet addresses. Uses Patchright (a Playwright fork) with a real Chrome browser and NopeCHA extension to bypass Cloudflare protection.

Usage:

DISPLAY=:1 node scripts/get-top-traders.js <token_address>

Requirements:

• Chrome/Chromium installed
• NopeCHA extension in ~/.nova-browser/ profile
• A virtual display (TigerVNC, Xvfb, etc.) since NopeCHA only works in headed mode
• patchright npm package

How it works:

1. Launches a persistent Chrome context with the NopeCHA extension
2. Navigates to the token’s DEXScreener page
3. Waits for Cloudflare to be solved automatically
4. Clicks the “Top Traders” tab
5. Extracts wallet addresses from maker= URL parameters and Solscan links
