Building an Airdrop Hunter with Browser Automation

Description and use

An automated airdrop hunter using Playwright and LLM scans sources, fills forms, connects MetaMask, and registers tasks, discovering 19 airdrops in a single scan.

Problem

Manual airdrop participation is tedious: discovering sources, visiting sites, filling forms, connecting wallets, signing transactions, and tracking status.

Outcome

Discovered 19 airdrops in a single scan, 8 new airdrops identified, and automated browser interactions with Playwright successfully registered in a dynamic task registry.

Workflow

• Scan airdrop sources (airdrops.io, coinmarketcap, Twitter, Discord)
• Navigate to each airdrop site with Playwright
• Read page content and identify form fields
• Fill required fields using LLM‑derived selectors
• Click submit button
• Connect MetaMask wallet and sign transaction
• Register task in dynamic registry for periodic execution
